Physicochemical Analysis and Digestive Enzymes Inhibition of a Selected Malaysian Apis cerana Honey.

The Malaysian Apis cerana honey (ACH) was analysed for its physicochemical characteristics, including moisture, Baume, Brix analysis (total soluble solids and total soluble sugars), sugar profiling (fructose, glucose, sucrose, maltose, and lactose), total ash, pH, free acidity, electrical conductivity, colour analysis, and choline content. The inhibitory effects of pancreatic lipase, α-amylase, and α-glucosidase activities were also assessed. Results indicated that the sum of fructose and glucose, sucrose, and electrical conductivity were all within the recommended range following the requirements of international standards. The maximum levels were, nevertheless, exceeded by moisture, free acidity and total ash. The ACH showed potential as an anti-obesity and anti-diabetic agent by inhibiting pancreatic lipase by up to 43.4% at 0.063 mg/mL, α-amylase by up to 70% at 7.0 mg/mL and α-glucosidase by up to 67.6% at 100 mg/mL, respectively. The percentage inhibition of α-glucosidase by undiluted ACH and deionised water extract at different temperatures (4.8 ± 0.5 °C, 27 ± 0.5 °C, and 40 ± 0.5 °C) was comparable, suggesting that temperatures had little effect on the degree of inhibition.
