I was wondering about the use of formaldehyde in maple syrup production. I've heard various differnet stories, including that some differnet grades of maple syrup contain it and some diddn't. I found out that's not true. The grade just means when it's harvested. Grade A is early season, B is middle and C is later. The later in the season the darker the syrup, and all are ok for the cleanse although I gather B is preferred.
I contacted the manufacturer of the bottle of syrup that I happened to buy and got this response:
Thank you for your e-mail as well as for your interest in our Maple Syrup!
We certainly do not make use of formaldehyde and you may consume our Organic Maple Syrup at ease. Formaldehyde pellets were used by maple syrup producers in the late 1980's and early 1990's in order to prevent the tap holes to heal and consequently boosting their production. This practice has been illegal since and the Inspectors from the Canadian Health Food Inspection Agency visit different sugar bushes during spring in order to ensure that this illegal substance remains unused. Shady Maple Farm has also set in place a quality program with very strict measures for the control of our organic raw ingredient.
Hoping the above is beneficial to you and should you require additional information please do not hesitate to contact us.
Have a great day!
