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 is peanut oil processing technology?
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.
Why did peanut oil production increase in the 1990s?
In the 1990s, the average annual processing volume of peanuts increased by nearly 40% compared with that in the 1980s in China. The peanut oil preparation is the main method to use peanuts, and the oil yield and peanut oil quality have been improved continuously due to the continuous improvement of processing process and peanut quality.
Where does peanut oil come from?
Peanut (groundnut, earth nut) oil production worldwide was about 5.4 million metric tons (MMT) in 2012/2013 and has remained fairly static over the past decade ( USDA, FAS, 2014 ). Worldwide, peanut seed production amounts to about 37 MMT primarily from China, India, US, Nigeria, and Indonesia with the remainder 15% from 15 other countries.
