Peanut oil is typically isolated from peanuts using conventional extraction methods, such as mechanical pressing and solvent (n-hexane) extraction [29]. However, many of the peanut proteins are denatured as a result of high temperatures during pressing or due to exposure to the organic solvent.

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. The oil yield was not evaluated in this study, but the researchers were very interested in utilizing the by-product of this extraction (i.e., the meal), knowing that 70 kg of PDPM was

Peanut oil is extracted by employing hydraulic presses and expellers, and the method of solvent extraction. Peanut oil is rich in oleic, palmitic, and linoleic acids and possesses good oxidative stability. Aflatoxins, often present in raw contaminated peanuts, should preferably be absent in refined oil or within the legally permitted level.

A comprehensive insight into peanut: Chemical structure of

• Usage: peanut oil
• Production capacity: 1TPD-1000TPD
• Voltage: 380V
• Weight: changed with capacity
• Dimension (L*W*H): various with capacity
• Power (W): according to capacity

The oil extraction using cold-pressing method is performed at temperatures below 60 °C while in a hot-pressing condition, high temperatures are applied (Tan et al., 2020). Although peanut oil produced by hot-press is more popular due to its better aroma and flavor, it may lose its micronutrient due to proton denaturation at high temperatures.

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.

The solvent extraction of peanut oil is a process of extracting peanut oil with n-hexane as extraction solvent. The process consists of four systems: solvent extraction system, wet meal desolventizing system, mixed oil evaporation system, and solvent condensation recovery system. Here I will introduce how these systems works.

processing most widely used is the peanut oil. The peanut cake or meal obtained after oil extraction which can be full fatted, partially defatted or defatted is later used as flour, isolates and concentrates [6]. Oil extraction from the peanut kernel is a well-established industrial since the early 1950s. They have thus supported in

Bioactive Phytochemicals from Peanut Oil Processing By

The peanut-defatted peanut meal is a biowaste derived from oil extraction. It is white creamy in color and has a high protein level (>25%) [ 15 ]. In addition, peanut lectin, resveratrol, and piceid are bioactive compounds available in the defatted peanut meal [ 5 ].
