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.
