Enzyme products must satisfy three requirements:
-
The enzyme activity must be stable
-
The physical form must be compatible with the intended use
-
The product must be safe to use
These requirements are satisfied by means of the product formulation. The products have many different forms and properties to accommodate the differences in the enzyme protein characteristics and their usage in various industries.
Liquid forms:
Typically an enzyme product contains 1-5% enzyme protein. The enzyme is dissolved in water and stabilizers such as glycerol, salt and sugar.
A more advanced form is the proprietary encapsulated enzyme product that Novozymes has recently developed, which offers improved stability and a delayed-release feature.
Solid forms:
Solid enzyme products are typically
free-flowing powders consisting of particles with a diameter between 0.1 and 1 mm and with an enzyme content in the range of 1-5% enzyme protein.
Novozymes produces several kinds of granulated and immobilized products. The most important is the T-granulate, which is a low-dusting, reinforced core particle coated with a waxy material. The T-granulate is predominantly used in powder detergents. Other types include the BG-granulate, used in enzymes for baking, and the immobilized product Sweetzymer, used in the conversion of glucose to fructose.
