H-1 Nuclear Magnetic Resonance Relaxometry and Magnetic Resonance Imaging and Applications in Food Science and Processing

2016-03-01
Low-field bench top H-1 nuclear magnetic resonance (LF-NMR) relaxometry instruments have been increasingly popular as analytical tools for engineering research. Magnetic resonance imaging, which is a more advanced approach to NMR technology, provides the researcher with images of the internal structure without any disruption to the sample and has been commonly used in medical applications in analysis of soft tissue. The non-invasive and non-destructive nature coupled with the high discriminative power of LF-NMR and MRI, makes them invaluable tools of analysis for a wide range of applications in food science. This review covers the basic concept behind NMR/MRI technology and discusses some of its most commonly used food applications. The review addresses the food scientist with no prior knowledge of NMR/MRI and aims to supply the reader with both the theory of the method and its fundamentals, as well as the practical uses in scientific research and industrial applications.

Real-time benchtop NMR spectroscopy for the online monitoring of sucrose hydrolysis
Soyler, Alper; Bouillaud, Dylan; Farjon, Jonathan; Giraudeau, Patrick; Öztop, Halil Mecit (Elsevier BV, 2020-01-01)
The online monitoring of chemical reactions by using benchtop Nuclear Magnetic Resonance (NMR) spectroscopy has become increasingly attractive for the past few years. The use of quantitative online NMR spectroscopy is a promising alternative to traditional analytical methods with its rapid, quantitative and non-invasive nature that makes it applicable to complex and diverse biochemical mixtures like food systems. In this study, sucrose hydrolysis by invertase was chosen as a model reaction for online monito...
Experimental and mathematical investigation of mass transfer in food andhydrogel systems using magnetic resonance imaging and NMR relaxometry
Çıkrıkcı, Sevil; Öztop, Halil Mecit; Department of Food Engineering (2019)
Nuclear magnetic resonance (NMR) and Magnetic Resonance Imaging (MRI) are well-known non-invasive characterization methods used in a wide range of areas; from medical to food applications. NMR experiments are conducted either through spectroscopy with high resolution systems or with relaxometery (Time Domain NMR) through mid or low field systems. Time domain NMR is primarily based on relaxation times and diffusion measurements from the signal coming from the whole sample while MRI enables to visualize the i...
TiN(IV) oxide coated gold nanoparticles: synthesis, characterization and investigation of surface enhanced raman scattering activities
Elçi, Aylin; Nalbant Esentürk, Emren; Department of Chemistry (2017)
Noble metal nanoparticles (i.e. gold (Au) and silver (Ag)) have received enormous attention due to their superior optical properties related to localized surface plasmon resonance (LSPR) and their potential applications in sensing, imaging, catalysis and optoelectronic devices. In particular, the ones with anisotropic morphologies have attracted intense interest from the researchers because of their superior optoelectronic properties. High electromagnetic field forms on the nanoparticle surface. The intensi...
System integration of MEMS devices on flexible substrate for fully implantable cochlear implant applications
Soydan, Alper Kaan; Külah, Haluk; Department of Micro and Nanotechnology (2019)
This master thesis is a result of multidisciplinary research bringing together concepts in electronics engineering, implant technologies, materials science, microfabrication, and device physics. Advancements in healthcare technology and in-vivo implants, electronic devices implemented on flexible substrates are highly demanded in the near future. In order to create a physically flexible device which consists of rigid sub-systems serving distinct purposes and made up of varying types of materials, we need re...
Identification of spindle dynamics by receptance coupling for non-contact excitation system
Özşahin, Orkun; Budak, Erhan; Rabréau, Clément; Le Loch, Sébastien (Elsevier BV; 2019-01-01)
The identification of spindle dynamics plays a crucial role in accurate prediction of the stability diagrams for high speed machining operations. In this study, variations of the mode shapes of the tool-spindle assembly at high spindle speeds are examined using numerical models and hypotheses are formulated. An identification method of spindle dynamics is proposed, dedicated to non-contact excitation system; from which only cross FRF can be obtained (instead of tool tip FRF classically). Then, spindle dynam...
