摘要:

以β- 环糊精为壁材制备β- 谷甾醇微胶囊,通过正交试验研究微胶囊化最佳工艺条件,比较不同抗氧化剂和微胶囊化前后甾醇对猪油的抗氧化作用。结果表明,β- 环糊精制备β- 谷甾醇微胶囊最佳工艺条件是加水量60mL、搅拌温度50℃、搅拌时间50min、β- 谷甾醇体积与β- 环糊精质量比为1:10(mL/g),在此条件下包埋率为87.98%。微胶囊β- 谷甾醇对猪油具有较强的抗氧化能力,其抗氧化效果优于未包埋的β- 谷甾醇和VE;随着甾醇添加量的增加,抗氧化能力增强。

Abstract:

β-Sitosterol has numerous biological functions such as antioxidation and so on. β-Cyclodextrin (β-CD) was taken as wall materia1 to prepare β-sitosterol microcapsules with better antioxidant effect. The preparation of β -sitosterol microcapsules was optimized using single factor and orthogonal array design methods, followed by a comparison of protective effect against lard oxidation with unmicroencapsulated β -sitosterol and vitamin E. The results showed that the optimal conditions for β-sitosterol microencapsulation were determined to be: water amount 60 mL, temperature 50 ℃, length of stirring time 50 min and ratio of 0.05 g/mL ethyl acetate solution of β -sitosterol to β -CD 1:10 (mL/g). Under these conditions, the embedding ratio of β-sitosterol was 87.98%. β-Sitosterol microcapsules could significantly protect lard from oxidation in a dosedependent way and was superior to unmicroencapsulated β-sitosterol and vitamin E.

Key words: β-sitosterol, β-cyclodextrin, microencapsulation, antioxidant effect
