Techniques to manage spout and dropline sanitation in 5/16″ vacuum tubing systems for high yield maple production.
Identifying an Effective Defoamer for Certified Organic Maple Production
The combination of potential crop losses from foam-related incidents, reductions in crop value due to off-flavors, and ultimately the many adverse effects of such a large proportion of organic syrup with off-flavors potentially being sold to consumers, underscore the need to identify or develop a certified organic defoamer for maple production that is both more effective at controlling foam than the culinary oils that are currently used, and which results in no off-flavors when used in the quantities necessary to adequately control foam. Thus, the overall objective of this project was to identify a certified organic defoamer that met these criteria.

Sanitation, Clogging, or Both: A Comparison Study of 3/16″ and 5/16″ Maple Tubing
It is well recognized that microbial contamination of tubing systems can result in a substantial loss in sap yield if untreated. Over a decade of research and maple industry experience has produced a range of possible strategies to address sanitation-related issues in 5/16Ó tubing systems (Perkins et. al. 2019). Although rapidly adopted by many maple producers, due to the relatively short time period in which it has been in widespread use, there is far less understanding of sanitation in 3/16Ó tubing systems (Wilmot 2018). To address this knowledge deficit, we conducted a multi-year study at the UVM Proctor Maple Research Center to examine sanitation-related losses in 3/16Ó tubing systems to determine which approach(es) might best mitigate sap losses due to sanitation.

A Decade of Spout and Tubing Sanitation Research Summarized
More then a decade ago there was a renewed realization that microbial contamination of maple sap collection systems was having a significant detrimental impact on sap yields. Several research studies to investigate ways to improve sap yields from tubing systems were undertaken at both the University of Vermont Proctor Maple Research Center (Underhill, VT) and at the Cornell University Arnot Forest (Van Etten, NY) starting at about the same time and proceeded both as independent and joint projects from 2009-2018. The results of many of these studies have been reported in the past in numerous individual publications and presentations. This article seeks to combine and present this extensive body of work into a single, comprehensive, but concise summary of our results.
