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.
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.
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.
What is cold pressed peanut oil?
Cold pressed peanut oils are clarified by filtration to remove proteins and other materials and pose little allergenic risks. Snack foods prepared with peanut oil include potato chips, kettle-style potato chips, extruded snacks all of which are rather high in oil content (21¨C40%).
