      The study of the evolution of the composition of three sunflower oils submitted to heating at frying temperature over a prolonged period of time and of the composition of three sunflower oils derived frying media, formed throughout 14 deep-frying experiments of 3 different foods was carried out by means of 1H NMR.

    4. Adding talc particles improves physical properties of palm oil-based shortening (pages 1007–1017)

      Shinichi Yoshikawa, Haruyasu Kida, Yasuki Matsumura and Kiyotaka Sato

      Storage modulus (G′) of refined palm oil (RPO) with and without talc particles in bulk fat systems, obtained from dynamic viscoelasticity measurements during cooling at a rate of 5°C/min. Adding talc particles drastically changed the three-stage increases in G′ of pure RPO, promoting the first-stage increase but suppressing subsequent increases at low temperatures.

    5. Application of oxygen during olive fruit crushing impacts on the characteristics and sensory profile of the virgin olive oil (pages 1018–1029)

      The increase of oxygen concentration during crushing produces a significant change in the volatile composition and sensory profile; however, no significant differences were shown on the content of fatty acid composition, total phenols, pigments, tocopherols, and qualitative parameters. Oxygen availability can modulate the final composition of virgin olive oil.

      Rapeseed oils cold pressed from seeds subjected to roasting (140–180°C for 5–15 min) were compared to rapeseed oil that was cold pressed from seeds not exposed to elevated temperatures through an analysis of their oxidative stability, antioxidant activity, and levels of bioactive substances (tocopherols, plastochromanol-8, and canolol). The oils were stored for a period of 12 months at a temperature reflecting cold storage conditions (4°C). It was shown that the oils produced from seeds roasted at 180°C in particular exhibited greater oxidative stability and the best antioxidant properties. Antioxidant activity was shown to correlate with the levels of canolol (r = 0.9927; p < 0.0001) and g-T (r = 0.9765; p < 0.0001), as well as with total tocopherols (r = 0.9796; p < 0.0001).

    7. Oxidative stability, thermal decomposition, and oxidation onset prediction of carrot, flax, hemp, and canola seed oils in relation to oil composition and positional distribution of fatty acids (pages 1042–1052)

      Triglyceride structure and fatty acid contents of seed oils are analyzed by HPLC, positional location and fatty acid type. These are shown to affect onset of oxidation and thermal stability profiles. Instrumental methods of thermal analysis allow for rapid analysis of shelf-life prediction.

    8. Thermal oxidative stability analysis of hoki and tuna oils by Differential Scanning Calorimetry and Thermogravimetry (pages 1053–1061)

      Measurement of oxidative stability of fish oils by DSC and TGA follow the Q10 law on the relationship between temperature and rate of chemical reaction. Prediction of shelf life of the fish oils is possible by an Arrhenius extrapolation from elevated isothermal DSC and TGA analyses. Differences in the thermal behavior of the fish oils were consistent with major fatty acid compositional differences.

    9. Viscosity–temperature relationship of lipid-based excipients amenable for spray congealing: Derivation of a rheological parameter with good correlation to particle size (pages 1062–1073)

      A method for the determination of ergosterol, brassicasterol, and cholesterol has been developed by UPLC-UV. We found that a high-ergosterol diet induces the elevation of serum brassicasterol in SHRSP rats.

    11. Lifelong diet including common unsaturated fatty acids extends the lifespan and affects oxidation in Caenorhabditis elegans consistently with hormesis model (pages 1084–1092)

      Version of Record online: 15 OCT 2015 | DOI: 10.1002/ejlt.201500237

      Supplementation with 0.5 mg OA, 0.1 mg LnA or 0.5 mg ALA extended the lifespan of C. elegans by 10.49%, 14.17% or 8.47%, respectively (p < 0.05). At these doses, LnA and ALA significantly inhibited growth, pharyngeal pumping, reproduction and respiration, while OA did not influence these physiological activities and significantly increased superoxide dismutase, catalase and glutathione peroxidase activities. Using the eat-2, and sod-2 mutated strains, the anti-aging mechanism of OA was hormesis, while LnA and ALA acted via caloric restriction.

    12. Development and characterization of solid lipid microparticles containing vitamin C for topical and cosmetic use (pages 1093–1103)

      Solid lipid microparticles (SLMs), combined with the advantages of double emulsions (W/O/W) and water-in-oil micro emulsions, are developed for transdermal administration. A modified one-step emulsification method was introduced, which made the industrial production of SLMs easier. With vitamin C as a model active, the advantages of SLMs in transdermal administration were studied further. Vitamin C, encapsulated by SLMs, showed an enhanced storage stability up to 1 month and a sustained releasing profile over 24 h. Furthermore, the SLMs can facilitate skin's absorption of VC with pig as the model animal. These studies demonstrate that SLMs can be a promising method for facilitating transdermal penetration of active ingredients with high solubility and low permeability.

    13. Utilization of proteins from AluProt-CGNA (a novel protein-rich lupin variety) in the development of oil-in-water multilayer emulsion systems (pages 1104–1112)
