Problems solved by technology

However, high-temperature fried seeds destroy the cell structure, improve the oil yield and the flavor of the oil, and also cause the caramelization and dehydration of the sugar in the oilseed to form benzopyrene. The high-temperature pretreatment process will lead to an increase in the content of benzopyrene is a strong carcinogen
At present, the removal of benzopyrene in oil is mainly adopted by the adsorption method. This method will also adsorb the aroma components of oil while adsorbing benzopyrene, and the analysis and treatment after adsorption are very difficult.

Embodiment 1

[0023] Embodiment 1: adopt DNA solution to add in the grease and realize the removal effect of the benzopyrene of tea seed oil, its technical method comprises the following steps:

[0024] 1. Weigh 100g of crude oil and place it in a 250ml beaker.

[0025] 2. Determine the water weight W: the phospholipid content of tea seed oil is generally 12.5g / kg, because this process can completely borrow the oil hydration and degumming process, so the amount of water added can be determined according to the phospholipid content in the oil, and the calculated water addition is 3.7 g.

[0026] 3. Determine the weight of DNA added A: Add 0.0002 g of DNA to the above water and mix to obtain a DNA aqueous solution.

[0027] 4. After starting to heat the crude oil to a temperature of 55-65°C, adjust the stirring speed to 50-70r / min, slowly add the DNA aqueous solution into the oil, and keep stirring at a constant temperature of 55-65°C for 20-40min.

[0028] 5. Keep constant temperature afte...

Embodiment 2

[0031] Embodiment 2: adopt DNA solution to add in the grease and realize the removing effect of the benzopyrene of peanut oil, its technical method comprises the following steps:

[0032] 1. Weigh 100g of crude oil and place it in a 250ml beaker.

[0033] 2. Determine the water weight W: The phospholipid content of peanut oil is generally 10g / kg, because this process can completely borrow the oil hydration and degumming process, so the amount of water added can be determined according to the phospholipid content in the oil, and the calculated water addition is 3.0g.

[0034] 3. Determine the weight of DNA added A: Add 0.0002 g of DNA to the above water and mix to obtain a DNA aqueous solution.

[0035] 4. After starting to heat the crude oil to a temperature of 55-65°C, adjust the stirring speed to 50-70r / min, slowly add the DNA aqueous solution into the oil, and keep stirring at a constant temperature of 55-65°C for 20-40min.

Abstract

The invention relates to a process method for removing benzopyrene in grease. The grease is eluted by adopting DNA (deoxyribonucleic acid) aqueous solution; the benzopyrene in the grease is intercalated with DNA; DNA is dissolved in water, so that the benzopyrene intercalated with the DNA is brought into the water; oil cannot be dissolved in water, so that after standing, separation is carried out to obtain the grease of which the benzopyrene is removed. Currently, removal on the benzopyrene in the grease mainly adopts an adsorption method, such method can also adsorb aroma components in the grease when adsorbing the benzopyrene, and resolving and processing after adsorption are very difficult. According to the process method disclosed by the invention, the adsorption method for removing the benzopyrene is improved; by improvement, grease loss is effectively reduced, a removal effect is improved, and post-processing difficulty is reduced; meanwhile, the process method has the advantages of convenience for use, low cost, low investment and the like, and is suitable for various large and medium-sized grease machining enterprises.

Description

technical field [0001] The invention relates to a process method for removing benzopyrene from oil. Background technique [0002] my country's oil industry has entered a stage of rapid development. At this stage, the method for producing vegetable oil with special aroma is mainly the pressing method. In order to completely squeeze the oil in the oilseed, the cell structure of the oilseed must be completely destroyed. , so a common way to destroy the cell structure is high-temperature frying seeds. High-temperature frying seeds can not only destroy the cell structure of oilseeds, but also release aromatic components, so the oil has a strong aroma. However, high-temperature fried seeds destroy the cell structure, improve the oil yield and the flavor of the oil, and also cause the caramelization and dehydration of the sugar in the oilseed to form benzopyrene. The high-temperature pretreatment process will lead to an increase in the content of benzopyrene Is a strong carcinogen....
