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.
