Physical low-temperature cold pressing process of tea seed oil

Abstract

The invention relates to a physical low-temperature cold pressing process of tea seed oil. The process comprises the following steps of: sorting collected tea seed fruits, discarding musty and shriveled tea seed fruits, removing mud and sundries, drying, breaking hulls, separating seeds and hulls, carrying out low-temperature storage after-ripening on the seeds, peeling, separating the seeds and skin, flaking, coldly pressing, multi-filtering, decolorizing with ozone, sterilizing and disinfecting to obtain the finished product of the tea seed oil. The process has simple, convenient and easy step, no loss of nutritional components in the tea seed oil in pressing and no secondary pollution and residues in the refining process, particularly ozone decolorization, and the tea seed oil maintains natural fragrance, presents clear and bright oil color and is better than first-class pressed tea seed oil of CB11765-2003.

Description

technical field [0001] The invention relates to a processing method of edible oil, in particular to a physical low-temperature cold pressing technology of tea seed oil. Background technique [0002] At present, the vegetable oils that people eat more include rapeseed oil, peanut oil, sunflower seed oil, walnut oil, corn oil and tea seed oil. The usual method of pressing tea seed oil is to dry and break the collected tea seeds and fruits, take out the tea seeds and dry them again, and process vegetable oil through basic processes such as flaking, steaming, pressing, leaching, and refining. The existing technological method of extracting oil from tea seeds has the disadvantage that the tea seeds will be steamed and fried, which will easily lose the nutrients in the oil and the fragrance of itself. The traditional refining process also requires vacuum drying, vacuum decolorization, high-temperature and high-vacuum deodorization of the extracted tea seed crude oil, and also cau...
