Independence of Thermal, Pasting, and Gelling Properties From Particle Size in Cereal Flours Across Heating Temperatures

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study investigated how particle size influenced pasting and gelling behaviors of cereal flours across a wide range of heating temperatures. Hard wheat, soft wheat, oats, barley, and rye were milled into flours using 0.5‐, 1.0‐, or 2.0‐mm screens, and the resulting flours were subjected to heating over 95°C–140°C ...

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.
