The colorimetric method developed is based on extraction of sugars with 80% ethanol, destruction of interfering reducing sugars with Fehling solution, and reaction of remaining sucrose with anthrone in sulfuric acid at 40 C. Absorbance of the sucrose-anthrone complex is read at 610 nm. and compared with the absorbance of a similarly treated standard sucrose solution. An automated method using a Technicon AutoAnalyzer is also described. Application of the method to determine added sucrose in sweetened wheat- soy blend and sweetened corn-soy-milk for quality assurance and regulatory purposes is described.
