Safflower oil serves as a key component in the formulation of oil-in-water (O/W) emulsions, with its phase fraction playing a critical role in determining emulsion stability. This study explores the impact of safflower oil fractions (0.4-0.7) and magnetic field-modified soy 11S globulin (MF-11S) concentrations (1%-5%) on emulsion properties.
To prepare the emulsions, soy 11S globulin was dispersed in distilled water (5% w/v), subjected to a 5 mT magnetic field for 90 minutes at 4 °C, and subsequently diluted to different concentrations. After 12 hours of hydration, safflower oil (0.4-0.7 v/v) was homogenized with MF-11S solutions at 12,000 rpm for 2 minutes.
Results indicated that emulsions with lower (0.4-0.5) or higher (≥0.7) safflower oil fractions exhibited phase separation, whereas intermediate fractions (0.6-0.65) combined with 3%-5% MF-11S formed stable, solid-like emulsion gels. Increasing the safflower oil fraction significantly improved viscosity, gel strength, and storage stability (P < 0.05), while higher MF-11S concentrations reduced droplet size and enhanced structural integrity (P < 0.05).
The combination of safflower oil at 0.65 fraction and 5% MF-11S provided optimal emulsion stability, highlighting safflower oil's potential for structured emulsions in food and pharmaceutical applications requiring controlled texture and extended shelf life.

Safflower oil, rich in linoleic acid, serves as an ideal precursor for the synthesis of conjugated linoleic acid (CLA) through heterogeneous hydrogenation and isomerization. This study explores the transformation of safflower oil using mesostructured catalysts under controlled hydrogenation conditions.
The reaction was conducted in a 600 mL Parr Pressure Reactor, where 200 g of safflower oil was combined with a catalyst (0.005 g metal/100 g oil). To eliminate oxygen interference, the reactor was purged with nitrogen prior to hydrogen introduction. The temperature was gradually increased and maintained at either 180°C or 210°C, while hydrogen pressure was regulated at 4 or 7 psi. The reaction was continuously stirred at 300 rpm, and oil samples were periodically analyzed for fatty acid composition and iodine value over 300 minutes.
Results demonstrated that varying temperature and hydrogen pressure significantly influenced CLA formation. Higher temperatures (210°C) and increased hydrogen pressure (7 psi) favored the isomerization of linoleic acid to CLA while maintaining controlled saturation levels. These findings highlight safflower oil's potential as a sustainable feedstock for CLA production, offering applications in functional foods and nutraceuticals.
The study underscores the role of mesostructured catalysts in optimizing CLA yield, paving the way for efficient industrial-scale production of bioactive lipids from safflower oil.

Safflower oil has emerged as a promising renewable feedstock for the production of sustainable jet fuel through catalytic hydrodeoxygenation (HDO). This study evaluates the performance of cobalt-based catalysts supported by various metal oxides (γ-Al₂O₃, TiO₂, ZnO, and ZrO₂) in converting safflower oil into hydrocarbon-based biofuels.
The reaction was conducted in a pressurized reactor containing 100 mL of safflower oil and 1% catalyst, without a solvent. The system was purged with nitrogen before hydrogen was introduced at pressures of 25, 50, or 75 bar. The catalytic efficiency of Co/γ-Al₂O₃ was first optimized by varying reaction time (4-8 h) and temperature (300-400°C). Once optimal conditions were established, the catalytic performance of Co catalysts with different supports was systematically compared.
Upon reaction completion, products were separated via centrifugation, weighed, and analyzed by gas chromatography-mass spectrometry (GC-MS). Results showed that Co/γ-Al₂O₃ exhibited superior catalytic activity and selectivity, efficiently converting safflower oil into hydrocarbon fractions suitable for aviation fuel applications. Alternative supports, such as TiO₂ and ZrO₂, also demonstrated potential but with varying selectivity profiles.
These findings highlight safflower oil's viability as a renewable alternative for jet fuel synthesis, offering a sustainable solution to reduce reliance on petroleum-based hydrocarbons.
