Study on stability of feed additive lysozyme dimer.

The experiment was to study the stability of feed additive lysozyme dimer in influencing factors and accelerated test, determined the validity period of the product through long-term test. Three batches of lysozyme dimer samples were taken for influencing factor test (high temperature test, high humidity test and light test), accelerated test and long-term test, the moisture, dimer content and enzyme activity of lysozyme dimer were detected as inspection indicators. The results showed that the lysozyme dimer was relatively stable in the influence factor test, accelerated test and long-term test. The validity period of the product was preliminarily determined to be 12 months after the validity period prediction analysis. The experiment indicates that lysozyme dimer is relatively stable. The product can be packed in compound paper bags and stored in dry and ventilated places. [ABSTRACT FROM AUTHOR]
