Embodiment 1

[0032] A method for preparing egg custard, characterized in that it is prepared according to the following steps:

[0033] (1) Select fresh eggs, remove the shells to obtain whole egg liquid, stir the whole egg liquid at a speed of 150-200rpm, filter to obtain uniform whole egg liquid, and set aside;

[0034] (2) Add the same amount of pure water to the whole egg liquid described in step (1) to prepare a certain egg-water mixture, and add 0.05% papain and 0.003% flavor protease to the egg-water mixture in terms of mass percentage , the enzymolysis conditions are pH 6.5, temperature 55°C, hydrolysis for 1 hour, stirring at low speed during the enzymolysis process, controlling the hydrolyzed DH at 5, killing the enzyme, and obtaining a protein solution with a low degree of hydrolysis after pasteurization, for later use; papain The activity of the compound flavor protease is 5000U / g, and the activity of the compound flavor protease is 3000U / g;

[0035] (3) Add lactose, which acc...

Abstract

The invention relates to sweet egg paste and a preparation method thereof. The sweet egg paste is a novel sweet paste type product taking full eggs as raw materials. According to the method, restriction enzyme hydrolysis, beneficial bacterium fermentation and static ultrahigh-pressure technical means are creatively combined, so that the sweet egg paste type food is obtained; and the product has the light yellow color, has no eggy and bitter tastes, and has the advantages of fine and smooth texture, slightly-elastic taste, moderate hardness, good quality, sweet and mellow taste, long aftertaste, abundant nutrition and easiness of digestion and absorption. According to the sweet egg paste, the economic benefits of related enterprises are improved and the development of fine egg processing industries in China is accelerated.

Description

technical field [0001] The invention belongs to the technical field of food processing, and provides an egg custard and a preparation method thereof, and relates to a product processing technology of whole egg liquid, in particular to a comprehensive processing technology combining restriction enzyme hydrolysis, beneficial bacteria fermentation and static high pressure . Background technique [0002] Cheese, with very high nutritional value, is the only cheese product on the market. However, due to the per capita milk production in my country is far below the level of developed countries, the quality of raw milk is uneven, and the cheese production process is complex, the production cycle is long, and the price is high due to low yield. These problems have led to cheese products being recognized in the market. Low. Therefore, it is of great significance to develop new cheese substitutes. Eggs are one of the most commonly eaten foods for human beings. They come from a wide ...
