This study was designed to elucidate the quantities of milk nutrients entrapped during cholesterol removal from milk by crosslinked -cyclodextrin (-CD, 0.4~1.2%, w/v) and to evaluate the amounts of the residual -CD in cholesterol-reduced milk treated by crosslinked -CD. The content of lactose in the control milk (without treatment by crosslinked -CD) was 4.86%, and the amounts of lactose entrapped by crosslinked -CD ranged from 0.00 to 0.03%. The total amounts of the entrapped short-chain free fatty acid (FFA) and free amino acid (FAA) ranged from 0.03 to 0.09 ppm and from 0.28 to , respectively. The amounts of the entrapped water-soluble vitamins (L-ascorbic acid, niacin, thiamine and riboflavin) ranged from 0.02 to 0.05 ppm, 0.01 to 0.06 ppm, 0.00 to 0.06 ppm and 0.01 to 0.06 ppm, respectively. The entrapped amounts of lactose, short-chain FFAs, FAAs and water-soluble vitamins were not remarkably affected by the concentrations of crosslinked -CD (0.4~1.2%, w/v). Only very small amounts of residual -CD in the cholesterol-removed milk were measured (1.22~3.00 ppm). Based on the data obtained from the present study, it was concluded that the amounts of entrapped nutrients were negligible during cholesterol removal from milk by crosslinked -CD, and only trace amounts of residual -CD were present in cholesterol-removed milk.
