Optimization of β-Cyclodextrin Recycling Process for Cholesterol Removal in Cream
H. S. Kwak, H. M. Suh, J. Ahn, H. J. Kwon
This study was designed to find optimum conditions of four different factors (ratio of solvent to cholesterol-棺-cyclodextrin complex, mixing speed, mixing temperature, and mixing time) for cholesterol dissociation in cream. Using the ratio of 6 to 1 (solvent to the complex) showed the highest cholesterol dissociation rate (82.50%) when mixed at 100 rpm at 50째C for 1 h. Mixing speed did not significantly affect the cholesterol dissociation. Also, mixing time appeared to be insignificant. The optimum mixing temperature was 50째C and mixing at 40째C resulted in a significantly lower rate, compared with that at 50째C. In a subsequent experiment, using recycled 棺-cyclodextrin only showed 75.07% of cholesterol removal in cream, while the mixture of recycled to unused 棺-CD with the ratio of 6 to 4 increased cholesterol removal to 95.59%, which is highly close to that of 100% unused 棺-CD.
