Food-safety note
Permitted as an intense sweetener in Australia and New Zealand under the Food Standards Code (Schedule 15), subject to maximum permitted levels. Aspartame contains phenylalanine, so foods sweetened with it must carry a statement for people with phenylketonuria (PKU); FSANZ and JECFA regard it as safe at permitted levels. (Source: FSANZ; Food Standards Code Schedule 15.)
