Trans fatty acids come from natural or industrial production. Natural sources are mainly ruminants, such as cattle, sheep and other meat, fat, milk and dairy products, the content is very low. The main sources of industrial production are hydrogenation and refining of vegetable oil and artificial trans fatty acids produced during food frying and frying. Studies have found that artificial trans fatty acids seem to have adverse cardiovascular effects. Excessive intake of trans fatty acids may lead to the increase of total cholesterol and the significant decrease of high-density lipoprotein, which may increase the incidence of atherosclerosis and coronary heart disease, and other diseases such as diabetes, hypertension and cancer may also be related to this. In China’s national food safety standards, hydrogenated oil should not be used in infant formula food and auxiliary food.
The common expressions of trans fatty acids in the label ingredient list include the following: hydrogenated vegetable oil, partially hydrogenated vegetable oil, hydrogenated palm oil, hydrogenated soybean oil, hydrogenated fat, partially hydrogenated fat, shortening, margarine, margarine, cocoa butter substitute, vegetable fat powder, etc.
“General requirements for children’s snacks” is a group standard rather than a national standard, which is not compulsory. Therefore, parents should pay more attention to whether there are trans fatty acids in the packaged food for children.
