Introduction of case-ready fresh meats to the marketplace has demonstrated a need to evaluate the benefits of this technology. The objectives of this study were to evaluate visual and chemical attributes of three different USDA quality grades (High Choice and above, Low Choice, Select) and three different muscles (semimembranosus, semitendinosus, and biceps femoris) of beef steaks encased in hi...

Most current research on Campylobacter has focused on preharvest or processing plant cross-contamination. Little is known about the effect of storage environment on the survival of Campylobacter on raw poultry. We evaluated the effects of modified storage atmosphere and freezing on the survival of naturally occurring Campylobacter on raw poultry. Broiler carcasses (n = 560) were collected as th...

abstract background: processes such as drying, sauce making, extracting and doping reduced nutritional value and unique sensory characteristics of pomegranate. on the other hand, the difficulty in peeling and removing the arils has limited its fresh consumption. for this reason, the “ready-to-eat” pomegranate may represent a possible option to implement fresh fruit consumption. in this study, t...

This study investigated the effects of modified atmosphere packaging (MAP), storage temperature, and use absorbent pads (PAD) on quality attributes Cape hake (Merluccius capensis) fish fillets. Fresh fillets were packaged under active-MA (40% CO2 + 30% O2 N2) or passive-MA (0.039% 20.95% 78% N2), with without PAD, stored at 0 °C, 4 8 °C (to mimic abuse temperature). The control fresh passive-MA...

Tománková J., Bořilová J., Steinhauserová I., Gallas L. (2012): Volatile organic compounds as biomarkers of the freshness of poultry meat packaged in a modified atmosphere. Czech J. Food Sci., 30: 395–403. The volatile organic compounds (VOCs) in the packing of chicken meat in a modified atmosphere was qualitatively and quantitatively evaluated. The total number of 72 samples of chicken hindqua...

PURPOSE To create in vitro a model to generate acidosis by CO2 bubbling "organ chambers", which would be useful for researchers that aim to study the effects of acid-base disturbs on the endothelium-dependent vascular reactivity. METHODS Eighteen male Wistar rats (230-280 g) were housed, before the experiments, under standard laboratory conditions (12h light/dark cycle at 21°C), with free acc...

The microflora was studied in beef stored in stainless steel containers kept under reduced pressure (20 to 30 kPa) in a modified atmosphere (70% N2 + 30% CO2 or pure CO2) at 3 to 4 degrees C and 0 to 1 degrees C at a headspace:meat volume ratio of 2:1. Samples were obtained at weekly intervals, 1 to 3 times. Total colony counts (TCC) for Pseudomonas spp. and Brochothrix thermosphacta were gener...
