Assessment of the Flavor of Syrup Produced with High-Brix RO Systems

Concentrating sap with reverse osmosis (RO) substantially increases the efficiency and profitability of processing maple sap into syrup by reducing the amount of fuel and time required to complete concentration to syrup density in the evaporator, with gains proportional to the level of sap pre-concentration. Because most flavor development in maple syrup occurs through nonenzymatic browning reactions as sap is processed with heat in the evaporator, it has often been speculated that reduced evaporator processing time resulting from the use of RO might also result in perceptible impacts on syrup flavor. However, a series of controlled experiments conducted at the University of Vermont Proctor Maple Research Center using the same sap processed to different levels with RO determined that concentrating sap up to 21.5% prior to boiling in standard maple evaporators had no substantive effects on syrup composition or flavor.

Boiling Clean With Air

I have been using the bubbler now for six years. I have found that the bubbler allows me to boil as hard as I want without using any defoamer. Pumping natural clean air into the pans is better than adding defoamer of any kind to make a good tasting and pure product.

Chemical and microbial characterization of ropy maple sap and syrup

Ropiness of maple syrup is a phenomenon that can occur several times in the season. The alteration known as ÒropinessÓ is characterized by a viscous, thick, slimy/jelly-like texture which, although not noticeably altering the taste, renders the product unpleasant in terms of mouthfeel. The aim of this study was to estimate the economic impact of production of ropy maple syrup in the region of Quebec, to more deeply identify and characterize bacteria associated to this type of quality defect, and to study the composition of Polysaccharides found in stringy maple syrup.

Chemical composition of five standard grades of pure maple syrup

The objective of this study was to characterize the chemical composition of the five maple syrup grades, including their pH, conductivity, mineral and carbohydrate contents. In general, quantification of the range of chemical composition for each standard maple syrup grade will strengthen the existing knowledge of maple syrup chemistry.

Chemical Composition of Scale in Maple Syrup Evaporators

The goal of this work was to investigate the chemical composition of the scale that is deposited on maple evaporator surfaces during sap processing. Knowing the chemical composition of scale produced in modern equipment and how it compares to previously published values for loose sugar sand may aid in understanding how best to remove these unwanted deposits.

Climate Change and the New England Forest

In the next one hundred years New England’s cooler regions may no longer promote the growth of sugar maples, which are well adapted to the region’s current climate. The change in climate will support species that now grow to the south of New England and in lower elevations, especially oaks and southern pines. Additionally, there will be the threat of non-native species, both insect pests and invasive plant species which may take over the forests.
