Effect of Adjusting the Water Activity to 0.95 with Different Solutes on the Kinetics of Thiamin Loss in a Model System
The kinetics of thiamin degradation in a model system of pH 6.0 and water activity (aw) 0.95 controlled with NaCl, KC1, glycerol or Na2SO4, was studied. The type of solute used to adjust aw, had a dramatic influence on the rate of degradation of thiamin. The loss of vitamin increased in the followin...
