Opinion: Cysteine/Gelatin manufacturing from a Halal Perspective

Abstract: Cysteine manufacturing from a Halal perspective

This powerpoint sheds the light on the Halal status of Cysteine which is extracted from human or animal sources and produced by using biotechnology.

Cysteine is one of the 20 natural amino acids and is the only one that contains a sulfhydryl group (– SH) in the side chain. This is highly chemically reactive and forms disulfide bridges, which lend proteins much of their stability.
Cysteine is a natural amino acid that is widely used in the pharmaceutical, cosmetics, and food sectors. One of the largest applications is the production of various flavors. For example, reacting cysteine with sugars in a Maillard reaction yields meat flavors.
It is also used as a processing auxiliary for breaking down gluten for bakery goods, as a radical scavenger in cosmetics, and as an expectorant in cough medicines.
It is interesting to note that currently the cheapest source of material from which food grade Cysteine may be purified in high yield is by hydrolysis of molecules in human hair. Other sources include feathers and pig bristles. Recently Cysteine is produced through microbial bioconversion and fermentation.
