Protease, Amylase and Lactase Enzyme Stability in Gastroval® Capsules after Incubation at Acidic pH and Elevated Temperature

Abstract

The stability of plant-derived enzymes present in digestion-alleviating food supplement capsules Gastroval® was studied by determining the survival of enzymatic activity of proteases, α-amylases, and lactases (β-galactosidase) after an exposure to acidic pH and elevated temperature. Most of the enzymatic activity after the prolonged (2 h) exposure to acidic conditions (pH 2.0) and elevated temperature (50°C) remained unchanged or slightly reduced, thus indicating that the enzymes would pass the stomach without losing their entire enzymatic activity and efficiently alleviate food digestion in the intestine.
