Abstract: | The sorption of a mixture ofn-hexanol,n-octanol, andn-hexyl andn-octyl acetates from aqueous solutions by corn starch cryotextures was studied using capillary gas chromatography at different
initial concentrations of the sorbates (1–25 mmol L−1) and corn starch (2–6%). The amounts of compounds sorbed by cryotextures are proportional to the increase in their concentration
in the initial sol and the length of the alkyl substituent. Linear equations describing the concentration dependence were
proposed. The sorption ofn-hexanol from a mixture of substances containingn-octanol increases as compared to that from the individual alcohol. It was shown that the degree of sorption of aroma by cryotextures
was independent of the content of starch in the initial sol.
