This chapter covers the technology used for processing peanut oil. It starts by explaining the pretreatment technology and peanut pressing technology for high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
What technology is used for extracting peanut oil?
The leaching method, also known as the extraction method, is the technology used for extracting peanut oil. It involves using certain organic solvents that can dissolve fat to spray and immerse the oil-bearing materials, eventually separating the fat from the materials.
Which method is used to extract peanut oil?
The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [ 27 ]. The press method is to extract part of the oil in peanuts, to achieve the effect of making peanut meal at the same time, which can be divided into hot pressing method and cold pressing method.
Which solvent is used to extract residual oil from peanut press cake?
4. Conclusions The solvents hexane and ethanol were evaluated for the extraction of residual oil from peanut press cake. Ethanol exhibited a similar extraction capacity to hexane; however, the extraction conditions considering the multistage cross-current configuration were different.
