Abstract

The invention discloses a preparation method of vacuum freeze-dried instant tomato-egg soup. The vacuum freeze-dried instant tomato-egg soup comprises tomatoes, eggs and other auxiliary soap materials. The preparation method comprises the following steps of blending tomatoes, eggs and other auxiliary soap materials according to a certain ratio, pouring the mixed materials into a tray with square grooves, and carrying out vacuum freeze-drying dehydration to obtain cooked square solids. The preparation method has the advantages that raw materials are pre-frozen by a slow-freezing technology for a long time (great than or equal to 12-14 hours) and are subjected to sublimation drying under low working pressure (less than or equal to 30Pa) at a low sublimation temperature (less than or equal to 40 DEG C) and because the raw materials are dried under freezing conditions, ice crystals sublimate fast so that sublimation drying time is shortened; and a high desorption temperature (great than or equal to 70 DEG C) is adopted so that desorption drying time and water content are reduced and product rehydration is improved and nutrients of tomato-egg soup are furthest retained. Therefore, the preparation method is suitable for large-scale application.

Description

technical field [0001] The invention belongs to the technical field of convenience food, in particular to a preparation method of vacuum freeze-dried instant tomato egg soup. Background technique [0002] With the improvement of people's quality of life, the improvement of diet structure, and the acceleration of people's life rhythm, people's demand for convenience food is increasing. After soaking in hot water or steaming for a short time [0003] The ready-to-eat instant tomato and egg soup becomes another instant food besides instant food. It is a brand-new, nutritious, healthy convenience food that is more in line with the eating habits of Chinese people. It has a huge market potential and broad development prospects. The drying methods for producing convenient instant food mainly include hot air drying, microwave drying, microwave hot air drying, and vacuum freeze drying. The study found that the convenience foods produced by the first three drying methods basically ...
