Abstract:
Collagen is not a uniform substance, but is rather a family
of protein. It is a group of naturally occurring proteins found in animals,
especially in the flesh and connective tissues of mammals. For food or nutritional
purpose, collagen is broken down into gelatine which can be broken down further
into hydrolysed collagen. Hydrolysed collagen is a polypeptide composite made
by further hydrolysis of denatured collagen or gelatin and the molecular weights
are within the range approximately 500 to 25000 Da. In hydrolysate, the molecular
mass and the size of the molecules have been deliberately decreased by hydrolysis
part of peptide bonds of the gelatine molecules. This will make the hydrolysed
collagen dissolved in cold water and does not gel anymore but still has surface
active properties. The processes involved in processing hydrolysed collagen
are demineralization, extraction of collagen to gelatine, enzymatic hydrolysis
to obtain hydrolysed collagen, ion exchange, filtration, evaporation, sterilization
and finally drying. In previous study a large number of studies focused on the
enzymatic hydrolysis of collagen or gelatine for the production of bioactive
peptide. However, studies focusing on the process development of hydrolysed
collagen are still limited. This study thus will briefly describe the process
design, market potential, research and development work and potential future
research development for the production of hydrolysed collagen from agriculture
sources such as cattle bones, fish skins and fish scales.
