Maple syrup is made by collecting and concentrating maple sap by
boiling. Maple syrup making was common to all the tribes in Colonial
America and Canada and quickly adapted by European settlers. The dominant sugar of maple syrup is sucrose
with small amounts of glucose and fructose as well as trace concentrations
of polysaccharides and oligosaccharides). The pH of maple syrup varies
from 4.73 to 8.26; the central value reported is pH 6.7. Syrup pH varies primarily due to soil mineral content
and the bacterial and
yeast populations in the lines collecting the syrup.
