Problems solved by technology

[0003] Because tea seeds often have a relatively high moisture content when harvested, and generally lack advanced drying equipment, the tea seed oil produced has a high acid value and deep color, making it difficult to decolorize the tea seed oil.
Generally, when tea seed oil is decolorized, the amount of bleaching clay added is 3-4%, and the cost is relatively high.

Embodiment Construction

[0017] see figure 1 , a decolorization method of tea seed oil, comprising the following steps:

[0018] A. Degumming and deacidification: Add phosphoric acid of 1‰ of the weight of tea seed crude oil to tea seed crude oil with an acid value of 3mgKOH / g and mix it with tea seed crude oil to make the phospholipids in the tea seed oil absorb water and swell to form glue Then add 16 Baume NaOH to the tea seed oil containing colloidal particles by 35kg / T, mix, and make NaOH and the free fatty acid in the tea seed oil carry out neutralization reaction to form soap particles, and then the gained tea seed oil containing Colloidal particles and soap grains Tea seed oil is centrifuged through a disc centrifuge to separate the tea seed oil from the colloidal particles and soap grains, and then add soft water equal to 10% of the weight of tea seed crude oil to the separated tea seed oil , and then use a centrifugal mixer to make it fully mixed, and then use a disc centrifuge to separate ...

Abstract

The invention discloses a method for decolorizing tea seed oil. The method comprises the following steps of: degumming, deacidifying, desolventizing, decolorizing, dewaxing and deodorizing. An auxiliary decolorizing process is adopted according to the characteristics of dark color and high decolorizing difficulty of the tea seed oil, and the tea seed oil is acidified before being decolorized, so that decolorizing efficiency is improved, the using amount of argil can be reduced by 1.5 to 2 percent, and the decolorizing cost of the tea seed oil is effectively reduced.

Description

technical field [0001] The invention relates to the field of deep processing of tea seed oil, in particular to a decolorization method of tea seed oil. Background technique [0002] Tea seed oil does not contain erucic acid, cholesterol, aflatoxin and other additives. Tested bottled tea seed oil: tea seed oil contains more than 90% unsaturated fatty acids, 80-83% oleic acid, 7-13% linoleic acid, and is rich in protein and vitamins A, B, D, and E etc., especially the rich linolenic acid it contains is necessary for the human body but cannot be synthesized. After testing, the content of oleic acid and linoleic acid in tea seed oil is higher than that in olive oil. [0003] Because tea seeds often have a relatively high moisture content when harvested, and generally lack advanced drying equipment, the tea seed oil produced has a high acid value and deep color, making it difficult to decolorize the tea seed oil. Generally, when tea seed oil is decolorized, the amount of bleac...
