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 make the impurity content in the oil less than 0.2wt%. Impurities include free fatty acids, colloids, trace heavy metals, residual soap, residual debris, aflatoxin, etc.

[0052] 2. Degumming

[0053] Get 100 kilograms of tea seed crude oil with impurity content less than 0.2wt% by weight, add 5 kilograms of warm water at 40°C to the 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 crude oil was at 40° C., 2 kg of 12 wt % sodium hydroxide solution 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 separation. The acid value after deacidification is 0.12 (KOH) / (mg / g).

Embodiment 2

[0063] 1. Oil residue separation

[0064] With the help of gravity, pressure, vacuum or centrifugal force, filter cloth is used at normal temperature to make the impurity content in the oil less than 0.2wt%. Impurities include free fatty acids, colloids, trace heavy metals, residual soap, residual debris, aflatoxin, etc.

[0065] 2. Degumming

[0066] Get 100 kilograms of tea seed crude oil with impurity content less than 0.2wt% by weight, add 10 kilograms of warm water at 30°C to the 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 crude oil was at 50° C., 3 kg of 12 wt % sodium hydroxide solution 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 separation. The acid value after deacidification is 0.12 (KOH) / (mg / g).

Abstract

The invention relates to a method for refining edible oil, in particular to a method for refining camellia oil by using crude tea seed oil. The invention relates to a method for refining camellia oil with high nutrient content in order to solve the problem that the nutritional components are lost too much due to the overhigh temperature in the prior art and the like. The method mainly comprises the following steps of: preparing the crude oil at normal temperature; adding warm water and then removing impurities at the lower layer and water by a sedimental separation method; adding solution of sodium hydroxide and then removing water and nigre by the sedimental separation method; heating the crude tea seed oil to 80 to 90 DEG C, adding 1 to 3 parts of atlapulgite, cooling the mixture for 15to 20 minutes under the pressure of -0.1 to -0.095 MPa until the temperature is between 68 and 72 DEG C, and then filtering by using cotton cloth; vacuumizing to be 200 to 260 Pa at the temperature of between 140 and 150 DEG C, and distilling to obtain deodorized camellia oil; and slowing cooling the deodorized camellia oil and filtering the deodorized camellia oil under a static pressure to obtain the 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...
