Pan‐Frying Conditions Affect the Tocopherol Intake From Edible Oils: Results From Temperature Measurements and the Standardized Heating of an Edible Oil

Journal of the American Oil Chemists' Society, EarlyView.
High temperatures in a short time on electric stoves in private homes. Fast loss of tocochromanols using standardized conditions and a miniature heating apparatus. ABSTRACT Tocochromanols (vitamin E compounds) are essential ingredients in human nutrition. Their consumption via edible oils is considered the main source of dietary intake.

Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

Journal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

Environmental and Genetic Effects on the Composition of Palm Oil From Hybrid Plant Clones of Caiaué and Oil Palm

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The interspecific hybrids (IEH OxG) obtained from the crossing of Elaeis oleifera (Eo) and Elaeis guineensis (Eg) are resistant to some diseases that affect Eg in some regions of South America, and commercial growing in several countries has been established.

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,

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

Journal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.

Mechanical Properties and Thermo‐Oxidative Aging of Hybrid EPDM Formulations With Bio‐Based Oils

Journal of Applied Polymer Science, EarlyView.
This study evaluates bio‐based oil as an eco‐friendly replacement for paraffinic oil in EPDM rubber. While pure bio‐oil matches conventional mechanical properties, specific blends (25% and 75%) improve tensile strength and stiffness. The 50% blend requires tempering to optimize its sulfur network and morphology, eventually yielding a 35% strength ...
