This study evaluated the current practices of selecting cold storage preservation solutions in Brazil and their impact on delayed graft function (DGF) incidence and 1-year outcomes in kidney transplant recipients. A retrospective cohort study was conducted, including 3,134 brain-dead deceased donor kidney transplants performed between 2014 and 2015 in 18 Brazilian centers. The most commonly used preservation solution was Euro-collins (EC, 55.4%), followed by Histidine-tryptophan-ketoglutarate (HTK, 30%) and Institut Georges Lopez (IGL-1, 14.6%). The incidence of DGF was 54.4%, with 11.7% of patients requiring dialysis for more than 14 days, indicating prolonged DGF. Upon adjusting for confounding variables, HTK demonstrated a significantly lower risk of DGF than EC (OR 0.7350.82500.926), as did IGL-1 (OR 0.6050.7120.837). Similar protective effects were observed for prolonged DGF when comparing HTK (OR 0.4780.5990.749) and IGL-1 (OR 0.4780.6810.749) against EC. No significant association was found between preservation solutions and 1-year death-censored graft survival. In conclusion, EC was the most frequently used cold storage perfusion solution, demonstrating a higher incidence and duration of DGF compared with HTK and IGL-1, but with no impact on 1-year graft survival.

Flower stems of the Heliconiaceae family are gaining more and more space in the Brazilian market of ornamental plants and further knowledge about quality, productivity, and postharvest management is necessary. The objective of the present study was to evaluate heliconiaceae cultivated in full sun in the central-west region of Brazil in terms of agronomic traits and to determine the postharvest durability of floral stems submitted to cold storage. Accessions of Heliconia bihai cultivar Caribea, H. bihai cultivar Iris Red, and H. rauliniana were evaluated. Quantitative and qualitative morphological characteristics, the total number of flower stems produced, and number of marketable stems were obtained. Postharvest longevity was tested in a cold chamber at 16 °C and 19 °C and at ambient temperature of 26 °C. Morphological characteristics such as the length, diameter and fresh mass of flower stems, inflorescence length, and postharvest durability of the inflorescences were the most affected. The most important variables were the quality of flower stems, productivity of marketable stems, and postharvest durability. The studied heliconias presented agronomic characters within the commercialization standards, highlighting H. bihai (Caribea) which presented the highest productivity. The best storage temperature for all accessions evaluated was 16 °C. [ABSTRACT FROM AUTHOR]

The best sensorial Brown Turkey figs for the fresh market are the ones harvested soft. However, at this maturity stage, they have a very short shelf life, from two to seven days, depending on environmental conditions, which make their marketing very difficult. This research's goal was to increase the shelf life of soft 'Roxo de Valinhos' figs, a 'Brown Turkey' plant material grown in Brazil, stored under refrigeration, by applying 1-methylcyclopropene (1- MCP), an ethylene inhibitor. Soft 'Roxo de Valinhos' figs were submitted to 1-MCP at 0; 0.5; 1.0 and 1.5 μg. L-1 for 24 h in airtight, under refrigeration at 4 ± 1 ºC. Subsequently, fruits were stored for up to 17 days at 4 ± 1 ºC. After removing from refrigerated conditions, fruits were kept for one day at room temperature (22 ºC), and then they were evaluated to determine their physical and chemical features. 1-MCP at 1.5 μg. L-1 was able to increase the soft figs shelf life to 12 days. [ABSTRACT FROM AUTHOR]

This study analyzed the effect of rootstocks G.213, M.9 and Marubakaido with M.9 interstem of 30 and 20 cm (MB/M.9-30cm and MB/M.9-20cm) on postharvest quality, mineral composition and functional properties of 'Maxi Gala' apples. The evaluations were performed using fruits from a commercial orchard in Vacaria, RS, Brazil. Fruits were stored for 135 and 147 days in the 2014/2015 and 2015/2016 seasons, respectively, and analyzed one day after harvest and after cold storage (1.0±0.2 °C) followed by seven days in ambient condition. The mineral composition of fruits showed small and inconsistent differences between rootstocks. The MB/M.9-20cm provided higher total antioxidant activity and levels of total phenolic compounds in fruit peel than MB/M.9-30cm. For 2014/2015 season, soluble solids content at harvest was higher in fruits from trees with G.213 rootstock, not differing only from MB/M.9-30cm. In the 2015/2016 season, G.213 and M.9 provided higher soluble solids content after storage than MB/M.9-30 cm and MB/M.9-20cm. G.213 rootstock anticipated fruit maturity compared to M.9 in 2014/2015 season. At harvest and after cold storage, other quality attributes of 'Maxi Gala' apples were similar between rootstocks G.213, M.9 and Maruba with M.9 interstem of 30 and 20cm. [ABSTRACT FROM AUTHOR]

