Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste

Advanced Sustainable Systems, Volume 9, Issue 9, September 2025.
Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.

Highly Targeted Metabolomics Coupled With Gene Expression Analysis by RT–qPCR Improves Beef Separation Based on Grass, Grain, or Grape Supplemented Diet

Food Frontiers, Volume 6, Issue 3, Page 1483-1497, May 2025.
ABSTRACT The objective of this study was to use a multi‐omics (i.e., gene expression quantification, metabolomics, and fatty acid [FA] profiling) approach to separate and authenticate beef from three different dietary groups. In this 2‐year study, Red Angus steers (n = 54) were randomly allocated to one of three treatments: (1) complex biodiverse ...
