The Mean

Abstract Quantitation of oligosaccharide-bound galactose by galactose oxidase treatment of the higher sugar fraction is useful to screen honeys with normal stable carbon isotope ratio values for the presence of beet sugar products. For 23 beet sugar products tested, the mean bound galactose value was 30.1 mg/100 g (as galactose); for 81 honeys, the mean was 3.1 mg/100 g, s = 4.4. Nine percent of the honey samples tested had values in the beet sugar range, so additional testing by other procedures is required for confirmation of adulteration, i.e., samples with 8-80 mg/100 g bound galactose should be further tested.
