What raw materials can be used to extract oil

Oil is an indispensable part of ordinary people's daily life, but due to the serious safety problems of edible oil in recent years, waste oil is afraid to eat, and genetically modified oil has doubts, more and more consumers want to eat safe and healthy oil , Because the oil press has become a new business opportunity for many investors. Wangquan brand automatic oil press is a technological pioneer in China's oil press equipment, grain and oil machinery and oil and fat equipment. The oil press is widely used in oil production of sesame, rapeseed, peanut, cottonseed, soybean, tea seed, corn germ and other oil crops. Wangquan brand automatic oil press (vacuum oil press, multi-function oil press, peanut oil press, soybean oil press, rapeseed oil press, sesame oil press) is the center of entrepreneurial investors and army life, The best choice for hotels, large and medium-sized canteens and other units and individuals.

Oil press raw material

The raw materials of oil press, that is, oil crops, are divided into plant raw materials and animal raw materials according to their types. In the general production process, we mainly use plant raw materials. The plant raw materials are divided into legumes, seed families and hemp families. The following is a brief description of my country's oil crops:

Peanut: Peanut is a bean crop, and historically it was called longevity fruit, ginseng, ground pine, longevity fruit, fig, etc. Peanut nourishes the stomach and prolongs life. It is also known as "longevity fruit" in the folk, and is known as "vegetable meat" and "meat in vegetarian food" like soybeans. The nutritional value of peanuts is higher than that of grains, and it is comparable to some animal foods such as eggs, milk, and meat. It contains a lot of protein, especially the content of unsaturated fatty acids.

Peanuts are annual herbs. It is also an important oil crop with many varieties. The chemical composition of general peanuts is: moisture 5.33%~9.16%, oil 44.27%~53.86%, carbohydrates 9.89%~23.62%, protein 23.96%~33.94%, phospholipids 0.5%~ 1.5%, crude fiber 2.67%~5.26%, ash content 1.75%~2.58%. It can be seen that peanut contains a lot of oil (fat) and protein, and is a good oil crop, of which 23.96%~33.94% protein is more than lean pork, The protein of beef and mutton is 1.5-2.5 times higher; 5-13 times higher than that of rice and flour, and the protein has a high digestibility coefficient, which is rich in amino acids needed by the human body; vitamin B1, B6, vitamin D, E, calcium and phosphorus, etc. minerals. my country's peanut planting area ranks second in the world. For a long time, peanut series products have been well received by consumers. But the fly in the ointment is that "the peanut has a high fat content, and the taste is too greasy when eaten, which leads to the occurrence of a series of fatty diseases in the human body. The raw materials for oil extraction in North China are generally peanuts.

Soybean: belonging to the legume family, it is an annual herb whose seeds are also called soybeans. The most important legume in the world. Soybean originated in China, and most Chinese scholars believe that the origin is the Yunnan-Guizhou Plateau. There are also many botanists who believe that it is derived from the Ussuri soybean originating in China. The cultivated soybeans that are currently planted are domesticated from wild soybeans through long-term directional selection and improvement. Soybean is rich in high-quality protein, unsaturated fatty acids, calcium and B vitamins, which is an important source of high-quality protein in the diet of Chinese residents. The protein content of soybean is about 35%-40%. Except for methionine, the composition and proportion of other essential amino acids are similar to those of animal protein, and it is rich in lysine, which is lacking in cereal protein. It is a natural ideal food complementary to cereal protein. The fat content of soybean is about 15%-20%, of which unsaturated fatty acid accounts for 85%, linoleic acid is as high as 50%, and the digestibility is high, and it also contains more phospholipids. The carbohydrate content in soybean is about 25%-30%, half of which is dietary fiber, of which raffinose and stachyose are fermented under the action of intestinal bacteria to produce gas, which can cause abdominal distension. Soybeans are rich in phosphorus, iron, and calcium. Each 100g of soybeans contains 571mg of phosphorus, 11mg of iron, and 367mg of calcium, which is significantly more than that of cereals. Because the relative oil yield of soybeans is low, the oil is generally used for extraction by leaching. General oil production enterprises in my country use foreign genetically modified soybeans as raw materials, because genetically modified soybeans contain as much as 25%-35% oil.

