摘要: 以收率和包合率为指标,采用饱和水溶液法制备核桃油-β-环糊精包合物,通过单因素和正交试验确定优化工艺条件,并考察产品氧化稳定性和水溶性。结果表明:最佳制备工艺条件为核桃油与β-环糊精质量比1:4、包合时间4.5h、包合温度65℃,此条件下包合率达81.6%、收率达61.6%;经紫外分光光度法检测,核桃油-β-环糊精已形成包合物,核桃油-β-环糊精包合物可明显提高核桃油的氧化稳定性和水溶性。

Abstract: Walnut oil was encapsulated with β-cyclodextrin by saturated water solution. Based on a comprehensive evaluation of inclusion complex yield and inclusion efficiency, the optimal inclusion conditions were determined by one-factor-at-a-time and orthogonal array design methods to be: ratio of walnut oil and β-CD 1:4 (g/g), inclusion time 4.5 h, and inclusion temperature 65 ℃, under which, the inclusion efficiency was 81.6% and the inclusion complex yield 61.6%. UV spectrometric determination demonstrated the successful inclusion of walnut oil. The inclusion complex was a white powder-like solid and its solubility increased with increasing temperature. The storage stability of walnut oil was improved significantly after inclusion.
