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.
Can peanut oil be removed by hot pressing method?
Although up to 80%¨C90% oil can be removed by hot pressing method, most proteins in peanut meal will be denatured and the content of water-soluble proteins and functional properties will be decreased obviously due to high-temperature treatment. The general cold pressing process is processed in an environment below 60 °C.
Which countries produce the most peanuts in the world?
According to statistics, the annual global production of peanuts is around 45 million metric tons [ 2 ]. The major countries involved in peanut production are China, India, Nigeria, and the United States. Peanuts contain around 24% to 36% crude protein on a dry weight basis, which is second only to soybean (36% to 51%) in edible oil crops [ 3 ].
Which method is used to extract peanut protein?
The extraction method used significantly affects the structural, functional, and physicochemical properties of peanut protein ingredients. The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [ 27 ].
