Research Status of Plasma Activation Technology and its Prospect for Deer Oil Refining Process

Deer oil has natural ingredients, which can penetrate epidermal cells and maintain its biological activity. At the same time, it also gets the effects of delaying skin aging and preventing skin diseases. In view of the industrial pain point of low utilization rate and serious waste of deer fat in the processing of deer products, taking sika deer oil as raw material, different methods of deer oil extraction processes are summed up. In view of the characteristics of plasma activation technology, such as sterilization and odor removal, plasma technology is proposed to refine deer oil in order to remove the bad flavor of deer oil and prolong the storage time, It provides a reference for the development and application of deer oil and its series products. Compared with ordinary vegetable oils, animal oils such as pigs, cattle, sheep and deer are commonly used in food processing industry because of their irreplaceable unique flavor [1]. In recent years, with the continuous improvement of people's pursuit of quality of life, it is found that the cholesterol content of some animal fats is high, which has a negative impact on health. Therefore, animal fats gradually fade out of people's table. With the rapid development of the processing industry and the continuous improvement of technology, animal oil is commonly used in washing, lubrication, cosmetics and other fields, and the market potential is huge. Therefore, it is of great significance and socio-economic value to study the extraction process of animal oil. Sika deer is a precious animal with medicinal value. Antler and deer fetus is more and more favored by people as health products, but a large amount of deer fat is not fully utilized as production waste every year [2]–[3]. Deer oil is easily absorbed by the skin and has the effects of anti-oxidation, delaying the skin aging, moisturizing and moisturizing, nourishing the skin [4]–[8]. Plasma is called the fourth state except gas, liquid and solid. In recent years, plasma technology is widely used in the field of materials, which can realize the surface cleaning and etching of materials, and is utilized for the oxidation and reduction of catalytic materials [9]–[10]. This paper briefly discusses the main extraction methods of deer oil in the industrial field, and puts forward a method of purifying deer oil by plasma technology.
