      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

      Restructured dry cured ham with diff erent pig back fat levels were manufactured. An increase in back fat level from 2 to 4% enhanced the neutral lipase and LOX activities, and facilitated the release of unsaturated fatty acid and the generation of volatile compounds including esters, ketones, aliphatic and aromatic hydrocarbons during ripening.

      These two figures show contrasting results obtained from one set of samples using esterification with GC (left hand figure), and Nile Red staining with fluorescence measurement (right hand figure). The Nile Red method indicates a high accumulation of lipids over time in 0.3 M NaCl, whereas the GC method indicates the opposite pattern of decreasing FAME content over time in the high salt conditions (green line in each figure). The contrasting results highlight the problem of accuracy in lipid measurement, and how it is possible to be misled if only one experimental technique is used.

      The enzymatic process with 3 h of reaction time showed the advantage of selectivity for production of new TAG and lower acyl migration sn-2 position of the unsaturated fatty acid when compared with the other reaction times, evidenced by NMR 13C. These SL were projected to have broad applications in foods, as bakery/confectionery fats and as a crystallization additive for lipids.

      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.

      This 3-month randomized trial reported examines and compares the effects of 25 mL/day supplementation of crude hybrid palm oil (Elaeis oleifera × Elaeis guineensis), thought to be a possible tropical equivalent of the Mediterranean extra-virgin olive oil, to the ones of extra-virgin olive oil, which is considered as a gold standard in the functional dietary oils skyline. Interestingly, at the end of the third month of study, the effects obtained by the supplementation with hybrid palm oil are similar to those provided by the extra-virgin olive oil supplementation. In fact, hybrid palm oil consumption has been shown to significantly increase the total phenolic content (19.2%, p < 0.01) as well as the antioxidant capacity of human plasma measured by both TEAC (42.9%, p < 0.01) and ORAC (92.1% p < 0.01) assays.

      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.

      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

      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.

      Restructured dry cured hams (RDH) with different pig back fat levels were successfully manufactured. This work shown that large differences in the neutral lipase and LOX (Lipoxygenase) activities 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 neutral lipase and LOX activities during ripening.

      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.

      Version of Record online: 22 JUN 2016 | DOI: 10.1002/ejlt.201500322

      Thumbnail image of graphical abstract

      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.
