摘要:
研究高压静电场预处理对黄豆芽生物成分的影响和不同电场处理条件下黄豆芽组织内抗坏血酸、可溶性蛋白质和总黄酮含量的变化.结果表明,经电场处理过的黄豆芽,3种生物成分与对照组相比均得到显著提高,不同处理条件对不同生物成分产生的生物学效应不尽相同.当电场强度为3~5 kV/cm、处理时间为15 min时,生物学效应最为明显.这表明电场预处理可以提高黄豆芽中抗坏血酸、可溶性蛋白质和总黄酮的含量.

Abstract:
Effects of high-voltage electrostatic field pretreatment of soybean on biological ingredient of soybean sprouts were studied. The results showed that electric field pretreatment could increase the content of biological ingredient of soybean sprouts including vitamin C, soluble protein and total flavanone during soybean germination. Different processes and conditions have different biological effect on different biological ingredient. The best effect was obtained when the intensity of electric field is from 3kV/cm to 5kV/cm and the processing time is about 15 minutes.
