Description
Technical field
The present invention relates to the refining manufacture field of palm oil, a kind of low ethylene oxidic ester and low of preparing is further related to
The method of the palm oil of 3-MCPD ester content.
Background technique
Glycidol is a kind of with gene tumorigenic compound, is condensed and is formed through 1,2 hydroxyls dehydrate by glycerol.IARC
(International Agency for Research on Cancer), glycidol is classified as by international cancer research institution
2A class carcinogenic substance mainly exists in grease in the form of glycidol aliphatic ester (abbreviation ethylene oxidic ester), wherein shrinking
Glyceryl oleate and glycidol stearate are classified as 3 class carcinogenic substances by IARC.The epoxy based structures of glycidol have very strong
Reactivity be easily converted into chloropropyl alcohol such as in the presence of hydrochloric acid, ethylene oxidic ester is metabolizable in vivo to endanger for glycidol
Evil human health.
The chloro- 1,2- propylene glycol (3-MCPD) of 3- has Toxicity of Kidney, genotoxicity, neurotoxicity, immunotoxicity, mutagenesis
Property and carcinogenicity, IARC are classified as 2B class carcinogenic substance.Mainly with 3-MCPD aliphatic ester (abbreviation 3-MCPD ester) in grease
Form exist, 3-MCPD ester is metabolized as 3-MCPD and endangers health through hydrolysis in vivo other than the toxicity of itself.
Researchers at home and abroad detect 3- in the food from numerous food such as animal and plant fat and containing animal and plant fat
MCPD ester and ethylene oxidic ester draw especially in baby milk powder after the 3-MCPD ester and ethylene oxidic ester of discovery high concentration
Play the great attention of government and oil prodution industry.And refined palm oil is one of large glyceride stock, is answered extensively in the food industry
With, however it has the risk of high ethylene oxidic ester and high 3-MCPD ester content level, keeps the use of palm oil strong for human body
Health is there are certain harm, using having some limitations.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention, which provides, a kind of prepares low ethylene oxidic ester and low 3-MCPD ester content
Palm oil method, this method is easy to operate, and condition is controllable, and the content of the ethylene oxidic ester in palm oil obtained is in 1ppm
