Density
The regulations on the production of maple states that the maple
syrup must have a minimum of soluble solid non fats of 66% at 20º C.
To verify this percentage, the classifier uses a well-calibrated refractometer
on which the scale is between 44 and 77 degrees centigrade (Brix). The refractometer is
also equipped with a temperature corrector.
Conductivity
With the help of the conductivity meter, the inspector who watches
over the application of the current regulations can rapidly recognize if the product is authentic.
Or else, he will request a more extensive analysis. Contrary to sucrose, maple products contain
a certain quantity of mineral elements that assure the passage of electric current between two
electrodes. They define the fields covered by the syrups at being 90 for lighter syrups
and 220 for darker syrups.
Maple syrup flavours
The consumer's reactions seem to confirm that the flavor is the most import criterion in
the classification of the maple syrup. This is the reason why the legislator provided categories to
distinguish them very well, the different flavors perceived by smell or by taste.
To inhale a sample of maple syrup before tasting it is a way of better appreciating it.
Seeing it is difficult to identify the exact flavor, the gustatory results are presented
in a grading report.
