Abstract |
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. |
