Sorption of aliphatic alcohols, acetates, and their mixtures by corn starch cryotextures depending on concentrations of sorbates and starch in initial sols

The sorption of a mixture of n-hexanol, n-octanol, and n-hexyl and n-octyl acetates from aqueous solutions by corn starch cryotextures was studied usi ng capillary gas chromatography at different initial concentrations of the sorbates (1-25 mmol L-1) and corn search (2-6%). The amounts of compounds s orbed by cryotextures are proportional to the increase in their concentrati on in the initial sol and the length of the alkyl substituent. Linear equat ions describing the concentration dependence were proposed. The sorption of n-hexanol from a mixture of substances containing n-octanol increases as c ompared to that from the individual alcohol. It was shown that the degree o f sorption of aroma by cryotextures was independent of the content of starc h in the initial sol.
