    1. Influence of atmospheric pressure argon plasma treatment on the quality of peanut oil

      Cuirong Ren, Guoqing Huang, Shiqing Wang, Junxia Xiao, Xubo Xiong, Hufeng Wang and Yanling Liu

      Version of Record online: 28 AUG 2017 | DOI: 10.1002/ejlt.201600513

      Thumbnail image of graphical abstract

      A total of 5 mL peanut oil is transferred to a weighing bottle (diameter 40 mm) and exposed to atmospheric pressure argon plasma at a flow rate of 0.5 L/h for 100 s. The voltage of the power supply is set to 150, 155, 160, 165, or 170 V to explore the effects of plasma density on peanut oil quality. Treatment by the plasma generated in voltages 0∼170 V shows no effect on the acid value, but significantly reduces the iodine value, increases the peroxide value, and brightness of peanut oil in a voltage-dependent manner. Exposure to the plasma generated in 170 V significantly reduces the contents of oleic acid and linoleic acid by 2.14 and 2.99%, respectively, but exhibits no effect on that of palmitic acid.

      Overview of polyunsaturated fatty acids (PUFA) potential effects on bacteria adhesion. (1) Unabsorbed PUFA directly effects bacteria in the colon. (2) Systemic delivery of PUFA following absorption can (a) Bind peroxisome proliferator-activated receptors (PPAR), that can lead to production of transforming growth factor-β resulting in tolerance towards bacteria. (b) Be precursors for series 3 prostaglandins (PG) that lead to lower inflammatory responses. (c) Be precursors to series 2 PG and enhance inflammatory products, however, precursors can bind PPAR and result in inhibition of inflammatory responses. (d) Unsaturated PUFAs lead to a more fluidic membrane composition, potentially altering bacterial adhesion sites.

    2. Lipids from visceral depot fat of Asian seabass (Lates calcarifer): Compositions and storage stability as affected by extraction methods

      Version of Record online: 2 AUG 2017 | DOI: 10.1002/ejlt.201700198

      Thumbnail image of graphical abstract

      Lipids from Asian seabass visceral depot fat are extracted using different methods including heating in air, heating under vacuum, autoclave, and solvent extraction. Extraction by heating under vacuum rendered the lipid with the highest yield and the oxidation occurred at the low extent. During storage of 30 days at 30°C, lipids extracted by heating under vacuum also have the high oxidative stability. Therefore, Asian seabass viscera could be the potential raw material of lipid rich in n-3 fatty acids, which can be extracted and used as nutraceutical or supplement.

    1. Partial coalescence in double (W1/O/W2) emulsions prepared with skimmed milk, polyglycerol polyricinoleate, and different fats

      María P. Pérez, Jorge R. Wagner and Andrés L. Márquez

      Version of Record online: 5 JUL 2017 | DOI: 10.1002/ejlt.201600447

      Thumbnail image of graphical abstract

      The stability against partial coalescence in W1/O/W2 emulsions containing polyglycerol polyricinoleate (PGPR) and solid fat in lipid phase is linked to the retention of inner water droplets or the encapsulation efficiency of the system. The higher the inner osmolality the higher the encapsulation efficiency; and the higher the encapsulation efficiency the lower the partial coalescence degree. This aggregation of fat globules is attributed to the increase of collision frequency due to protein displacement by PGPR at the outer interface and/or the increase of capture efficiency due to the modification of fat crystals by PGPR.

    2. Novel type of carbon-centered antioxidants arylmethyl Meldrum's acids − inhibit free radicals

      Thumbnail image of graphical abstract

      Monosubstituted Meldrum's acids act as carbon radical scavengers due to the presence of acidic hydrogen in the moiety of cyclic 1,3-dicarbonyl compound. The substituted Meldrum's acids demonstrate high scavenging capacity of free radicals DPPH and GO. These compounds turned out as powerful antioxidants for inhibition of oxidation processes of fatty acid alkyl esters. The antioxidant activity of the substituted Meldrum's acids in fatty acid esters is both due to benzylic position and 1,3-dicarbonyl moiety. Few of the monosubstituted Meldrum's acids were better antioxidants than BHT, TBHQ, α-tocopherol, or vitamin C.

      Version of Record online: 3 JUL 2017 | DOI: 10.1002/ejlt.201700154

      Thumbnail image of graphical abstract

      High behenic acid stabilizers (HBS) are used to stabilize fat-structured and oil-rich food products. It is shown that HBS interacts with high-melting triacylglycerols (HMTs) present in the fats and oils to be stabilized and reduces their free energy of nucleation, as shown in the graphical abstract. This leads to the formation of large numbers of smaller, stabilizing crystals in the system. Moreover, it also shown that HBS interacts differently with different HMTs. It displays incompatibility with tristearin and tripalmitin but displays compatibility with the high melting fraction of milkfat. A greater molecular compatibility is postulated to lead to greater stabilization.

      Epicatechin (E) and quercetin (Q) microparticles designed with inulin (IN, encapsulating agent) and soy protein isolate (SPI, channelizing agent) are incorporated to sunflower oil (SO). The channels formation is observed for Q–In–SPI and E–In–SPI by confocal laser scanning microscopy. The induction period (IP) of SO (Rancimat at 60°C) significantly increases when Q-microparticles with or without SPI are added, showing those with SPI the highest IP value. Regarding E systems, the IP of SO increases only when E–In microparticles with SPI are added. No clear effect of SPI incorporation is observed in additional oxidation studies under conditions of lower oxygen availability.
