Century Dictionary and Cyclopedia

  1. n. A crystalline sugar, C18H32O16 + 5H2O, found in Australian manna from different species of Eucalyptus, sugar-beets, cotton-seed, and barley. It has no sweet taste. When heated with dilute sulphuric acid it first yields fructose and melibiose, then the latter is broken down into glucose and galactose. It is dextrorotatory and ferments only partly with yeast. Also called melitose, gossypose, and melitriose. Inactive raffinase is found in sugar-cane and in beet-molasses. It does not crystallize.
