The peanuts are then placed in a conditioning tank, where the pressing temperature and moisture are adjusted to maximize the oil yield. To commercially extract cold-pressed peanut oil, a twin-screw press is used, and the pressing is performed at specific temperatures that do not exceed 60 °C.
What methods are used to extract peanut oil?
This review elucidates the methods used for extracting peanut oil, including mechanical and chemical processes that have been combined with biological or physical pre-treatment techniques. Their primary goals are to maximize oil extraction and unlock the untapped potential of defatted whole peanuts.
Is cold pressed peanut oil suitable for human consumption?
It is worth noting that the cold press extraction method has a relatively low oil yield (<40%), which is considered mediocre. These findings suggest that appropriate pre-treatment/extraction methods can improve the quality and yield of cold-pressed peanut oil, making it more suitable for human consumption.
What are the parameters of cold press extraction process?
Cold press extraction process parameters were flow rate (c onstant) and rotational rate 40 rpm. Se eds moistu r e an d oil contents w er e determined. Also, to tal oil contents dete rmined by th e so lvent extraction m ethod. Obtained oils fatty acids analyzed w ith two commercial oils of Iran (COI) and Turkey (COT).
