Peanut proteins: Extraction, modifications, and applications: A
The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [27]. The press method is to extract part of the oil in peanuts, to achieve the effect of making peanut meal at the same time, which can be divided into hot pressing method and cold pressing method.
Oil extraction Oil contains high amounts of energy and fat-soluble vitamins (A, D, E, and K) and essential fatty acids. The oil content of the kernels is between 45% and 55%. The peanuts are prepared for the oil extraction process by being shelled and cleaned. Oil production requires some type of press with which to extract the oil form the
Mechanical Methods of Oil Extraction from Peanuts
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 recovered out of 100 kg of peanuts [ 21 ] .
2 Chemical Composition and Bioactive Compounds of Extracts from Peanut Oil-Processing By-Products. The edible kernel comprised about 68–72% of the peanut, while the balance 28–32% is the peanut hull [ 8 ]. Peanut kernel’s average thickness, width, and length are 6.9 mm, 3.6 mm, and 8.5 mm, respectively [ 9 ].
Defatting and Defatted Peanuts: A Critical Review on Methods of Oil

In 2018, peanut oil sold for US$1470/MT in the United States and for US$1326 in Rotterdam. Peanut oil is recovered primarily by expeller pressing or in combination with hexane extraction. Only four plants process peanut oil in the United States. Peanut oil is processed by conventional caustic refining, adsorbent bleaching, and deodorization.
Defatting and Defatted Peanuts: A Critical Review on Methods of Oil
frying of peanuts before they are cold-pressed, with the resulting peanut oil then being filtered [ 20 ]. In 2017, Chen et al. examined the effects of pressing temperature and moisture content,
The conditioned peanut kernels are transported by a conveyor to the twin-screw press for cold pressing; the cold-pressed crude oil and cold-pressed peanut meal with low denaturation will be obtained. After the cold-pressed crude oil is filtered with frame filter, product oil is obtained, which will be packaged by a filling machine to form cold-pressed peanut oil products ( Fig. 3.8 ).
- What is peanut oil processing technology?
- This chapter covers peanut oil processing technology. It starts by explaining the pretreatment technology and peanut pressing technology of high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
- Is oil extraction from peanuts environmentally friendly and cost-efficient?
- A comparison in terms of productivity, efficacy, specificity, quality of the extracts, and operating conditions was conducted, which favored the novel methods as being mostly environmentally friendly and cost-efficient. Chemical methods of oil extraction from peanuts.
- Which method is used to extract peanut oil?
- The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [ 27 ]. The press method is to extract part of the oil in peanuts, to achieve the effect of making peanut meal at the same time, which can be divided into hot pressing method and cold pressing method.
- How to make peanut oil in China?
- Currently, there are two pressing methods: high-temperature pressing and cold pressing. More than 90% of oil production in China adopts the traditional technique of high-temperature pressing, and the peanut oil produced with this method has a strong fragrant flavor and is therefore greatly favored by consumers.
