1. Utilization of zein-based coatings containing vegetable oils on the physicochemical characteristics of vacuum-packaged lamb meat
RESUMO: Durante a vida de prateleira da carne fresca podem ocorrer mudanças físico-químicas, microbiológicas e sensoriais indesejadas. Para evitar tais mudanças a combinação da embalagem tradicional à vácuo com revestimentos comestíveis é uma alternativa. O objetivo deste estudo foi avaliar o efeito do uso de diferentes revestimentos comestíveis

3. Qualidade de lagostas armazenadas em diferentes condições de temperatura e embalagem
Resumo A lagosta é uma espécie marinha de grande importância em muitos países. As mudanças bioquímicas e microbiológicas que ocorrem após a captura determinam sua qualidade e vida útil. Objetivou-se, neste trabalho, estudar o efeito da temperatura de armazenamento sob congelamento (-30 ºC, -80 ºC e -150 ºC), do tipo de embalagem (polietileno de b

4. Lipid oxidation in meat: mechanisms and protective factors – a review
Abstract Lipid oxidation in meats is a process whereby polyunsaturated fatty acid react with reactive oxygen species leading to a series of secondary reactions which in turn lead to degradation of lipids and development of oxidative rancidity. This process is one of the major factors responsible for the gradual reduction of sensory and nutritional quality o

5. Survival of Salmonella spp. in minced meat packaged under vacuum and modified atmosphere
Abstract The effect of different modified atmosphere packaging regimes on the behavior of Salmonella spp. on minced meat was studied. Minced meat was experimentally contaminated with a Salmonella spp. cocktail (S. Enteritidis, S. Typhimurium, S. Infantis and S. Arizonae), packaged under vacuum or modified atmosphere with initial headspaces containing 20%O2/5

6. Coating with chitosan film of sea bream (Sparus aurata) fillets: determining shelf life in refrigerator conditions
Abstract In the investigate, we objectived to assess the effect of coating with chitosan film on the shelf life. To this end, skinless sea bream fillets were separated as control group (C), vacuum packed (VP) and coated with chitosan film and vacuum packed (CF+VP). Samples of each group were periodically analyzed for microbiological [Total mesophilic aerobic

7. Retrogradation of heat-gelatinized rice grain in sealed packaging: investigation of moisture relocation
Abstract The aggregation of water molecules inside heat-gelatinized rice grain due to retrogradation of the grain was investigated by textural change and scanning electron microscopy (SEM) analysis of cooked grains after storage at 11 °C in a sealed package. Relaxation tests using a disc-type tip showed an increase in hardness (strength) of the cooked grain

8. Effects of carbon monoxide treatment before vacuum packaging on the physical parameters and consumer evaluations of raw beef
Abstract This study examined the color changes of packaged beef due to the effects of carbon monoxide exposure before vacuum packing and storage time, as well as consumers’ evaluations of that beef. In the experiment, 400 striploin steaks (M. longissimus dorsi) were vacuum packed or after 48 hours of exposure to different concentrations of CO (0.1%, 0.3%,

9. Effects of different packaging techniques on the microbiological and physicochemical properties of coated pumpkin slices
Abstract In this study the effects of zein film coating along with benzoic acid on the quality of sliced pumpkin samples, which were packaged with different techniques were investigated. The samples were allocated into different groups and were treated with different processes. Following processing, the samples were stored at +4 °C for twenty days. Physicoc

10. Chicken Meat Submitted to Gamma Radiation and Packed with or without Oxygen
The objective of this study was to evaluate the effects on gamma radiation levels on the physical and microbiological characteristics of chicken breast meat. A completely randomized experimental design in a 4x2x3 factorial arrangement was adopted. Treatments consisted of four radiation concentrations (0, 2, 4, or 8kGy), two package sealing methods (with or w

11. Oxidative stability of cereal bars made with fruit peels and baru nuts packaged in different types of packaging
Food industries have been concerned about managing the waste generated by their production processes in order to minimize environmental impacts and also about the development of formulations with different and innovative ingredients such as fruits from the Brazilian savanna. Seeking to meet the expectations of consumers who desire healthy and practical produ

12. Effect of heat treatment and packaging systems on the stability of fish sausage
The purpose of this study was to evaluate the physicochemical and microbiological stability of sausages produced from mechanically separated fish meat (MSM) obtained from Nile tilapia filleting residues. Different heat treatments (pasteurization or smoking) and packaging systems (conventional or vacuum) were used. The sausages were characterized for chemical
