Istraživanje je provedeno kako bi se istražila mogućnost smanjenja natrija u krem siru, djelomičnom redukcijom odnosno zamjenom natrija pomoću kalijevih soli. Preliminarnim ispitivanjem odabrana su 4 načina soljenja: 100 % NaCl (kontrola), NaCl snižen na 65 % (T1), 35 % NaCl-a zamijenjeno KCl-om (T2), i mješavina soli Salut® na bazi KCl-a koja sadrži i tvari za prikrivanje stranih okusa (T3). Istraživanjem su ispitivana fizikalno-kemijska svojstva, boja, mazivost, prihvatljivost, kao i stupanj intenziteta specifičnih svojstava krem sira sa sniženim udjelom natrija. Snižavanje udjela natrija nije utjecalo na udio proteina, mliječne masti i vode, aktivitet vode, kiselost i boju krem sira (P>0,05). Međutim, redukcija natrija je značajno utjecala na mineralni sastav, mazivost i senzorska svojstva. Primjena mješavina soli na bazi kalija značajno povećava vrijednost omjera K:Na. Sirevi koji su sadržavali mješavinu soli Salut® od potrošača su dobili ocjene najbliže kontrolnom siru, u usporedbi s ostalim zamjenama. Ovo istraživanje pokazuje da je moguće smanjenje udjela natrija u krem siru za 35 % primjenom nutritivno vrijednih mješavina soli na bazi kalija, bez narušavanja prihvatljivosti proizvoda., The present study was performed to investigate the possibility of sodium reduction in cream cheese by partial reduction and substitution of sodium by potassium based salt. Four salt treatment were selected by preliminary study: 100 % NaCl (control), NaCl reduced to 65 % (T1), 35 % of NaCl substituted by KCl (T2), and KCl-based salt mixture Salut® which contains offflavours masking compound (T3). The study was evaluated physico-chemical attributes, colour, spreadability, sensory acceptance, as well as level of intensity of specific attributes of low-sodium cream cheese. Sodium reduction not influenced on the protein, fat and moisture content, water activity, acidity and the colour of cream cheese (P>0.05). However, sodium reduction significantly influenced to mineral composition, spreadability and sensory properties. The use of potassium salt substitutes significantly increased the value of K:Na ratio. Cheese containing commercial salt replacer Salut® had the closest hedonic score to control cheese compared to other replacers. The current research demonstrates that sodium content can be reduced by 35 % in cream cheese using a nutritionally valuable potassium-based salt mixture, without compromising the consumer acceptance.

The aim of this study was to use a predictive model to analyse the growth of a probiotic strain Bifidobacterium animalis subsp. lactis Bb-12 in cow’s, goat’s and soy milk. The Gompertz model was used, and the suitability of the model was estimated by the Schnute algorithm. Except for the analysis of Bifidobacterium animalis subsp. lactis Bb-12 growth, the Gompertz model was also used for the analysis of pH changes during the fermentation process. Experimental results, as well as the values of kinetic parameters obtained in this study, showed that the highest growth rate of Bifidobacterium animalis subsp. lactis Bb-12 was obtained in goat’s milk, and the lowest in soy milk. Contrary to the growth of Bifidobacterium animalis subsp. lactis Bb-12, pH decreased faster in soy milk than in cow’s milk. The highest rate of pH decrease was also observed in goat’s milk, which is in correspondence with results of various previous studies. The Gompertz model proved to be highly suitable for analysing the course and the fermentation kinetics in these three kinds of milk, and might be used to analyse the growth kinetics of other probiotic and starter cultures in milk., Cilj rada bio je upotrijebiti jedan od prediktivnih modela rasta bakterija za analizu rasta probiotičkog soja Bifidobacterium animalis subsp. lactis Bb-12 u kravljem, kozjem i sojinom mlijeku. Korišten je Gompertzov model, a prikladnost modela je procijenjena Schnuteovim algoritmom. Osim za analizu rasta Bifidobacterium animalis subsp. lactis Bb-12, Gompertzov model korišten je i za analizu kretanja pH vrijednosti tijekom fermentacije. Eksperimentalni rezultati, kao i vrijednosti kinetičkih parametara, dobiveni u ovom radu, pokazali su da je najveća brzina rasta Bifidobacterium animalis subsp. lactis Bb-12 bila u kozjem mlijeku, a najmanja u sojinom mlijeku. Suprotno u odnosu na rast Bifidobacterium animalis subsp. lactis Bb-12, pH vrijednost opadala je brže u sojinom mlijeku nego u kravljem. Najveći pad pH bio je također u kozjem mlijeku, što potvrđuju rezultati naših prethodnih studija kao i rezultati drugih autora. Gompertzov model pokazao se pogodnim za analizu tijeka i kinetike fermentacije u ove tri vrste mlijeka i može se koristiti za analizu kinetike rasta drugih probiotičkih i starter kultura u mlijeku.

