Modified-atmosphere storage under subatmospheric pressure and beef quality: I. Microbiological effects.
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...
متن کاملSurvival of Aspergillus flavus and Fusarium moniliforme in high-moisture corn stored under modified atmospheres.
Freshly harvested high-moisture corn with 29.4% moisture and corn remoistened to 19.6% moisture were inoculated with Aspergillus flavus Link ex Fr. and stored for 4 weeks at about 27 C in air (0.03% CO2, 21% O2, and 78% N2) and three modified atmospheres: (i) 99.7% N2 and 0.3% O2; (ii) 61.7% CO2, 8.7% O2, and 29.6% N2; and (iii) 13.5% CO2, 0.5% O2, and 84.8% N2. Kernel infections by A. flavus, ...
متن کاملMicrobiological quality of goat's milk obtained under different production systems.
In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive). A survey of dairy goat farms in and around Pretoria carried out by means of a questio...
متن کاملMicrobiological Quality and Shelf Life of Enzyme-peeled Fresh-cut Persimmon Slices Stored in High CO2 Atmospheres
The microbiological quality and shelf life of enzyme-peeled fresh-cut persimmon slices were evaluated during storage in a high CO2 controlled atmosphere (CA) and active modified atmosphere packaging (MAP) at 10 8C. Microbial counts of the enzymepeeled slices were lower in high CO2 atmospheres (10%, 15%, and 20%) than in air during CA storage for 6 days at 10 8C with the 20% CO2 atmosphere being...
متن کاملMicrobiological quality of carbonated and non-carbonated mineral water stored at different temperatures.
The microbiological quality of five brands of carbonated and non-carbonated mineral water sold in Poland was studied. The study was carried out on the survival of heterotrophic bacteria at 22 and 37 degrees C (pour plate technique) in the samples of mineral waters stored at 4 and 22 degrees C. The one hundred ten bottles (twenty two bottles of each of the five brands) of carbonated and uncarbon...
