Vegetable fat powder, also known as milk essence, is a new product with refined vegetable oil, hydrogenated vegetable oil and casein as the main raw materials. The product plays a special role in food production and processing, and is also a kind of modern food.
Recent studies have shown that the partial hydrogenation of vegetable oil is actually the process of transforming unsaturated fatty acids of vegetable oil into saturated or semi saturated state. Trans fatty acids will be produced in this process, which can increase the low-density lipoprotein in human blood, reduce the high-density lipoprotein, induce vascular sclerosis, and increase the risk of heart disease and cerebrovascular accident.
However, total hydrogenation will not produce trans fatty acids. At present, the process of total hydrogenation is very mature. Recently, when revising the composition of food pyramid in the United States, it has been clearly pointed out that attention should be paid to trans fatty acids, and manufacturers are required to indicate the content of trans fatty acids in products.
Therefore, oil manufacturers have developed a new hydrogenation technology. Trans fatty acids will not be produced in the hydrogenation process, and have been used in some products to replace the original fat powder containing trans fatty acids.
