葡萄皮渣的营养价值及综合利用

通过分析总结葡萄皮渣的营养价值及国内外的研究现状,加深对葡萄皮渣循环利用的了解,有助于葡萄皮渣的深入发展及广泛利用。葡萄皮渣包括葡萄皮、籽及果梗,含有丰富的蛋白质、维生素、多酚、酒石酸、膳食纤维、葡萄籽油等营养成分。国内对葡萄皮渣的利用程度不高,目前还主要集中在生物活性物质的提取上。生物活性物质尤其是多酚类物质具有明显的抗氧化作用,在医药保健、食品、化妆品、化工等行业都有广泛的应用。酿造季节大量皮渣堆积给环境带来的巨大压力成为目前急需解决的问题。积极推广葡萄皮渣的综合利用不仅可以保护环境,还可以创造巨大的经济效益。

Nutritional Value and Comprehensive Utilization of Grape Pomace

The paper aims to understand the recycling use of grape pomaceby analyzing the research status of its nutritional value and summarizing research progresses at home and abroad. The study will benefit the indepth and extensive use of grape pomace. Grape pomace includes skin, seed and stem, which contains rich protein, vitamins, polyphenols, tartaric acid, dietary fiber, grape seed oil and so on. The utilization degree of grape pomace in domestic is still not high and mainly focuses on the extraction of bioactive compounds. Bioactive compounds especially the polyphenols have obvious antioxidant activity, which are now widely used in medical care, food, cosmetic and chemical industry. The accumulation of grape pomace in brewing season is the problem that needs to be solved urgently. The promotion of comprehensive utilization could not only protect environment but also create huge economic benefits.
