Effects Of The Use Of Paraformaldehyde (PFA) Sterilising Pellets On Sugar Maple Health: A Review
Higher and wider discoloration, compartmentalisation and decay in maple wood by the use of the PFA pellet restricts the healthy sapwood areas and diminishes translocation of sap and nutrients. Furthermore, technological advances for better sanitation in sap collection and storage presently in use by the maple industry, tested by research to be safe for maple tree health and syrup quality, have made the use of the PFA pellet unnecessary.
“Salty” Syrup from Roadside Sugar Maples in Decline
We had two objectives in the study of sugar maples which showed signs of decline and stress on a roadside where deicing salt was used in the winter. One goal was to determine if tree stress is related to the levels offsodium and chloride in their sap and in the groundwater and soil around their roots; and, if so, to develop methodology approved by the Association of Official Analytical Chemists (AOAC) that would allow any laboratory to use a standard method to assess maple tree decline due to sodium and chloride effect. The second goal was to evaluate the quality of the syrup processed from sap aseptically collected from maples in decline. We are updating here the later objective of the project that is of interest to the sugar maple producers.
Treatment of Sugar Maple Sap with In-Line Ultraviolet Light
We initiated a controlled test of the effect of in-line UV light on the microorganisms in free-flowing sugar maple sap that had not been treated by PFA pellets at the taphole. We also wanted to test the effect of temperature-controlled sap storage for five intervals up to 7 days (167 h) prior to processing to syrup.

Sap Preheaters: Efficient Maple Syrup Processing
In 1974 the Vermont Experiment Station, Proctor Maple research team, and the Northeastern Forest Experiment Economics Research Unit at Burlington, VT, launched an intensive 4-year processing research program. This program was designed to accomplish two major goals: (1) increase the efficiency of the conventional open-pan evaporator system from approximately 65 percent to approximately 80 percent; and (2) evaluate new evaporator systems for processing maple syrup products. As an initial part of the first research objective, the energy balance of the conventional open-pan evaporator has been completed. Also, design and laboratory and field testing of a sap preheater system has been completed.
Effects of Moisture and Fertilizers on Sugar Maple Seedling Growth
Two ways to help satisfy the need for more high-quality sugar maple trees (Acer saccharum Marsh.) are by establishing plantations and by supplementing natural regeneration. To gain basic knowledge of seedling requirements for this species we studied the effects of soil moisture and nutrient levels on the growth of sugar maple seedlings in their first 3 years.
Variation in Sugar Content of Maple Sap
A knowledge of variation in sugar content is significant in any program aiming at improvement of existing maple stands. Certainly a factor which cannot be overlooked in making thinning recommendations for a producing stand is the sap quality of the maple trees under consideration. Respective yields, which are related to sugar content of sap as well as to amount of sap produced, must be taken into account.
