| Abstract: | Orange beverage prepared from orange concentrate, sugar, citric acid, ascorbic acid, natural orange oil and water, was stored at 4 °C and at 25 °C in glass bottles and polystyrene cups. Changes of odour and of flavour were correlated with changes of ascorbic acid and dehydroascorbic acid, and with changes of profiles obtained by gas chromatography of chloroform extracts. Chromatographic peaks suitable for the prediction of sensory quality were selected by multiple regression analysis of experimental data. Very close correlations were found for some peaks and their combinations. |
