摘要: 以绿茶面条微观结构、面汤色差及茶多酚保留率为指标,通过单因素试验对绿茶粉目数、添加量及水添加量等因素进行面条制备工艺优化,并对其相关性进行探讨。结果表明,绿茶面条制备最优工艺条件为水添加量42 mL、绿茶粉目数80目、绿茶粉添加量2%,在此条件下,面筋结构未出现流体化现象,面条网络结构致密有序、连续性好,煮制后的面汤色差值最小(ΔE=5.89),茶多酚的保留率最高(72.73%)。不同制备条件对色差影响大小依次为绿茶粉目数<水添加量<绿茶粉添加量,对茶多酚的保留率影响大小依次为绿茶粉目数>绿茶粉添加量>水添加量。通过探究不同制备条件对绿茶面条品质的影响,以期为绿茶面条的制备及茶中有效成分保留率的研究提供一定的理论依据。

Abstract: Taking the microstructure of green tea noodles, the color difference of the noodle soup and the retention rate of tea polyphenols as indicators, the mesh number and added amount of green tea powder, water addition were optimized through single factor experiment, and their correlation were discussed. The results showed the optimal process conditions for green tea noodles were water addition 42 mL, the mesh number of green tea powder 80, the added amount of green tea powder 2%. Under this condition, no fluidiification was observed in the gluten structure, the network structure of noodles was dense,orderly and well continuous, the color difference of the noodle soup after cooking was the smallest (ΔE=5.89), and the retention rate of tea polyphenols was the highest (72.73%). The effect of different preparation conditions on color difference was: The mesh number of green tea powder<water addition<the added amount of green tea powder. The effect of different preparation conditions on the retention rate of tea polyphenols was:The mesh number of green tea powder> the added amount of green tea powder> water addition. By exploring the impact of different preparation conditions on the quality of green tea noodles, in order to provide some theoretical basis for the preparation of green tea noodles and the research of retention rate of effective ingredients in tea.

Key words: green tea noodles, preparation conditions, microstructure, color difference, tea polyphenol retention rate
