摘要: 从葡萄籽中提取有效成分低聚原花色素(OPC)。研究了提取产物的溶解性、紫外吸收光谱、热稳定性、光稳定性和抗氧化性。结果表明,低聚原花色素水溶性较好,最大吸收波长为278nm,当T≤60℃时,对热稳定,具有一定的耐光性。OPC对猪油具有较强的抗氧化作用,且存在剂量效应关系。相同添加量时,其抗氧化能力优于VC、VE;三者混合使用时,VC、VE对OPC的抗氧化性均具有协同增效作用。

Abstract: The solubility,UV spectrum,heat and light stability and antioxidation activity of oligomeric proanthocyanidins (OPC) extracted from grape seeds were studied.The results showed that OPC had good water solubility,light and thermal stability(T≤60℃)and tis λmax was 278nm.The antioxidation activity of OPC.Comparing the same amount addition of OPC,VC or VE into lard,OPC was superior to VC or VE in antioxidation.When a mixture of OPC,VC and VE was used,a remerkable synergistic antioxidation was obserced.

Key words: grape seeds, oligomeric proanthocyanidins, antioxidation
