Abstract

Disinfection and molecular weight changes by electron beam irradiation has been examined. Before radiation, the viscosity of oven-dried HA decreased about 30% but the viscosity of vacuum-dried HA did not decrease. The number of viable cell depends on the relative humidity(RH). The cell number decreased about 30% in RH 0% and about 10% in RH 100%. After radiation, the decrease in the molecular weight of the hyaluronic acid was larger in the RH=0% than in the RH=100% and was larger in the vacuum-dried HA than in the oven-dried HA. The extent of disinfection were similar for all form.
