METHOD FOR PREPARATION OF TREATMENT-AND-PROPHYLACTIC FOOD ADDITIVE CONTAINING AQUEOUS DISPERSED FORM OF BETA-CAROTENE Russian patent published in 1998 - IPC

FIELD: food industry. SUBSTANCE: mixture of beta-carotene and pectin are subjected to mechanical activation either with full quantity of pectin introducing portionwise, or with its part. Ratio of beta-carotene and pectin is not less 1: 1. Dispersion is carried out in presence of pectin extract with beta-carotene preliminarily subjected to mechanical activation with pectin. Dispersion of beta-carotene is conducted for 0.5-1.5 h. Hydration is carried out either by drying in suspended layer of inert substances or by spraying method, or by coagulation by ethyl alcohol. Ratio is, respectively, 1: 2. Then coagulant is treated by alcohol in ratio 1:1. Dispersion is conducted in presence either of sugary filler, for example, saccharose; ratio of pectin and filler is 1:(0.6-10); or filler - maltodextrin; ratio of pectin and maltodextrin is 1:(1-6); or filler - beta-cyclodextrin; ratio of pectin and beta-cyclodextrin is 1:1. EFFECT: higher additive stability; usage of additive in product of long-term storage. 9 cl, 5 exp1
