Purification of α,β‐Unsaturated Carboxylic Acids as Their Potassium Carboxylate Salts Using Dry Column Vacuum Chromatography

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
Isolation of α,β‐unsaturated carboxylic acids from mixtures containing phosphine oxides (formed in Wittig‐type reactions) using standard procedures resulted in unsatisfactory outcomes in terms of product yield and/or purity. A new method involving purification of the products as their carboxylate salts using dry column vacuum chromatography enabled the

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 ...

Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho tailings dam disaster

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 634-646, May 2026.
Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...
