Abstract

Abstract: In this study, a method for detecting inositol in food samples was established based on the relationship between the growth of an inositol-deficient yeast strain and the content of inositol in its culture broth. The inositol-deficient yeast Saccharomyces uvarum CICC 1465 was selected from six yeast strains based on its growth specificity for inositol. When it was employed to determine inositol contents in four kinds of foods, the method showed good precision with relative standard deviation (RSD) less than 10%, recoveries (92.3%-114.3%) and reproducibility (RSD less than 10%), indicating that the developed method can be used for the quantitative determination of inositol in food samples.

Key words: inositol, Saccharomyces, detection
