Sugar Concentration In The Tree Sap Of Five Species Of Minnesota Trees, Mark Ellman, Michael Ellman Apr 2018

Sugar Concentration In The Tree Sap Of Five Species Of Minnesota Trees, Mark Ellman, Michael Ellman

Celebrating Scholarship and Creativity Day (2018-)

Tree sap can be collected from a variety of species in Minnesota, including sugar maple (Acer saccharum), box elder (Acer negundo), red maple (Acer rubrum), paper birch (Betula papyrifera), and ironwood (Ostrya virginiana). The sap of different species contain varying concentrations of sugar, important for determining the amount of sap needed to boil down into a volume of syrup. In general, previous literature has shown that sugar maples have the highest concentration of sugar, followed by red maple, birch, and box elder. The sugar concentration of ironwood is as of yet unknown. The purpose of this study was to confirm …


Calcium Concentration In Tree Sap Of Five Species Of Minnesota Trees As An Indicator Of Sugar Sand, Michael Ellman, Mark Ellman Apr 2018

Calcium Concentration In Tree Sap Of Five Species Of Minnesota Trees As An Indicator Of Sugar Sand, Michael Ellman, Mark Ellman

Celebrating Scholarship and Creativity Day (2018-)

Tree sap can be collected from a variety of species (sugar maple, birch, ironwood, box elder, red maple) in Minnesota. When the sap of sugar maple trees and others are cooked into syrup, a cloudy mixture of minerals precipitates out. This precipitate, called sugar sand, gives syrup an unpleasant taste and can clog up machinery if improperly managed. Sugar sand primarily consists primarily of calcium malate. Thus, calcium concentration can be a good indicator of how much sugar sand would precipitate out if sap is processed into syrup. In general, previous literature has shown that sugar maple sap has the …
