      Extra-virgin olive oil is a turbid colloidal dispersion. The most common technique used to clear the oil is filtration. During this process, quantitative and qualitative changes take place, especially on minor components.

      The most frequently used formulation form for health supplements is tablets, however, to date there have been numerous issues with achieving sufficient oil load and maintain oxidative stability trying to formulate omega-3 oil in tablets. Totox 26 is the limit set by the Global Organization for EPA and DHA (GOED) for omega-3 supplement for human use (yellow line). As presented in this figure, omega-3 tablets with 30% w/w triglyceride oil load (60% concentrate) have been prepared and totox have maintained lower than 26 for tablets kept at 37°C for 1 year. The data so far obtained from the long-term stability study (tablet samples kept at ambient conditions) indicate the possibility for a +3 years shelf life for the omega-3 tablets.

    1. The obesity-related Adipokinetic hormone controls feeding and expression of neuropeptide regulators of Drosophila metabolism

      Martina Gáliková, Peter Klepsatel, Yanjun Xu and Ronald P. Kühnlein

      Version of Record online: 21 JUN 2016 | DOI: 10.1002/ejlt.201600138

      Adipokinetic hormone (AKH) is an insect analog of the human hormone glucagon. Our investigations of the roles of this hormone in the model organism Drosophila melanogaster have shown that this anti-obesity factor is a central regulator of fly metabolism, and controls crucial processes such as feeding, metabolic rate, storage of energy reserves, and expression of regulatory genes from the neuropeptide hormone family, including the fly homologs of human insulin.

    2. The influence of crusher speed on extra virgin olive oil characteristics

      Lorenzo Guerrini, Marzia Migliorini, Matteo Giusti and Alessandro Parenti

      Version of Record online: 21 JUN 2016 | DOI: 10.1002/ejlt.201600156

      Crushing speed can be used to characterize olive oils. Faster crushing significantly increases chlorophyll, total biophenol, 3,4-DHPEA-EDA, and p-DHPEA-EDA. Panel testing found higher bitterness and astringency scores in oils produced at the higher speed.

    1. High quality, good health: The case for olive oil

      Elena Bernardini and Francesco Visioli

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/ejlt.201500505

      The use of high-quality extra-virgin olive oil activates a virtuous cycle by which consumers become more aware of their health and of the influence of proper diet on it. This translates into a better overall diet and, in turn, better prognosis.

    1. Application and comparison of high-speed countercurrent chromatography and high-performance liquid chromatography in semi-preparative separation of decarboxymethyl oleuropein aglycone (3,4-DHPEA-EDA), a bioactive secoiridoid from extra-virgin olive oil

      Cecilia Jiménez-Sánchez, Jesús Lozano-Sánchez, Margret Brüggemann, Mariana Neves-Vieira, Miriam Rodriguez-Werner, Eva Schmalfuß, Peter Winterhalter, Antonio Segura-Carretero and Alberto Fernández-Gutiérrez

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/ejlt.201500532

      Thumbnail image of graphical abstract

      This paper compares high-speed countercurrent chromatography (HSCCC) and high-performance liquid chromatography (HPLC) in semi-preparative isolation of decarboxymethyl oleuropein aglycone (3,4-DHPEA-EDA), a bioactive secoiridoid, from extra-virgin olive oil (EVOO). An EVOO phenolic extract (EVOO-PE) was obtained by solid-phase extraction (SPE), and this extract was subjected to one run using the maximum loading capacity of each methodology without loss of resolution. For this sample set, the HSCCC method proved to be a more efficient approach regarding loading capacity, solvent consumption, and throughput compared with the HPLC method. However, the purity of the target from HPLC was superior to that of HSCCC, as the number of theoretical plates could not match that of HPLC.

    2. Comparisons between a self-microemulsifying system and lipid nanoparticles of oxyresveratrol on the physicochemical properties and Caco-2 cell permeability

      Yaowaporn Sangsen, Kamonthip Wiwattanawongsa, Kittisak Likhitwitayawuid, Boonchoo Sritularak and Ruedeekorn Wiwattanapatapee

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/ejlt.201600053

      Thumbnail image of graphical abstract

      The lipid nanoparticles (SLN and NLC) and self-microemulsifying drug delivery systems (SMEDDS) of oxyresveratrol (OXYR) were produced using different compositions and methods. The appearance and characteristics of the lipid-based systems were different. However, all of three lipid-based formulations significantly improved intestinal permeability and reduced efflux transport of OXYR. Therefore, these systems could be used as a potential carrier for oral delivery of OXYR or other compounds which are substrates for efflux transporters.

    1. Quality changes of Antarctic krill powder during long term storage

      Nina Skall Nielsen, Henna Fung Sieng Lu, Inge Bruheim and Charlotte Jacobsen

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/ejlt.201600085

      Antarctic krill (Euphausia superba) is a shrimp-like marine crustacean. It is rich in omega-3 fatty acids, primarily bound in phospholipids in the sn-2 position of the molecule, making it highly bioavailable. Krill may be processed into powder also rich in protein and astaxanthin. Stability of krill powder, stored for up to 12 months at room temperature, showed slight lipid oxidation.

    1. Improving phospholipase activity of PLA1 by protein engineering and its effects on oil degumming

      Qun An, Fanghua Wang, Dongming Lan, Faez Iqbal Khan, Rabia Durrani, Bo Yang and Yonghua Wang

      Version of Record online: 15 JUN 2016 | DOI: 10.1002/ejlt.201600110

      Thumbnail image of graphical abstract

      The phospholipase activity of PLA1 can be improved by protein engineering based on bioinformatics analysis. With its properties of hydrolyzing sn-1 position ester bond of phospholipids, nonhydratable phospholipids were converted into their hydratable forms, PLA1 can be applied in oil degumming. PLA1 with higher phospholipase activity is more likely to suitable for oil degumming since it could decrease the phosphorous content of oil lower than 10 mg/kg within shorter reaction, which showed great potencial for degumming application.

      Version of Record online: 8 JUN 2016 | DOI: 10.1002/ejlt.201500573

      Thumbnail image of graphical abstract

      Nine raw fish oils are stored under different conditions and analyzed by 1H NMR spectroscopy as well as by traditional methods to determine the lipid quality parameters peroxide value, anisidine value, TOTOX value, and acid value. Subsequently, PLS regression models are generated to predict these indices from the NMR spectra.

    4. Incorporation of pig back fat in restructured dry cured ham to facilitate the release of unsaturated fatty acids and generation of volatile compounds

      Teng Hui, Yawei Zhang, Muneer Ahmed Jamali and Zengqi Peng

      Version of Record online: 8 JUN 2016 | DOI: 10.1002/ejlt.201600025

      Thumbnail image of graphical abstract

      Restructured dry cured hams (RDH) with different pig back fat levels were successfully manufactured. This work shown that large differences in the free unsaturated fatty acid and volatile compounds of RDH can be caused by the exogenous pig back fat incorporation. An increase in pig back fat level from 2 to 4% in RDH significantly enhanced the release of unsaturated fatty acid, and facilitated the generation of volatile compounds including esters, ketones, aliphatic hydrocarbons, and aromatic hydrocarbons.
