Raw samples of 14 muscles: Mm. biceps femoris (BF), quadriceps femoris (CF), diaphragm (DI), flexor digitorum (FD), gluteus medius (GM), infraspinatus (IE), longissimus lumborum (LL), longissimus thoracis (LT), psoas major (PM), pectoralis profundus (PP), semimembranosus (SM), semitendinosus (ST), sternomandibularis (STER) and triceps brachii (TB) from four(More)
Fresh beef steaks, either sprayed on the surface with a solution of rosemary and vitamin C or not sprayed, were packaged in 70%O(2+)20%CO(2+)10%N(2) and displayed at 1±1 °C without illumination or illuminated by a standard fluorescent lamp, a low-UV, colour-balanced lamp (Promolux®), or the fluorescent lamp with a UV filter. Metmyoglobin formation, lipid(More)
This research was aimed at evaluating the inhibition of oxidative changes of beef patties packaged in modified atmosphere (70% O(2)+20% CO(2)+10% N(2)) by natural antioxidants: ascorbic acid (500 ppm), taurine (50 mM), carnosine (50 mM), rosemary powder (1000 ppm) and their combinations with the first. Beef patties stored at 2±1°C for 20 days were evaluated(More)
The aim of this research was to reevaluate the inhibition of oxidative changes in beef patties packaged in modified atmosphere (70% O(2)+20% CO(2)+10% N(2)) by carnosine (50 mM). The need for reevaluation was because it had been postulated that hydrazine present as contaminant in commercial carnosine could contribute to the antioxidant activity. Beef(More)
The objective of this study was to evaluate the efficacy of propolis extract (PE) to reduce lipid oxidation and microbial growth on beef patties during refrigerated storage. Beef patties were manufactured by incorporating PE in 4 different treatments: (1) Control (no PE addition); (2) commercial propolis 1 (2% w/w; CP1); (3) commercial propolis 2 (2% w/w;(More)
