The production of peanut oil involves several technologies. It starts with pretreatment technology and peanut pressing technology for high temperature and cold pressing. The oil is then extracted using leaching and separation technology. At the end of the process, the peanut oil production line and the relevant key equipment are discussed. (Section 3.1)
How is peanut oil processed?
Only four plants process peanut oil in the United States. Peanut oil is processed by conventional caustic refining, adsorbent bleaching, and deodorization. The food uses of peanut oil and protein are reviewed in this article. Abstract This article reviews the production, processing, and food uses of peanut oil and protein.
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.
How to extract oil from peanuts?
Chemical methods of oil extraction from peanuts. 3.1. Organic Solvent Extraction When extracting oil from oilseeds, the organic solvent is used to separate crude vegetable oil from the meal, which contains both proteins and carbohydrates too. The most frequently utilized organic solvent for this process is hexane [ 18, 71 ].
