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 is cold pressed peanut oil?
Cold pressed peanut oil is composed mostly of unsaturated fatty acids, predominantly oleic and linoleic acids. Moreover, the oil is also rich in bioactive components such as tocopherols, phenolic acids, and phytosterols. Cold pressed peanut meal, also known as defatted peanut meal or pressed peanut meal, is a by-product of peanut oil extraction.
What equipment is used for cold pressing of peanut oil?
Figure 3.8 shows the equipment used for cold pressing of peanut oil. First, a sheller is used to shell the peanuts. Then, the peanut kernels are transported to the low-temperature drying oven for drying after being subjected to precleaning, gravity/magnetic separation, and de-stoner cleaning.
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.
