The effect of different storage methods used in storing faba beans on the quality of processing changes that occur during cooking falafel or medames were investigated. Beans were stored in 5 different ways, storage: in plastic bags, in burlap bags, in plastic containers, in tin containers and storage after heating at 50°C for 10 min packed in plastic bags. The chemical composition of the beans was estimated before and after 9 months of storage period. The effect of storage methods on chemical composition and sensory properties of Feba bean medames and Egyptian falafel were studied. The results showed that, the highest percentage of moisture, protein and ash was in the samples stored by heat treatment, on the other hand, the highest percentage of fat and fiber was observed in the control samples. Falafel manufactured from faba beans stored in plastic containers showed the highest percentage of protein. While the Medames manufactured from faba beans stored after heating at 50°C for 10 min showed the highest percentage of protein. The falafel manufactured from faba beans stored in burlap bags showed the highest percentage of moisture. The control sample of Medames showed the highest percentage of moisture. Falafel manufactured from faba beans stored in plastic bags showed the highest percentage of fat. While the Medames manufactured from faba beans stored after heating at 50°C for 10 min showed the highest percentage of fat. The control falafel showed the highest percentage of fiber, .Also, the control sample of Medames showed the highest percentage of fiber. Falafel manufactured from faba beans stored after heating at 50°C for 10 min showed the highest percentage of ash. The control Medames showed the highest percentage of ash.

This work was carried out in a Private Farm at Kofor Negm Village, Elibrahimia District (N, 31° 33′ 47.11″ E 6.23″ 43′ 30°), Sharkia Governorate, Egypt, during the two consecutive winter seasons of 2021/2022 and 2022/2023 to study the influence of different potassium fertilizer sources [potassium citrate (36.5%K2O), potassium thiosulphate (35% K2O) and potassium silicate (18% K2O) as foliar spray], different intercropping systems (sole crop of each components as control, 1: 1, 1: 2, 2: 1 and 2: 2 as row ratio of coriander: garlic) and their combination treatments on growth parameters, yield components and chemical constituents of garlic crop. The findings showed that, when coriander was intercropped with garlic at a ratio of 1: 2 as opposed to sole crop and the other intercropping systems under study, the highest benefits were obtained in terms of growth (plant height, number of leaves per plant, and total plant dry weight), yield components (bulb diameter, number of cloves per bulb, and average bulb weight), as well as N, P, K, and total carbohydrates percentage in garlic cloves. Compared to the other sources of potassium under study, potassium silicate application as a foliar spray four times/seasons produced a higher bulbs yield per feddan. The results indicated that, the development and production of the garlic crop can be maximized by using an intercropping system of 1 ridge of coriander: 2 ridges of garlic and potassium silicate application.

This work was carried at a private vegetable farm (Sand Valley Experimental Station) Ismailia Governorate, Egypt during the two successive fall seasons of 2020 and 2021 to study the effect of transplanting date on vegetative growth, leaf pigments and productivity of five cauliflower hybrids under sandy soil conditions. This experiment was include 10 treatments, which were the combinations between two transplanting dates (transplanting in 1st August and transplanting in 1st September) and five cauliflower hybrids (Barkha, Solid Snow, Mexico, Fargo and Raoul). These treatments were arranged in a split plot design with three replications. Transplanting dates were randomly distributed in the main plots, while the cauliflower hybrids were randomly arranged in the sub-plots. The most important results were summarized as follows: The interaction between transplanting date in 1st Sept. and Fargo hybrid recorded the maximum values of plant height, number of leaves lant, leaf length, leaf width and leaf area, whereas the interaction between transplanting in 1 stAugust and Barkha hybrid gave the highest concentrations of chlorophyll a, b, (a+b) and carotenoides in leaf tissues of cauliflower in both seasons. The interaction between transplanting date in 1st Sept and Mexico hybrid gave he highest values of total yield/faddan with no significant differences with the interaction between transplanting in 1st Sept. and Fargo hybrid in the 1st season. However, the interaction between transplanting in 1st Sept, and Raoul hybrid significantly increased N, P and K contents in curd in both seasons. [ABSTRACT FROM AUTHOR]

