Neutralization(碱炼脱酸)

Neutralization is a refining method of separating the free fatty acids in the crude oil by the alkali liquor (NaOH solution).The resulting soap has a strong adsorption capacity, which can bring a significant amount of other impurities such as solids, proteins, colloid, pigments, etc., into the soapstock and then together been separated. 

Winterisation

The extraction of wax can improve the nutritive value of edible oil and the quality of fatty food, improve the industrial utilization value of oil and the purpose of utilizing the oil wax source. Winterization dewaxing process is based on the different freezing point of wax,saturated lipid and liquid oil, by the method of reduce the oil temperature, saturated lipid and wax will be crystallizing-out, and then separate out solid lipid (wax) and liquid oil by mechanical or solvent method, make refined oil reach the standard of freezing test.
