Diacylglycerol (DG) is a structural lipid in which fatty acids are replaced by hydroxyl groups in triglycerides (TG).
DG？ It is a trace component of natural vegetable oil, an endogenous intermediate product of body fat metabolism, and a recognized safe food ingredient (GRAS). Scientific research has found that dietary DG? It has the functions of reducing visceral fat, inhibiting weight gain and lowering blood lipid, so it has attracted wide attention.
2、? What is diglyceride oil?
Diglyceride oil is an edible oil with diglyceride as the main component. The main component of olive oil, soybean oil, rapeseed oil and other oils that people eat daily is triglyceride. The conversion from triglyceride to diglyceride can be completed by biological enzyme treatment. Diglyceride is beneficial to human health. In fact, there are also diglycerides in natural oil, but the composition is often low. But the content of diglyceride oil is above 27.3%, which will play a role in human health.
3. What is the composition of diglyceride edible oil?
Under the guidance of the national strategy of "Healthy China" and the policy of encouraging scientific researchers to actively participate in the transformation of achievements, Guangzhou Yonghua Special Medical Nutrition Technology Co., Ltd., an innovative enterprise of "Special Medical Nutrition Food", was jointly funded by South China University of Technology, Nanshan Anjie Fund and Guangzhou Eye Protection Hospital Medical Technology Co., Ltd. on 20/8/2007. The year was thus born.
Nanshan Kangzhi olive diester oil is a brand of Yonghua Special Medicine, which is a new type of high-grade edible oil with high content of diglyceride as the main component. Nanshan Kangzhi takes natural pure edible oil as raw material and converts it into natural diester oil through national core patent technology.
For example, Nanshan Kangzhi's 80% diglyceride edible oil consists of 80% diglyceride and 20% triglyceride.
20% of triglycerides are provided to the intestinal mucosa of human body for absorption, which ensures the normal fat supply of human body and gives full play to the due role of fat in human body.
4, the role of diglycerides
DAG improves blood lipid level:
The structural and metabolic characteristics of DAG are the possible mechanisms of improving postprandial blood lipid. The transformation characteristics of DAG in small intestinal epithelial cells may be the main reason why the speed and degree of postprandial blood lipid increase in DAG group are significantly lower than that in TG group.
DAG reduces body fat:
1. Increase the β -oxidation of fatty acids; 2. Affect the expression of genes related to lipid metabolism: The expression activity of genes involved in lipocatabolism is enhanced.
DAG improves blood sugar level:
The intake of DAG can reduce the blood insulin concentration and leptin concentration of diabetic patients and improve insulin resistance. Excessive fat deposition in the target tissues of insulin action in diabetic patients, such as adipose tissue, muscle and liver, leads to insulin resistance, and the intake of DAG can reduce the fat deposition in various organs, reduce the level of insulin resistance, promote the intake of glucose by cells, and thus reduce the blood sugar level. The enhancement of insulin sensitivity of tissues and organs can inhibit the secretion of islet β cells and reduce the serum insulin concentration through negative feedback regulation mechanism.
