Fermented tea powder as well as preparation method and application thereof

Abstract

The invention discloses fermented tea powder as well as a preparation method and application thereof. The preparation method comprises the following steps: crushing fresh tea branches, mixing corn flour with a zymophyte agent, uniformly spraying the mixture into the tea branches, spraying water into the mixture to keep a humidity at 40-60%, sealing, putting the mixture in a dark environment, and fermenting at 18-30 DEG C for 10-15 days to obtain a fermented tea material; and drying the fermented tea material at a temperature of 40-50 DEG C, and crushing the dried fermented tea material into fine powder to obtain the fermented tea powder. The fermented tea powder makes full use of discarded tea branches to ferment and prepare feed, turning waste into treasure. The preparation method is simple, easy to implement, and suitable for large-scale industrial production. The obtained fermented tea powder has increased crude protein and crude fat content, reduced crude fiber content, is easy todigest and absorb by animals, is rich in various nutrients such as tea polyphenols, is rich in nutrients, has a strong flavor, and has good palatability. The prepared feed is high in nutritional value, and has functions of enhancing animal immunity, enhancing disease resistance, improving meat quality and the like.

Description

technical field [0001] The invention relates to fermented tea powder and its preparation method and application, belonging to the field of tea resource processing and development. Background technique [0002] my country is a traditional tea country with high output value of tea resources, but its comprehensive utilization rate is not high. Most of the discarded low-grade tea leaves, old tea leaves or pruned branches after picking are not used, which causes a lot of waste of tea resources and also affects healthy development of the natural environment. [0003] Tea contains a variety of functional ingredients, mainly including tea polyphenols, alkaloids, proteins, amino acids, polysaccharides, saponins, vitamins and mineral elements, which can enhance the animal body's antioxidant capacity, antibacterial and disease resistance, lower blood fat, Lowering blood sugar, regulating animal immunity and other functions. The development and application of tea and its by-products as...

Problems solved by technology

However, the content of tea polyphenols and caffeine in tea is high, and the taste is bitter. If it is directly added to feed, the palatability is poor, which may lead to a decrease in feed intake of livestock and affect its growth.

In addition, the content of crude fiber in tea is high, and direct feeding is not conducive to the digestion and absorption of animals.

[0004] The Chinese Patent Gazette has published a patent application with the application number 201611081822.2 and the application name "A Functional Laying Hen Tea Feed and Its Preparation Method"; the technology described in this application is to find new usage channels for tea and increase research on the quality and quantity of eggs laid; in fact, after the tea leaves are picked, tea branches need to be pruned in order to improve the quality and yield of tea in the coming year; these cut branches and old tea leaves are currently discarded , a pity
