Abstract: The present invention relates to nutritionally enriched maple syrup, which is enriched in vitamins, and more particularly to nutritionally enriched maple syrup which contains vitamin C in an amount of 50 mg or more based on 100 ml of maple syrup obtained by thermally concentrating a maple sap. The present invention also includes maple syrup enriched in vitamins such as vitamin E and vitamin B1 and other nutrients. According to the present invention, the nutritional value and quality of maple syrup, particularly maple syrup obtained by thermal concentration, can be improved and the range of its use for other foods can be widened. Nutrient enrichment can be carried out by an efficient method suited for industrial scale production. Moreover, the nutritionally enriched maple syrup of the present invention exhibits a well-balanced flavor, and thus it can be widely added to various foods.

Abstract: A composition is disclosed comprising a water-insoluble or slightly water-soluble compound and a branched cyclodextrin-carboxylic acid. The branched cyclodextrin-carboxylic acid significantly increases the water-solubility of the compound. Also disclosed is a method of enhancing water-solubility of the compound.

Abstract: A process for producing a saccharide carboxylic acid or a salt thereof characterized in that a microorganism belonging to the genus Pseudogluconobacter and capable of oxidizing a hydroxymethyl group and/or hemiacetal hydroxyl-associated carbon atom to a carboxyl group, or an artifact derived from the microorganism, is permitted to act on a hydroxymethyl and/or hemiacetal hydroxyl-containing saccharide or saccharide derivative to produce and accumulate the corresponding carboxylic acid and the carboxylic acid so accumulated is harvested and novel saccharide carboxylic acids produced by the above production method, and by the process, from a broad range of saccharides, saccharic acids having carboxyl groups derived from hydroxymethyl and/or hemiacetal OH groups can be produced with high selectivity and in good yield, the resultant saccharide acids are resistant to enzymatic degradation and have improved water solubility, among other characteristics.
