对贝类罐头商业无菌检验的探讨

对４００袋贝类罐头进行商业无菌检验，变质１６袋，其中黑变胀袋１０袋，黑变但真空良好４袋，有絮状物沉淀２袋。对所有袋进行接种培养，并测其ＰＨ值，胀袋，黑变，产生絮状物沉淀袋的ＰＨ值与同批未胀袋的ＰＨ值无显著性差异。

Studies on the Commercial Inspection of Shellfish Soft Cans Without Bacteria

soft cans are commercially inspected without bacteria. The results indicate that 16 cans is spoiled, for these, 10 cans are blackness and expansion, 4 cans are appearances of blackness and 2 cans are appearances of coagulation. The pH values of all cans were determined and the results show that the differences between the normal cans and spoiled cans after culture of bacteria are negligible . All the results indicate that it is not enough to determine the quality of cans only depending on whether the cans are expansion or not. Anthor suggests to increase contents of inspection which include value, microorganism tests and appearance of the food for determining the quality of the cans.
