Changes in bacterial flora of tripe samples, stored at 4°C in air, vacuum packaged or in a CO(2)-enriched atmosphere were studied. Aerobic plate counts showed a rapid increase in samples stored in air reaching a level of 1·6 × 10(9)/g from an initial level of 9·0 × 10(3)/g. The aerobic bacterial population inhibited in both vacuum packed and CO(2)-enriched atmosphere storage. The shelf lives of samples stored in air, under vacuum packaging or in gas mixtures, were 4, 8 and 9 days, respectively. Enterobacteriaceae and anaerobic counts tended to be higher under vacuum storage than in a CO(2)-enriched atmosphere. The numbers of lactic acid-producing bacteria were generally found to be lower under vacuum storage than in gas mixtures.
研究了牛肚样品在4°C空气中储存、真空包装或在富二氧化碳气氛中储存时细菌菌群的变化。需氧平板计数显示，空气中储存的样品迅速增加，从初始水平9.0×10³/g达到1.6×10⁹/g的水平。需氧细菌数量在真空包装和富二氧化碳气氛储存中均受到抑制。空气中储存、真空包装或气体混合物中储存的样品的货架期分别为4天、8天和9天。真空储存下肠杆菌科和厌氧菌计数往往高于富二氧化碳气氛。通常发现真空储存下产乳酸菌数量低于气体混合物中的数量。