Sesame: (scientific name: Sesamum indicum), the sesame family, is the seed of flax. Although its close relatives appear in Africa, the natural origin of the breed is still unknown. It is found in tropical regions of the world. Sesame is one of the four major edible oil crops in my country and one of the main oil crops in China. Sesame products have high application value. The oil content of its seeds is as high as 61%. Since ancient times, there have been many famous special foods and delicacies made of sesame and sesame oil in my country, which have been famous all over the world. Sesame flowers solitary, or two or three clusters in leaf axils. Cylindrical, lip-shaped, made of sesame (14 photos) light red, purple and white. Due to different varieties, the number of ridges of the long cylindrical capsule varies from 4.6.8. The seeds are oblate, white, yellow, brown-red or black. The white seeds have higher oil content, and the black seeds are used as medicine. Sesame oil contains a lot of essential fatty acids, and the content of linoleic acid is as high as 43.7%, which is higher than that of vegetable oil and peanut oil. Aromatic oils can be extracted from the stems, leaves and flowers of sesame seeds. The oil produced by pressing sesame is commonly known as sesame oil. It has a mellow and rich smell and is an important seasoning and cooking oil.

Rapeseed, also known as oil cabbage, bitter cabbage, is the tender stem and leaves of the cruciferous vegetable rapeseed. It is native to my country and has a dark green color. It is like cabbage. It is a variant of cruciferous cabbage. It is widely cultivated in the north and south, and is available in all seasons. Rape contains a variety of nutrients and is rich in vitamin C. The northern rapeseed is native to western China, and is distributed in Northwest China, North China, Inner Mongolia and the provinces (regions) in the Yangtze River Basin and is also widely distributed around the world. Vegetable oil contains a variety of vitamins, such as vitamin A, vitamin D and vitamin E, which is an important source of fat-soluble vitamins in the human body. Vegetable oil is rich in vitamin E, up to 60 mg/100 g of oil, especially vitamin E content of 13 mg/100 g of oil, which is 2.6 times that of soybean oil, and it does not decrease much after long-term storage and heating. Sources of vitamin E in food. Rapeseed contains 45% oil, and the linoleic acid content also rises to about 20%, so that the fatty acid composition of canola oil is similar to that of tea oil and peanut oil. In recent years, the successful cultivation of low-linolenic acid rapeseed has reduced the content of linolenic acid, which is highly susceptible to oxidative deterioration and hinders the metabolism of linoleic acid, to about 3%, so the drawbacks of the high content of erucic acid and linolenic acid in the original conventional rapeseed oil have been eliminated. Completely overcome, more than 90% of the fatty acids in rapeseed oil are essential fatty acids - linoleic acid and oleic acid with high nutritional value.

Flaxseed: Flaxseed is an oil crop, and linseed oil contains polyunsaturated fatty acids, so it is used to prevent hyperlipidemia and atherosclerosis. The surface of flax seeds is mostly reddish-brown or taupe, tan, a few golden yellow and white, the surface is smooth and shiny, the oil content is 30%-45%, linseed oil is rich in unsaturated fatty acids such as linolenic acid and linoleic acid, especially It is rich in a-linolenic acid and r-linolenic acid necessary for the human body, of which a-linolenic acid accounts for 57% of the fatty acid of linseed oil, which is 2 times higher than that of fish oil. It can reduce human blood pressure, serum cholesterol and blood viscosity, and has therapeutic effects on cancer, cardiovascular disease, internal organ disease, kidney disease, skin disease, arthritis, lung disease, and immune system diseases. More than 30 countries such as the United Kingdom and France have approved the use of linseed oil as a nutritional additive or functional food. Flax oil is the oil extracted from the seeds of the Flax plant. Linseed contains 30% to 48% of oil. The oil obtained by pressing at room temperature is a yellow liquid with a specific smell. The texture gradually becomes thicker and the color becomes darker in the air. The main components of the oil contain linolenic acid and linoleic acid. , oleic acid, palmitic acid, stearic acid and other glyceric acids. In addition, it also contains organic compounds such as eicosyl ferulic acid, various steroids, triterpenes, and cyanosides. Flax oil is mainly used as an industrial raw material for coatings, inks, tarpaulins, rubber, etc. Traditionally used as cooking oil in a small number of areas. It has certain medicinal value.
