Use of Piezosensors for Determining the Composition of the Equilibrium Gas Phase of Aqueous Protein Solutions

摘要

Possibility of using modified piezosensors to determine the composition of multicomponent gas mixtures was studied. The sorption conditions of readily volatile components of aqueous protein solutions on modifier films of varied nature for piezoquartz resonators were examined and optimized. A set of methods for determining aroma-forming components of complex mixtures was developed. The possibility of using the methods developed for determining the nature of aroma-forming additives to milk drinks was demonstrated.
