Oil pretreatment is a very important part in the processing of edible oil, which plays a vital role in the quality and taste of edible oil. Oil pretreatment includes cleaning, peeling, crushing, drying and other steps, so what role does the oil pretreatment play in the processing of edible oil?

First of all, oil pretreatment can effectively remove impurities and moisture in oil. Oilseeds are often polluted by the external environment in the process of planting, picking and transportation, such as dirt, branches, leaves and other impurities will be mixed into the oil, and moisture will cause the oil to be moldy and deteriorated. Through cleaning and drying, these impurities and moisture can be effectively removed to ensure the purity and dryness of oil, which provides good conditions for subsequent processing technology.

Secondly, oil pretreatment can improve the oil extraction rate and oil stability. Oil contains a certain amount of oil. Pretreatment processes such as crushing and heat treatment can effectively destroy the cell structure of oil, release more oil and improve the extraction rate of oil. At the same time, heat treatment can also reduce the content of free fatty acids and other harmful substances in oil, improve the stability of oil and extend the shelf life of edible oil.

In addition, oil pretreatment can also improve the taste and nutritional value of edible oil. After careful pretreatment, it can ensure the clear color and delicate taste of edible oil, and at the same time, it can retain more nutrients, such as vitamin E and unsaturated fatty acids, making edible oil healthier and more nutritious.

In a word, oil pretreatment plays an important role in the processing of edible oil, which can not only improve the quality and output of edible oil, but also ensure the safety and nutritional value of edible oil, and is an indispensable part in the production of edible oil. With the continuous progress of science and technology and the continuous improvement of technology, it is believed that oil pretreatment technology will develop more and better applications in the future, bringing healthier and more delicious edible oil products to people.
