- Low field nuclear magnetic resonance (LF-NMR) relaxometry in hake (Merluccius merluccius, L.) muscle after different freezing and storage conditions.
- Sánchez-Alonso I1, Moreno P2, Careche M2.Author information 1Instituto de Estructura de la Materia (IEM-CSIC), C/Serrano n-121, E-28006 Madrid, Spain; Instituto de Ciencia y Tecnología de los Alimentos y Nutrición (ICTAN-CSIC), C/José Antonio Novais n-10, E-28040 Madrid, Spain. Electronic address: isabel.sanchez@csic.es.2Instituto de Ciencia y Tecnología de los Alimentos y Nutrición (ICTAN-CSIC), C/José Antonio Novais n-10, E-28040 Madrid, Spain.AbstractLow field NMR T2 transverse relaxation measurements were performed on muscle samples from sixty hake (Merluccius merluccius, L.). Fish fillets from hake stored in ice for 3 and 14days were subjected to different freezing methods (air blast, liquid nitrogen or walk-in freezer) and storage conditions (-20 and -10°C for 5days, 8 and 18weeks). Distribution analysis of T2 data of unfrozen muscle displayed a major band (T21), accounting for 90-92% of the total signal, with a relaxation time centred at 47-60ms and a broad band with protons of higher mobility between 300 and 800ms, accounting for 3-5% of the signal. Upon freezing, T21 became wider and an extra band appeared within the range 120-360ms. Whereas no changes were detected at -20°C, the T21 time constant decreased during frozen storage at -10°C in a similar way for all three freezing methods. The relative abundance of T21 declined with storage time but differences were found as a function of freezing. Results are discussed in the light of morphological alterations and protein denaturation, and it is concluded that LF NMR relaxometry is sensitive to different freezing and frozen storage conditions which can have important implications for the quality of fish muscle.

- Novel application of NMR relaxometry in studies of diffusion in virgin rape oil.
- Rachocki A1, Tritt-Goc J2.Author information 1Institute of Molecular Physics, Polish Academy of Sciences, M. Smoluchowskiego 17, 60-179 Poznań, Poland. Electronic address: radam@ifmpan.poznan.pl.2Institute of Molecular Physics, Polish Academy of Sciences, M. Smoluchowskiego 17, 60-179 Poznań, Poland.AbstractField cycling (FC) proton nuclear magnetic resonance ((1)H NMR) relaxometry was applied to study the dynamics of rape oil molecules. The spin-lattice relaxation data, measured in the frequency range from 0.01 to 30 MHz, were analysed by applying relaxation theory combined with the force-free-hard-sphere (FFHS) diffusion model. In the low frequency range, the relaxation was dominated by the translational diffusion contribution. Therefore, the diffusion coefficient of rape oil was determined from a linear dependence of the (1)H NMR relaxation dispersion drawn as a function of the square root of Larmor frequency. The results are consistent with those obtained from the pulse gradient spin echo (PGSE) NMR method. To estimate the density of oil protons, a parameter required to derive the diffusion coefficient from NMR relaxometry, a single point imaging (SPI) NMR experiment was proposed.

The objectives of this work were to compare free radicals properties and concentrations in different commercially available coffees, in solid and liquid states, and to determine the effect of roasting on the formation of free radicals in coffee beans of various origins. The free radicals content of 15 commercially available coffees (solid and liquid) was compared and the impact of processing examined using electron paramagnetic resonance (EPR) spectroscopy at X-band (9.3 GHz). First derivative EPR spectra were measured at microwave power in the range of 0.7-70 mW. The following parameters were calculated for EPR spectra: amplitude (A), integral intensity (I), and line-width (ΔBpp); g-Factor was obtained from resonance condition. Our study showed that free radicals exist in green coffee beans (10(16) spin/g), roasted coffee beans (10(18) spin/g), and in commercially available coffee (10(17)-10(18) spin/g). Free radical concentrations were higher in solid ground coffee than in instant or lyophilised coffee. Continuous microwave saturation indicated homogeneous broadening of EPR lines from solid and liquid commercial coffee samples as well as green and roasted coffee beans. Slow spin-lattice relaxation processes were found to be present in all coffee samples tested, solid and liquid commercial coffees as well as green and roasted coffee beans. Higher free radicals concentrations were obtained for both the green and roasted at 240 °C coffee beans from Peru compared with those originating from Ethiopia, Brazil, India, or Colombia. Moreover, more free radicals occurred in Arabica coffee beans roasted at 240 °C than Robusta. EPR spectroscopy is a useful method of examining free radicals in different types of coffee.
