1. Insoluble solid impurities, such as sand, cake powder, fiber, etc., clay, catalyst, etc.

2. Peptide-soluble impurities, such as FFA, vitamin E, pigments, vitamins, gossypol, etc.

3. Volatile impurities: such as moisture, odorous substances, etc.

Most impurities are detrimental to oil quality and storage safety. For example, moisture not only affects the transparency of oil but also promotes the hydrolysis and rancidity of oil. savaliya cold press oil machine Insoluble impurities and acidic substances are both promoting factors of oil deterioration. FFA affects flavor and promotes deterioration. Phospholipids can make oil cloudy, and when heated, it will produce black deposits, bubbles, bitterness, etc.napa valley sesame oil

The presence of impurities contained in crude oils not only affects the use value, the safety storage of crude oil, but also cause difficulties for the deep processing crude oils. Edible oil refining is not only removes all the impurities out from the crude oils, but also refines harmful impurities, such as, gossypol, protein, lecithin, mucus, water and more. In this way, the edible oils can have better storage, industrial applications and cooking purpose.
