Refining process for cold-pressed camellia oil at low temperature

Abstract

The invention discloses a refining process for cold-pressed camellia oil at low temperature. The process disclosed by the invention comprises the following steps: processing raw materials; cold-pressing to obtain oil; carrying out high-precision filtration; hydrating and degumming; deacidifying; decolorizing; deodorizing; and dewaxing. According to the process disclosed by the invention, the harmful ingredients (for example, benzopyrene, free fatty acid, colloid, trace heavy metals, residual soap, debris, aflatoxin and the like) existing in the camellia oil and generated in the production process, and a unique unfavorable smell of the camellia oil are effectively removed; various unique natural beneficial nutrients of the camellia oil can be preserved to the maximal extent after the camellia oil is refined; and no harmful substance is generated in the processing process.

Description

technical field

[0001] The invention relates to the technical field of camellia oil production, in particular to a refining process of low-temperature cold-pressed camellia oil. Background technique

[0002] Camellia oil, also known as camellia oil, is obtained from the seeds of the Camellia oleifera Abel tree. It is one of the oldest traditional woody edible vegetable oils in my country. Its fatty acid composition is very similar to that of olive oil. Known as "Oriental Olive Oil". Camellia oil also contains various active substances such as tea polysaccharides, camellia saponins, flavonoids, tea polyphenols, vitamins and phytosterols. Regular consumption can reduce cholesterol, increase high-density lipoprotein, reduce low-density lipoprotein, lower blood fat, and prevent heart disease. For cerebrovascular diseases, improving immunity, anti-radiation, scavenging free radicals, preventing tumors and other effects, the International Food and Agriculture Organization has list...
