苹果多酚大豆分离蛋白可食性膜的研制

利用超声波-微波协同法将苹果多酚和大豆分离蛋白制成了新型可食性膜,并对其制备条件进行了优化。试验结果表明:可食性膜成膜的最佳工艺条件为多酚添加量为0.4%,大豆分离蛋白添加量为6%,作用功率为400W,作用时间为10min。

Ultrasonic/microwave assisted treatment was used to make a new edible film of grape polyphenols and soy protein isolate , and tested on meat preservation performance. The results showed that the best film formation condition were： the mass concentration polyphenol was0.4%,the massconcentration SPI was 6%, ultrasonic power was 400W,and ultrasonic time was 10min.
