HWM, high weight molecule; LMW, low weight molecule.
According to the profiles, the high molecular weight aggregates, main
peak, and low molecular weight fragments showed significant changes
(Figure 1). The high molecular weight aggregates and low molecular
weight fragments have an increase tendency, Main peak has an decrease
tendency in light treatment and heat treatment Samples.The main peak of
96-h heat treatments is less than 90%, which has serious safety risks.
