Embodiment 1

[0033] A method for preparing palm oil with low glycidyl ester and low 3-MCPD ester content, comprising the following preparation steps:

[0034] A, carry out degumming process to palm oil;

[0035] B, carry out solvent fractionation to the palm oil after described step A degumming treatment, then carry out deodorization treatment, obtain the grease of low diglyceride content;

[0036] C. Carry out refining treatment to the oil with low diglyceride content in the step B to obtain palm oil with low glycidyl ester and low 3-MCPD ester content.

[0037] Wherein, the degumming treatment and deodorization treatment are existing conventional processes, and the specific steps thereof will not be repeated here. The refining treatment in the step C adopts conventional process conditions for refining, and the specific steps are not repeated here.

[0038] Wherein, the solvent fractionation in the step B comprises the following steps:

[0039] (1) In a temperature-controlled stirring ...

Abstract

The invention relates to the field of refining processing of palm oil, and further relates to a method for preparing palm oil with low content of glycidyl ester and 3-MCPD ester. The method comprises: A, degumming palm oil; b, carrying out solvent fractionation on the palm oil subjected to degumming treatment in the step A, and then carrying out deodorization treatment to obtain grease with low diglyceride content; and C, refining the grease with low diacylglycerol content in the step B to obtain palm oil with low glycidyl ester content and low 3-MCPD ester content. The method effectively reduces the refining difficulty and reduces the refining cost.

Description

technical field [0001] The invention relates to the field of palm oil refining and processing, and further relates to a method for preparing palm oil with low glycidyl ester and low 3-MCPD ester content. Background technique [0002] Glycidol is a gene carcinogenic compound formed by dehydration condensation of glycerol through the 1 and 2 hydroxyl groups. IARC (International Agency for Research on Cancer), the International Agency for Research on Cancer classifies glycidol as a 2A carcinogen, which mainly exists in the form of glycidyl fatty acid esters (glycidyl esters for short) in oils, of which glycidyl oleate and glycidyl stearate, which are classified as Class 3 carcinogens by IARC. The epoxy group structure of glycidol has strong reactivity. For example, in the presence of hydrochloric acid, it is easily converted into chloropropanol, and glycidyl ester can be metabolized into glycidol in the body, which is harmful to human health. [0003] 3-Chloro-1,2-propanediol...
