FIELD: food industry. ^ SUBSTANCE: invention relates to food industry, namely to manufacturing of diabetic jelly foods. Inuline containing food product composition contains fruit raw material, sweetening agent, gelatine and water. Milk and vegetable extract from yacon clubs in the quantity of 10-14% of composition mass is used as sweetening agent. Yacon clubs are washed, minced till the size of 1-1.5 mm and dried to the end moisture of 6-7%. Extracting is carried out in two stages with constant agitation in vibratory agitary. Extragent is curd-whey ultrafiltrate. During the first stage physiologically valuable ingredients are extracted from yacon clubs using curb-whey ultrafiltrate. During the second stage extract is separated from the remaining pulp by centrifuging at rotation frequency of 6 thousand rpm during 20 min during the extracting period of 40-60 min at the temperature of 50-60C, extracting agent pH equal to 4-5 with the ratio of yacon clubs or pulp and curd-whey ultrafiltrate r=1:4-1:6. The extract with 20-22 wt % of dry matter is obtained, pulp is covered with curd-whey ultrafiltrate and after extracting the extract is separated from pulp by centrifuging and further extract with 18-20 wt % of dry matter is obtained. The extracts are blended, pasteurised at 72-74C, held during 10-20 sec. and cooled down to 2-6C. Prepared gelatine, fruit raw materials and water is added to the obtained extract and heated to the temperature of 80-85C, mixed, filled out in forms at temperature not exceeding 40C and left for gelation for 1-1.5 hours. ^ EFFECT: invention provides for quality and food product nutritious value increase, caloric content decrease and citric acid elimination from the recipe. ^ 2 tbl, 3 ex |
