In addition, the Hong Kong Consumers Association also tested the actual contents of energy, nutrients and DHA in milk powder. Among them, the actual content of nutrients in milk powder is lower than the labeled content of milk powder, and some even lower than 40%. Although these problems are not very prominent, because it is baby milk powder, the detection of carcinogens and the exaggerated labeling of nutrients have given consumers a sap.
Chloropropanediol was detected in 15 milk powder, and one of them exceeded the prescribed upper limit. As a pollutant in food processing, chloropropanediol has the greatest harm to kidney function and male reproductive capacity.
In addition to milk powder, when making chemical soy sauce, when hydrochloric acid hydrolyzes protein in soybean into amino acids, it also decomposes oil into fatty acids and glycerol, and glycerol reacts with hydrochloric acid to produce chloropropanediol.
In this test, the highest content is "Bellamy's organic" milk powder from Australia, reaching 0/20 micrograms per kilogram/kloc.
The common name of epoxypropanol is glycidyl, which is found in all the 9 milk powders tested this time. It is usually stored in oil as glycidyl ester. After ingesting into human body, glycidyl ester is converted into epoxypropanol during digestion. In food processing, refined vegetable oil at high temperature (above 200 degrees) will form glycidyl ester.
The International Agency for Research on Cancer lists epoxypropanol as a class 2A carcinogen. The Joint Expert Committee on Food Additives of FAO and WHO advises people to reduce their intake as little as possible. However, the expert Committee has not formulated detailed upper limit standards for this purpose.
