A guide to tasting maple syrup and checking for off-flavors
The use of air injection technology in the maple industry can be defined as: the forced introduction of air through a series of perforated pipes submerged in the boiling sap in the front and /or back pan of a maple syrup evaporator. Several studies conducted in recent years have investigated aspects of the use of air injection technology in the process of maple syrup production.
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.

Higher and wider discoloration, compartmentalisation and decay in maple wood by the use of the PFA pellet restricts the healthy sapwood areas and diminishes translocation of sap and nutrients. Furthermore, technological advances for better sanitation in sap collection and storage presently in use by the maple industry, tested by research to be safe for maple tree health and syrup quality, have made the use of the PFA pellet unnecessary.
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.
The advent of plastic tubing systems to collect sap has eliminated several problems associated with the traditional bucket system. However, plastic tubing systems also present some problems of their own. Sap quality problems arise if the lines sag and the sap lingers within the tubings or the large conduits. In addition, the warming effect of the sun increases the tem perature within the tubing to optimum levels for microbial growth and sap flow may decrease because of “organic buildup” on the internal tubing walls. This buildup is a result of the adhesion of microorganisms to the tubing walls.
