摘要:
高聚体原花青素的抗氧化性能明显不如低聚体，而且不易被人体吸收。SO42-/TiO2固体酸催化剂，采用降解高聚体原花青素用紫外分光光度计和凝胶色谱仪进行分析，以平均聚合度和降解率指标对降解效果进行评价。结果表明，固体酸加入量0.05g，反应温度70℃，反应时间60min的反应条件下，高聚体的平均聚合度从5.95降为2.31，降解率达到61.18%。
Abstract:
Antioxidant performance of polymeric procyanidins was significantly less than oligomers, and not easily absorbed by the body. The research is devoted to the preparation of SO42- / TiO2 solid acid catalyst with excellent performance, and the solid acid is used to degrade procyanidins in lotus-shaped medium. Degradation of Polymeric Procyanidins was analyzed by UV spectrophotometer and gel chromatography. The degradation degree was evaluated by the average polymeric degree and degradation rate. Under the reaction conditions of 10 ml of the solution of proanthocyanidin as degradation raw material, when the addition of solid acid was 0.05g, the reaction temperature was 70 ℃ and the reaction time was 60min , the results showed that the average polymerization degree of the polymer decreased from 5.95 to 2.31 and the degradation rate can reach 61.18%
