Comparing E333II - Dicalcium citrate vs E1101 - Protease

What is a protease?

A protease (E1101) is an enzyme that catalyzes proteolysis—cutting peptide bonds to break proteins into smaller fragments.

What does protease do?

In foods, E1101 proteases break down proteins to modify texture and processing—for example tenderizing meat, improving dough handling, clarifying beer, and creating protein hydrolysates.

What does protease break down?

Proteases break down proteins into peptides and amino acids by hydrolyzing peptide bonds.

What is a protease inhibitor?

A protease inhibitor is a substance that blocks protease activity; some occur naturally in foods (e.g., in legumes), and others are used as drugs to inhibit specific proteases.

Where is protease produced?

Proteases are made by animals, plants, and microorganisms; for food use (E1101) they are commonly produced by microbial fermentation (e.g., Aspergillus or Bacillus) or extracted from sources like papaya or pineapple, and less often from animal tissues.
