Darkening of Maple Syrup in Uncoated and XL-Coated Plastic Containers

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.

Determining Shelf Life and Consumer Acceptability of Processed Maple Sap Beverages for Small Businesses

Consumer interest in local products and functional beverages has increased markedly in recent years. Several beverages composed primarily of maple sap are currently available in the marketplace. These products are sold at ambient temperature, and are considered shelf stable. Prior investigation has demonstrated the need for specialized processing equipment in order to achieve shelf stability of maple sap beverages. The current study investigated the feasibility of producing a refrigerated beverage without the use of commercial processing equipment for small businesses.

Developing your Maple Marketing Plan for wholesale and bulk sales

The development of a marketing plan allows the maple producer to evaluate options to determine the most livable and profitable marketing options for selling my maple products in the wholesale and bulk market. The finished plan then allows the producer to focus efforts on what has been decided are the most livable and profitable ways of marketing for the business. For many maple producers who are most in love with maple production the question seems to be ÒNow that IÕve made maple syrup what is the best way for me to sell it?Ó The approach used in developing the marketing plan here is that of asking and evaluating some basic marketing questions will lead to assembling a reasona-ble marketing plan.

Development and Testing of the Check-Valve Spout Adapter

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.

Differential impacts of calcium and aluminum treatments on sugar maple and American beech growth dynamics

Acid deposition induced losses of calcium (Ca) from northeastern forests have had negative effects on forest health for decades, including the mobilization of potentially phytotoxic aluminum (Al) from soils. To evaluate the impact of changes in Ca and Al availability on sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.) growth and forest composition following a major ice storm in 1998, we measured xylem annual increment, foliar cation concentrations, American beech root sprouting, and tree mortality at the Hubbard Brook Experimental Forest (Thornton, New Hampshire) in control plots and in plots amended with Ca or Al (treated plots) beginning in 1995.
