摘要
研究了交联聚乙烯吡咯烷酮(PVPP)处理绿茶饮料的条件和效果。结果表明，在30～50℃、用4～5g/L交联度0.4％～0.6％的PVPP处理绿茶饮料，对茶多酚的去除率达到50％以上，明显改善了茶饮料的稳定性，延长了茶饮料的贮存期。研究还证明，PVPP与VC协同使用效果更佳。
In this paper,treatment on green tea with crosslinking poly Vinylpyrrolidone (PVPP)and treating conditions was studied .It proved that the tea adsorption ratio of tea polyphenol was up to over 50％when green tea was treated with PVPPunder 30～50℃,concentration 4～5g/L and crosslinking degree 0.4％～0.6％.Stability of tea beverage was improved greatly.Moreover ,PVPP could be used sgnergistically with VC.
