[Sorption by cornstarch of components of a mixture of volatile organic substances from aqueous solutions].

Effects of the composition of a mixture of organic substances on the binding of individual components in aqueous dispersions of native and gelatinized cornstarches with different contents of amylose was studied by capillary gas chromatography. Sorption was more active when alcohols were exposed to cornstarch as mixtures rather than individual compounds. In a multiple-component mixture, compounds belonging to distinct classes competed with each other for binding sites. Odorant sorption by aqueous starch dispersions was more sensitive to the composition of the mixture and the nature of starch when studied in aqueous dispersions of native starches (compared to those of gelatinized starches).
