Problems solved by technology

[0005] At present, most enterprises have poor tea processing technology, the quality of camellia oil is not high, and the utilization rate of camellia seed resources is not high
Existing camellia oil processing technology mainly contains: hot pressing method, cold pressing method and leaching method, but the shortcoming of these three kinds of processing technology is also very obvious, and shortcoming is as follows: High temperature will cause Maillard reaction between the amino acid in the tea seed and the reducing sugar, which will deepen the color of the tea oil. At the same time, under the action of high temperature and oxygen, the vitamin E and polyphenols in the oil will be oxidized, resulting in nutritional loss and increasing benzene. And (α) the content of harmful substances such as pyrene; (2) Although the cold pressing method makes the indicators such as color, fragrance, taste, nutrient element content and harmful substance content of camellia oil better than hot pressed camellia oil, its oil yield It is only half of the hot pressing method, which greatly increases the production cost; (3) the extraction of camellia oil by leaching method will have certain solvent residues, which will affect the purchase desire of green and healthy consumers
Several known traditional techniques for producing camellia oil are not complete enough, and there are also various shortcomings, so it is urgent to develop a new type of camellia oil and tea soap organic liquid preparation technology to change the existing camellia oil. The status quo of oil processing technology is not perfect, and improving the utilization rate of camellia seed resources

Abstract

The invention discloses a preparation method of camellia oil crude oil and tea soap organic liquid, belonging to the technical field of tea seed oil production. The preparation method of the camellia oil crude oil comprises the following steps: shelling, pulverizing, soaking, Grinding and filtering, fermenting the obtained filtrate and separating the fermented liquid, heating the obtained top layer suspension, and filtering to obtain the camellia oil crude oil; at the same time, the middle layer filtrate obtained by separating the fermented liquid is filtered to obtain tea soap organic The crude camellia oil prepared by the present invention has high quality, high yield of crude oil, does not need to add any additives in the whole process, and the obtained product is all natural and pollution-free; and the prepared crude camellia oil does not need to be dephosphorized or decolorized , deodorization and other refining processes, only need to carry out deacidification treatment; the tea soap organic liquid obtained by the present invention can be used for the development of related products such as bio-organic liquid sterilization liquid, and can also be used as the mother liquor in the production and fermentation process. Utilization of camellia seed resources.

Description
