脂肪含量和脂肪氧化对肠衣色泽的影响

摘要

以肠衣色泽为评价指标,研究脂肪含量和脂肪氧化程度对肠衣色泽的影响.结果表明:脂肪含量对肠衣色泽有显著影响,乙醇处理后肠衣脂肪含量降低,肠衣△E值显著降低.肠衣色泽劣变与肠衣脂肪氧化相关性系数超过0.9,肠衣脂肪氧化是肠衣色泽劣变的重要因素.%In the present study,the effect of lipid content and oxidation on the color of casing was investigated.Result showed that lipid content has a significant impact on the color of casing.After alcohol treatment,lipid content of casing decreased while its △E decreased significantly.The correlation coefficients for the colour change and the lipid oxidation of casing over 0.9.The present study indicates that lipid oxidation is an important factor of the deterioration of casing's color.
