Peanuts oil
Peanuts are oil and food dual-use resources with abundant production. They are mainly distributed in Asia, Africa and the Americas. The main producing countries are China, India, Indonesia, Myanmar, Nigeria, the United States and Argentina.
Peanut Oil
Peanut oil is a non-drying vegetable oil, the iodine value is generally between 80 and 107. The specially processed peanut oil has an attractive and rich fragrance and it is a kind of edible oil with high market value. Because it contains a high proportion of unsaturated fatty acids, monounsaturated fatty acids accounted for 49%, polyunsaturated fatty acids accounted for 30%, especially the human essential fatty acid-arachidonic acid, which has a higher nutritional value. In addition, peanut oil also has a lighter color, lower phospholipid content, a higher smoke point and better sensory indicators and cooking performance.
Processing technology of peanut
Peanut kernels have high oil content, and there are three main oil-making processes: traditional pre-press extraction process, aromatic peanut oil process, cold-pressed peanut oil and peanut protein powder process. At present, the oil-making process mainly adopts the fragrant peanut oil process, that is, the oil-making method of mixing and pressing fried seed peanut kernels and steamed peanut embryos (see Figure 1).

Processing technology of peanut
The fragrant peanut oil process uses high-quality fresh peanut kernels as raw materials, and adopts some whole seeds special high-temperature frying, mixed mechanical pressing, and low-temperature cold filtration process to produce peanut oil with strong fragrance.
High-temperature pressed peanut cake (about 8% oil), after solvent extraction, the obtained crude oil can be refined through alkali refining, deacidiication, decolorization, and deodorization to produce national standard first-class edible peanut oil.
Peanut meal (residual oil less than 1%) can be used as feed.
