Abstract
Abstract A method of sweetening a substance comprises incorporating therein a mono- or poly- chloro, mono- or poly- deoxy sucrose derivative having chlorine atoms in selected combinations of positions 4,6,1'- and 6'- of the sucrose molecule. The compounds are many times sweeter than sucrose and are formulated as ingestible products, such as foodstuffs and beverages; oral compositions, such as toothpaste and chewing gum; or sweetening compositions, such as tablets, for addition to beverages, etc.
