Polysaccharides from pinhão seeds of Araucaria angustifolia: Extraction, isolation and structural characterization

Journal of Food Composition and Analysis, 2023
Araucaria angustifolia is one of the main conifer species with great economic importance. Its seeds, known as pinhão, play a fundamental role in ecosystem conservation and have promising potential for application in the food/nutraceutical industry. This study aimed to elucidate the fine chemical structure of polysaccharides, showing for the first time ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...