The concentration of the minerals (Ca, Mg and P) and trace elements (Zn, Fe) were determined in goat and cow’s dairy products. The aim of this work was to determine the concentrations of mentioned minerals and trace elements in fermented dairy products made of goat milk, as well as in East Croatia traditional White Slice goat cheese. Obtained results show that goat milk and dairy products from goat milk had higher concentration of Mg and Fe than these of cow milk. Goat milk and dairy products from goat milk also had higher concentration of P, whereas the concentration of Ca was equally in goat and cow milk. However, significantly lower concentrations of Zn in goat milk and goat milk products were determined. Levels of analyzed major and trace minerals were higher in fermented dairy products and cheeses than in liquid milk. The levels of major and trace minerals in White Slice cheese were greater than those in fermented milk products. High content of phosphorus in White Slice goat cheese than in White Slice cow cheese was determined.

In general, lactobacilli are nonpathogenic part of the normal urogenital microflora and have been recognized as a barrier against colonization of unwanted (pathogen) microflora. The results of many in vitro studies suggest following mechanisms of probiotic lactobacilli action in urogenital tract: adhesion to urogenital cells, competition with pathogens for adhesive sites, production of biosurfactants, co-aggregation with pathogens, production of antimicrobial substances (organic acids, hydrogen peroxide and bacteriocins) and stimulation of immune system. From 80 different lactobacilli species isolated from human or animal intestinal and urogenital tract, only few lactobacilli strains possess optimal properties to be effective as probiotic therapeutics against infections in the urogenital tract. Combination of Lactobacillus rhamnosus GR-1 and Lactobacillus fermentum RC-14 was proposed as the best one for epithelial vaginal cells colonization and inhibition of uropathogens adhesion. The results of a number of clinical studies confirmed beneficial role of oral lactobacilli. However, the most of commercially available Lactobacillus strains, which are ordinary used in fermented dairy products, are seriously limited in protection of urogenital tract when they are ingested orally., Laktobacili su dio standardne nepatogene normalne urogenitalne mikroflore, koji djeluju kao barijera protiv kolonizacije nepoželjne (patogene) mikroflore. Prema rezultatima mnogih in vitro studija probiotički laktobacili u urogenitalnom traktu mogu djelovati putem sljedećih mehanizama: adhezija na stanice urogenitalnog trakta, natjecanje s patogenima za adhezivna mjesta, produkcija biosurfaktanata, koagregacija s patogenima, produkcija antimikrobnih supstancija (organske kiseline, vodikov peroksid i bakteriocini) i stimulacija imunološkog sustava. U urogenitalnom traktu samo nekoliko sojeva laktobacila, od 80 sojeva laktobacila koji su izolirani iz probavnog i urogenitalnog trakta, ima terapijska svojstva. U kolonizaciji epitelnih stanica vagine i sprječavanja adhezije patogena najuspješnijom se pokazala kombinacija bakterija Lactobacillus rhamnosus GR-1 i Lactobacillus fermentum RC-14. Rezultati niza kliničkih studija potvrdili su blagotvorni učinak oralnog unosa probiotičkih laktobacila. Međutim, najveći broj komercijalno dostupnih Lactobacillus sojeva, koji se uobičajeno koriste za fermentacije u mljekarskoj industriji, ukoliko se unesu oralno imaju limitirano zaštitno djelovanje u urogenitalnom traktu.

The aim of the study was to determine the influence of honey addition on fermentation of goat and cow milk with Bifidobacterium lactis Bb-12. Additionally, inhibitory potential of honey-sweetened fermented goat and cow milk against Listeria monocytogenes strain was examined. Two monofloral honey types, dark-colored chestnut and light-colored acacia honey were added. The basic hypothesis of this study was that addition of honey could have influence on the growth of Bifidobacterium lactis during the fermentation of goat and cow milk. Furthermore, higher inhibitory potential caused by honey addition against Listeria monocytogenes has been assumed. Compared to cow milk, higher acidity and CFU of Bifidobacterium lactis Bb-12 were noted in the fermented goat milk in all phases of the fermentation process. The results of this study show that both types of honey enhanced growth and acidity of the Bifidobacterium lactis Bb-12 in both milk types during fermentation. A disc assay has shown that development of growth inhibition zones depends on the type and concentration of honey, as well as on the milk type. The chestnut honey had generally higher inhibitory effect than acacia honey., U radu je ispitivan utjecaj dodatka meda na tijek fermentacije kozjega i kravljega mlijeka probiotičkom bakterijom Bifidobacterium lactis Bb- 12. Također, ispitivan je utjecaj medom zaslađenoga fermentiranoga kozjega i kravljeg mlijeka na inhibicijsko djelovanje rasta bakterije Listeria monocytogenes. Mlijeku su dodavane dvije vrste meda - tamna vrsta kestenova meda i svijetla vrsta bagremova meda. Osnovna pretpostavka u radu bila je da dodatak meda može utjecati na tijek fermentacije kozjega i kravljeg mlijeka, te na brzinu rasta Bifidobacterium lactis Bb-12 u mlijeku. Pretpostavljen je i jači inhibicijski učinak fermentiranog mlijeka na rast Listeria monocytogenes uzrokovan dodatkom meda mlijeku prije fermentacije. Rezultati ispitivanja pokazali su da obje vrste meda poboljšavaju rast i aktivnost Bifidobacterium lactis Bb-12 u obje vrste mlijeka tijekom fermentacije. Istovremeno, u kozjem je mlijeku tijekom cijelog razdoblja fermentacije zabilježena viša kiselost i veći broj stanica Bifidobacterium lactis Bb-12 nego u kravljem mlijeku. Testovi inhibicije rasta bakterije Listeria monocytogenes pokazali su da su veličine zona inhibicije ovisile o svim ispitivanim čimbenicima - vrsti mlijeka, vrsti dodanog meda, kao i o udjelu dodanog meda mlijeku prije fermentacije. Uzorci fermentiranog mlijeka s dodatkom kestenova meda jače su inhibirali rast bakterije Listeria monocytogenes nego uzorci s dodatkom bagremova meda.

