Potential Plastic Residues in Maple Sap and Syrup Following Isopropyl Alcohol Sanitation of the Tubing System
In recent years isopropyl alcohol (IPA) sanitation was proposed after the sugar season to significantly reduce the microbial load and start the next sugar season with a sanitized system. This study was conducted to evaluate the potential leaching of chemical compounds found in plastic polymers used in maple sap collection system tubing.
