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.

Chloro-substituted sucrose compounds

Sweeteners

Novel sugar acetals such as those of formula ##STR1## where R.sup.a is hydrocarbyl; R.sup.b and R.sup.c are hydrogen or hydrocarbyl; R.sup.3' R.sup.4' and R.sup.6' are hydrogen or R.sup.4' with R.sup.3' or R.sup.6' is ##STR2## are made from 1,4-linked reducing disaccharides by a new exchange acetalation process in which the solvent is omitted. The sugar acetals have free hydroxy groups on the ring which groups can be converted to other substituents, e.g. chlorodeoxy or fatty acid acyl. After deprotection, the corresponding derivative of the initial disaccharide is obtained.