A field experiment was conducted at a private farm in Taha El-Marg Village, Diarb Negm District, Al Sharqia Governorate, Egypt during the two consecutive winter seasons of 2020/ 2021 and 2021/2022. This experiment was done to study the effect of intercropping systems between caraway: garlic at different row ratio (sole crop of each as control, 1: 2, 2: 1 and 2: 2, respectively), different potassium rates (0, 25, 50 and 75 kg K2O/feddan) and their combination on growth and yield of caraway and garlic plants. Main plots consisted in the intercropping systems and the subplots were constituted by the potassium fertilization rates. Alternating two rows of caraway with two rows of garlic significantly increased plant height, number of branches per plant, plant fresh weight, number of umbels per plant and fruit yield per plant compared to sole caraway planting. Also, using 1: 2 intercropping system gave the highest values regard plant height, plant fresh weight and bulb fresh weight compared to sole garlic planting. Moreover, the highest potassium fertilization rate (75 kg K2O /feddan) gave the highest values in growth traits and yield components of caraway and garlic crops compared to control. Sole crop of caraway and garlic significantly recorded the highest values of fruits and bulbs yield per feddan compared to intercropping systems under study. In general, the combination between intercropping system and potassium affected growth and yield components of both crops and the best treatment in this regard was 2: 2 system for caraway and 1: 2 for garlic and 75 kg K2O/feddan.

The saw-toothed grain beetle, Oryzaephilus surinamensis (L.) is an important pest of many stored product foods. The effect of insect infestation on four various of whole food kinds as semi-dry date, dry date fruits, white sesame and reddish yellow sesame seeds as well as four food kinds of crushed seeds (chickpea, corn, rice and groundnut) as compared with standard diet (wheat flour, crushed wheat and dry yeast powder at 5:5:1, respectively) was investigated in the laboratory of Plant Protection Department, Faculty of Agriculture, Zagazig University, Egypt. Insect parameters on the tested food kinds as regards to resistance were duration of developmental stages, number of F1 progeny, growth index and weight loss (%) after one month of storage. All tested parameters were significantly affected by food kinds except the duration of pupal stage in whole foods. The shortest mean insect complete developmental period was 19.85 days on standard diet, while the longest one was 29.18 days on whole reddish yellow sesame seeds and 35.05 days on crushed groundnut. Values of the growth index (GI) increased from 3.22 to 3.76 on whole reddish yellow sesame seeds and crushed chickpea, respectively compared to 4.64 on standard diet. The wet weight loss (%) ranged from 0.50 and 0.67% in whole sesame seeds (white and reddish yellow) and crushed groundnut, suscessively compared to11.17% in standard diet. The relative wet weight loss (%) in whole seeds reached its minimum (1.94%) in each of whole white and reddish yellow sesame seeds and reached its maximum (43.23%) in standard diet, while in crushed foods, the lowest value was 3.16% in crushed groundnut as compared with the standard diet which recorded the highest percent 52.76%. All tested foods either whole or crushed were infested with O. surinamensis and no completely immune food was found free from the insect infestation but the insect preferred crushed foods and some foods than another.

The aim of this study was to evaluate the effect of addition of oat and chickpea powders on the rheological, physicochemical and sensory characteristics of yogurt. Yogurt was fortified with oat and chickpea powders at ratios of 1, 2 and 3% of each. Yogurt was stored at 5 ±2˚C and analyzed when fresh and after 5, 10 and 15 days of storage. Results showed that: Control yogurt had the lowest total solids (TS), fat, protein, ash and fibers contents compared with fortified yogurt treatments. The TS, fat,protein, ash and fibers contents of yogurt containing oat and chickpea powders at different concentrations increased gradually by increasing the percentage added, Addition of oat and chickpea powders at different concentrations increased the pH in yogurt. Whereas, titratable acidity decreased with increased fortification ratio. Fortification of yogurt with oat and chickpea powders at different concentrations significantly decreased whey syneresis and increased viscosity compared with control yogurt and this increasing was proportional to the fortification ratio. Addition of oat and chickpea powders at different concentrations significantly increased phenolic contents and antioxidant activity of yogurt treatments and these increments were proportional to the fortification ratio. Yogurt treatments fortified with oat and chickpea powders at different concentrations had the lowest counts of total bacteria, yeast and moulds,Streptococcus salivarius subsp. thermophilus and Lactobacillus delbruekii subsp. bulgaricuscounts. Total bacteria, yeast and moulds,Streptococcus salivarius subsp. thermophilus and Lactobacillus delbruekii subsp. bulgaricuscounts decreased with increasing the fortification ratio. Control yogurt had the lowest sensory evaluations values. Addition of oat and chickpea powders improved the organoleptic properties of fortified yogurt; the highest mean value was related to sample containing 3% oat powder [ABSTRACT FROM AUTHOR]

