Pure maple syrup is a 100% natural food, processed by heat concentration of pure maple sap. This sap is a sterile, clear liquid, which provides the trees with water and nutrients prior to the buds and leaves opening in the spring. In the boiling, concentrating, and filtering processes, all the nutrients remain in the syrup. There are some quantitative differences in maple syrup's nutritive composition due to metabolic and environmental differences among maple trees.
Sugars: Sugars are an important source of energy. The main sugar in pure Maple syrup is sucrose. The darker grades, especially Grade B syrup, contain small and variable amounts of fructose and glucose. In order of sweetness, sucrose is less sweet than fructose, and sweeter than glucose.
Minerals: Minerals have specific and nonspecific nutritional functions in the body's metabolism. In pure filtered maple syrup the main minerals present are: calcium, potassium, manganese, magnesium, phosphorus, and iron.
Vitamins: Vitamins are essential to maintain health; they cannot be manufactured by the body (except Vitamin D) so they must be acquired through food or taken separately. In pure maple syrup trace amounts of vitamins are present, mainly B2 (Riboflavin), B5 (Pantothenic Acid), B6 (Pyridoxine), PP (Niacin, B1), Biotin, and Folic Acid.
Amino Acids: Amino Acids are the building blocks of the proteins. In pure maple syrup many amino acids are present in trace amounts.
Total Solids: The total solid's in pure maple syrup amount to 66.5%, with the remaining 33.5% consisting of water. The table below represents the main elements within the total solids.
