复合酶处理对梗丝品质的影响

The Effects of Multi-enzymes Treatment on Quality of Cut Stem

为了研究复合酶对梗丝品质的影响,考察了不同复合酶质量浓度对梗丝细胞壁物质、常规化学成分、挥发性香气成分和感官质量的影响,优化了复合酶的施加工序。结果显示:①复合酶处理总体上有利于提高梗丝品质,其细胞壁物质、常规化学成分及挥发性香气成分含量均有所改善,梗丝、云烟(R)的感官质量也均有所提升,其中高质量浓度(C)复合酶的综合效果最好;②复合酶不同施加工序对梗丝的影响不同,其中加料前和加料后工序的总体效果较好,都优于对照样,加料中工序的效果较差,且比对照差。因此,复合酶处理可改善梗丝品质,且于加料前和加料后施加复合酶可提高梗丝品质。

In order to study the effects of multi-enzymes treatment on quality of cut stem, the influence of different concentrations of multi-enzymes to cut stem＇s cell wall substance, routine chemical components, volatile flavor components and sensory quality was investigated, and the multi-enzymes adding processes were optimized. The results showed that multi-enzymes treatment was beneficial to improve the quality of cut stem on the whole. The cell wall substances, routine chemical components and volatile flavor components of cut stern were improved with multi-enzymes treatment. And the sensory quality of cut stem and Yunyan （R） was all improved. According to the results, the highest concentration （C） had the best effect. The multi-enzymes in different treatment processes had different effects on cut stem, and the before casing process and the behind casing process had good effect to cut stem, both of which were better than the control. While the casing process had bad effect, and the sample was worse than the control. Therefore, multi-enzymes treatment could improve the quality of cut stem, and adding multi-enzymes in the before casing process and the behind casing process could enhance the quality of cut stem.
