Preparation method of passion fruit double-skin milk

Abstract

The invention relates to a preparation method of passion fruit double-skin milk. The preparation method comprises the following steps of (1) pickling passion fruits with sugar: thoroughly cleaning mature passion fruits, draining the cleaned mature passion fruits, adding white granulated sugar, mixing the drained mature passion fruits and the white granulated sugar so as to obtain a mixture, and allowing the mixture to stand to juice the passion fruits; (2) making passion fruit syrup: putting the passion fruits with juice into a stainless steel pot after high-temperature sterilization, mashing and crushing the passion fruits in the stainless steel pot, boiling the crushed passion fruits with a strong fire, then slowly cooking the boiled passion fruits with a mild fire, and adding malt sugar and citric acid; (3) pretreating raw buffalo milk: performing protein detection and standardization pretreatment on raw buffalo milk; (4) performing mixing: taking egg white, stirring the egg white until foams are formed, mixing and stirring the foamed egg white, the passion fruit syrup and the raw buffalo milk until the mixture of the foamed egg white, the passion fruit syrup and the raw buffalo milk is in a homogeneous state, then filtering the homogeneous mixture, and performing filling so as to obtain raw material liquid; and (5) performing disinfection and cooling: heating the raw material liquid to raise the temperature to 95 DEG C, performing constant-temperature disinfection, and then naturally lowering the temperature to cool the obtained product. The passion fruit double-skin milk products obtained by the preparation method disclosed by the invention are superior in properties of color, state, various indexes and the like, simple in preparation method and low in production cost, and have the efficacies of promoting the health of cardiovascular systems, preventing cancer, resisting ageing, improving sight and the like.

Description

technical field [0001] The invention belongs to the technical field of dairy processing, and in particular relates to a preparation method of passion fruit double skin milk. Background technique [0002] Shuangpi Nai is a famous Cantonese-style dessert. Its production process seems to be very simple: first, boil the fresh milk and pour it into a bowl while it is hot. The heat will make the surface of the milk form a skin; Leave the creme at the bottom of the bowl, pour out the milk, add sugar and egg white and stir until foamy, then pour it back into the bowl with the creme just now, so that the creme at the bottom of the bowl floats: then put it on the fire and continue to steam, Take the pot and cool it in time, and new milk skin will be formed, which is double skin milk.
