The flavor formation of fried food experienced an optimum stage, obtained more desirable during this stage. In order to improve the French Fries (FFs), stage was prolonged by adding several antioxidants (tert-butyl hydroquinone (TBHQ), L-ascorbyl palmitat (L-ap), and rosemary) frying soybean oil (SO). results sensory evaluation showed that had effect on prolonging Compared with control group, SO added TBHQ, L-ap rosemary 25%, 50% respectively. Furthermore, can effectively inhibit degradation...

A series of triarylphosphanes ( 1a , 2a 3a 4a 5a 6a 7a 8a 9a 10a 11a ) have been synthesized. An X‐ray crystal structure analysis (2‐bromophenyl)diphenylphosphane unambiguously confirmed the constitution functionalized phosphane. The hydrosilylation reaction styrene with triethoxysilane catalyzed RhCl 3 /triarylphosphane was studied. In comparison classic Wilkinson's catalyst, rhodium complexes triarylphosphane ligands are characterized by a very high catalytic effectiveness for alkene....

Flavor is a key element affecting the popularity of French fries (FFs). When oil heated, changes in quality can affect flavor food directly.The FFs showed three crucial stages: break-in (3.0% to 6.8% total polar compounds (TPC)), optimum (7.0% 19% TPC), and degrading (above 19.5% TPC) stages. To distinguish aroma stages, FFs, prepared palm (PO) at TPC 3.0% (FF3), 7.5% (FF8), (FF20), their relevant oils (PO3, PO8, PO20), were selected for molecular sensory science analysis. The results...

Heteroleptic copper compounds have been designed and synthesized on solid supports. Chemical redox agents were used to change the oxidation state of SiO2-immobilized heteroleptic from Cu(I) Cu(II) then back Cu(I). Optical spectroscopy a dimethyl sulfoxide suspension demonstrated reversibility Cu(I)/Cu(II) by monitoring metal-to-ligand charge transfer peak at about 450 nm. Electron paramagnetic resonance was monitor isomerization tetrahedral square planar. This conformational corresponds 90°...

Nonmesogenic cyclic alkylidene terephthalate is directly connected to flexible polyethylene main chain at every second carbon atom via the phenyl ring obtain a novel vinyl polymer, poly(alkylidene vinylterephthalate) (PAVT-n), where n (= 10−14 and 16) denotes number of methylene groups in side chain. When molecular weight large enough, stable hexagonal columnar phases are generated from melt by PAVT-n polymers with = 10−13, but not those containing 14 or 16 groups. Compared its open-ring...

Nonmesogenic cyclic oligoethylene oxide terephthalate is directly connected to flexible polyethylene main chain at every second carbon atom via the phenyl ring obtain a novel vinyl polymer, poly(cyclic vinylterephthalate) (PEOT-n), where n (= 4–6) denotes number of ethylene groups in side chain. Although no traditional mesogenic unit present repeating unit, one polymers, PEOT-4, displays columnar nematic phase. Those containing 5 or 6 are not liquid crystalline. Compared with its carbonic...

Fourier transform infrared (FTIR) spectroscopy combined with backpropagation artificial neural network (BP-ANN) were utilized for rapid and simultaneous assessment of the lipid oxidation indices in French fries. The conventional indexes (i.e. total polar compounds, oxidized triacylglycerol polymerized products, monomers, hydrolysis acid value), FTIR absorbance intensity fries determined during deep-frying process, results showed had better quality palm oil, followed by sunflower rapeseed oil...

A series of silylated triarylphosphines was synthesized. Hydrosilylation reactions styrene with triethoxysilane catalyzed by RhCl 3 /silylated triarylphosphine complexes were investigated. The /phenylbis(4‐trimethylsilylphenyl)phosphine and /tris(4‐trimethylsilylphenyl)phosphine exhibited higher activity as well greater β‐adduct selectivity, no unsaturated product obtained. results suggest that the silyl moieties have a significant impact on catalytic process.

As a key species in the Antarctic food web, krill (Euphausia superba) is potentially healthy source of lipids, containing two most important omega 3 fatty acids. However, degree unsaturation long-chain polyunsaturated acids, especially those from family, makes dry samples vulnerable to oxidative degradation during long-term storage. The ontogenetic and temporal variation acids tissues preserved under ambient temperature unclear. To investigate effects storage at temperatures on krill, acid...

Abstract A single‐source precursor route is presented to prepare small‐sized Ni particles (∼5 nm) uniformly embedded into SiO 2 sheet (Ni/SiO ). The synthetic process involved the coordination of APTES (3‐aminopropyltriethoxysilane) with 2+ form Ni−Si in high yield, followed by pyrolysis under NH 3 atmosphere. During heating, Si component was transformed , which could restrict in‐situ generated from aggregation, resulting formation particles. Small size conducive promoting catalytic...

Poster Sessions is to reveal the crystallinity of those metal complex layers which has not been studied yet.We made structural analysis on a ultra-thin film grown substrate using synchrotron x-ray reflectivity and grazing angle diffraction (GAXD).An iron oxalate layer copper rubeanate an ultra-smooth sapphire (0001) by wet method were measured.The ultrasmooth was used make interface as smooth possible [2].The wavelength incident x-rays 0.1nm.The measurements performed at BL13XU, SPring-8.The...
