摘要:

研究芦笋速溶茶微波浸提工艺。以黄酮提取率为指标,采用响应面分析法对影响速溶茶品质的主要因素(微波功率、提取时间、液料比、浸提次数)进行优化,建立影响因素与响应值之间的函数关系。结果表明最佳工艺条件为:微波功率560W,液料比17:1(mL/g),时间32s,浸提次数1 次。在该工艺条件下,黄酮提取率为90.28%,速溶茶中黄酮含量为58.41mg/g 干基。表明速溶茶微波辅助提取的条件优化合理可行,可为生产提供依据。

Abstract:

In order to provide an Asparagus officinalis leaf infusion with higher content of flavonoids for asparagus instant tea production, key process conditions (i.e., microwave power, extraction duration and number, and ratio of liquid to material) for the microwave-assisted extraction of Asparagus officinalis leaves were optimized by response surface methodology. Under the following optimized extraction conditions: microwave power 560 W, ratio of liquid to material 17:1 (mL/g), extraction duration 32 s and extraction number 1, the extraction yield of flavonoids was 90.28%. The content of flavonoids in the asparagus instant tea produced was 58.41 mg/g (dry basis).

Key words: Asparagus officinalis, instant tea, microwave technology, flavonoids, respone surface methodology (RSM)