The gray mold caused by Botrytis cinerea is the main concern for the postharvest conservation of table grapes worldwide, and the use of sulfur dioxide (SO2) is the most common practice for its control. The aim of this work was to assess the postharvest conservation of the hybrid table grape 'BRS Nubia' by using a new technology known as a field ultra-fast SO2-generating pad before packaging the grapes. The fruits were harvested in the 2021 season from a commercial vineyard located at Marialva, Parana, Brazil. The experiment was conducted in a completely randomized design, with 4 treatments and 4 replications, and each plot consisted of 10 bunches. The treatments included: (a) control; (b) field ultra-fast SO2-generating pad (FUFR) during the 4 h before packaging; (c) dual-release SO2-generating pad (DR) during cold storage; and (d) FUFR pad during the 4 h before packaging in combination with the DR pad during cold storage. The bunches were packaged in 0.5 kg plastic clamshells and placed in carton boxes with a capacity of 10 units each. The treatments were evaluated after 30 and 45 days in cold storage (1 ± 1 °C) by means of the incidence of gray mold, shattered berries, stem browning, bunch mass loss and bleaching. After 45 days, the boxes were removed from cold storage and kept without the pads and liners for 3 days at room temperature (22 ± 1 °C), and the incidence of gray mold, shattered berries and stem browning were assessed. The use of the FUFR pad before packaging and the DR pad during cold storage, combined or not, were efficient at controlling gray mold, keeping the incidence of the disease very low. Both pads were also efficient at preventing the mass loss of grapes, but the percentage of shattered berries was lower when the FUFR pad was used. This allowed grapes to arrive already sanitized to the packing house, and no additional SO2-generating pads were needed, representing savings in economic terms for packaging operations. The stem browning, the chemical properties, and the color attributes of berries were not influenced by any treatment. [ABSTRACT FROM AUTHOR]

In Brazil, the institutional food service sector is a booming market, but it is still possible to observe inappropriate work conditions in Food and Nutrition Units. The present study aimed to perform a survey on safety assessment and use of Personal Protective Equipment (PPE) by the employees of a private Hospital Food and Nutrition Unit, in the city of São Paulo. The survey was conducted among the employees for PPE verification (availability and conservation) as foreseen in the Good Practices Manual. The unit had all PPE provided in good conditions. It was observed that 83% of employees make the appropriate use of PPE. The areas or activities that showed different degrees of inadequacy, where one or more employees did not use PPE, were cold rooms and cold storage, handling knives, cleaning of exhaust hoods, preparation of coffee, meat cutting, washing pots, usage of food processor, bread slicing and use of the fryer. Despite the frequency of usability observed (83%), continuous training and motivating, as well as the systematic control of the correct use of PPE, are necessary in order to ensure the safety of the employees.

This study evaluates a bio-based laser-perforated and recyclable SO 2 -generating liners, alone or in combination with ultra-fast SO 2 -generating before packaging, to extend the shelf life of 'Benitaka' table grapes (Vitis vinifera L.). Grape bunches were harvested from a commercial vineyard in Parana, southern Brazil, in 2020 and 2021, and packaged in clamshells organized in cardboard boxes (10 clamshells per box). Boxes were sealed with liners and were stored at 1.0 ± 1 °C and at 70–80% relative humidity. The presence of gray mold was assessed 30 d and 45 d after cold storage, and after 3 additional days at room temperature (22 ± 1 °C); bunch weight loss, stem browning, shattered berries, and bleaching were assessed. Bio-based and SO 2 -generating liners, in combination with ultra-fast SO 2 -generating pads applied before packaging 'Benitaka' table grapes, were effective in controlling the incidence of gray mold at 45 d of cold storage (< 0.4%) and at 3 d of room temperature (< 0.8%); this extended the shelf life of grapes, with low weight loss, fewer shattered berries, and the maintenance of stem freshness. The bio-based liner alone does not control gray mold effectively, but it has no adverse effect on the physicochemical qualities of 'Benitaka' grapes and is an eco-friendly packaging material. Using compostable bio-based or recyclable SO 2 -generating perforated plastic liners to control gray mold and other postharvest diseases may promote the near future use of sustainable materials in the food industry. • Bio-based liners helps to extend the cold preservation of table grapes. • Bio-based liner in combination with ultra-fast SO2-emitter pad is highly effective. • SO2-generating plastic liners alone have a moderate performance. • Bio-based liner alone does not effectively control gray mold.

Abstract: Storage of goat milk production in cold temperatures is a current Brazilian legislation request, however there is no specification of a limit period for this. The present work aimed to characterize the microbiological characteristics of raw goat milk produced in a specific region of Brazil, as well as the influence of the storage system and period on its quality. Sixty-one samples from 12 goat farms were collected and subjected to analysis to enumerate hygiene indicator microorganisms, psychrotrophics and proteolytic psychrotrophics. The obtained counts were described and compared considering the system and period of storage (ANOVA, Tukey). Despite presenting low counts of mesophiles, the samples presented high counts of other groups and a relevant presence of proteolytics. Samples collected from bulk tanks presented higher counts of mesophiles and psychrotrophics when compared to immersion tanks and freezers (p <0.05). When stored for a period of 48h or longer, the counts of mesophiles, coliforms, Escherichia coli and psychrotrophics were also significantly higher when compared to a storage period of 24h or less (p <0.05). The results indicate specific problems in goat milk production in the studied area and the need of establishing a period limit for raw goat milk collection in Brazil. [Copyright &y& Elsevier]
