ABSTRACT:
Disclosed herein is an accelerated method of achieving a desired moisture content or water activity in a standard sample of biomaterial comprising the steps of (a) placing the sample in the headspace of an equilibration chamber; (b) establishing in the headspace an atmosphere of 100% or approximately 0% relative humidity; (c) exposing the sample in the headspace to the atmosphere for a predetermined length of time to achieve the desired moisture content or water activity, this length of time having been predetermined by the use of a previously prepared curve which has been prepared using corresponding samples under the same conditions in the same equilibration chamber; and (d) removing the sample from the chamber at the conclusion of the predetermined length of time when the sample has not reached an equilibrium with the humidity in the atmosphere in the chamber. Apparatus for practicing the method is also disclosed.
