| The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color,... |

| Abstract: This study was conducted to investigate the effect of passive evaporative cooler on storage behavior - that is visual appearance, physiological loss in weight (PLW), color development, firmness, total soluble solids (TSS) and pH level of hot water treated eggplant fruit (Solanum melongena L.). Fresh harvested fruits were treated with hot water at 45°C for 1 h. The highest percentage of PLW (2.39%) was the fruit stored at ambient temperature of 25°C for nine days whereas the lowest percentage of weight loss (2.27%) was the fruit stored inside the passive evaporative cooler. In all cases, the decreasing rate of lightness (L* value) and increasing rate of greenness (a* value) and yellowness (b* value) of the hot water treated fruits were almost... |

| ABSTRACT The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8%) as a replacer for soybean oil and eight replicates of two quails each were used. A total of 240 fresh eggs were used for quality analysis, and 400 eggs were stored at 23ºC over a period of 0, 7, 14, 21, and 28 days for analysis of shelf-life. Polynomial regression and ANOVA with repeated measurements and Tukey´s tests were used. Soybean acid oil linearly increased the intensity of red (a* = -5.26 + 0.14 x, R2 = 0.89, P = 0.01) and yellow (b* = 42.32 + 0.44 x, R2 = 0.88 P = 0.01). All other variables of egg quality... |

| The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12ºC for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for 72h under the non-isothermal conditions with temperature abuse (12ºC/4h). Date of the sensory evaluation showed a small reduction in product acceptance in this condition. The juice, in the recommended validity period (48h), presented losses of less than 20% of the initial ascorbic acid content regardless of the treatment. However, after this time, the degradation... |

| ABSTRACT Mathematical models are widely used to predict the shelf life of foods. Lactic acid bacteria (LAB), particularly Lactobacillus plantarum, Weissella viridescens and Lactobacillus sakei, are the main spoilage bacteria of refrigerated, vacuum-packed meat products, stored in modified atmosphere, and their growth determines the shelf life length of these products. The objective of this study was to model the growth of L. plantarum, W. viridescens and L. sakei under different isothermal cultivation conditions and establish secondary models to describe the effect of temperature on the growth parameters of these bacteria. The LAB growth was evaluated in culture medium at temperatures of 4, 8, 12, 16, 20 and 30 ºC. The fit of Baranyi and Roberts (BAR) and... |

| ABSTRACT Nidularium procerum and Nidularium innocentii (Bromeliaceae) were cultivated in vitro on media supplemented with different sources and levels of GA3 (gibberellic acid). These sources were the commercial powder (analytical degree) and fermented extract obtained by Fusarium moniliforme via solid state fermentation. The in vitro elongation and rooting of these plants were evaluated after 50 days of cultivation. The GA3 present in the fermented extract possess the same effect of purified GA3 (analytical degree) for the increase of the height of aerial part of shoots of N. innocentii, but not for the N. procerum being the GA3 fermented extract in a lesser degree. The GA3 fermented extract influences negatively the rooting in N. innocentii, while GA3... |

| Microbiological and chemical changes were evaluated in freshwater prawn stored under refrigeration at 0°C and 5°C during 10 days, with special emphasis on indole production as a chemical spoilage indicator. The total psychrotrophic and indole positive microflora were mainly mesophilic, with indole positive microorganisms being less than 10% of the total microflora after 10 days storage under refrigeration. Bacteria from Enterobacteriaceae and Vibrionaceae families prevailed among the isolated indole positive strains. The use of the Most Probable Number-MPN method, using tryptone broth as culture medium, was the most reliable approach for the quantitative evaluation of the indole positive microflora. The stored samples showed increases in pH, L-tryptophan... |

| Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest conditions on the final quality of mango. Considerably less attention has been paid to the influence of environmental factors on mango growth, quality traits, and postharvest behaviour. In this paper, we provide a review of studies on mango showing how environmental factors influence the accumulation of water, structural and non-structural dry matter in the fruit during... |

| ABSTRACT In Brazil, fish are sold in retail fresh or frozen, whole, or gutted. To increase consumption, convenient products with good sensory attributes should be offered. The objective of this study was to develop and characterize, through physicochemical, microbiologica, and sensory traits, a fresh sausage of tambaqui fish (Colossoma macropomum). Three formulations, with different percentages of fat (0, 4.5, and 9%) were developed. To determine shelf life, samples of the products were refrigerated at 4 ºC for 12 days and microbiological analyses were performed on days 0, 3, 7, and 12. Analyses of centesimal composition, shear force, cooking weight loss, and water-holding capacity were carried out. The shelf life of the fresh sausages was estimated at 7... |

| ABSTRACT Sweet bread is associated with smooth texture and high carbohydrate content, tasty and filling - quality that makes it preferred for snack. The key is in formulating raw material and other components. Commonly, sweet bread has short shelf life. Frozen dough could be the solution to this problem, and glucomannan addition during freezing process should be able to improve its physicochemical characteristics. This research aims to determine the effect of adding modified arrowroot (Maranta arundinacea L.) starch (MAS) as substitution, and glucomannan as frozen dough cryoprotectant toward sweet bread’s physicochemical. Randomized Complete Block Design Factorial (RCBD) was applied, and two factors were studied. The first factor was modified arrowroot... |

| ABSTRACT Yam, cassava, jackfruit seed and mango seed kernel have potential for the extraction and use as starch in the food industry of starch or for the formulation of biodegradable coatings. As a biodegradable coating, starch can be applied in fruits characterized by a fast maturation, such as mango, which requires technologies to increase its shelf life. The aim of this study was to characterize starch from four non-traditional sources and to evaluate their potential as coating for ‘Palmer’ mango fruit. Starches used were extracted from cassava, mango seed kernel, jackfruit seed, and yam, and had their physical, optical, and chemical properties characterized for later use as coatings of ‘Palmer’ mango fruit. Fruits were coated with 3% cassava starch,... |

| Abstract It is important that the methods and materials used for to lengthen the shelf-life of food are simple, inexpensive and safe. For these reasons, herbal additives like cumin oil (Nigella sativa L.) have been preferred recently. Thus, the present study focuses on the influence of black cumin oil on chemical, microbiological and sensory quality of fish (Barbus grypus) fillets during storage at 2 ± 1 °C. Acceptability scores for sensory quality of all described treatment groups decreased with storage time. Defined limits for mesophilic bacteria and Total volatile basic nitrogen (TVB-N) were reached after 21st days for the control group, after 24th days for with 0.2% black cumin oil treated group and after 28th days for with 0.4% and 0.6% black cumin... |

| This work is aimed at evaluating the physicochemical, physical, chromatic, microbiological, and sensorial stability of a non-dairy dessert elaborated with soy, guava juice, and oligofructose for 60 days at refrigerated storage as well as to estimate its shelf life time. The titrable acidity, pH, instrumental color, water activity, ascorbic acid, and physical stability were measured. Panelists (n = 50) from the campus community used a hedonic scale to assess the acceptance, purchase intent, creaminess, flavor, taste, acidity, color, and overall appearance of the dessert during 60 days. The data showed that the parameters differed significantly (p < 0.05) from the initial time, and they could be fitted in mathematical equations with coefficient of... |
