Studied were a total of 86 batches of Eskimo ice-cream and 101 batches of 'cream' ice-cream. It was found that 83.6 per cent of the Eskimo batches were of 0.1 coliform titers and higher, and 16.3 per cent - of 0.01 coliform titers. The total microbial contamination of 86 per cent of the batches reached 50000 g, while that of 13.9 per cent reached 50000 to 180000/g. The colititer with 98 per cent of the batches of 'cream' ice-cream was 0.1 and more 0.1, and with 1.98 per cent only was it 0.01, while the microbial count with 96 per cent of these batches was up to 50000/g, and with 3.9 per cent it was from 50000 to 118000/g. Studied was the quality of the products used to obtain the Eskimo icing. The total microbial content of the surface layer varied from 200 to 46000/g, dropping up to 100-2100/g at storage. The fresh cow sweet cream butter had a colititer above 0.1 and did not contain yeasts and moulds per 0.01/gram of produce. During production, transportation, and storing of the produced frosting the microbial count rose 7 times, on an average, and the colititer dropped from 0.1 up to 0.001. The icing (frosting) used contributed to the rise of the microbial amount from 1.5 to 3.5 times and to the drop of the colititer of the final Eskimo product.
共研究了86批爱斯基摩冰淇淋和101批“奶油”冰淇淋。结果发现,83.6%的爱斯基摩冰淇淋批次大肠菌群滴度为0.1及以上,16.3%的批次大肠菌群滴度为0.01。86%的批次总微生物污染量达到50000/g,而13.9%的批次总微生物污染量达到50000至180000/g。98%的“奶油”冰淇淋批次大肠菌群滴度为0.1及以上,只有1.98%的批次大肠菌群滴度为0.01,而96%的这些批次微生物计数高达50000/g,3.9%的批次微生物计数为50000至118000/g。对用于制作爱斯基摩糖霜的产品质量进行了研究。表层的总微生物含量在200至46000/g之间变化,储存时降至100至2100/g。新鲜的牛甜奶油黄油大肠菌群滴度高于0.1,每0.01克产品不含酵母和霉菌。在生产、运输和储存生产的糖霜过程中,微生物计数平均上升了7倍,大肠菌群滴度从0.1降至0.001。所使用的糖霜使最终爱斯基摩产品的微生物数量增加了1.5至3.5倍,并使大肠菌群滴度下降。
