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。

Abstract:  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.
