Bis-glycerol fatty acid esters are not trans fats per se, although it is possible to form trans fatty acids from bis-glycerol fatty acid esters. Glycerol fatty acid esters refer to a mixture of glycerol and fatty acid concentrates, including monoglycerol fatty acid esters, diglycerol fatty acid esters, and triglycerol fatty acid esters, three common types, of which diglycerol fatty acid esters and triglyceride esters are more similar, and there is a possibility that trans fatty acids may be formed during the process of production. Bis-glycerol fatty acid esters are unsaturated fatty acids that contain a hydrophilic hydroxyl group, which can react with water to form stable hydrated dispersions, and are usually used as food additives, mainly for making artificial cream, ice cream, chocolate, bread and other foods. When consumed for a long period of time, it can easily lead to an increase in body fat content, which in turn increases the risk of obesity. Therefore, try to maintain a healthy diet in your daily life, eat less food containing additives such as diglyceride fatty acid esters, and eat more fresh vegetables and fruits. If necessary, consult a medical professional to develop an individualized diet plan.
