High Brix Syrup Processing & First Two Seasons with Lapierre HyperBrix
Given our extensive research experience on RO processing and flavor, and the appearance of new RO technology that could concentrate to higher levels, a shift toward this new technology seemed appropriate. Therefore after investigating various options, we entered into a partnership with Lapierre Equipment to utilize the new HyperBrix RO system at UVM PMRC. This paper describes some aspects of our first two seasons of use of this equipment. Given the state of the industry, we define Òhigh brixÓ maple sap processing as RO machines capable of producing concentrate at 30¡Brix or higher.
Does Color Matter? Spouts come in variety of hues. Does it affect yield?
In general, it is presumed that any effect of Òspout colorÓ on sap yield arises due to thermal warming of darker-colored spouts during sunny periods. Darker-colored spouts warm faster and the spout temperature can rise considerably above air temperature when hit by the sun compared to lighter-colored spouts. To assess the effect of Òspout colorÓ on sap yield, we conducted a multi-year study at the University of Vermont Proctor Maple Research Center in Underhill, Vermont. Twelve treatment plots were randomly assigned a different spout type, with one mainline and releaser for each plot.
3/16 inch Tubing with Check Valves Trial
In a normal sap flow event, trees exude sap during the above freezing period and replenish that lost water by ÒsuckingÓ it up from the roots during the below freezing period. If on a tubing system, during this negative pressure period they tend to draw sap back into the tree from the dropline. Sap, once it enters the droplines, is quickly contaminated with microbes. When they are drawn back into the tree, tap hole closure is initiated. The problem is compounded in 3/16- inch tubing because, unlike 5/16-inch tubing, the smaller diameter collection tube remains full of sap. A Cornell study found that up to 12 feet of sap in a 3/16-inch tube can be drawn back into the tree during this recharge time. CV spouts are one proven method of limiting this drawback with 5/16 inch tubing. The question was: will they also be effective with 3/16-inch tubing that is full of sap?
Climate Change & Maple
Dr. Tim Perkins (Director-University of Vermont Proctor Maple Research Center) discusses the intimate relationship between weather and maple sap flow, changing climatic conditions have the potential to affect the maple industry in a variety of ways. This presentation describes research that has been conducted on climate change and maple as well as new ongoing work, and describe some possible effects of changing climate on the future of the industry in the northeast.
Asian Longhorned Beetle
This presentation by Tim Barwise (MA-DCR) the 2018 Vermont Maple Conferences covers the current infestation and the USDA-APHIS response to asian longhorned beetle (Anoplophora glabripennis) in the greater Worcester, MA area.