Cilj rada bio je ispitati utjecaj fermentacije kozjeg i kravljeg mlijeka ABT- 2 kulturom na promjenu udjela pojedinačnih masnih kiselina u kozjem i kravljem mlijeku. Svrha rada bila je utvrditi povećanje udjela pojedinačnih kratko (SCFA - short chain fatty acids) i srednje (MCFA - middle chain fatty acids) lančanih masnih kiselina tijekom fermentacije kozjeg i kravljeg mlijeka. Hipoteza u radu bila je da veći udjeli SCFA i MCFA tijekom fermentacije ABT-2 kulturom nastaju u kozjem nego u kravljem mlijeku. Rezultati rada pokazali su da se fermentacijski procesi brže odvijaju u kozjem mlijeku u usporedbi s kravljim. Statistički značajno veći broj stanica probiotičkih bakterija Bifidobacterium spp. i Lactobacillus acidophilus La zabilježen je tijekom fermentacije kozjeg mlijeka, uz istodobno brže padanje pH vrijednosti kozjeg mlijeka u odnosu na kravlje. Uslijed fermentativne aktivnosti bifidobakterija iz ABT-2 kulture povećavao se udio SCFA i MCFA u obje vrste mlijeka. Međutim, značajno veći udio mjerenih SCFA i MCFA nastao je fermentacijom kozjeg mlijeka., In this paper, changes in composition and contents of each fatty acid during fermentation with ABT-2 culture were examined. The objective of this study was to determinate the increase of short (SCFA) and medium (MCFA) chain fatty acids in goat's and cow's milk during fermentation with ABT-2 culture. The hypothesis of this study was that higher contents of SCFA and MCFA are produced in goat's milk in comparison with cow's milk, during fermentation with ABT-2 culture. Obtained results have shown that fermentation process in goat's milk is faster than in cow's milk. The number of viable cells of probiotic bacteria Lactobacillus acidophilus La-5 and Bifidobacterium spp. was statistically greater in goat's milk than in cow's milk; consequently, pH value decreased more obviously in goat's milk than in cow's milk during whole fermentation process. Increase of SCFA and MCFA contents during fermentation was noted in both types of milk due to activity of bifidobacteria derived from ABT-2 culture. However, considerably higher amounts of examined SCFA and MCFA were produced in goat's milk than in cow's milk.

Cilj ispitivanja bio je utvrditi antagonistički utjecaj kozjeg i kravljeg mlijeka fermentiranog probiotičkom bakterijom Bifidobacterium longum Bb- 46 na rast uropatogenog kvasca Candida albicans. Hipoteza u ovom radu bila je da fermentirano kozje mlijeko ima moguće jače inhibicijsko djelovanje na rast Candida albicans u usporedbi s fermentiranim kravljim mlijekom. Povrh toga, praćene su korelacije između stupnja inhibicije i određenih parametara mliječno kisele fermentacije (broj stanica Bifidobacterium longum Bb-46 i pH vrijednost). Rezultati istraživanja pokazali su da fermentirano kozje mlijeko značajno jače inhibira rast Candida albicans u odnosu na fermentirano kravlje mlijeko (P<0,05). Nije utvrđena nikakva korelacija stupnja inhibicije rasta Candida albicans s pH vrijednosti fermentiranog mlijeka i brojem živih stanica Bifidobacterium longum Bb-46 u fermentiranom kozjem i kravljem mlijeku., The study was carried out to determine the antagonistic influence of goat and cow milk fermented with Bifidobacterium longum Bb-46 on uropathogenic Candida albicans strain. The hypothesis of this study was that fermented goat milk could have possible stronger inhibitory effect on the growth of uropathogenic yeast Candida albicans than fermented cow milk. The correlation between the inhibitory effect and the time of fermentation (number of viable Bifidobacterium longum Bb-46 cells and pH of fermented milk) was also determined. The obtained results have shown considerably higher inhibitory effect of fermented goat milk on the growth of Candida albicans compared with fermented cow milk. There was no significant correlation between number of Bifidobacterium longum Bb-46 cells in fermented and the inhibitory effect; as well as between changes in pH during fermentation and inhibitory effect of fermented goat or cow milk.
