Actual yields in many maple operations are often lower than those achievable under optimum conditions. Dr. Abby van den Berg, Research Associate Professor with UVM’s Department of Plant Biology and Proctor Maple Research Center, presents practices to narrow this gap, from tree to sugarhouse.
Most people recognize good tasting syrup and many can pick out when syrup tastes off, but occasionally there is a flavor that is not easily identified. Mark Isselhardt, UVM Extension, and Henry Mackres, retired Vermont Chief of Consumer Protection, discuss syrup flavors (and off-flavors) and sample syrup sent in advance of the session for diagnoses.

Processing maple syrup into value-added products can increase product diversity, sales and producer profits. When considering the variety of potential value-added products, such as salad dressings, coated nuts, seasoning products, and sauces, it is important to evaluate the ingredients for their allergen risk potential and add the proper allergen statements to food product labels. This will ensure that you produce quality products and protect potentially susceptible consumers.
The Cornell Maple Program has developed a new, user-friendly tool to calculate how much of each syrup you would need to blend. This calculator will only help sugarmakers using digital light meters that give the percentage of light transmittance (%Tc) through your syrup.
Cottage food laws vary considerably from state to state, and are generally intended to be a way for small farmers and food processors to establish small businesses offering value-added food products. Some states require food producers to pay a fee, obtain a permit or license, or register with the town, county or state. Periodic health inspections of home kitchens and even product testing may also be required depending on location.

Although several previous studies have examined syrup darkening in different retail containers, packers and producers sometimes question the effectiveness of an oxygen-barrier in reducing the rate of color change. Two studies were performed by the University of Vermont (UVM) Proctor Maple Research Center (PMRC) in 2018 and 2019 to compare the rate of color (LT) change in maple syrup in uncoated and XL-coated retail plastic containers.
A simple colorimetric test detects off-flavour profiles ofmaple syrups inminutes, which are detectable by the naked eye. As flavour profiles are due to complex mixtures of molecules, the test uses nonspecific interactions for analysing the aggregation and color change of Au nanoparticles (AuNPs) induced by the different organic molecules contained in off-flavour maple syrup. The test was optimal with 13 nm citrate-capped AuNPs reacting 1 : 1 with pure maple syrup diluted 10 times. Under these conditions, normal flavour maple syrups did not react and the solution remained red, while off-flavoured maple syrups aggregated the AuNPs and the solution turned blue. Different classes of molecules were then tested to evaluate the types of compounds typically found in maple syrups reacting in the test, showing that sulfur- and amine-containing amino acids and aromatic amines caused aggregation of the AuNPs. The test was validated with 1818 maple syrup samples from the 2018 harvest in Quebec and 98% of the off-flavoured maple syrups were positively identified against the standard taste test. Preliminary tests were performed on site in maple sugar shacks to validate the applicability of the test on the production site.
