Bioactive Phytochemicals from Peanut Oil Processing By-products - Springer
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 ].
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 ].
Mechanical Methods of Oil Extraction from Peanuts
In 2020, Shin et al. extracted oil from peanuts using the cold pressing method and aimed to valorize the partially defatted peanut meal (PDPM) obtained . In the process of producing cold-pressed peanut oil, mechanical shelling is commonly used, and the peanut kernels with red skin are then dehydrated to a moisture content of 4–8% to make them easier to peel.
Cold pressed peanut meal, also known as defatted peanut meal or pressed peanut meal, is a by-product of peanut oil extraction. It contains a high protein level (> 25%), and is white to creamy in color due to the mild thermal (< 60°C) treatment (Zheng et al., 2013). Cold pressing of 100 kg peanut kernels can generate 70 kg of defatted peanut
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.
Peanut oil is considered as a premium edible oil and commands a high price in both US and European markets. 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
Boost yield in peanut oil with optimal processing
Step 3: Pressing and extraction. The roasted peanuts are then subjected to mechanical pressing or the chemical method solvent extraction. While both methods are part of the peanut oil production line, they have different outcomes. Mechanical pressing involves the mechanical screw, screw shaft, and the embryo slice to extract oil.
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.
- How is cold pressed peanut oil extracted?
- 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.
- 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.
