Optimisation of cross‐linking β‐cyclodextrin and its recycling efficiency for cholesterol removal in milk and cream

Abstract

This study was carried out to investigate the optimum conditions of cross-linking b-cyclodextrin (b-CD) and recycling for cholesterol removal in milk and cream. The cross-linked b-CD was prepared with a 15% adipic acid solution, and the water solubility of the b-CD was measured for the optimum conditions based on mixing temperature, mixing time, cross-linking temperature, cross-linking reaction time and cooling time. In the results of this study, optimum conditions were 80°C mixing temperature, 2 h mixing time, 60°C crosslinking temperature, 24 h cross-linking reaction time and 48 h cooling time. After determining the optimum conditions, the recyclable yields of the cross-linked b-CD ranged from 90.01% to 55.17% in six recyclings and the percentage of cholesterol removal by 15% cross-linked b-CD was over 90% until eighth recycling. On the basis of the results, this study suggests that 15% adipic acid-added cross-linked b-CD maximised recyclable yield and that cholesterol removal was improved during recycling.

Physicochemical and antioxidative properties of Korean nanopowdered white ginseng

“…Further increase in temperature to 80°C showed slight increase in the solubility of ginseng powder. Increasing the temperature to 80°C can cause the glycosidic linkage to breakdown and loss of the structure, which leads to the greater leaching out of glucose (Zavareze & Dias, 2011;Lee et al, 2011). Swelling power of NPG was found to be lower than that of the PG (Fig.…”
