Problems solved by technology

[0003] The tea bran powder sold in the market is basically not instant soluble in cold water, and it is easy to form agglomerates when brewing, and the solubility and dispersibility are not ideal. A lot of inconvenience; on the other hand, the processed products have serious loss of original medicinal ingredients and nutritional ingredients, and contain less natural tea saponin, which can remove oil stains, wash dishes, plates, pots, vegetables, fruits, etc. weaker
At the same time, it is easy to mold and deteriorate, and it is difficult to store

Abstract

The invention discloses a preparation method of instant tea bran powder, comprising the following steps: shelling dry camellia seeds to obtain camellia nuts; putting camellia nuts into a twin-screw oil press to carry out low-temperature pressing, and crushing the obtained camellia bran blocks into particles; adding water and compound enzyme to carry out enzymatic hydrolysis, centrifuging, and carrying out enzyme deactivation treatment on the obtained paste; pre-freezing at the temperature of minus 20 DEG C to minus 35 DEG C for 5-8 h; freeze-frying by a vacuum freeze drier, controlling vacuum degree to be 0.08-0.12 MPa and temperature to be minus 50 DEG C to minus 60 DEG C, and drying for 10-12 h to obtain dried tea bran; crushing by a pulverizer to 150-200 meshes so as to obtain tea bran powder; and finally irradiation-sterilizing by an ultraviolet lamp, and carrying out vacuum sub-packaging to obtain the instant tea bran powder. By the steps of enzymatic hydrolysis, vacuum freeze-drying and ultraviolet sterilization, etc., medicinal components and nutritional ingredients of the tea bran are not destroyed, and the prepared tea bran powder can be quickly dissolved in cold water and is convenient to carry, easy to preserve and convenient to use.

Description

technical field [0001] The invention relates to the technical field of food and medicine, in particular to a preparation method of instant tea bran powder. Background technique [0002] Camellia oleifera (Camellia oleifera) is an evergreen small tree belonging to the family Theaceae, and is an excellent woody oil plant in the hilly areas of southern my country. my country is a big tea-producing country, and the planting area of ​​camellia oleifera alone reaches 4 million hectares 2 , is the country with the most varieties of Camellia oleifera, the widest distribution and the highest yield of Camellia oleifera seeds in the world. Tea bran is the slag left after camellia oil fruit is pressed. The main components are tea saponin content of 12-18%, protein content of about 12-15%, starch and sugar 30-50%, and fiber content of 10-12%. . Tea saponin is a natural non-ionic surfactant, which has good emulsifying, dispersing, foaming, moisturizing and other functions, and has anti...
