Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

open access: yesCarbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Phenolic‐Associated Dietary Fiber Ingredients From Agro‐Industrial Residues: Processing‐Dependent Identity and Food‐Grade Translation

open access: yesChemFoodChem, EarlyView.
Agro‐industrial residues contain dietary fiber and phenolics, but coexistence alone does not establish a phenolic‐bound ingredient. Processing‐dependent identity is verified through fraction‐specific analysis and common‐basis mass balance. Food‐grade translation requires final‐product performance, sensory acceptance, safety, and claim‐matched ...

Sequential Pressurized Liquid Extraction of Food Matrices: Fractionation, Selectivity, and Scale‐Up

open access: yesChemFoodChem, EarlyView.
Sequential pressurized liquid extraction separates food‐processing side streams into chemically distinct fractions by changing solvent polarity and operating conditions across stages. Lipophilic and phenolic compounds are recovered selectively, while co‐extraction is reduced.
