摘要
采用壳聚糖作载体,1,6-己撑二异氰酸酯作交联剂,通过共价键固载β-环糊精。在吸附时间为120min,蛋黄被稀释25倍时,蛋黄中胆固醇脱除率达90.8%。β-环糊精/壳聚糖具有较好的重复使用性能,在重复使用5次后,胆固醇脱除率由90.8%下降至81.3%,仅降低了10.5%。测定结果表明,降低胆固醇含量后,鸡蛋的营养价值和性质没有发生明显的变化。
Immobilization of β-cyclodextrin to chitosan was completed（Ch-BCD） by covalent binding using 1,6-hexamethylene diisocyanate （HMDI） as cross-linking agent. 90.8% of cholesterol could be removed after 120 min adsorption and yolk has been diluted to 25 fold with water.This study used the Ch-BCD for the cholesterol adsorption from yolk. The Ch-BCD possesses good recycle performance.Cholesterol removal change was within the small range of 91.6% to 81.3%, which descended only 10.5% after 5 reuses. The results showed that there was no evident change of nutritional values and property after removing cholesterol from egg yolk.
