FIELD: food industry.SUBSTANCE: invention relates to food industry, in particular to production of juice-containing beverage, and can be used at tinned food factories. Beverage contains following components, wt%: apple juice - 42.0-45.0, pectin extract from pulp of girasol tubers - 39.0 -42.0, sweetening substance - 1.0-2.0 and plum juice - 14.0-15.0. Plum juice is taken in ratio to apple juice of 1:3, and sweetening substance used is a mixture of fructose and citrose at a ratio of 1:0.001. Pectin extract from pulp of girasol tubers can be obtained by hydrolysis extraction of pulp of girasol tubers with a mixture of milk whey and citric acid at a ratio of 1:6 at pH 2.3-3.0 for 40-60 minutes at temperature 70-75 °C. Tubers before hydrolysis-extraction are subjected to treatment with electromagnetic field of extremely low frequency at frequency 29 Hz for 35-50 minutes.EFFECT: invention improves organoleptic properties and flavour properties of beverage, and preserves its stability during storage life and reduces calorie content.1 cl, 2 tbl, 3 ex |
