Monoammonium Phosphate (MAP), NH4H2PO4 (Purified), is a white granular crystal that is easily soluble in water, slightly soluble in alcohol, and insoluble in ketone. Food grade Monoammonium Phosphate (MAP) is mainly used as a fermentation and nourishment agent. Though it’s considered safe, some are convinced it has potentially dangerous health effects.
What Is Monoammonium Phosphate?
Monoammonium Phosphate (Food Grade) is used as a acidulant for sharping the taste of acidic foods. Applications include tomatoes, lemons, oranges, apples, cheese and yogurt.
Possible Side Effects of Monoammonium Phosphate
Monoammonium Phosphate is generally considered a safe ingredient. The side effects may cause upper respiratory tract irritation. Acute Ingestion: May cause abdominal cramps, nausea, vomiting, diarrhea.
GRAS Affirmation: Yes
Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements.

Special Populations Precaution
There is a lot of concern about diet and nutrition for these population, like Newborns, children, pregnant, sensitive to Monoammonium Phosphate populations. Better consult to your doctor if you would like to intake Monoammonium Phosphate.
