Includes bibliographical references (page 9). "The traditional production of maple syrup by boiling in open pans is being re-appraised in the light of fuel and energy conservation. The dilute sap collected at between 1° to 4° Brix is concentrated to 65° Brix by boiling for an average 30-40 fold concentration. With reverse osmosis (R.O.) systems, high permeate flow rates are easily attained at low soluble solids levels"--Introduction, page [1]. Maple syrup industry Canada. Sirop d'érable Industrie Canada.
