摘要
随机抽检市售鲜鸡蛋每个蛋壳表所污染的杂菌，总数达１４２３．１万个．０．５％～１．０％过氧乙酸液对污染鸡蛋壳表杂菌的抑菌圈半径细菌为５．５～８．６ｍｍ，真菌为７．２～９．３ｍｍ．市售鲜鸡蛋贮存３个月期间每隔１５ｄ递减的鲜鸡蛋失重率平均值，聚乙烯醇涂膜法为１．４９％，不涂膜的对照为２．３６％，用聚乙烯醇涂膜法贮存保鲜的市售鲜鸡蛋，在自然气温为６．５～２３．６℃及空气相对湿度为４１．２％～９１％等自然温湿度条件下贮存的累计蛋黄完好率，贮存４５ｄ者为８６．７％，而不涂膜的对照为６４．３％；贮存９０ｄ者为６７．５％，而不涂膜的对照仅为４０％．每千个鸡蛋所用的聚乙烯醇成本为１．７０元（当时的市售价格）．
The mixed mushroom total of every commercial eggshell polluted is 1423.1×10￣4 as random sampling.By 0.5%～1.0% acetic acid peroxide controlling the mixed mushroom0polluting the eggshell, the controlling circle radius millimeters. Bacterium is 5.5～8.6,Fungus is7.2～9.3.During the commercial eggs stored 3 months,every 15 days, the dropping average valueof the losing weight rate, polyviny alcohoal coating is 1.49%, no-coating contrast is 2.36%. Thecommercial eggs are stored by polyviny alcohoal coating.when natural air temperature is 6.5～23.6℃ and air relative humidity is 41.2%～91%, the intact rate of yolk reaches to 86.7% whenthey are stored 45 days,and no-coating contrast is 64.3%;It reaches to 67.5%when stored 90davs.and no-coating contrast is only 40%. 1000 eggs used polyviny alcohool,its cost is 1.70 yuan(At that time selling price).
