Cholesterol Removal from Egg Yolk by β-cyclodextrin
摘要/Abstract
研究了不同条件下对蛋黄中胆固醇去除率和β-环状糊精(β-cyclodextrin,β-CD)残留率的影响.结果表明,蛋黄经20 MPa均质,添加质量分数为8%的β-CD,经35℃混合10 min,4 000r/min离心10 min,胆固醇的去除率能够达到85%,此时β-CD的残留率为14.3%.
Influence of the optimum conditions of the different factors on removal rate of cholesterol from egg yolk and the residue percent of β-cyclodextrin,the optimum process parameters in lab-scale were obtained.The optimized result showed that with lower additive of cyclodextrin(8 %),the higher removal rate of cholesterol was reached(85 %) without changing the nutritional values and the functional properties of egg yolk.When the homogeneous pressure was 20 MPa,10 minutes for mixing by mixture at 35 ℃,10 minutes for centrifuging at 4 000 r/min,the residue rate of β-cyclodextrin was 14.3 %.
