As it passes through the evaporator, the boiling sap can begin to foam quickly, especially at a later stage of the production season. When excessive foaming occurs, the use of a foam control agent, commonly called "antifoaming agent" or "defoamer" in the maple syrup industry, sometimes becomes necessary to avoid problematic overflows (low productivity, loss of product, cleaning challenges, safety, etc.).For more information, we invite you to read the article “A Promising Alternative to Defoamers for Maple Production” written by Nathalie Martin, Fadi Ali, Jessica Houde, Stéphane Corriveau of the Centre ACER and published in the December 2024 issue of Maple Syrup Digest (Vol. 63, No. 4).
