FIELD: nanotechnology.SUBSTANCE: dry topinambour extract is added to a gellan gum suspension in methanol containing 0.01 g of E472c drug as a surfactant, stirred at 1000 rpm, then methylethylketone is added. The resulting nanocapsule suspension is filtered, washed with methylethylketone and dried, while the weight ratio of gellan gum to the dry topinambour extract is 1:1, 3:1, 5:1 or 1:5.EFFECT: method ensures simplification and acceleration of the nanocapsules production process, reduction of losses during the nanocapsules production and can be used in the pharmaceutical and food industries.4 dwg, 5 ex
