Abstract

The invention relates to the field of biological enzyme compositions and particularly discloses a granule based on a biological enzyme composition, as well as a preparation method and an application thereof. The biological enzyme composition is composed of a core part and a coating coated on the core part, wherein the core part and the coating are composed of the following raw materials by weight percentage. By adopting the granule based on a biological enzyme composition, the enzyme or the enzymatic composition is encapsulated in the core part, so that the prepared granule of the composition is strong in dirt-removing power and good in solubility and is particularly suitable for the washing product. The materials used in the invention are environment-friendly, harmless and easily degradable materials, the activity of the enzyme cannot be damaged and the high activity of the enzyme in the granule can be kept for a long time.

Description

technical field [0001] The invention relates to the field of biological enzyme composition, in particular to a granule based on the biological enzyme composition and its preparation method and application. Background technique [0002] Biological enzyme preparation is a raw material that is easy to use, green and environmentally friendly, and has good biodegradability. Specific catalytic properties and mild reaction conditions make biological enzyme preparations more and more used and valued in the industry. The application of biological enzyme preparations in detergents is becoming more and more extensive, and the amount of use in detergents is also increasing because of its low-carbon, environmental protection and high-efficiency characteristics. The proportion of detergents containing biological enzyme preparations in the entire detergent industry is increasing day by day. For example, the proportion of detergents containing biological enzyme preparations in Europe and A...
