Effects of Extrusion Conditions and Oil Addition on the Characteristics of Cheese‐Flavored Corn Snacks and Food Bolus Formation and Properties

Journal of Texture Studies, Volume 57, Issue 4, August 2026.
The independent variables influenced the oral processing of corn snacks, and temporality had a low importance in characterizing them. The sunflower oil content had little impact on their sensory profile, suggesting that low sunflower oil content may be sensorially acceptable, contributing to improved nutritional value of corn snacks.

Deep Eutectic Solvent‐Type Mixture as a Green Catalyst in the Solvent‐Free Cycloaddition of CO2 and Epoxides

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
A green, metal‐free catalytic system based on a deep eutectic solvent‐type mixture of tetrabutylammonium iodide and levulinic acid enables the solvent‐free cycloaddition of carbon dioxide (CO2) to epoxides. Cooperative acid–nucleophile activation affords cyclic carbonates in up to 95% yield at atmospheric pressure using only 1.4 mol% of catalyst.
