Lycopene‐rich food biomolecules from tomato processing waste: Green recovery, biopolymer‐based stabilisation, functional food applications and health relevance

open access: yesFood Biomacromolecules, EarlyView.
Abstract Tomato processing waste, particularly peel and pomace, is a sustainable and low‐cost source of lycopene‐rich food biomolecules. Lycopene, a lipophilic carotenoid with an extended conjugated structure, provides intense red colour, antioxidant potential and functional value to tomato‐derived ingredients.

Optimization of Ultrasound‐Assisted Extraction of Seabuckthorn (Hippophae salicifolia) Seed Oil With the Use of Response Surface Methodology

open access: yesFuture Postharvest and Food, EarlyView.
Ultrasound‐assisted extraction (UAE) of seabuckthorn seed oil enhanced yield (17.95%), antioxidant activity (IC50: 5.25 μg/mL), and carotenoid content (266.63 mg/100 g). The oil, rich in unsaturated fatty acids (83.15%), exhibited superior quality, thermal stability, and potential applications in food, cosmetics, and pharmaceuticals, making UAE a ...

Supercritical Fluid Chromatography

open access: yesInternational Journal of Advanced Research in Science, Communication and Technology, 2023
History of Supercritical Fluid Chromatography In 1822, the French physicist Charles Cannard de La Tour placed a liquid and a flint ball in a Papin rifle pressure vessel and heated the liquid with a sealed cannon. 1) When the container was shaken, the bullet broke through the air-liquid interface, and the sound of the bullet scattering was heard.

Anti‐Inflammatory Effects of Punicic Acid and Its Molecular Mechanisms in RAW264.7 Cells and Zebrafish

open access: yesFood Safety and Health, EarlyView.
Punicic acid (PA) was enriched and purified from PSO by molecular distillation with significant anti‐inflammatory activity to RAW264.7 cells, as well as to zebrafish. Anti‐inflammatory mechanism involved regulating NF‐κB and MAPK signaling pathways. ABSTRACT Punicic acid (PA) is the main fatty acid in pomegranate seeds, which shows multiple biological ...
