Achieving a consistent and acceptable density level for maple syrup continues to be a challenge for many producers.
Wood chips, wood pellets, and used vegetable oil can all be used to fire properly adapted evaporators. Each has advantages and challenges.
This study examines the effects of summer drought on the composition and profiles of cold-season reserve and soluble carbohydrates in sugar maple (Acer saccharum Marsh.) trees (50-100 years old or-200 years old) in which the crowns were nondamaged or damaged by the 1998 ice storm. The overall cold season reserve carbohydrate profiles in twig wood tissue of drought-stressed (DS) trees and non-drought-stressed (NDS) trees were generally similar, although differences were observed in the amount of reserve carbohydrates in DS and NDS trees. The cold-season level of starch stored in DS trees in early autumn in the wood tissue was about one-third to one-fifth that in NDS trees. The cold season sugar content in the DS trees was significantly greater than can be attributed to degradation of stored starch, only.
The goal of this project was to find alternative ways to reduce microbial contamination of tapholes. One approach we investigated was to use a check-valve to prevent microbial contamination of tapholes by preventing backward movement of sap from the tubing system into the taphole.
In recent years, some maple equipment manufacturers have sold air injection (AI) technology equipment for the production of maple syrup. For purposes of the recent industry review conducted by the International Maple Syrup Institute, air injection technology is defined as the forced introduction of air through a series of perforated pipes submerged in boiling sap in the front and/or back pan of a maple syrup evaporator.
Invasive exotic plants are becoming more prevalent and can have a negative impact on sugarbushes. Maple producers need to know how to identify and eradicate invasives.
A handbook of best management practices for maple producers to help commercial producers identify possible enhancements to their sugaring operations that maintain high standards of cleanliness in all phases of the process, reduce to the lowest extent possible the potential for contamination of the finished product, and achieve the highest possible quality pure maple syrup.
How sap pressure and flow interacts in maple trees during the sugaring season.
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.
