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.
How is cold pressed peanut oil extracted?
Commercial cold pressed extraction of peanut oil is carried out using a twin-screw press at temperatures below 60°C ( Wang, Liu, Hu, et al., 2016; Zheng, Ren, Su, Yang, & Zhao, 2013 ). Lastly, a frame filter is used to press and filter three times under 30°C to obtain the cold pressed peanut oil ( Wang, Liu, Hu, et al., 2016 ).

How much tocopherol is in cold pressed peanut oil?
Velikovska et al. (2016) reported that the total tocopherol content of cold pressed peanut oil was 295.6 mg/kg. Their study showed that cold pressed peanut oil contained almost the same amounts of ¦Á- and ¦Ã-tocopherol content (143.9 and 145.1 mg/kg, respectively).
