China's top food watchdog said the content of trans fat in homemade baby formula abides by national and international standards, contrary to a media report claiming that some milk powder contains too much of the substance.

"Test results showed the value of trans-fatty acids in domestic baby formula products was 0.019 to 0.574 grams per 100 grams of milk powder, which conforms to national and international standards," said a notice that the China Food and Drug Administration posted on its website on Tuesday.

Tests of fatty acids and trans-fatty acids were performed on 10,187 samples of baby formula products manufactured on the Chinese mainland in recent years, it said.
