A wide variety of cleaning techniques are currently used in the maple industry, including rinsing the system with pressurized air and water, or attempts to sanitize with chemical solutions such as peroxide, bleach, or alcohol. However, the effectiveness of these cleaning techniques in reducing microbial populations and increasing annual sap yield is often questionable.
Gravity tubing systems are widely used in many small to mid-sized operations throughout the maple region. This article summarizes the past 3 years of my research on gravity tubing, or tubing without a vacuum pump.
During the 2011 maple sap season a variety of research trials were conducted at the Arnot Forest of Cornell University and in the woods of a number of cooperators both with vacuum and gravity systems. Research conducted over the last five years has shown that significant increases in sap yield can be obtained by keeping the tap hole from contamination by bacteria and yeast.
While you may think that sap pricing should be relatively simple and easy to understand, there are actually many factors that can and should affect sap prices. This article presents a new method for pricing sap and explains how it differs from the traditional pricing guidelines that have been posted annually in the Digest.
Although a number of factors affect maple sap flow in vacuum tubing systems, it has become increasingly apparent that sap yields are largely a function of two major influences: vacuum level at the taphole and taphole and tubing sanitation.
This report summarizes the results from a survey to document respondent’s experience of changes within maple syrup operations and sugar maple (acer saccharum) ecosystems, including potential changes to regulations, technologies and climate.
An increasing number of maple syrup samples containing floating masses or surface mold have arrived at the University of Maine Cooperative Extension. Conventional practices have been to discard obvious mold growths, reboil and consume the syrup. This practice may be risky, especially with the increasing number of food borne illness outbreaks with other food products.
Root starch has been used to estimate tree vigor and health with some success. A visual method of starch determination similar to that already used for roots has been undertaken for twigs. If successful, this method would simplify the process of assessing overall tree health and vigor in sugar maple trees.
In mid-April 2010, an invitation to participate in a survey was sent to subscribers of two maple forums. The survey was designed to get some basic information about the operations of the respondents, to describe sanitation practices (changing tubing, spouts, etc.) and to get feedback from users about the Leader Check-valve adapter.
Feedback received from early users of Leader check-valve adapters, developed by the UVM Proctor Maple Research Center.
