Problems solved by technology

From a botanical point of view, in tea seeds, most of the tea seed oil and tea seed protein are integrated (oleoprotein complex - a compound of protein and oil), people use steaming, pressing, solvent extraction Complicated means such as forcibly separating them will not only waste manpower and material resources, but also have certain damage to the protein and other bioactive components (tea polyphenols, tocopherols, squalene, trace elements, etc.) in tea seeds; After the high-temperature refining of crude oil in the later stage, the natural bioactive components of tea seeds in the finished oil are running out

Abstract

The invention provides a tea seed oil protein compound and a preparation method thereof, and relates to the field of plant processing, in particular to the field of comprehensive processing and using of tea seed oil. The method comprises the following steps of soaking tea seeds in warm water and grinding into pulp after full imbibitions of the tea seeds; filtering pulp to obtain filtrate, standing the filtrate at room temperature, and precipitating to remove impurities to obtain upper-layer suspension liquid without impurities; carrying out hot suspension treatment on the upper-layer suspension liquid until a massive white top layer is formed on the top layer of the suspension liquid; and fishing white massive substances from the top layer of the suspension liquid after the suspension liquid is subjected to hot suspension treatment to obtain a tea seed oil protein compound crude product. The method is carried out at the low temperature below 55 DEG C, chemical additives are not required, and various nutritional ingredients of the tea seed oil protein compound are kept to a maximum extent; and the yield of the oil protein compound crude product produced by the method is high and is 32.2-38.1%, and by the purification method of the invention, the recovery rate of the oil protein compound crude oil is above 90%. The method is simple in technological flow, low in investment, low in cost and suitable to be popularized and used in mountainous areas or villages.

Description

technical field [0001] The invention relates to a vegetable oil protein compound and a preparation method thereof, in particular to an oil protein compound of tea seeds and a preparation method thereof. Background technique [0002] my country is the hometown of tea, and the resources of tea tree (Camelliasinensis) are very rich. The area of ​​tea picking gardens in the country is about 27 million mu, and the annual output of tea seeds (mature seeds of tea trees) is 560,000 tons. As a by-product of tea production, tea seeds contain a large amount of utilizable substances, among which the content of crude fat is 15%-35%, the content of starch is 18%-31%, the content of protein is 11-14%, and the content of tea saponin is 10%- 14%. Tea seed oil is a new type of edible oil produced from tea seeds. In addition to the use of general edible oil, tea seed oil also has health care functions because it is rich in unsaturated fatty acids, vitamin E, tea polyphenols and theophylline...
