Refining method of organic camellia oil rich in nutrition

Abstract

The invention discloses a refining method of organic camellia oil rich in nutrition, and relates to the technical field of organic camellia oil refining. The invention aims to solve the problems of high equipment investment and high product oil loss. The method specifically comprises the following steps: selecting camellia seeds which have completely filled seed kernels and are free of worm damage, mildew and peculiar smell; wrapping the camellia seeds with filter cloth at normal temperature; filtering out camellia seed crude oil by virtue of the action of gravity, pressure, vacuum or centrifugal force; and repeatedly filtering out the camellia seed crude oil for more than one time to enable the impurity content in the camellia seed crude oil to be less than 0.2wt%. Saturated salt solutionis used for degumming, and the problems of solvent residues, harm to human bodies and the like are solved. The coagulation of non-hydrophilic phospholipid can be accelerated by adding the salt solution, and the phospholipid can be rapidly removed through a sedimentation method. The edible salt is low in price and suitable for industrial production, the use of the edible salt in degumming is beneficial to reducing the difficulty of recovering oil from oil residues, and raw materials for preparing edible phospholipid can be obtained.

Description

technical field

[0001] The invention relates to the technical field of organic camellia oil refining, in particular to a nutrient-rich organic camellia oil refining method. Background technique

[0002] Camellia oil is rich in vitamin A, vitamin B, vitamin C, vitamin E and a variety of trace elements beneficial to the human body; however, to obtain high-grade tea seed oil, it is necessary to refine tea seed oil, the presence of impurities in crude oil, It not only affects the edible value and safe storage of oil, but also brings difficulties to deep processing, but the purpose of refining is not to remove all impurities in camellia oil, but to remove impurities that are harmful to food, storage, industrial production, etc. Remove; oil refining is a relatively complex and flexible work, must be based on the purpose of oil refining, taking into account technical conditions and economic benefits, choose the appropriate refining method in order to produce high-grade tea seed oil...

Embodiment 1

[0038] A nutrient-rich organic camellia oil refining method, comprising the following steps:

[0039] S1: Choose Camellia oleifera seeds with plump kernels, no moths, mildew and peculiar smell, wrap the camellia seeds with a filter cloth at room temperature, filter out the crude oil from the camellia seeds with the help of gravity, pressure, vacuum or centrifugal force, and filter the tea seeds The crude seed oil is repeatedly filtered more than once, so that the impurity content in the crude tea seed oil is less than 0.2wt%;

[0040] S2: Take 100 parts of camellia oil by weight, send it into the alkali refining pot and stir evenly, the stirring speed is 60-70r / min, the stirring temperature is 30-40°C, and add saturated saline solution for neutralization during the stirring process Reaction, after the reaction is finished, carry out static precipitation, and the precipitation time is 2 to 4 hours;

[0041] S3: Bring the camellia oil obtained in step S2 to 50°C-60°C, and at a ...
