In a overview article printed within the journal Heliyon, scientists have supplied an in depth overview of the dietary, pharmacological, and sensory properties of maple syrup.

Background

Maple syrup is a pure sweetener that’s extensively used as a substitute choice to keep away from using refined sugar. Maple syrup has a considerably decrease glycemic index than refined sugar and, thus, can be utilized to scale back the danger of diabetes, weight problems, and different metabolic illnesses.

Maple sap collected from sugar maple bushes is boiled and concentrated to supply maple syrup. It comprises various bioactive phenolic compounds, natural acids, amino acids, minerals and nutritional vitamins, phytohormones, and macronutrients (primarily carbohydrates). These compounds collectively improve maple syrup’s dietary, pharmacological, and sensory properties.

Dietary properties of maple syrup

Maple syrup is a wealthy supply of carbohydrates and, thus, gives a substantial portion of the typical vitality wants of the human physique. Minerals (potassium, calcium, zinc, sodium, iron, and magnesium) and nutritional vitamins (niacin, thiamine, and riboflavin) current in maple syrup are important for varied organic processes, such because the synthesis of enzymes and hormones and upkeep of bone, muscle, coronary heart, and mind features.

Many animal research have proven that maple syrup has hepatoprotective results, together with suppression of ammonia formation, regulation of lipogenesis and lipolysis, and discount of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ranges. Furthermore, average maple syrup consumption has been discovered to manage blood glucose ranges in sort 2 diabetic rats. A purposeful oligosaccharide maplebiose1 recognized in maple syrup has been discovered to play a big function in controlling blood sugar ranges in diabetes.

Polyphenol-enriched maple syrup extracts have been discovered to stop high-fat diet-induced metabolic adjustments in mine. Mechanistically, these extracts have been discovered to cut back blood ranges of low-density lipoprotein (LDL)-cholesterol by rising ketone physique manufacturing from acetyl-CoA.

Various comparative research have proven that maple syrup has comparable dietary properties as different pure sweeteners (brown rice syrup, blue agave syrup, corn syrup, and pure honey). Nevertheless, scientific trials in people are wanted to correctly perceive the dietary and well being advantages of maple syrup in comparison with different pure sweeteners. 

Pharmacological properties of maple syrup

Glycosylated phenolics and aglycones are two teams of antioxidant compounds present in maple syrup. Ethyl acetate–soluble fractions of maple syrup have been discovered to have robust antioxidant properties.

Relating to antioxidative properties, research have proven that maple syrup extracts inhibit lipopolysaccharide (LPS)-induced overproduction of nitric oxide, suppress H2O2-induced manufacturing of reactive oxygen species (ROS), and subsequently forestall oxidative DNA and protein harm.

Apart from antioxidant properties, phenolic compounds current in maple syrup possess potent anti-inflammatory properties. Research have proven that maple syrup-derived phenolic compounds can forestall irritation by decreasing the manufacturing of nitric oxide, nitrite, and prostaglandin-E2. Furthermore, maple syrup extracts have been discovered to cut back the manufacturing of LPS-induced inflammatory biomarkers, together with nitric oxide species, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha).

Maple syrup-derived polyphenolic compound quebecol has been discovered to strongly suppress LPS-induced Nuclear Issue Kappa B (NF-κB) activation, resulting in a discount of irritation.

The anticancer results of maple syrup extracts have been studied in varied most cancers varieties, together with prostate, lung, breast, and colorectal cancers. On this context, proof signifies that maple syrup-derived phenolic compounds can considerably inhibit the proliferation of most cancers cells by arresting the cell cycle, decreasing AKT phosphorylation, or inhibiting expressions of tumor suppressor genes. Research have additionally discovered that phenolic compounds of darkish maple syrup have greater anti-proliferative efficacy than these of amber maple syrup.

In animal fashions of sort 2 diabetes, phenolic-based maple syrup extracts have been discovered to inhibit porcine α-amylase and α-glucosidase enzymes, that are answerable for the digestion of carbohydrates and starches to glucose for intestinal absorption.

Many bioactive compounds current in maple syrup have neuroprotective exercise and, thus, can forestall the pathogenesis of age-related neurodegenerative illnesses, together with amyotrophic lateral sclerosis (ALS). Maple syrup compounds have been discovered to exert anti-aging actions by decreasing the formation of superior glycation finish merchandise (AGEs).

Relating to Alzheimer’s illness, proof signifies that maple syrup extracts forestall the aggregation of β-amyloid (Aβ) and tau peptides, that are two pathological hallmarks of Alzheimer’s illness.  

Glycosylated and aglycone phenolic compounds derived from maple syrup extracts are identified to have antimutagenic exercise. Totally different phenolic compounds of maple syrup, comparable to gallic acid, catechol, catechaldehyde, syringaldehyde, vanillin, and 3-hydroxybenzoic acid, are identified to have antimicrobial actions in opposition to Gram-negative micro organism.

Sensory properties of maple syrup

Natural acids, free amino acids, protein, and phenolic compounds of maple syrup are answerable for its sensory properties. Research investigating sensory properties of maple syrup have proven that 5′‐inosine monophosphate is answerable for the style of maple syrup; enolic viscous oil is answerable for syrup odor; vanillin, syringaldehyde, dihydroconiferyl alcohol, acetol, acetoin, ethyl vanillate, syringoyl methyl ketone, and methyl cyclopentenolone are answerable for syrup taste.   

These chemical compounds are answerable for the general sensory traits of maple syrup and provides maple syrup a novel character to differentiate it from different pure syrups.
