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.
In 2012 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes. These tests were done at the Cornell Arnot Research Forest.
In 2013 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes that would result. Most of these tests were done at the Cornell Arnot Research Forest.
In 2014 and 2015 the focus of the tubing and taphole sanitation research changed dramatically. Tests conducted in 2013 showed that if the spout and drop line were adequately sanitized sap yield comparable to a new spout and drop could be obtained. With the assistance of a grant from the Northeast Sustainable Agriculture Research and Extension program of the USDA and in cooperation with the Proctor Maple Research Center in Vermont, a variety of spout and drop cleaning and replacement options were tested to determine the extent of sap yield changes.
There are a number of ways to clean tubing systems to avoid microbial contamination of tapholes and sap.
Best practices for cleaning tubing in Canada.
Over the course of one maple sap season in Western New York that started approximately March 8, 2005 and ended April 9, 2005, four maple sap locations were sampled to determine the levels and diversity of microbial populations contained in the different sap samples.
Regardless of the availability and guidance provided, maple producers should clearly understand that the use of isopropyl alcohol in maple tubing systems anywhere in the United States is a violation of federal law.
The objective of this study was to investigate the effects of using acid on the chemical composition and the sensory quality of syrup produced after cleaning.
