Abstract This study aimed to develop a headspace solid-phase microextraction gas chromatography–mass spectrometry (HS–SPME–GC–MS) method for the quantification of 3-monochloropropane-1,2-diol fatty acid esters (3-MCPDEs) and 2-monochloropropane-1,3-diol fatty acid esters (2-MCPDEs), and semi-quantification of glycidyl fatty acid esters (GEs) in edible oils. A central composite design was implemented to optimize the derivatization temperature and extraction time, which were 100 °C and 80 min, res...

Abstract A novel blue pigment was first isolated from Streptomyces sp. A1013Y. The purified component was identified as 4,8,13-trihydroxy-6,11-dione-trihydrogranaticins A (TDTA). Its physical properties were found to be: Molecular weight 462Da; Color value, E0.1%1cm580 nm=80; Solubility, it dissolved in organic solvents. In addition, the color of TDTA changed with pH but was found to be relatively stable between 20 and 100°C, from pH 3 to pH 11, and under UV-light or darkness. TDTA’s functional ...

Abstract Mechanically separated chicken (MSC) was obtained by two different separation methods (MSC1, Beehive separator, 3–5 d-old bones; MSC2, Poss separator, fresh bones) and compared to chicken breast trim (CBT). Rheological attributes of myofibrillar protein solutions during thermal gelation and cooling were evaluated. All sources exhibited gelation with increased temperature (decreased δ). In all three treatments, a peak, decline, and subsequent increase in both the G' and G'' was observed ...

Abstract The reaction of Ne-(carboxymethyl) lysine (CML) with eight kinds of non-flavonoid o-benzoquinones and five kinds of flavonoid o-benzoquinones were investigated by cyclic voltammetry at pH 5.0, 7.0 and 8.0 and scan rate of 10, 50 and 100 mV/s. The reactivity of o-benzoquinones towards CML is weakened by the electron-donating substituent and strengthened by the electron-withdrawing substituent on the o-benzoquinone rings. The steric hindrance of the substituents on o-benzoquinone rings al...

Abstract Grape seed maturation involves the gradual oxidation of tannins, decreasing excessive bitterness and astringency in wine. In cool climates, this process is limited by the short growing season, affecting wine quality. A “freeze-thaw” treatment on seeds of red vinifera cultivars at veraison and harvest was used to evaluate the effect of oxidation and extractability on seed phenolic fractions. Freezing increased the extraction of total phenolics and o-diphenols quantified from fractionatio...

Abstract Cadmium-contaminated rice has been a serious food safety issue in China. In this research, carboxymethyl rice starch (CMS) from cadmium-contaminated rice and native rice was prepared to remove the cadmium in rice. The preparation of native rice starch (NRS) and starch from cadmium-contaminated rice (Cd-CRS) was similar, and carboxymethyl starch was prepared following the same steps. A single factor experiment was performed to obtain the carboxymethyl starch prepared under the optimal co...

Abstract Methylcellulose (MC) polymer was used to prepare the edible films. Then, the Rheum ribes L. ethanol extract (RE) was added to the films in order to act as a natural antimicrobial agent. All the methylcellulose films were characterized for bioactivity and the physicochemical analysis were carried out to define functional group interactions between the polymer and RE. The strongest antimicrobial effect was obtained with MC films enriched with 2% (w/w) RE against to Listeria monocytogenes ...
