Abstract

The invention discloses a refining treatment technology of camellia oil. The technology comprises addition of phosphoric acid for degumming, alkali refining with sodium hydroxide, washing with water at 80-95 DEG C, oil and water separation, vacuum drying, decolorization through combination of vacuum and a decolorizing agent, deodorization at 210-220 DEG C, cooling crystallization and dewaxing. The technology has the advantages as follows: the acid value is adjusted effectively and the storage performance and quality of the camellia oil are guaranteed; excessive loss of nutrients is avoided, the damage degree of vitamin E is reduced, and efficient decolorization and degreasing can be realized.

Description

technical field [0001] The invention relates to the technical field of camellia oil production, in particular to the refining treatment technology of camellia oil. Background technique [0002] Camellia oil contains a lot of unsaturated fatty acids and oleic acid, rich in protein and multivitamins, especially rich in linolenic acid which is necessary for the human body but cannot be synthesized. However, during the refining process of camellia oil, due to improper refining technology, harmful substances will be discarded and a large amount of nutrients will be lost at the same time, resulting in a reduction in the types or content of nutrients in camellia oil. Therefore, it is necessary to develop a kind of camellia oil refining treatment technology to make high-quality camellia oil. Contents of the invention [0003] The object of the present invention is to provide a kind of refining treatment technology of camellia oil. [0004] A refining treatment technology of came...
