Metabolism Off-Flavor In Maple Syrup – Part I: Identification of the compound responsible for metabolism off-flavor

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.

In the marketplace today, there are numerous instances where a product that does not contain any real maple syrup conveys in various ways, on its packaging or in its advertising and promotion materials, that it does contain real maple syrup or, even, is real maple syrup. The International Maple Syrup Institute (IMSI) and the North American Maple Syrup Council (NAMSC) believe that such behavior is misleading and deceptive to consumers, be it intentional or not, and should be curtailed, much as with any truth in advertising or labeling issue.
