| titleOfInvention | Process for the preparation of dianhydrides of fructofuranose and their use as nutritive additives |
| abstract | The process consists in reacting a carbohydrate containing at least one fructofuranose unit in which the hydroxyls at C-3, C-4 and C-6 are substituted by a protecting group which is stable in hydrogen fluoride, usually an ester group, with hydrogen fluoride (HF) which is generally diluted in a solvent which is inert or relatively nonreactive towards HF, and extracting the reaction product with dichloromethane. The predominant component hexa-O-acetyl- alpha -D-fructofuranose- beta -D-fructofuranose 1,2':2,1'-dianhydride can be separated at this stage from its isomer, hexa-O-acetyl- beta , beta -difructofuranose dianhydride. Deacetylation of the predominant component, or of the entire mixture of carbohydrates resulting from the reaction, results in compounds exhibiting a pleasant sweet taste, which can be employed in foodstuffs as noncariogenic sweeteners of low calorific value. |
