Assessing the Potential of Gabiroba Fruit Waste as an Oil Source via Ultrasound-Assisted Extraction: Physicochemical Parameters, Chemical Profile, and Biological Properties

This study aimed to evaluate the impact of ultrasound-assisted extraction (UAE) on the chemical composition and biological activities of gabiroba waste oil (GWO), compared to conventional Soxhlet extraction (SE). GWO was characterized for carotenoid content and analyzed by GC-MS...

Influence of Residual Lignin on Mechanical Fibrillation and Colloidal Stability of Cellulose Nanofibrils from Eucalyptus Kraft Pulp

Eucalyptus kraft pulping represents an important source for the production of lignin-containing cellulose nanofibrils (LCNF); however, the influence of controlled residual lignin levels on fibrillation energy demand and suspension stability remains poorly understood. This study e...
