摘要: 探讨了溶液的酸碱度、温度、时间和溶剂效应等对β-环糊精树脂(β-CDP)包结香兰素的影响,提出了最佳包结条件(pH3.0、温度20℃、时间1.5h、乙醇浓度<1%)。所拟定的条件直接用于树脂相紫外分光光度法测定食品中的香兰素含量,结果满意。回收率92.6~96.1%。

Abstract: The effects of acidic -- basic properties of solutions, temperature, time and solvents on β--cyclodextrins polymer (β-CDP) including vanillin were investigated. The optimum including conditions were advanced (pH, 3. 0; temperature, normal atmospheric temperature; time 1. 5h, ethanol concentration, <1% ).The conditions had been applied to direct ultraviolet spectrophotometric determination of vanillin in foodstuffs using β-- CDP resin with satisfactory results. Rate of recovery is 92. 6 - 96. 1%.
