Most of the enzymes used to make protein
hydrolysates for applications in biotechnology are obtained from animal, plant and
microbial sources. Recent advances in techniques for the hydrolysis of proteins have
come from studies mainly with proteolytic enzymes from fermentation processes.
The main advantages of enzyme hydrolysis of proteins is that the hydrolysis conditions
are mild and enzymes are more specific enabling the manufacturers to precisely
control the degree of hydrolysis and tailor make products for the end users.
