Monosodyum Glutamat (MSG)

Detailed information

What it is & how it is made

A flavour enhancer (umami) that is the sodium salt of glutamic acid. Industrially it is produced by sugar or starch fermentation (microbial); its source is usually plant-based.

Where it is used

Widely used as a taste intensifier in instant soup, crisps, stock cubes, sauces, ready meals and snacks.

Health note

Its health effects have long been debated; although scientific bodies consider it safe at ordinary levels, sensitivity such as headache is reported in some people. Some regard it with caution from the standpoint of the 'tayyib' principle.

Halal assessment

Its production is usually based on plant fermentation and it contains no animal matter; in that respect no halal obstacle may be seen. However, because the fermentation medium and the purification additives are not always transparent and a halal certificate is generally absent, no definitive ruling has been given and it has been left as doubtful. For definitive information, the manufacturer's certificate should be consulted.
