摘要:
Fifty samples of tomato fruit have been analysed for sugars using a reliable but laborious volumetric method and the results compared with those obtained both by a rapid automated colorimetric procedure employing the Technicon AutoAnalyzer and by a gas Chromatographic (GLC) technique. Using cleared fruit extracts, the overall mean results for the volumetric and automated methods were not significantly different. Automated analysis of uncleared extracts gave only slightly lower results and in view of its speed this method is recommended for the rapid routine analysis of tomato fruit. The GLC procedure gave results some 4% lower than those for cleared extracts by the other methods, but this technique has the advantage that the concentrations of the individual sugars (glucose and fructose) are readily obtained if required.
