Food Preservatives

Preservatives are substances that prolong the shelf life of foods by protecting them against deterioration caused by microorganisms. Preservatives are divided into two main groups, that is preservatives available naturally & artificial preservatives of compounds that are chemically synthesized.

Each preservative has a maximum limit that can be consumed so as not to cause adverse health effects. BPOM Regulation No. 36/2013 includes a maximum limit for the use of preservative food additives.

On the other side, to  protect food consumers, the government has also issued a policy in the Peraturan Menteri Kesehatan Nomor: 1168/Menkes/Per/X/1999 for several prohibited food additives, and one of them is non-food preservatives whose use is completely prohibited in food, such as formaldehyde and borax
