研究了毛豆的不同漂烫工艺,试找出最佳漂烫方式,通过对过氧化物酶失活率、蛋白质、抗坏血酸、叶绿素含量的变化及感官评定等来衡量微波处理、声热处理和热水漂烫对毛豆品质的影响。试验结果表明.声热处理1min能有效地钝化过氧化物酶,减少蛋白质、抗坏血酸和叶绿素的损失,同时提高了毛豆的感官品质。
The objective of this manuscript was to search a structured blanching approach to apply in quick-frozen green soy bean. The content of protein, ascorbic acid and total chlorophyll was determined after treated by microwaves, thermosonication and heat. Among of them, 1 min thermosonication treatment could efficiently reduced the POD activity, significant decreased the lost of protein, ascorbic acid and total chlorophyll.
