Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Liquid–Liquid Equilibrium Data for Refined Olive Pomace Oil + Oleic Acid + Ethanol + Water Systems: Application to Solvent Deacidification

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT This study presents the first experimental liquid–liquid equilibrium (LLE) data for quaternary systems composed of refined olive pomace oil, oleic acid, ethanol, and water at 303.15 K. These data are essential for the design and optimization of solvent‐based deacidification processes, particularly for oils with high free fatty acid (FFA ...

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,