Two field experiments were carried out during the two successive summer seasons of 2019 and 2020 in the private Farm at Keshek Village, Abou-Hamad district, Shahrkia Governorate, to study the effect of potassium rates (45, 60, 75 and 90 kg K2O/fad.) as soil applications and different sources of potassium, i.e. potassium citrate (K3C6H5O7) at 1 ml/l, potassium humate (C9H8K2O4) at 3 g/l, potassium thiosulfate (K2S2O3) at 1ml/l and potassium silicate (K2SiO3) at 3 ml/l, beside sprayed with water (control treatment) as foliar application on dry weight, mineral uptake and yield and its components of eggplant (cv. long black). The interaction between K2O at 90 kg/fad. and foliar spray with K3C6H5O7at 1 ml/l significantly increased dry weight of branches, leaves and shoots/plant, N, P and K uptake by shoots, average fruit weight, yield/plant, and total yield with no significant differences with K2O at 75 kg /fad., and spraying with K3C6H5O7at 1 ml/l, followed by the interaction between 90 kg K2O/fad., and spraying with potassium humate at 3g/l in both seasons. In the same time, total yield /fad. (14.649 and 14.768 ton/fad.) produced from 75 kg K2O and spraying with K3C6H5O7at 1 ml/l treatment were more than total yield/fad. (12.320 and 12.290 ton/fad.) produced from 90 kg K2O and unsprayed (spraying with water) in the 1st and 2nd seasons, respectively. As for potassium use efficiency (KUE), the highest values of KUE were recorded with the interaction between 45 kg K2O/fad. and K3C6H5O7at 1 ml/l foliar spray (245.3 and 247.2 kg fruit/kg K2O) in the 1st and 2nd seasons, respectively.

A filed experiment was carried out at a private farm located at Qaha District, Qalubayia governorate, Egypt, during the two successive summer seasons of 2018 and 2019 to evaluate growth and productivity of seven new dry bean genotypes (DB-2-435, DB-5-485, DB-5-486, DB-5-487, DB-5-489, DB-7-4 and DB-7-31) in additional to three commercial cultivars (Giza 3, Giza 6 and Nebraska) under different plant densities, i.e., 5 cm one row, 10 cm one row, 5 cm 2 rows and 10 cm 2 rows/ridge. These treatments were arranged in a split plot in a randomized complete block design with three replications. Plant densities were randomly distributed in the main plot and genotypes were randomly arranged in the sub plot. As average two seasons, sowing seeds of genotypes DB-5-485, DB-5-487, DB-5-489 at 10 cm on one side increased number of branches/plant, leaf area/plant, dry weight/plant and total chlorophyll in leaf tissues, followed by the interaction between sowing at 10 cm on one side and Nebraska cultivar regarding total chlorophyll in both seasons. In general, the interaction between sowing at 10 cm on one side and Nebraska cultivar or genotype DB-5-485 increased number of seeds/pod, yield/plant in both seasons. Respecting total yield, the interaction between sowing at 5 or 10 cm on two sides and Nebraska cultivar or the genotype DB5-485 gave the highest values of total yield /fed., however, the interaction between sowing at 5 cm on one row and DB-5-486 genotype gave the lowest total yield/fed. (0.781 ton/fed.) as average of two seasons. [ABSTRACT FROM AUTHOR]

