Spectrophotometric assay of immobilized tannase
Journal of Biosciences, 1981 A procedure for the assay of immobilized tannase with Polyacrylamide gel, collagen and Duolite-S-762 as matrices is described. It is based on the spectrophotometric determination of gallic acid formed by the enzymatic hydrolysis of tannic acid. The kinetic parameters of the enzymatic reaction have been studied and an assay procedure has been formulated.

Visual Reading Method for Detection of Bacterial Tannase [PDF]
Applied and Environmental Microbiology, 1993 Tannase activity of bacteria capable of degrading tannin-protein complexes was determined by a newly developed visual reading method. The method is based on two phenomena: (i) the ability of tannase to hydrolyze methyl gallate to release free gallic acid and (ii) the green to brown coloration of gallic acid after prolonged exposure to oxygen in an ...

Effect of Enzyme Treatment on Physicochemical and Phytochemical Properties of Guava Puree
Food Science &Nutrition, Volume 13, Issue 11, November 2025.Treating guava puree with 600 ppm Bioguavase for 3 h at 30 C effectively improves clarity while minimizing nutrient degradation. These conditions are suitable for producing a clarified juice by centrifugation after enzyme treatment of the puree. This protocol is recommended for industrial‐scale guava juice processing to enhance product quality and ...
