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.
University of Rhode Island researcher Navindra Seeram, who specializes in medicinal plant research, has found more than 20 compounds in maple syrup from Canada that have been linked to human health, 13 of which are newly discovered in maple syrup. In addition, eight of the compounds have been found in the Acer (maple) family for the first time.
This research was designed to examine age-related losses in sap yield in tubing systems operated under vacuum, and to explore different strategies to reduce tubing microbial contamination induced sap yield losses.
Typically, production is measured in terms of the number of gallons produced. In order to evaluate the effects of season length of maple syrup production I propose an alternative measure of seasonal maple syrup production, “Yield-per-Tap/Day.”
I have been using the bubbler now for six years. I have found that the bubbler allows me to boil as hard as I want without using any defoamer. Pumping natural clean air into the pans is better than adding defoamer of any kind to make a good tasting and pure product.
