3 Product classification
According to the form, the product is divided into two dosage forms: solid enzyme and liquid enzyme. 4 Technical requirements
4.1 Appearance requirements
4.1.1 Solid enzymes are irregular spherical or short rod-shaped particles without agglomeration. Easily soluble in water. Turbidity caused by non-enzyme components does not affect the activity of the enzyme in the solution.
Superior products are white to light gray particles, and the particles are coated with a layer of material. The first-class products are made by filtering out the fermentation residue. The first-class products and qualified products are gray particles, and can also be colored particles, but the pigments used for coloring must not contaminate the fabric.
4.1.2 Liquid enzymes are brown and can be completely miscible with water. 4.2 Physical and chemical requirements
Physical and chemical requirements shall comply with the requirements in Table 1.
