Probiotic Enzyme Powder Freeze Dryer

Probiotic Enzyme Powder Freeze Dryer

Enzymes are products containing specific biologically active ingredients obtained by microbial fermentation using animals, plants, fungi, etc. as raw materials. At present, enzyme foods on the market mainly include liquid, paste, powder, tablet, and other forms. In recent years, enzyme powder has become the most promising enzyme variety due to its easy storage and transportation characteristics. However, the current market products have problems such as "low density and poor activity" that restrict their development. Therefore, the development of enzyme powder with high probiotic content and high active ingredients has become one of the important trends in the development of the industry.

The difference between freeze-drying and spray-drying process advantages of probiotic enzyme powder: At present, the main methods of preparing enzyme powder at home and abroad are: spray-drying, freeze-drying (vacuum freeze-drying), and so on. Among them, the spray drying method has low cost and high efficiency, but due to the need to undergo high temperature, the bacterial cell survival rate is low, and it is more suitable for liquid samples with low heat sensitivity. At present, some powdered enzyme products on the market are made by spray drying, and the products do not contain or contain a low amount of active probiotics, which cannot meet the requirements of probiotic products for the number of viable bacteria (106CFU/g or 106CFU/mL). The product obtained by the probiotic enzyme powder freeze-drying machine has more viable bacteria and less loss of activity and is more convenient in the process of transportation and storage. The disadvantage is that its cost is higher than that of the spray drying process.
