Abstract:
Maple sap and syrups in eastern Canada were analyzed for pH, total solids, and the heavy metals Cu, Fe, Pb, and Zn. The levels of heavy metals found were within the range normally contained in food and water samples except for Pb. The concentration factor found in reducing sap to syrup did not reflect the same concentration change for the measured parameters. This indicates removal or conversion of heavy metals and organic acids with the sugar sands. There was no statistical difference among provinces with respect to the heavy metal, pH, and total solids content of sap. The only significant difference in syrup occurred with Cu and this appeared to be the result of the processing procedure. As the season progressed, the Cu, Pb, pH, and total solids content of the sap decreased while Zn increased and Fe showed little change. Syrups reflected a similar change. Statistical differences occurred in sap composition among sites within each province.
