Nature conceals an exceptional variety of molecules as various as they’re imperceptible. The plant kingdom is especially chemically advanced.
Plant evolution has taken place over tons of of thousands and thousands of years, giving crops the flexibility to answer varied environmental stresses and threats. A number of species have developed an arsenal of molecules permitting them to adapt and to guard themselves in opposition to opponents and predators. A few of these molecules even have well being advantages for the animals that devour them.
Advances in meals science over current a long time present that many crops present a wealth of advantages that, till just lately, had been largely unknown. Taken collectively, these discoveries assist greater than ever the truth that a various and balanced eating regimen presents advantages that transcend easy power consumption. In consequence, shopper demand for plant-based meals with greater dietary worth is at the moment at report highs. This pattern has but to expire of steam. On the identical time, sugary meals are more and more marginalized and categorized as unhealthy.
However within the realm of sweets, maple syrup is lastly claiming its rightful place! Maple syrup is now not solely the jewel of Canada’s culinary heritage, its dietary fame can be enhancing. Due to its distinctive pure supply and manufacturing course of, maple syrup comprises bioactive molecules whose advantages go far past the easy pleasure of a candy deal with.
Advantages that transcend power consumption
In jap Canada, March and April herald maple sugaring time. Greater temperatures trigger maple bushes to transform their power reserves (saved as advanced carbohydrates) into soluble sugars that blend with the water within the tree. Producers accumulate the flavoured sap by drilling holes within the bushes.

The sap is roughly 98 per cent water, and it takes about 40 litres of this maple water to generate one litre of syrup. Throughout this focus course of, the degrees of sugars and vitamins enhance considerably. The excessive temperature that comes from boiling the sap causes a sequence of chemical reactions as the surplus water evaporates.
The principle parts of maple syrup are sucrose and water. Glucose and fructose additionally contribute to the candy style of the syrup, however to a lesser extent. Whereas these three easy carbohydrates are sources of power, maple syrup can be a wonderful supply of manganese and riboflavin (vitamin B2), in addition to a major supply of different nutritional vitamins and minerals (zinc, potassium, calcium and magnesium).
The composition of phenolic compounds of maple syrup is much more spectacular. Because the starting of the twentieth century, researchers have found greater than 100 of those molecules in crops. Lots of them are antioxidants, and contribute to the style, aroma, color of maple syrup. They’re primarily liable for its current superfood standing.
One of the promising phenolic parts (when it comes to organic actions) is a molecule discovered nowhere apart from in Canada’s most well-known product.
A molecule worthy of nationwide satisfaction
Quebecol – named after the province the place the vast majority of the world’s maple syrup manufacturing originates – is a polyphenolic compound (carrying a number of phenol teams), first remoted in 2011 by a workforce led by Navindra Seeram on the College of Rhode Island. This compound is so unique to maple syrup that it isn’t even current in uncooked maple sap! Moderately, present information suggests that it’s the product of chemical reactions that happen in the course of the transformation of sap into syrup.
Construction of quebecol [2,2,3-tris(4-hydroxy-2-methoxyphenyl)propan-1-ol], a molecule completely present in maple syrup whose secrets and techniques are simply starting to be revealed.

Early laboratory research, quebecol inhibited cell proliferation of breast most cancers and colon most cancers cells. However solely a small amount of polyphenol could possibly be remoted, and these checks didn’t transcend the preliminary stage. Greater than 20 litres of maple syrup is required to isolate lower than a milligram of quebecol.
Judging that this syrup can be of higher use in kitchens than in laboratories, Normand Voyer, a chemistry professor at Laval College, and I (Sébastien) determined to sort out this provide drawback. After I was a PhD candidate in 2013, we printed a chemical synthesis pathway to construct this pure molecule way more effectively within the laboratory from easy precursors. As this work made quebecol way more accessible, the investigation of its properties continued and deepened.
Specifically, Normand Voyer, Daniel Grenier and their groups, within the school of dentistry of Laval College, printed two research demonstrating the molecule’s anti-inflammatory properties. This analysis additionally made it potential to find out the energetic portion of the molecular construction.
A compound nonetheless related right now
Our 2021 examine confirmed that quebecol’s anti-inflammatory properties might profit periodontal illness, a extreme an infection of the gums. We count on further research to be printed this 12 months, together with one displaying that quebecol may assist with the remedy of a pores and skin situation.
Though the proof of organic exercise of quebecol has been restricted to in vitro experiments, these outcomes definitely encourage additional examine in additional advanced programs. It’s also vital to notice that the outcomes got here from utilizing the remoted pure molecule.
These research don’t suggest utilizing pure maple syrup as a medicinal agent in opposition to totally different situations. Given the amount of maple syrup one must eat to get the required dose of quebecol, the harms from a large ingestion of sugar would obscure any profit. It’s additionally troublesome to determine the distribution of the molecule within the human physique when it’s taken orally.
In any case, these discoveries as soon as once more spotlight the distinctiveness of maple syrup and assist to strengthen its standing as a singular meals. Maybe it comprises different equally promising molecules simply ready to be found. Let’s wager that this native treasure has not but revealed all its secrets and techniques!
