NOTE

  • In this subclass, the following terms or expressions are used with the meanings indicated :
    • "sugar" is used in its non-scientific meaning and refers to sucrose, also called "table sugar" or saccharose", a white crystalline disaccharide;
    • "sugar juices" are solutions of sugar, essentially comprising sucrose, which are derived from different plants, e.g. beet, cane or maple;
    • "syrups" are highly concentrated sugar juices.
