Optimization of Gallic Acid Production from Terminalia Chebula by Aspergillus niger
E-Journal of Chemistry, 2007 A method for producing gallic acid by microbiological hydrolysis of the tannins of myrobalan seed powder is described in the present work. Hydrolysis of gallotannins of the substrate to gallic acid by Aspergillus niger MTCC 282 was studied.

Spectrophotometric Determination of Gallotannins in Beer
Journal of AOAC INTERNATIONAL, 1973 Abstract A method for the determination of traces of gallotannins in beer, in the presence of other natural tannins, has been developed. The procedure is based on the formation of a deep blue iron-tannin complex which is evaluated spectrophotometrically at 530 nm.

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates
Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...
