Abstract

The invention discloses an ice cream milk paste and a preparation method and a soft ice cream thereof. The ice cream milk paste comprises the following active ingredients in percentage by weight: 3-6% of milk fat, 2-3.5% of lactoprotein, 2.5-4.5% of lactose, 0.2-1.0% of yolk powder, 5-20% of sweetening agent, 0.05-0.5% of an emulsifying agent, and 0.05-0.6% of a stabilizer and water; the method comprises the following steps: (1) evenly mixing the yolk powder, sweetening agent and water, heating to 60-80DEG C, and then evenly mixing together with the emulsifying agent and the stabilizer to obtain a liquor A; (2) cooling to 30-63DEG C, then evenly mixing together with milk fat raw material, the lactoprotein raw material, the lactose raw material and water to obtain a liquor B, and controlling pH to be 6.5-6.8; and (3) performing scraper type ultrahigh-temperature instantaneous sterilization and sterile homogenization and cooling. The prepared ice cream milk paste is off-white color or faintly yellow, fine in mouth feeling, standout in flavor, and good in stability, and pipe blocking or pipe coking cannot be caused during preparation.

Description

technical field [0001] The invention relates to an ice cream milk slurry, a preparation method thereof and soft ice cream. Background technique [0002] Ice cream is a traditional frozen food with a delicate and smooth taste, and it is a favorite food for cooling down the summer heat. The earliest production of ice cream was made by adding milk to sugar and freezing it in the refrigerator. Later, it was produced on an industrialized assembly line. With the improvement of people's living standards and the change of the concept of quality of life, the demand for ice cream continues to increase, and the soft ice cream made on-site in various brand ice cream chain stores is more and more popular. The raw materials commonly used in ice cream are ice cream powder and ice cream milk slurry. Because ice cream powder is spray-dried at high temperature, the flavor and taste of the product will not be good. However, it is stored and transported at room temperature and has a long shelf...
