Selective Transfer Hydrogenation of Polyenes to Monoenes Catalysed by Shvo's Catalyst

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
We report the reduction of polyenes to monoenes with near‐perfect selectivities at full conversion with isopropanol as hydrogen source. The reaction is catalysed by Shvo's catalyst and the selectivity towards conjugation, semihydrogenation or full hydrogenation can be adjusted via the reaction temperature.

Carbohydrate–Protein Hydrogels as Fat Replacers: Design Criteria and Benchmarking Against Full‐Fat Systems

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Reducing saturated fat while preserving the sensory quality of full‐fat foods remains a major formulation challenge because fat contributes simultaneously to body, lubrication, flavor delivery, and thermal transitions. Carbohydrate–protein (CP) hydrogels are increasingly explored as oil‐free fat replacers, but many systems are developed and ...
