Problems solved by technology

The biggest problem is that although the undesired substances in the crude oil can be removed after refining and the product quality meets the relevant national standards for edible oil, it is difficult to retain the original fatty acid components of Torreya oil and the unique flavor, taste and smell of Torreya oil , and there is a risk of producing undesirable substances such as trans fatty acids

Abstract

The invention belongs to the technical field of oil refining, and discloses a production method of torreya grandis refined oil. The production method comprises a crude oil squeezing process and a refining process, wherein the refining process comprises the steps of degumming, deacidifying, color removal, winterization and the like. For the technical problem that no special production process is provided for producing the torreya grandis oil, the invention provides a special process for refining the torreya grandis oil. The refining technology provided by the invention is simple in refining procedures, definite in technological parameters and high in operability; the refined oil quality index conforms to the national edible oil standard, and fatty acid is kept in an original state; the refined oil reserves the intrinsic taste, smell and flavor of the torreya grandis oil; the refined oil is free from crystal, ribbon-shaped and granular crystals or trace mist-shaped precipitates in the storage process and good in commodity performance; and the refining process is high in oil yield and low in refining cost.

Description

technical field [0001] The invention relates to the technical field of oil refining, in particular to a production method of Torreya torreya refined oil. Background technique [0002] Torreya is a plant of the genus Torreya of the gymnosperm family Taxaceae (Taxaceae), and is an evergreen large tree. There are 3 species and 2 varieties of torreya in China: the first variety is Torrey agrandis Fort. ex Lindl., which is distributed in Zhejiang, Anhui, Fujian and Jiangxi; Torreya fargesii in Xinghe Emei area; the third variety is Torreya jackii in Zhejiang, Fujian and Jiangxi; the first of the two varieties is Torreya fargesii in Yunnan (and Burma) (Torreya fargesii var.yunnanensis), the second variety is Torreya grandis var.jiulongshanensis distributed in Suichang, Zhejiang. Torreya grandis (Torreya grandis Fort.var.Merrillii) is mainly eaten by artificial planting or harvesting of Torreya seeds. It is a variety (line) artificially bred from Torreya trees. It is propagated a...
