Perilla seed oil is one of the small varieties of edible oil that has become popular in recent years. Perilla seed oil is the seed of perilla, with an oil content of about 30-45%. It is a good oil crop. Compared with corn oil, soybean oil and flaxseed oil, perilla seed oil is rich in the polyunsaturated fatty acid alpha-linolenic acid (53-62% of the oil content) and is one of the best sources of plant-based omega-3 polyunsaturated fatty acids. In addition, it also contains some other active ingredients, including palmitic acid, linoleic acid, oleic acid, stearic acid, flavonoids and vitamin E, etc., which play a role in preventing cardiovascular and cerebrovascular diseases, reducing the risk of colon cancer, delaying aging, anti-inflammatory, It plays an important role in physiological functions such as antibacterial and is also favored abroad because of its high nutritional and economic value.

The pressing method is the most commonly used and traditional method for extracting edible oil. The oil press squeezes the oil out of the raw material by applying mechanical external force to the oil. The pressing method has the advantages of simple operation, wide application range, and high production safety. However, the residual oil rate of the pressing method is relatively high. Generally, the residual oil content of the cake is about 6%-8%. Therefore, the pressing method is more commonly used for oils with high oil content, such as peanuts, rapeseeds, sesames, walnuts, etc., and the oils will be properly processed before pressing, such as crushing, steaming and frying to adjust the moisture and increase the oil yield.

Perilla seed oil is usually roasted at a high temperature of 150-250°C for 3-30 minutes, and then the ripe seeds are pressed using a press. Oils obtained by roasting at high temperatures have better flavor and color than oils obtained without roasting. Roasting treatment has a beneficial effect on the oxidative stability of perilla seed oil and the stability of tocopherols during storage at 60°C for 60 days. Therefore, proper roasting of perilla seeds before pressing and selecting the appropriate roasting temperature will significantly improve the quality and storage stability of the oil.

Through in-depth research on the medical and health care functions of a-linolenic acid, it was discovered that a-linolenic acid rich in perilla oil is the precursor of w-3 long-chain polyunsaturated fatty acids, which can be converted into Substances that have important physiological effects on the human body—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These two life-active factors called brain gold are the main components of brain cells and human nerve cells. They are also the main functional components of deep-sea fish oil, a popular health food in the world, which can lower cholesterol, lower blood pressure, improve memory, It protects eyesight, enhances immunity, delays body aging, and prevents Alzheimer's disease. It has significant effects in treating cancer, asthma, allergic diseases, cardiovascular and cerebrovascular diseases, etc. It is known as "Plant Brain" in the nutritional world. Gold" reputation.
