Check-valve spouts vs. standard clear spouts
Leader Evaporator Co. Check-Valve (CV) spouts and adapters incorporate a small, free-floating ball which is designed to reduce or prevent backflow of sap into the taphole during freezing, when leaks in the tubing system occurs, and when mechanical releasers dump and introduce air into the system. Several studies over nearly a decade have compared sap yields from CV adapters and spouts to various non-CV spouts and adapters.
Chemical and microbial characterization of ropy maple sap and syrup
Ropiness of maple syrup is a phenomenon that can occur several times in the season. The alteration known as ÒropinessÓ is characterized by a viscous, thick, slimy/jelly-like texture which, although not noticeably altering the taste, renders the product unpleasant in terms of mouthfeel. The aim of this study was to estimate the economic impact of production of ropy maple syrup in the region of Quebec, to more deeply identify and characterize bacteria associated to this type of quality defect, and to study the composition of Polysaccharides found in stringy maple syrup.
Chemical composition and properties of maple sap treated with an ultra high membrane concentration process
Nanofiltration and Reverse Osmosis are membrane concentration processes originally used by maple syrup producers to preconcentrate the sap to a moderate °Brix level (8–16 °Brix). The purpose of this study is to evaluate the potential of new membrane technology to concentrate maple sap to ultra-high °Brix and to investigate the effect of this concentration on the chemical composition and physical properties of final sap concentrate. Maple sap was concentrated up to 42 °Brix using two industrial membrane units. The contents of main solutes increased with the °Brix of concentrates depending on the specific rejection rate of the membranes tested. A slight and significant decrease was observed in the availability of some solutes such as K+, Mn++ and polyphenols in ultra-high-concentrated sap. However, the apparent organoleptic and physical properties of these concentrates have not been altered. According to the results of this, the new membrane process allows to produce ultra-high °Brix concentrate of maple sap with interesting properties. However, further works have to be performed on this technology to more precisely determine the highest °Brix level that will minimise the affect on chemical composition and properties of concentrated sap and the corresponding maple syrup.
Chemical composition of five standard grades of pure maple syrup
The objective of this study was to characterize the chemical composition of the five maple syrup grades, including their pH, conductivity, mineral and carbohydrate contents. In general, quantification of the range of chemical composition for each standard maple syrup grade will strengthen the existing knowledge of maple syrup chemistry.
Chemical Composition of Scale in Maple Syrup Evaporators
The goal of this work was to investigate the chemical composition of the scale that is deposited on maple evaporator surfaces during sap processing. Knowing the chemical composition of scale produced in modern equipment and how it compares to previously published values for loose sugar sand may aid in understanding how best to remove these unwanted deposits.
Chemical Safety in Maple Sugaring Operations
This brochure is intended to raise awareness among sugarmakers about hazardous chemicals commonly being used in sugaring operations as well as the need to use these materials safely, in a way which protects personal and food product safety. This brochure will outline 1) the most common types of chemical hazards associated with sugarhouse chemicals, 2) basic guidelines for using chemicals safely, and 3) where to get more detailed information.
Choose wisely when selecting where to tap
Knowing when, where, and how to tap is critical to making good maple syrup and keeping trees healthy.
Cleaning Tubing Systems
There are a number of ways to clean tubing systems to avoid microbial contamination of tapholes and 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.
