EDIBLE OIL

 Refined rapeseed oil refining process

Rapeseed oil is a semi-dry oil containing erucic acid. Except for canola oil, the other varieties of rapeseed oil contain more erucic acid, which accounts for 26.3% to 57% of the fatty acid composition. High erucic acid oil is less nutritious than low-erucic acid oil, but is particularly suitable for industrial oils such as marine lubricants and tires. In the process of oil production, the mustard seed is hydrolyzed by the enzyme of mustard, forming some sulfur-containing compounds and other toxic components.This affects the quality of the oil. The general smelting process has a very low removal rate of sulfides. Therefore, edible rapeseed oil should be refined.

Palm oil refining process

Palm oil is obtained from palm fruit pulp. Its fatty acid composition accounts for 40% to 50% of saturated acid, 80% of which is palmitic acid, oleic acid is the main unsaturated acid, followed by linoleic acid. Because palm fruit is decomposed by lipolytic enzymes before harvesting and oil production, combined with processing methods and storage and transportation conditions, the free fatty acid content of palm oil is comparatively high. It is generally about 10%, and high level is more than 30%.
