Flow injection determination of total catechins and procyanidins in white and red wines [PDF]
, 2002 An easily automatable flow-injection (FI) method for the determination of total catechins is reported. The method is based on the reaction of vanillin in acid medium to yield a coloured product with maximum absorption at 500 nm. After optimisation by the

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions
Advanced Functional Materials, EarlyView.Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

Colour, health and wellbeing: the hidden qualities and properties of natural dyes [PDF]
, 2013 This paper addresses the questions: Is it feasible that the chemicals present in the natural dyes of both plants and insects which in the past, man has exploited for their colour, could exhibit other properties?

Comparing Hydrolysable and Condensed Tannins for Tannin Protein-Based Foams
PolymersTannin-based foams have gained attention as a potential bio-based alternative to conventional synthetic foams. Traditionally, namely condensed tannins (CT) have been used, leaving the potential of hydrolysable tannins (HT) largely unexplored.
