Groundnut Oil Press

Groundnut oil is organic oil, aromatic and derived from peanuts. It is used in cooking as well as in the production of soap. It is basically a native from South America. Groundnut is particularly important for its protein granules which are more than meat even. Groundnuts are considered as one of the best nourishing food of the world. Apart from cooking, it is considered to have a beauty value also. To make a fresh pack with groundnut oil, it should be mixed with lime juice and applied on face at bed-time. Regular use of this pack can reduce acne and helps in skin rejuvenation. Groundnut oil is vastly used in Chinese and Indian recipes.


Groundnut oil light yellow transparent, color and clear, and fragrant smell, taste delicious, is a more easily digestible edible oil. Peanut oil containing more than 80% unsaturated fatty acids (which contains 41.2% oleic acid, linoleic acid 37.6%). It also contains palmitic acid, stearic acid and arachidic acid and other unsaturated fatty acids 19.9%.
Content from the above point of view, the fatty acid composition of peanut oil is relatively good, easy-to-human digestion and absorption. According to foreign materials, the use of peanut oil, the body can break down cholesterol and excreted as bile acids, thereby reducing plasma cholesterol levels. In addition, the peanut oil also contains sterols, wheat germ phenols, phospholipids, vitamin E, choline and other substances beneficial to humans. Regular consumption of peanut oil, can prevent aging of the skin wrinkle crack, protect blood vessel walls, preventing thrombosis, to help prevent atherosclerosis and coronary heart disease. Peanut oil in choline, but also to improve the human brain's memory, slow down brain function decline.


The Storage Method of Groundnut Oil:


1. Storage Characteristics of Groundnut oil

Groundnut oil in the general storage conditions, will occur auto-oxidation rancidity process, and its changes as follows: auto-oxidation process and the season, and if the beginning stored in the winter, low temperatures can effectively alleviate the lipase and oxygen extended style changes with the seasons , the temperature rise, the temperature at 15-30 ℃ on the one hand because of the role of lipase, so that fat hydrolysis, acid value increased, on the other hand in the air of oxygen ingress, will lead to the formation of lipid oxidation of hydrogen peroxide.
Room and library summer tank temperature exceeds 30 ℃, if stored in open tanks or in the open yard every day by the sun exposure, in this case, the environmental factors will lead to accelerated fat oxidation process. Especially in the sun in the ultraviolet or metal catalyst, when over 50 ℃, when the radiation temperature, peroxide and hydrogen peroxide will be further broken down via: Molecular re-arranged in aldehydes, ketones, so that storage of oil rancidity.


2, Groundnut Oil in Storage Measures

(1) temperature to peanut oil at a temperature below 15 ℃, full of airtight storage container, or lipase and oxygen will be the oil work, the result is the acid value and peroxide value increased, to comply with the oil storage conditions; store depot to be built underground. Because in the 4 meters below ground temperature, all year round at 20 ℃ below.
(2) long-term storage of peanut oil, add 0.2% citric acid or ascorbic acid, to destroy the catalytic metal ions, to extend the storage period. Foreign oil exports of such substances are added, and some also add anti-oxidants (such as BHA, BHT, PG, etc.).
