FIELD: analytical methods. SUBSTANCE: when determining invert glucose and fructose in saccharose, raw, treacle, syrups, molasses, honey, and other sugar solutions, sample of substance is preliminarily treated with potassium or sodium hydroxide at molar ratio of invert sugar to alkali metal hydroxide between 1:3 and 1:50. Sample is then thermostatically controlled under specified conditions and photometered at 400 nm. EFFECT: accelerated and simplified analysis without use of expensive reagents and complex equipment. 2 cl, 1 dwg, 2 tbl
