摘要: 为了提高蛋液性能,降低生产成本,采用低温(0℃)和添加防腐剂来对液体蛋进行保鲜,并且对其乳化性,起泡性等性能进行了研究。结果表明:ε-聚赖氨酸盐酸盐为0.01%和Nisin为0.005%,添加量较小且能达到保鲜效果,蛋液能够保存13天,检测菌落总数低于百万;与巴氏杀菌蛋液相比,随着时间的延长,加入防腐剂的蛋液起泡性提高了10%,泡沫稳定性提高了9.8%,乳化性和乳化稳定性差异不大。巴氏杀菌蛋液的色度与新鲜蛋液的色度差异?E为9.8,差异非常显著,而加入防腐剂的蛋液与新鲜蛋液的色度差异?E为3.6,差异不是非常显著。因此,ε-聚赖氨酸盐酸盐和Nisin能够起到防腐的作用,并且在一些方面比巴氏杀菌蛋液更好。

Abstract: In order to improve the performance of liquid egg, reduce the cost of production, liquid eggs were preserved under low temperature (0℃) and by adding preservatives. Then emulsifying property, foaming property and other properties of liquid egg were studied. The results showed that using ε-polylysine hydrochloride and Nisin at the concentration of 0.01% and 0.005% could achieve good preservation effect, which could extend the shelf-life to 13 days with the total number of colonies detected less than one million. Compared with pasteurized liquid egg, foaming property of liquid egg added with preservatives increased by 10%, and foam stability increased by 9.8% with the extension of time. There were only slight differences in emulsifying property and emulsifying stability. The chromaticity difference ΔE of pasteurized liquid egg and fresh egg was 9.8, meaning that the difference was significant, while chromaticity difference ΔE of liquid egg added with preservatives and fresh egg was only 3.6, meaning that the difference was not obvious. Therefore, ε-polylysine hydrochloride and Nisin were corrosion resistant, and the effect was better than that of pasteurized liquid egg to some extent.