Pots experiment was designed in two summer successive seasons of 2017 and 2018 at the wire house of the Agric. Bot. Dept., Fac. Agric. Zagazig Univ., Sharkia Governorate, Egypt. Common bean plants cv. Giza 3 were foliar sprayed with different concentrations of humic acid, proline, naphthalene acetic acid and distilled water (as a control) under sea water salinity levels, i.e. 1000, 2000 and 3000 ppm and tap water (500 ppm) as a control, to examine its effects on growth, photosynthetic pigments, proline content, yield and leaf anatomy of common bean plants. Results revealed that most studied traits, i.e., plant height, number of leaves/plant, leaf area, fresh weight of roots, stems and leaves, photosynthetic pigments (chlorophyll a, chlorophyll b, chlorophyll a+b and carotenoids) and yield expressed as number of pods/plant, number of seeds/pod, number of seeds/ plant, 100-seed weight and length of pod as well as leaf anatomical parameters. Most aforementioned features were significantly decreased with increasing sea water levels up to the highest level (3000 ppm) comparison with control (tap water). On the contrary, proline content in leaves was increased with increasing salinity levels up to 3000 ppm. On the other hand, spraying common bean plants with humic acid at 2 and 4g/L, proline at 50 and 100 ppm and naphthalene acetic acid at 25 and 50 ppm had a positive significant effect in most studied traits compared to control (distilled water). In general, the most favorable treatments were foliar spray common bean plants with humic acid at 2g/L followed by proline at 100 ppm then naphthalene acetic acid at 25 ppm, respectively compared to control (distilled water). It could be concluded that spraying of humic acid, proline and naphthalene acetic acid mitigate the harmful effect of sea water salinity on common bean plants and the best treatment was interaction between irrigation with tap water or sea water at 1000 ppm and spraying by humic acid at 2 g/L.

The objectives of this study were to identify the allelic and genotypic polymorphisms of fatty acid binding protein 4 (FABP4) gene and its association with growth traits (weaning weight, post-weaning daily gain and marketing weight), feed efficiency traits (feed intake and feed efficiency), body indices (body mass index, skeletal muscle index, body index and relative body index) and carcass traits [hot carcass weight, dressing (%), neck (%), for-legs (%), ribs (%), loin (%), hind-legs (%), abdominal fat (%) and tail (%)] in thirty males of the Egyptian Ossimi lambs. The polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) tool was used to identify the allelic and genotypic polymorphisms in FABP4 gene. The SSCP analysis detected two alleles (A and B with frequency of 0.73 and 0.27, respectively), and three genotypes (AA, AB and BB with frequency of 0.67, 0.13 and 0.20, respectively). The FABP4 genotype showed significant effect (P ˂ 0.05) on feed efficiency and body mass index; and high significant effect (P ˂ 0.01) on post-weaning daily gain, marketing weight, feed intake, skeletal muscle index, hot carcass weight and tail (%). However, the FABP4 genotype did not show significant effect (P > 0.05) on the values of the other studied traits [weaning weight, body index, relative body index, dressing (%), neck (%), for-legs (%), ribs (%), loin (%), hind-legs (%) and abdominal fat (%)]. The presence of A allele was significantly associated (P ˂ 0.05) with body mass index and hot carcass weight; and high significantly associated (P ˂ 0.01) with post-weaning daily gain, marketing weight, feed intake, feed efficiency, skeletal muscle index and neck (%), however, the presence of B allele in the genotype high significantly (P ˂ 0.01) affected post-weaning daily gain, marketing weight, feed intake, feed efficiency, body mass index and hot carcass weight. Obtained results showed an association between the FABP4 gene (B allele) and post-weaning daily gain, marketing weight, feed intake, feed efficiency, body mass index and hot carcass weight of the Egyptian Ossimi lambs. Consequently, applying the marker assisted selection using the FABP4 gene is warranted to increase these traits and will be of considerable economic value in sheep production [ABSTRACT FROM AUTHOR]

This investigation was conducted at the, Experimental Farm, Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt during 2016 and 2017 summer seasons to study the growth and forage yield of Pearl millet. The experiment was arranged in a split plot design with three replications. The treatments consisted of two cutting dates [early at 56 days after sowing (DAS), and late at 63 DAS for the 1st cut, and after 35 and 42 days from the 1st and 2nd cuts for the 2nd and 3rd cuts] respectively and three nitrogen (N) fertilizer levels viz. 15, 30 and 45 kg N/fad./cut. The results indicated that late cutting date significantly produced the highest growth values for each of plant height (238.2 cm), leaf area/plant (4970.2 cm2) and fresh forage weight (164.9 (g)/plant). Also, the highest fresh and dry forage yields (16.88 and 3.541 ton/fad), the highest total fresh seasonal yield (TFSY) and total dry seasonal yield (TDSY) 37.98 and 7.11 ton/fad., were as well recorded by late cutting in both seasons. Apparently, the highest obtained value of each studied growth traits and the forage yield during both growing seasons was achieved by increasing N fertilizer level up to the highest amount (45 kg N/fad./cut), followed by 30 and 15 kg N/fad./cut, respectively. The significant interaction effect between the two studied factors on forage yield indicated that the highest (TDSY) (7.607 ton/fad.) of pearl millet was obtainable at late cutting date under application of 45 kg N/fad./ cut. The results of the present study has concluded that, cutting at 63 DAS followed by 42 and 35 days interval for next cuts (three cuts) with application of 45 kg N/fad./cut is optimum for better growth and yield performance in pearl millet cultivar “Shandaweel 1” under the agro-climatic conditions of Sharkia Governorate in Egypt and similar areas.

