Problems solved by technology

[0004] 1. Most of the degumming process adopts the hydration degumming process, which takes a long time and consumes a lot of water, which is easy to cause water pollution and high cost
[0005] 2. Incomplete removal of residual industrial alkali during alkali refining
[0006] 3. The adsorbent used in the deodorization process tends to be diatomite, which will cause the acid value of the oil to rise and the finished oil will have a muddy smell, which will affect the quality

Embodiment 1

[0028] The concrete steps of the refining process of the deacidification and deodorization of Ingot Maple Oil of the present invention are as follows:

[0029] (1) Degumming: degumming by medium temperature acidification method,

[0030] Put the ingot maple seed oil into the deacidification tank, then heat it to 55°C, then add a phosphoric acid solution with a mass concentration of 85%, the amount added is 0.05% of the weight of the ingot maple seed oil, and then stir for 25min at a speed of 55r / min , then add 8% brine of the weight of ingot maple seed oil, let it stand for 30min, and release the brine from the bottom of the tank;

[0031] (2) Deacidification: Deacidification is the use of dilute sodium hydroxide solution to neutralize free fatty acids in oils, also known as alkali refining.

[0032] Add sodium hydroxide solution to the tank while stirring, the content of sodium hydroxide in the solution is 8.5%, the temperature of sodium hydroxide solution is 58°C, the stirr...

Embodiment 2

[0040] The concrete steps of the refining process of the deacidification and deodorization of Ingot Maple Oil of the present invention are as follows:

[0042] Put the ingot maple seed oil into the deacidification tank, then heat it to 62°C, then add a phosphoric acid solution with a mass concentration of 85% in an amount of 0.2% of the weight of the ingot maple seed oil, and then stir for 20min at a speed of 60r / min , then add 10% brine of the weight of ingot maple seed oil, let it stand for 30min, and release the brine from the bottom of the tank;

[0043] (2) Deacidification: Deacidification is the use of dilute sodium hydroxide solution to neutralize free fatty acids in oils, also known as alkali refining.

[0044] Add sodium hydroxide solution to the tank while stirring, the content of sodium hydroxide in the solution is 10%, the temperature of sodium hydroxide solution is 66°C, the stirring sp...

Embodiment 3

[0052] The concrete steps of the refining process of the deacidification and deodorization of Ingot Maple Oil of the present invention are as follows:

[0053] (1) Degumming: Degumming by medium temperature acidification method,

[0054] Put the ingot maple seed oil into the deacidification tank, then heat it to 60°C, then add a phosphoric acid solution with a mass concentration of 85% in an amount of 0.1% of the weight of the ingot maple seed oil, and then stir for 25 minutes at a speed of 60r / min , then add 9% brine of the weight of Ingot Maple Seed Oil, let it stand for 30 minutes, and release the brine from the bottom of the tank;

[0055] (2) Deacidification: Deacidification is the use of dilute sodium hydroxide solution to neutralize free fatty acids in oils, also known as alkali refining.

[0056] Add sodium hydroxide solution to the tank while stirring, the content of sodium hydroxide in the solution is 9%, the temperature of sodium hydroxide solution is 60°C, the sti...

Abstract

The invention discloses a deacidifying and deodorizing refining process of acer truncatum oil. The deacidifying and deodorizing refining process of acer truncatum oil disclosed by the invention comprises the following steps of: (1) degumming; (2) deacidifying; (3) dehydrating and decolouring; and (4) deodorizing. Acer truncatum oil prepared by using the process disclosed by the invention is stored by using a stainless steel tank; the tank is fully filled and sealed after being filled with nitrogen; and the acer truncatum oil is stored at normal temperature. The deacidifying and deodorizing refining process of acer truncatum oil disclosed by the invention is low in cost and easy to operate; the components, such as phospholipid, moisture, protein and the like, are eliminated to the most extent; the beneficial components, such as sterol, nervonic acid and the like, are reserved; and the edible value and the storage value of acer truncatum seed oil are greatly increased.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a refining process for deacidification and deodorization of ingot maple oil. Background technique [0002] Yuanbao maple kernels contain high-quality protein, and the oil content reaches 48%. In 2011, the Ministry of Health approved Yuanbao Maple Seed Oil as a new resource food (Ministry of Health Announcement No. 9 in 2011). The content of unsaturated fatty acids in the oil reached 92%, of which the essential fatty acids for human body were as high as 53%, and the content of nervous acid was more than 5% ( Nervous acid is recognized by scientists from all over the world as the only double-effect magical substance in the world that can repair damaged brain nerve pathways—nerve fibers and promote nerve cell regeneration). Yuanbao maple oil is also a high-quality edible oil and cosmetic raw material oil that needs to be developed urgently. Regular consumption of Yuanbao...
