摘  要:
采用常温处理,热水浸提处理,微波促溶处理和超声波辅助处理4种方法,处理经破碎含皮的深色葡萄皮渣液,促进葡萄皮中多酚类化合物的溶出,以提高葡萄汁的营养和功效价值。结果表明,微波促溶处理和超声波辅助处理均可以促进葡萄汁中活性成分多酚类物质的溶出。其中微波促溶处理后的葡萄汁中总酚含量为1 254.0 mg/L,花色苷含量为anthocyanins 2.180 mg/mL,超声波辅助处理后的葡萄汁中总酚含量为1 253.0mg/L,花色苷含量为2.110 mg/mL,但微波辅助处理时间短,是超声波的1/50,并且处理后的葡萄汁色泽好,褐变指数较小,综合效果明显优于超声波辅助处理。

摘  要:
Four extractions were used respectively,such as the normal temperature extraction(traditional hot water extraction method,microwave method and supersonic method to treat the broken residue of grape skin to promote polyphenols dissoluted and to improve the nutritional value and effectiveness of grape juice.The results show that:microwave method and supersonic method can promote the active ingredient polyphenols dissoluted in grape juice.After microwave treatment,the total phenol content in grape juice was 1 254.0 mg/L, anthocyanin content of anthocyanins was 2.180 mg/mL.After supersonic treatment,the total phenol content was 1 253.0 mg/L,anthocyanin content was 2.110 mg/mL in grape juice.However,microwave assistant processing time was short,which was 1/50 of supersonic processing time,And the color of grape juice is better,and browning index is smaller,the combined effect is better than supersonic assistant processing.
