Characterization and classification of Romanian acacia honey based on its physicochemical parameters and chemometrics.

ABSTRACT: Three groups of Romanian acacia honey, i.e., pure, directly adulterated (by mixing the pure honey with three sugar syrups), and indirectly adulterated (by feeding the bees with the same syrups), were characterized and discriminated based on their physicochemical parameters. Moisture, ash, 5-hydroxymethylfurfural (HMF), reducing sugars (fructose and glucose), and sucrose contents, free acidity, diastase activity, ratio between stable carbon isotopes of honey and its proteins (δ¹³C_H and δ¹³C_P) were evaluated. Adulteration led to a significant increase in sucrose content, HMF level, and Δδ¹³C = δ¹³C_H‒δ¹³C_P as well a decrease in reducing sugar content and diastase activity. Principal component an
