The objective of this study was to examine several possible remediation techniques to determine which, if any, was most effective in reducing or removing metabolism off-flavor from maple syrup.
Research on metabolism off-flavor in maple syrup at the University of Vermont Proctor Maple Research and Extension Center (PMREC) had two main objectives. The first was to identify the primary compound(s) responsible for metabolism off-flavor in maple syrup. Once the responsible compound or compounds were identified, measures to reduce or remove the off-flavor from finished maple syrup could be investigated. Thus, the second main objective was to determine whether a technique could be found that maple producers and packers might employ to effectively remediate the flavor, and thereby increase the economic value, of metabolized maple syrup.
We had two objectives in the study of sugar maples which showed signs of decline and stress on a roadside where deicing salt was used in the winter. One goal was to determine if tree stress is related to the levels offsodium and chloride in their sap and in the groundwater and soil around their roots; and, if so, to develop methodology approved by the Association of Official Analytical Chemists (AOAC) that would allow any laboratory to use a standard method to assess maple tree decline due to sodium and chloride effect. The second goal was to evaluate the quality of the syrup processed from sap aseptically collected from maples in decline. We are updating here the later objective of the project that is of interest to the sugar maple producers.
