Relating Spectrophotometer Readings to Visual Grading of Maple Syrup

Color grading of maple syrup is based on placing syrup samples within four or more categories based either on visual comparison to color references or measurement of light transmission with a spectrophotometer. With a spectrophotometer, specific transmission values are used as break points to divide syrup samples into color grades. The purpose of this report is to describe the lack of agreement between existing light transmission break points and visual grading and how this problem can be addressed.

Reverse Osmosis for Maple Syrup Option 2

Cornell University’s Maple Specialist, Steve Childs reviews a second reverse osmosis system for a small-scale maple syrup producer. Reverse osmosis greatly reduces the time and energy spent in boiling maple syrup by pulling much of the water from the sap before the boiling process begins. Sap can be put through the system repeatedly and becomes more concentrated with each pass through the RO membrane. Boiling the concentrated sap at the end is always necessary however, as that greatly contributes to maple syrup’s rich flavor.
