Embodiment 1

[0050] 1. Oil residue separation

[0051] With the help of gravity, pressure, vacuum or centrifugal force, filter cloth is used at normal temperature to obtain tea seed crude oil with impurity content less than 0.2 wt%. Impurities include free fatty acids, colloids, trace heavy metals, residual soap, residual debris, aflatoxin, etc.

[0052] 2. Degumming

[0053] Get 100 kg of tea seed crude oil with impurity content less than 0.2wt% by weight, add 5 kg of warm water at 40°C to the tea seed crude oil, stir for 10 minutes, and let stand for 2 hours. The impurities and water in the lower layer were removed by sedimentation separation.

[0054] 3. Deacidification

[0055] When the tea seed crude oil after the degumming treatment was heated to 40° C., 2 kilograms of sodium hydroxide solution with a concentration of 12 wt % was added and stirred for 15 minutes. Then add 10 kg of water at 70° C., let stand for 8 hours, and remove water and soapstock by sedimentation and separati...

Impurities include free fatty acids, colloids, trace heavy metals, residual soap, residual debris, aflatoxin, etc.

[0065] 2. Degumming

[0066] Get 110 kg of tea seed crude oil with impurity content less than 0.2wt% by weight, add 10 kg of warm water at 30°C to the tea seed crude oil, stir for 15 minutes, and let stand for 4 hours. The impurities and water in the lower layer were removed by sedimentation separation.

[0067] 3. Deacidification

[0068] When the tea seed crude oil after the degumming treatment was heated to 50° C., 3 kilograms of sodium hydroxide solution with a concentration of 10 wt % was added and stirred for 20 minutes. Then add 15 kilograms of water at 60° C., let stand for 4 hours, and remove water and soapstock by sedimentation and ...

[0076] 1. Oil residue separation

[0077] With the help of gravity, pressure, vacuum or centrifugal force, filter cloth is used at normal temperature to obtain tea seed crude oil with impurity content less than 0.2 wt%. Impurities include free fatty acids, colloids, trace heavy metals, residual soap, residual debris, aflatoxin, etc.

[0078] 2. Degumming

[0079] Get 90 kg of tea seed crude oil with impurity content less than 0.2wt% by weight, add 5 kg of warm water at 35°C to the tea seed crude oil, stir for 15 minutes, and let stand for 3 hours. The impurities and water in the lower layer were removed by sedimentation separation.

[0080] 3. Deacidification

[0081] When the tea seed crude oil after the degumming treatment was heated to 42° C., 2 kg of 15 wt % sodium hydroxide solution was added and stirred for 18 minutes. Then add 10 kilograms of water at 60° C., let stand for 5 hours, and remove water and soapstock by sedimentation and separation. The acid value after...

Abstract

The invention relates to a refining method for edible oil and fat, in particular to a method for refining camellia oil with raw tea seed oil, and provides a refining method for the camellia oil with high nutrient content in order to solve the problems such as over nutrient loss of the camellia oil and the like due to over high temperature in the prior art. The method mainly comprises the following steps of: preparing raw oil at the normal temperature; adding warm water into the raw oil and removing the lower impurity and water by sedimentation separation; adding sodium hydroxide solution intothe oil and removing water and nigre by the sedimentation separation; heating the raw tea seed oil to the temperature of between 80 and 90 DEG C, adding 1 to 3 parts of active floridin into the oil, cooling the mixture under the pressure of -0.1 to -0.095MPa to the temperature of between 68 and 72 DEG C in 15 to 20 minutes and filtering the mixture with cotton cloth; distilling the mixture at thetemperature of between 140 and 150 DEG C and the vacuum degree of between 200 and 260Pa to obtain deodorized camellia oil; and slowly cooling the deodorized camellia oil and performing static pressure filtering to obtain refined camellia oil.

Description

technical field [0001] The invention relates to a method for refining edible oil, in particular to a method for refining camellia oil by using tea seed crude oil. Background technique [0002] Camellia seeds grow in the subtropical mountainous and hilly areas of southern my country. Currently, the refined camellia oil supplied in the domestic market is obtained through high-temperature refining using conventional edible oil refining methods. Its purity is comparable to that of pure water. The high-temperature refined oil product not only removes harmful substances, but also causes a large loss of various functional nutrients contained in camellia oil. This part of the lost substances is biological substances with high nutritional and health effects on the human body. active substance. Today, with the advancement of science and technology, research by many famous edible oils and nutrition and health experts at home and abroad in recent years has confirmed that the edible oil i...
