Problems solved by technology

[0002] Plasticizers or plasticizers (PAEs) are additives to food packaging materials, but their release during production, use and handling can contaminate food
A large number of studies have shown that PAEs have strong reproductive toxicity, teratogenicity, carcinogenicity and other toxicities such as causing neurological diseases and respiratory diseases, etc.

Embodiment 1

[0044] Example 1 Different phospholipase enzymatic degumming + magnesium silicate adsorption

[0045] Mix phospholipase C or A1 with water, and shear at 15000 rpm for 3 minutes (min). Then add the mixture of phospholipase and water to crude soybean oil for enzymolysis, the enzymolysis temperature is 40°C, the amount of enzyme added is 0.1% of the weight of the oil, the amount of water added is 10% of the weight of the oil, and the enzymolysis time is 4 Hour. Centrifugation was carried out after the enzymolysis was completed, and the centrifugation condition was 4500 rpm for 10 min. An enzyme-water mixture phase and an oil phase are obtained.

[0046] The oil phase obtained after the above centrifugal separation was contacted with the magnesium silicate adsorbent for 60 minutes, wherein the contact temperature was 100° C., the contact vacuum was 1013 mbar, and the magnesium silicate addition amount was 5% of the weight of the oil. After contacting for 60 minutes, carry out ...

Embodiment 2

[0050] Example 2 Enzymatic degumming + different adsorbent adsorption

[0051] Mix phospholipase A1 with water, and cut at 15000rpm for 3min. Then add the mixture of phospholipase and water to crude soybean oil for enzymolysis, the enzymolysis temperature is 40°C, the amount of enzyme added is 0.1% of the weight of the oil, the amount of water added is 10% of the weight of the oil, and the enzymolysis time is 4 Hour. Centrifugation was carried out after the enzymatic hydrolysis was completed, and the centrifugation condition was 4500 rpm for 10 min. An enzyme-water mixture phase and an oil phase are obtained.

[0052] The oil phase obtained after the above centrifugal separation was contacted with the adsorbent for 60 minutes, wherein the contact temperature was 100° C., the contact vacuum was 1013 mbar, and the amount of the adsorbent added was 5% of the weight of the oil. After contacting for 60 minutes, carry out suction filtration under reduced pressure to separate th...

Embodiment 3

[0057] Example 3 Enzymatic degumming + magnesium silicate adsorption under different conditions

[0058] Mix phospholipase A1 with water, and cut at 15000rpm for 3min. Then add the mixture of phospholipase and water to the soybean oil for enzymolysis, the enzymolysis temperature is 40°C, the amount of enzyme added is 0.01% of the weight of the oil, the amount of water added is 10% of the weight of the oil, and the time of enzymolysis is 4 hours. Centrifugation was carried out after the enzymatic hydrolysis was completed, and the centrifugation condition was 4500 rpm for 10 min. An enzyme-water mixture phase and an oil phase are obtained.

[0059] The oil phase obtained after the above centrifugation is contacted with different amounts of magnesium silicate adsorbents under vacuum conditions (vacuum degree is 5mbar), and after the end, vacuum filtration is carried out to separate the solid and liquid, and the obtained liquid is the treated Soybean oil.

Abstract

The invention relates to a method for preparing low-plasticizer-content or plasticizer-free grease, which comprises the following steps of: removing colloidal impurities in a grease raw material, andcontacting the degummed grease raw material with an adsorbent. The grease raw material is treated through degumming and adsorption processes, so that the content of the plasticizer in the grease is remarkably reduced.

Description

technical field [0001] The application relates to a method for preparing oil and a method and process for reducing the content of plasticizers in oil, in particular to a method for reducing or removing phthalates in oil. Background technique [0002] Plasticizers or plasticizers (PAEs) are additives to food packaging materials, but their release during production, use, and handling can contaminate food. A large number of studies have shown that PAEs have strong reproductive toxicity, teratogenicity, carcinogenicity and other toxicities such as causing neurological diseases and respiratory diseases. The European Union, the United States, Japan, China, etc. have successively included phthalates in the blacklist of priority control. The latest EU regulation 2011 / 10 / EC limits the migration of five PAEs in food contact materials and containers (only allowed to be used in non-greasy food contact materials): DBP is less than 0.3mg / kg, BBP is less than 30mg / kg, DEHP is less than 1...
