A kind of antimicrobial spray drying protective agent and its application

Abstract

The invention discloses a bacterial agent spray drying protective agent and application thereof. The main component of the spray drying protective agent used in the present invention is processed bean dregs. The fresh bean dregs are dried, ground and sieved, then added to the fermentation broth, mixed evenly, and then spray-dried. Microorganisms used in the present invention include Bacillus licheniformis (Bacillus licheniformis ), deposit number CGMCC No.1.265; Bacillus subtilis ( Bacillus subtilis ), deposit number CGMCC No.13932; Clostridium butyricum ( Clostridium butyricum ), deposit number CGMCC No.1.5205. The use of treated bean dregs as a spray drying protective agent can increase the number of viable bacteria in the bacterial agent, and the use of bean dregs can reduce waste emissions, protect the environment, turn waste into treasure, and reduce costs.

Description

A kind of bacterial agent spray drying protective agent and its application technical field The present invention relates to spray drying protective agent field, be specifically related to a kind of microbial inoculum spray drying protective agent and application thereof. technical background At present, the preparation of microbial inoculum generally adopts freeze-drying or spray-drying, and wherein the former is used more. freezing Drying, also known as sublimation drying, refers to the transformation of water in the material into ice under low temperature conditions, and the sublimation of ice into steam under higher vacuum conditions. To achieve the purpose of material drying. Freeze drying consumes less heat and can maintain the physical structure and chemical structure of the material to the greatest extent. complete structure. However, freeze-drying has a small amount of single treatment and high cost, so it cannot be widely used. Spray drying is that after...

Problems solved by technology

According to incomplete statistics, the annual production of wet bean dregs in my country is more than 20 million tons, but its utilization rate is extremely low. Most of the bean dregs are directly thrown away as waste, causing environmental pollution and waste of resources.

[0007] At present, bean dregs are more used as raw materials for spray drying, but less commonly used as fungicide spray drying protective agents