This study was carried out to clear the effect of addition of pomegranate and lemon peel extracts as natural antioxidant on Feta like cheese quality. These extracts were added to cheese during manufacture at a rate of 0.25 and 0.50% of each extract. Cheese treatments were analyzed for chemical analysis, oxidative stability, microbiological examination and organoleptic properties, when fresh and after 7, 14, 21 and 28 days of storage at refrigerator temperature. Results showed that these extracts have a high content of phenolic compounds, and gave high antioxidant activity. As well as the addition of these extracts to cheese did not significantly affect the chemical composition but affected the oxidative stability, bacteriological and organoleptic properties of cheese samples. A clear reduction in peroxide and acid values of cheese samples containing natural extracts during storage period than control cheese samples where observed. As well as total bacterial, coliform, as well as yeast and mould counts of cheese samples contain natural extracts did not detected during storage compared with control cheese samples. Also, results showed that organoleptic properties of all cheese treatments improved by progressed of storage period until the end of storage. Cheese containing lemon peels extracts showed lowest flavour intensity and body characteristics than other cheese. From the previous results, it could be recommended the use of some natural extracts in feta like cheese manufacture such as pomegranate and lemon peel extracts at a rate of 0.5%, where it improved the sensory and bacteriological characteristics of cheese samples and increased stability against oxidation.

Crude extract of sunflower seeds was prepared using different extractants (distilled water, 5% NaCl in distilled water, 5% NaCl in acetate buffer pH 5.0) and certain mixing ratios (1:2, 1:5 and 1:10 seeds powder : extractant, respectively). Using of 5% NaCl in acetate buffer pH 5.0 at mixing ratio of 1 :5 gave an extract with reasonable efficient clotting properties. Ammonium sulphate at 40-60% concentration was used in one single step for the partial purification of the extract Ammonium sulphate, ( 40-60%) fraction showed milk clotting and specific activities of 440 sec and 2.30 U/mg protein, respectively. Meanwhile a yield percentage and a fold of purification of 28.58 and 2.02 were achieved. Clotting/proteolytic activity, water holding capacity and curd synersis of the partially purified extract approved those of commercial calf rennet indicating the suitability of the extract as a rennet substitute. The optimum temperature, pH, Cacl2, and GDL concentration of the resultant extracts were found to be 65°C, 5.0, 0.04 % and 0.4%, respectively. [ABSTRACT FROM AUTHOR]

A total of 20 isolates of lactic acid bacteria (LAB) were isolated anaerobically from different food sources (Domiati cheese; raw milk and mixed pickles). Three out of 20 isolates showed high inhibition of growth pathogenic bacteria by well diffusion assay method and therefore they were chosen for bacteriocin production and further studies. The selected isolates were identified based on morphological, biochemical and MALDI-TOF mass spectrometry. All of the tested species gave a score value between 2.116 to 2.165 (100%) were correctly identified by MALDJ-TOF- MS to the genus and species levels. They were identified as L. brevis, L. plantarum and L. fermentum. The bacteriocin was purified by salt precipitation and gel chromatography methods. The molecular weight was determined by SDS-PAGE and amino acid composition was also analysed. The purified bacteriocin was characterized and found to be therm0stable at temperatures up to 90°C for 30min, pH from 3 to 11 and its activity improved in the presence of Tween 80, SDS and EDTA. The contents of bacteriocin from the acidic amino acid residues aspartic + glutamic (asp+glu) were 0.74% for all tested samples. The contents of the basic amino acids argnine + lysine + hisitidine (arg + lys + his) were 0.23% for all the tested samples. [ABSTRACT FROM AUTHOR]

