Comparison of 3/16″ and 5/16″ tubing sanitation

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. 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.

Composition and Properties of Maple Sap, Concentrate, and Permeate

Reverse osmosis is used widely in the maple syrup industry to concentrate maple sap and increase the overall efficiency and profitability of syrup pro-duction. Sets of samples from maple producers utilizing a range of sap con-centration levels were collected and analyzed to provide a portrait of the phy-sicochemical properties and chemical composition of maple sap, concentrate, and permeate across a single production season. The results reinforce that re-verse osmosis functions essentially as a concentration process, without signifi-cantly altering the fundamental proportions of sap constituents.

Effect of the new high vacuum technology on the chemical composition of maple sap and syrup

Techniques used to produce maple syrup have considerably evolved over the last decades making them more efficient and economically profitable. However, these advances must respect composition and quality standards as well as authenticity of maple products. Recently, a new and improved high vacuum technology has been made available to producers to achieve higher sap yields. The aim of the present study was therefore to evaluate the effect of this new system on the yield of sap and on the sap and syrup chemical composition.
