Problems solved by technology

This patented method imitates the processing technology of olive oil, and eliminates the pressing and extraction process and chemical refining process, avoiding the residue of chemical substances and the loss of nutrients, but this method does not consider the two woody oils of camellia seed and olive fruit The difference between the picking and processing process, olive oil is pulp oil, generally must be controlled within 8 hours from picking to processing, at this time the free fatty acids and peroxidation products in the oil are extremely low, this process can be considered
Camellia oleifera grows mostly in low mountain and hilly areas. It usually takes dozens of days to complete from picking, transportation, drying, shelling to crushing, and the free fatty acids and fatty acid peroxidation products produced during this process cannot be removed. , it is difficult to guarantee the quality of the finished product

Embodiment 1

[0035] A kind of low-temperature cold-pressed camellia oil refining process, the steps are as follows:

[0036] (1) Raw material treatment: select mature camellia seeds (remove seeds with poor maturity, moldy seeds and abnormal shapes, etc.), remove impurities (separate and remove various impurities in raw materials with a vibrating sieve), and microwave dry until the moisture content is 3-5 %, sent to the shelling machine for shelling, the husk content of camellia oleifera seeds after shelling is about 4%, then crushed to 80-200 mesh, steamed at 90°C for 25 minutes;

[0037] (2) Oil extraction by cold pressing: the crushed material after heat conditioning is sent to the oil press to obtain crude oil, and the oil output temperature of the oil press is 80°C;

[0038] (3) High-precision filtration: Crude oil is filtered with a filter cloth at room temperature so that the impurity content in the crude oil is less than 0.2% to obtain primary camellia oil;

[0039] (4) Hydration deg...

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...
