Post-harvest deterioration in quality of sugarcane.

Juice composition was studied during field storage of topped sugarcane (cv. Co.J.64) in piles exposed to the sun during hot (35-40 deg C) dry weather. During 12 days' storage: total soluble solids content (hydrometer Brix) increased from 21.4 to 24.0%; polarimetric sucrose content decreased from 19.5 to 14.6%, while reducing sugars content increased from 0.1 to 3.5%; starch content decreased from 169 to 28 mg/ml; total activity (in nmol sucrose/min per ml juice) of acid invertase increased from 10.2 to 68.4, and its specific activity (nmol sucrose/min per mg protein) increased from 34.7 to 123.2; total activity of neutral invertase increased from 20.5 to 80.2, and its specific activity from 69.7 to 144.4. Estimated sucrose recovery % cane (formula given) decreased from 13.7 to 7.9.
