Problems solved by technology

Due to the special flavor of raspberry itself, the processing time of raspberry is too long and the temperature is too high in the process of traditional technology, which leads to serious deterioration of the flavor and is not easy to be recognized by consumers. Raspberry processed products sold on the market so far are rarely seen.

Abstract

The invention discloses a raspberry juice microcapsule fermentation dairy product which is produced from the following raw materials by weight percent: 15-20 of raspberry, 40-50 of sodium alginate, 450-550 of fresh milk, 20-25 of cane sugar, 0.018-0.022 of chymosin and 0.05-0.15 of CaCl2. The product is produced according to the following steps of: A, production of raspberry juice; B, preparationof a sodium alginate solution; C, preparation of coagulating bath; D, granulation; E, solidification and drying; F, raw milk processing; G, sterilization; F, inoculation and fermentation; H, coagulumcutting; I, whey separation; J, stirring and mixing; and K, packing. According to the product, the nutrient and health-care functions of the raspberry and the fresh milk can be effectively combined and integrated into a whole, moreover, a microcapsule technology is adopted to embed the raspberry juice, the juice microcapsule with the controlled-release characteristic is produced, the discomfort mouthfeel can be eliminated, the sensitive functional composition of the product is protected, and the raspberry health-care effect is improved.

Description

technical field [0001] The invention relates to a special fermented dairy product and a preparation process thereof, in particular to a fermented dairy product and a method for preparing, processing and fermenting raspberry juice microcapsules. Background technique [0002] Raspberry ( Rubus idaeus L. ), also known as raspberry, tray, marling fruit, raspberry, etc., is a plant of the genus Rubus in the family Rosaceae, a perennial deciduous semi-shrub. Raspberries are rich in SOD, vitamin C, vitamin E, anthocyanins, ellagic acid and other special functional ingredients. Food and Agriculture Organization of the United Nations listed as "natural green food" and "healthy food". However, due to the high acid content of raspberry, the fresh flavor is not good, and its skin is extremely thin, the tissue is delicate, the structure is fragile and the respiration rate is high, resulting in post-harvest storage resistance, so it is very important to find a suitable processing route....
