High temperature resistance diaphragm-controlled phytase pellets and preparation method thereof

Abstract

The invention discloses a high temperature resistance diaphragm-controlled phytase pellets and a preparation method thereof. The high temperature resistance diaphragm-controlled phytase pellet is composed of phytase pellets and coating materials which are coated on the outer layer and has high temperature resistance action, and the weight ratio is 20-80:80-20. The diaphragm-controlled phytase pellets prepared by the coating method has favorable liquidity and dispersibility and strong capability of resisting damp and heat, avoids enzyme activity loss in the feed processing, transportation and storage processes, and effectively improves the phytase heat stability and storage stability.

Description

High temperature resistant film-controlled phytase pellets and preparation method thereof technical field The invention relates to a preparation method of a feed additive, in particular to a preparation method of a high-temperature resistant film-controlled phytase pellet. Background technique Mineral phosphorus is one of the essential nutrients for animal growth and production. It is not only an important structural component of the body, but also widely participates in many important physiological and biochemical processes of the body. Livestock must obtain sufficient phosphorus from feed in order to maintain normal life and production activities. The proportion of plant-based feed in monogastric animal feed is very large, and 60-80% of the phosphorus is in the form of phytate phosphorus. Because monogastric animals lack the enzymes required to decompose phytate phosphorus, they cannot fully digest and utilize it. Therefore, expensive inorganic phosphate must be added t...

Problems solved by technology

However, the stress resistance of some current phytase products, especially the thermal stability, cannot meet the requirements of feed and feed processing, which has become one of the important limiting factors restricting the popularization and application of phytase.
