Cholesterol Removal from Lard with Crosslinked 棺-Cyclodextrin

The present study was carried out to determine the optimum conditions of different factors (ratio of lard to water, β-CD concentrations, mixing temperature, mixing time and mixing speed) on cholesterol reduction from lard by using crosslinked β-CD.Crosslinked β-CD was prepared with adipic acid.When the lard was treated under different conditions, the range of cholesterol removal was 91.2 to 93.0% with 5% crosslinked β-CD, which was not significantly different among treatments.In a recycling study, cholesterol removal with crosslinked β-CD in the first trial was 92.1%, which was similar to that with new crosslinked β-CD.In up to eight time trials, over 90% of cholesterol removal was found.The present study indicated that the optimum conditions for cholesterol removal using crosslinked β-CD were a 1:3 ratio of lard to water, 5% crosslinked β-CD concentration, 40°C mixing temperature, 1 h mixing time and 150 rpm mixing speed.In addition, crosslinked β-CD made by adipic acid resulted in an effective recycling efficiency.
