摘要:

为提高高温短时烘烤的中式香肠品质,本实验研究了添加量为肉质量0.00%、0.02%、0.04%、0.06%、0.08%和0.10%水平的脂肪酶(Palatase)对中式香肠脂质降解、脂肪氧化、挥发性风味物质和感官品质的影响。结果表明:添加脂肪酶能有效加速中式香肠中的脂肪降解和脂肪氧化,促进香肠中脂质来源的挥发性风味物质的生成。添加适量(0.06%)外源脂肪酶能使香肠香气显著增强,并且不影响香肠的其他感官品质;过量添加外源脂肪酶则会导致香肠过度氧化,影响感官品质。

Abstract:

The objective of this study was to improve the quality of Chinese sausage processed at high temperature by using
exogenous lipase. Effects of Palatase (a commercial lipase) on lipid hydrolysis, lipid oxidation, volatile components and
sensory attributes were studied at addition levels of 0.00%, 0.02%, 0.04%, 0.06%, 0.08% and 0.10%. The results showed
that palatase addition led to acceleration of lipid hydrolysis, lipid oxidation, and accumulation of lipid-derived volatile
components. Moderate addition of Palatase (0.06%) enhanced aroma without influencing the acceptability, while too much
addition could result in excessive oxidation with off-flavors.

Key words: Chinese sausage, lipase, free fatty acids, lipid oxidation, volatile components, sensory attributes
