Unstable proteins in wine and their removal by bentonite and gallotannins

open access: yes, 1996
A range of commercially available 'new generation' gallotannins were trialled as a bentonite substitute for protein stabilisation of white wines. Gallotannins can precipitate proteins from model protein solutions and unfined wines.

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

open access: yesComprehensive 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 ...
