摘要: 通过研究不同脂肪添加量(5%、10%、15%和20%)的香肠在发酵过程中脂质和蛋白质的氧化水平,并对发酵前后的挥发性化合物进行分析,最后对香肠进行感官评价。结果表明,随着脂肪添加量的增加,硫代巴比妥酸值显著增加,肌原纤维蛋白的羰基含量增加,总巯基含量降低(P<0.05),说明增加脂肪添加量会促进发酵香肠中脂肪和蛋白质的氧化;挥发性化合物分析可知,脂肪添加量较高的发酵香肠,因脂质自动氧化产生的醛、酮、酸、醇、酯和烷烃类化合物含量也相应增加(P<0.05);感官评价结果表明,脂肪添加量为15%的发酵香肠,其整体可接受性最佳(P<0.05)。

Abstract: The effect of addition of different amounts of fat (5%, 10%, 15% and 20%) on protein and lipid oxidation in fermented sausages was investigated in this study. Meanwhile, the volatile compounds were analyzed before and after fermentation for 15 days and sensory evaluation was performed. The results showed that the thiobarbituric acid reactive substances (TBARS) value and carbonyl content significantly increased with increasing added fat. In contrast, there was a significant decrease in total sulfhydryl content (P < 0.05), evidencing that lipid and protein oxidation in fermented sausages were enhanced with increasing fat addition. The higher contents of volatile compounds formed as a result of lipid oxidation, such as aldehydes, ketones, alcohols, acids, esters and hydrocarbons, were observed in fermented sausages with higher amounts of added fat (P < 0.05). Finally, the sensory evaluation results showed that fermented sausages with 15% fat addition had significantly higher acceptability scores than those with other addition levels (P < 0.05).