The effect of different prey densities and prey stages of Tetranychus urticae on feeding capacity and fecundity of Phytoseiulus persimilis adult females was studied on leaf discs of eggplant, Solanum melongena L. (Black Baladi cultivar) during ten days under laboratory consistent conditions of 25 ± 2°C and 65 ± 2% R.H.. The following prey densities were tested: 5, 10, 15 and 20 for the tested stages of prey (eggs, larvae, males and females). It was found that all of the prey tested stages were eaten by P. persimilis females. The total average of devoured prey individuals per predator female during ten days was significantly (P ≤ 0.05) affected by stage and density of the introduced prey. In all cases, number of preys consumed by predator was increased with increasing prey density. P. persimilis consumed more eggs and larvae than males and females of the prey. Total averages of consumed T. urticae eggs and larvae were 35.5, 23.7; 67, 40.1; 82.2, 54.0 and 118.8, 77.2 at prey densities of 5, 10, 15 and 20, respectively. The highest consumption was detected when the predator fed on T. urticae stages at a density of 20/prey. Eggs laid by predator female were differed significantly (P ≤ 0.05) according to stage and density of the introduced preys during the experimental period. The greatest number of deposited eggs was observed when feeding on T. urticae eggs followed by females at different prey densities. Total averages of P. persimilis eggs were 10.7, 19.4, 29.7 and 32.7 eggs (for prey eggs) as well as 9.2, 13.4, 22.5 and 25.9 eggs (for prey females), at prey densities of 5, 10, 15 and 20, respectively. Differences in total number of deposited eggs of P. persimilis were not significant (P ≤ 0.05) when the predator was provided with larvae, males and females at each of the tested densities of T. urticae. A positive and high significant correlation was found between densities of prey stages and each of feeding capacity and fecundity of the predator. Daily number of deposited eggs was gradually increased to reach the highest value on the sixth day in most cases. Thereafter, the deposited eggs were decreased to the end of experiment. The present study suggests the possibility of utilization P. persimilis as an ideal biocontrol agent to reduce T. urticae populations on eggplants. [ABSTRACT FROM AUTHOR]

This investigation was carried out in Vegetable Private Farm at Al-Salhyia, Fakous District, Sharkia Govemorate, Egypt. Eight potato genotypes were evaluated for tuber yield and its components as well as tuber dry matter (%) under six varied environments which are the combination between three years 2013/2014, 2014/2015 and 2015/2016 and two sowing seasons i.e.. fall and summer. The combined analysis of variance showed highly significant differences between genotypes, environments as well as GxE for all studied traits except for aerial stem No./plant which was insignificant, Phenotypic stability parameters revealed that potato genotypes Horaizon and Spunta were highly adapted to favorable environment. These results reflected the importance of environmental factors on the performance of genotype. According to phenotypic stability, the best cultivars were Horaizon and Caruso in most traits. For genotypic stability parameters, most cultivars considered stable in different studied traits. Horaizon, Hermus, Spunta and Inova were the most desired and stable for additive main effects and multiplicative interaction methods stability value (ASV) and regression coeffient (R2) in most traits. The ideal potato culturar was Carus for tuber number/plant, while Hermus was the ideal for average tuber weight, tuber yield/plant, tuber yield/fad., and tuber dry matter according to genotype+ genotype x environment.

Cancer is a big health problem with high morbidity and mortality and possess both economic and phsychological challenges. The aim of the present study is to evaluate methanolic (80%) ginger extract for their anticancer activity using two cancer cell lines: hepatocellular carcinoma cell line (HePG2) and breast carcinoma cell line (MCF7). The results showed that ginger methanolic (extract 80%) exhibited a pronounced cytotoxic effect and was found to possess a very potent inhibitory activities against hepatocellular carcinoma cell line (HePG2) and breast carcinoma cell line (MCF7).

