Abstract

The invention provides application and a preparation method of tea seed episperm bioactive extracts, relating to the technical field of comprehensive utilization of agricultural waste resources. The extracts extracted from the hulls of oil tea fruits and tea fruits comprise bioactive materials, such as saccharicterpenin, tea polyphenol and the like and have the advantages of high comprehensive performance, wide and special application, wide sources and low cost; the extracts can be used as feed additives and antioxidants or used as intermediate products to respectively obtain tea saponin, tea polyphenol or tea-seed polysaccharide applied to food and pharmaceuticals industry after separating and purifying treatment; in the preparation method, the hulls of the oil tea fruits and the tea fruits are soaked in a water-containing or anhydrous organic solvent and the extracts are directly extracted after dried in vacuum, and the preparation method has the characteristics of high extracting efficiency, high utilization efficiency of raw materials, simple and convenient producing process, low cost, wide raw material sources, wide application range, capability of turning waste into wealth, environment improvement, mass production, easy realization of industrialization, high economic benefit and the like.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of agricultural waste resources. Background technique [0002] Camellia oleifera is a unique oil crop in my country. It is widely planted in the vast hills and mountains in the south without occupying cultivated land. It is a major resource for forestry construction in my country. Camellia oil plays an important role in the balance of edible vegetable oil production in my country. One of the four healthy fats recommended by the organization. For every ton of camellia oil produced, there will be about three tons of tea seed shells (peel shells plus seed kernel shells). At this stage, the annual output of tea oil in my country is about 200,000 tons, and about 600,000 tons of tea seed shell waste will be generated. According to the development plan of the State Council on the camellia oleifera industry, during the "12th Five-Year Plan" period, the output of camellia oleifera will re...
