Summary
The hydrolysis of disodium-p-nitrophenyl phosphate (catalyzed by alkaline phosphatase) in frozen sugar and maltodextrin solutions was studied, with emphasis on how the rate of hydrolysis could be related to the glass transition temperature. Reaction rates decreased with storage temperature and approached zero at temperatures below -15 deg C. Arrhenius plots of the data were non-linear, and the slopes of the best-fitting lines differed from one solution to another.