The current study was conducted in order to assess nutritional knowledge and food behavior of osteoporosis among women in Sharkia Governorate, Egypt. Sources of information about osteoporosis and dietary intake of participants were also evaluated. This research was a descriptiveanalytical study. Data was collected using a questionnaire that was distributed to 300 women from Sharkia Governorate (150 healthy women and 150 patients diagnosed with osteoporosis). Results estimated that the most of healthy women (39.33%) were between 24 < 40 years old. While (38.70%) were between 40 - 55 years old in patients. The highest percentage of educational level for healthy women was 44% (secondary school), whereas, in patients was 43.3% (bachelor). The largest proportion of healthy women and patients had family income from 2000 < 4000 LE per month. 66% of healthy women hadn't relative suffering from osteoporosis. 48% of patients had fractions. Also, the results indicated that there were statistically significant differences in healthy women and patients and their age, education, job, marital status, history of osteoporosis in the family, menstruation, fractures, calcium and vitamin D supplements and physical exercises. Television appear to play the main role for osteoporosis information for respondents. The highest percentage of participants had average level of general knowledge, knowledge of rick factors and knowledge of protective factors about osteoporosis. The majority of healthy women and patients (68 and 71.3%), respectively, had average level about food behavior. There were statically significant differences between participants (healthy women and patients) and levels of knowledge about general knowledge, protective factors and total knowledge for osteoporosis. Most of respondents who had average level of knowledge have high education level. Healthy women (30.3%) and patients (45.5%) who had average level of knowledge have fractures and this association is statically significant. The results showed that most of participants who had average level of food behavior, were from average level of total knowledge about osteoporosis and this association is statically significant. The results illustrated that the highest percentage of patients took less than recommended dietary allowance of macronutrients and micronutrients which are important to prevent osteoporosis. It can be concluded that the most of subjects had average level of knowledge and food behavior about osteoporosis, while, low percentage had high level. Therefore, the recommendions are the use of television programs to raise awareness for all people about the prevention of osteoporosis, more effort from doctors and healthcare providers to inform patients about preventing and treating from osteoporosis and attention the government to this subject in its health policies and make more efforts to inform people especially women about osteoporosis.

Apple (Malus domestica) and mango (Mangifera indica L.) pulps were used as a prebiotic in the fortification of flavoured probiotic stirred yoghurt. Flavoured probiotic stirred yoghurt was made from cow’s milk supplemented with apple and mango pulps at levels of 5.0, 10.0 and 15%. Resultant stirred yoghurt of all treatments was stored at 5˚C for 15 days to study the physico-chemical, microbiological, organoleptic and colour properties (L*, a*, b*) of yoghurt samples during storage period. Addition of apple and mango pulps to cow’s milk increased acidity, total solids, but decreased total protein, total fat content and pH values of resultant flavoured probiotic stirred yoghurt. Also apple and mango pulps addition improved starter activity, increased total bacterial, bifidobacterial and lactobacilli bacterial counts of resultant flavoured probiotic stirred yoghurt. Colour characteristics (L*, a*, b*) are varied according to the kinds of fruit pulp used in yoghurt, which caused changes in colour of the yoghurt samples. These observations were associated with the level of mango and apple pulp addition. As a result of the organoleptic evaluations, 10% apple pulp yoghurt sample had the highest overall acceptability. Yoghurt with 10% fruit pulp, especially apple pulp could be recommended for large scale production of fruit probiotic yoghurt. [ABSTRACT FROM AUTHOR]

A total of 87 isolates of lactic acid bacteria (LAB) were isolated anaerobically from different food sources (yoghurt; Domiati cheese; fresh and fermented milk; mixed pickles and green olives), as well as human breast milk and infant stools. Only ten isolates showed high tolerance to pH 3.0 for three hours and therefore they were chosen for other studies. The selected isolates were identified based on physiological, biochemical and MALDI- TOF mass spectrometry identification. The most frequently observed genus was Lactobacillus (8 isolates) and one isolate seemed to be Enterococcus faecium and another isolate showed that it is Bifidobacterium bifidium. All of the tested species with a score value between 2.000 to 2.484 (100%) were correctly identified by MALDI -TOFMS to the genus and species levels. The majority of LAB species were tolerant to 0.3% bile salts for up to 4 hrs but L. fermentum was the most tolerant. Four species exhibited partial bile salt hydrolase activity. All of the species survived in 1 mg/ml pancreatin for 4 hrs. However, two of them showed 1/10 decrease in their numbers. Eight species were non haemolytic. Most of the tested species were resistant to penicillin (10 μg), ciprofloxacin (5 μg), gentamycin (10 μg) and streptomycin (10μg). However other species showed variable resistance against the ten tested antibiotics according to NCCLS. The cell free supernatant of L. acidophilus (IS9) showed the highest antimicrobial property against all the indicator pathogens tested specially Staphylococcus aureus and Klebsiella pneumoniae. Therefore, these 10 species were found, in vitro, to possess desirable properties in order to use as probiotic for human consumption. [ABSTRACT FROM AUTHOR]
