In the production process of edible oil, oilseed pretreatment is a crucial link. Oilseed pretreatment not only directly affects the extraction efficiency of oil, but also affects the quality and taste of the final product. Through scientific and reasonable pretreatment technology, the oil yield can be improved, the energy consumption can be reduced, and the edible oil can meet the food safety standards.

First of all, oilseed pretreatment is the key step to improve oil yield. Different oilseeds, such as soybean, peanut and rapeseed, have different structures and oil contents. Without proper pretreatment, it is difficult to completely release the oil in the raw materials, resulting in a decrease in oil yield. Common pretreatment processes include cleaning, crushing, softening, embryo rolling, steaming and frying, etc. These steps can effectively destroy the cell structure of raw materials and make the oil easier to extract.

Secondly, pretreatment has a direct impact on the quality of edible oil. For example, in the cleaning stage, impurities such as sediment, metal fragments and plant residues can be removed, which can prevent impurities from entering the subsequent processes and ensure the purity of oil products. In the process of steaming and frying, the flavor and stability of oil can be improved by adjusting the temperature and time, and at the same time, the generation of harmful substances can be reduced. Reasonable pretreatment can also reduce the content of phospholipids and free fatty acids in oil, thus improving the quality of refined oil.

In addition, pretreatment can also reduce production costs and improve production efficiency. By optimizing the pretreatment process, the wear of mechanical equipment can be reduced, the service life of the equipment can be prolonged and the energy consumption can be reduced. For example, the softened raw materials are easier to be squeezed or leached, thus reducing the pressure and energy consumption of equipment operation. This not only helps enterprises to save costs, but also conforms to the development trend of green environmental protection in modern food industry.

To sum up, oilseed pretreatment is an indispensable part in edible oil production. It not only determines the oil yield and product quality, but also relates to production efficiency and food safety. Only by paying attention to and optimizing the pretreatment process can we produce high-quality, safe and healthy edible oil, so as to meet the market demand and consumer expectations.
