Monosodium Glutamate, CAS# 142-47-2, is a sodium salt of glutamic acid manufactured through fermentation, available as white Powder. Monosodium Glutamate is widely used as flavourings. It is widely accepted as safe food additive in many countries with E number E621.
Using of Monosodium Glutamate in large quantity (more than 2.2g/day) could cause significant obesity.
As Monosodium Glutamate is widely known as safe, there is no limit on dosage of intake. However, we still recommend consumers to consult professionals before using large quantity of Monosodium Glutamate for long period.
Special groups refer to newborns, children, pregnant and any other applicable vulnerable groups.
There is no evidence that Monosodium Glutamate could have any negative effects on these vulnerable groups. It should be safe to use Monosodium Glutamate in food for newborns and pregnant. However, we still recommend consumers to consult professionals before using large quantity of Monosodium Glutamate for long period in food for newborns or pregnant.
Generally recognized as safe(GRAS) is a FDA designation that a specific substance or ingredient is generally considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. Monosodium Glutamate is considered safe by FDA according to existing data and granted GRAS status.
