People who like to drink milk tea are no stranger to creamers. It is often said that there is no pure milk in the milk tea nowadays, and all of them are made of milk essence. The milk powder contains fat powder, and the fat powder contains trans fatty acid, which is harmful to health. So, are there trans fatty acids in the end of vegetable fat? Can’t trans fatty acids be touched at all?
Milk essence is a kind of substance instead of milk, its main component is vegetable fat powder.
Vegetable fat powder was first used in coffee partner, its main components are plant fat, corn syrup and plant protein.
Fat powder is not equal to trans fatty acid
When it comes to the end of vegetable fat, people will think of trans fatty acids and even equate them with trans fatty acids. In fact, it is not the same as trans fatty acids. The raw material of vegetable fat powder contains hydrogenated vegetable oil.
Hydrogenated vegetable oil is made from vegetable oil through hydrogenation process. Hydrogenation of vegetable oil is an operation to improve food processing performance by hydrogenation on unsaturated bond to increase the melting point of oil. Liquid vegetable oil is not good in crisp effect, but after hydrogenation, it is semi-solid at room temperature, which can meet the requirements of technology and taste.
In addition, the chemical properties of hydrogenated vegetable oil are relatively stable, which can extend the shelf life, and the cost is lower than animal fats such as natural cream, so it is widely used in food industry.
If the hydrogenation of vegetable oil is not complete, some double bonds will be converted from natural CIS structure to trans structure, which will produce some trans fatty acids. Therefore, due to the hydrogenation process, there may be trans fatty acids in the plant fat powder, but the vegetable fat powder itself is not trans fatty acid, so it is not accurate to simply regard the fat powder or milk essence as trans fatty acid.
Trans fatty acids can be produced only by incomplete hydrogenation of vegetable oil. If it is completely hydrogenated, trans fatty acids will not be produced, but saturated fat will be produced. Therefore, fully hydrogenated vegetable oils do not contain trans fatty acids.
