The function of steaming and frying.

The function of steaming and frying the embryo is summarized as “coagulation of oil, adjustment of structure, and improvement of oil quality”. It is embodied in the following aspects.

The function of steaming and frying

(1) Fully destroy oilseed cells. When moistened with water, the protein absorbs water and swells. It can completely “break” the unbroken cell from the inside of the cell. It enables the dispersed fine oil droplets to further agglomerate.best cold pressed walnut oil

(2) The protein is fully solidified and deformed to “harden” and become a gel with good elasticity. Improve its ability to withstand pressure, and at the same time “dredge the oil path”, which is conducive to the outflow of condensed grease. Practice has proved that the more complete the protein deformation, the higher the oil extraction rate.small groundnut oil machine

(3) The action of damp heat also causes phospholipids to absorb water and expand, and combine with proteins and carbohydrates to form solids and stay in the cake. Make the pressed crude oil clear and reduce the phosphorus content.small olive oil press

(4) Generally, the plasticity of “cooked embryo” of high temperature and low moisture is used for steaming and frying to adapt to the pressure necessary for oil extraction. Among them, the high temperature before pressing: 125~135 degrees for pressing and 110~115 degrees for pre-pressing. The viscosity of the grease is significantly reduced, which is beneficial to oil production.madhuri cold pressed groundnut oil

(5) To a certain extent, it plays the role of sterilization and detoxification. For example, passivation of lipolytic enzymes prevents the rise of acid value, so that the phenol in cotton embryo deforms and combines with protein.

(6) The side effect of steaming and frying is that the oil is easily oxidized. Pigments and lipids dissolve in the crude oil to darken the oil. Protein deformation, gossypol binding, is not conducive to comprehensive utilization of protein.cold press oil expeller machine

Edible Oil Refining is a general term for the removal of solid impurities, free fatty acids, phospholipid, colloid, wax, pigment and odors in vegetable oils. 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. However, some beneficial substances, such as tocopherol, sterol and more, will be maintained. That is why edible oil needs oil refining process.
