Plastic Tubing and Maple Syrup Quality

Maple syrup made from sap collected using improperly or carelessly installed plastic pipelines varied more in color from day to day, and was more often darker in color, than sap collected from either the property installed pipeline or clean, frequently emptied galvanized buckets. Use of both properly installed tubing and buckets, following recommended procedures, produced light colored syrup of equal quality throughout the entire maple syrup season.

Population dynamics of sugar maple through the southern portion of its range: implications for range migration

The range of sugar maple (Acer saccharum Marsh.) is expected to shift northward in accord with changing climate. However, a pattern of increased sugar maple abundance has been reported from sites throughout the eastern US. The goal of our study was to examine the stability of the sugar maple southern range boundary by analyzing its demography through the southern extent of its distribution. We analyzed changes in sugar maple basal area, relative frequency, relative density, relative importance values, diameter distributions, and the ratio of sapling biomass to total sugar maple biomass at three spatial positions near the southern boundary of the speciesÕ range using forest inventory data from the USDA Forest Service Forest Inventory and Analysis program over a 20 year observation period (1990Ð2010).

Potential Plastic Residues in Maple Sap and Syrup Following Isopropyl Alcohol Sanitation of the Tubing System

In recent years isopropyl alcohol (IPA) sanitation was proposed after the sugar season to significantly reduce the microbial load and start the next sugar season with a sanitized system. This study was conducted to evaluate the potential leaching of chemical compounds found in plastic polymers used in maple sap collection system tubing.

Preventing mould in packed maple syrup

Preventing mould in packed maple syrup can be a challenge. Cold-packing syrup usually guarantees mould will grow in bottled containers and can impart off-flavour in the syrup. Maple researchers at the University of Maine and at Carleton University in Ontario are investigating whether current hot packing recommendations require refinement to preserve quality and prevent mould in syrup.
