Sugar extract
This invention relates to novel extracts from sugar cane and sugar beet molasses and the characterization of those extracts. The extracts are enriched in hydrophobic compounds including polyphenols, in levels 5 to 10 fold higher than found in molasses itself. Methods for extracting the extract are also described, together with new uses for the extracts as food ingredients, food modifiers and therapeutic substances.
