可食性涂膜对熟肉制品保鲜作用的初步研究

PRIMARY STUDY OF EDIBLE COATINGS ON PRESERVATION OF COOKED MEAT

将两种可食性涂膜材料 ,分别与无毒抑菌剂联合使用 ,对熟肉制品进行保鲜处理 ,研究表明 ,经 60 %乙醇、 0 .5%乳酸和 0 .2 %醋酸复合抑菌剂浸泡 ,并以海藻酸钠涂膜包被 ,处理后的熟肉制品在 2 8℃保温 7天不腐败变质 ,细菌总数及大肠菌群均未检出 .

Preservation effects of 2 kinds of edible coatings combined with non toxic antiseptie germicides were studied. Showed that: After being treated with the combined antiseptic germicide of 60% ethanol, 0 5% lactic and 0 2% acetic acid, together with calcium alginate coating, the cooked meat was left unspolled at 28 ℃ for 7 days. The total bacterial number of the above treated cooked meat and E. coli of that were not detected.
