环糊精包合法制备低胆固醇猪油的工艺研究

Preparation of cholesterol reduced lard by treatment with β - cyclodextrin

对β-环糊精包合法制备低胆固醇猪油的工艺条件进行了研究。结合单因素试验和响应面分析确定优化的工艺参数为:β-环糊精用量3．6％(W／W),加水量38％(W／W),反应温度44 ℃,反应时间60 min。在该条件下猪油胆固醇含量从89．45 mg／100 g可降低至13．95 mg／100 g,脱除率达84．4％,结合β-环糊精回收方法可形成具有良好经济性的低胆固醇猪油生产工艺。

Operation condition in preparation of cholesterol reduced lard by treatment with β-cyclodextrin was investigated. Optimum conditions determined from single factor test and response surface analysis were as follows： concentrations of β- cyclodextfin and water were 3.6% （W/W） and 38% （W/W） respectively, reaction temperature 44 ℃, reaction time 60 min. Under optimum conditions, the chalesterol content decreased from 89.45 mg/100 g to 13.95 mg/100 g the remove rate of cholesterol reached 84.4%, this process showed economic advantage when combined with a recovery process of β- cyclodextrin.
