----------------------------------------------------------------- Overview of NMR Applications to Food Biopolymers.
I.C. Baianu, University of Illinois at Urbana, Illinois 61801
A comprehensive survey of NMR techniques and their selective applications for the characterization of food biopolymers and related model systems will be presented. Both high-resolution and relaxation aspects of NMR applications to foods will be discussed, emphasizing the practical and potential uses of NMR in the food industry. Specific applications for a variety of foods and model systems will be illustrated at an intuitive and accessible level to the food processing engineer and R&D specialists. Other results recently obtained at the Agricultural & Food Chemistry NMR Facility in the ACES College at UIUC can be previewed on the Internet at the following URL addresses: http://www.ag.uiuc.edu/~fs401/AFC-NMR-FACILITY.html

NMR Relaxation studies of Surimi Analogs: Starch and Muscle Protein Hydration Determination.
P. Bechtel, Colorado State University, FSHN Dept, Fort Collins, CO, and P.H. Yakubu, University of Illinois at Urbana, AFC-NMR Facility, ACES College, Urbana, IL Recent NMR relaxation results for surimi analogs made of heart or gizzard muscle proteins with potato starches from selected cultivars will be presented and discussed in relation to developing novel food formulations. Determination of both hydration and structural changes in these food systems as a result of various thermal processing methods will be presented, and shown to be relevant to quality control and functionality in foods. ---------------------------------------------------------------------------------------------------------------------------------

Organic chelates of paramagnetic metal ions can be designed to exhibit various degrees of lipophilicity. The chemistry of these materials is of special interest to researchers who are designing paramagnetic MRI contrast agents with tissue-specific properties that can be exploited in both nutritional and medical diagnostic investigations. We are reporting the use of field-cycling NMR relaxometry , as well as multi-frequency EMR techniques to characterize the environment, dynamics, and water interactions of the chelates. In this paper, we will present results from novel 2-dimensional NMRD studies of Gd(III) chelates interacting with albumins and primary rat hepatocytes, as well as complementary EMR studies at frequencies from 1 to 250 GHz that relate to the presence of unpaired electrons in these systems. Changes in the rotational motion of the complexes, as well as in their effective "g-values" occur when such molecules interact with lipids. Partitioning effects are sometimes observable in the 2-dimensional NMRD profiles when water and paramagnetic chelate exchange rates are favorable. The new frequencies available for EMR studies have many potential applications in the characterization of membrane properties utilizing paramagnetic spin probes. Our novel methodology could therefore be applied, for example, to determine both eukariotic and prokariotic cell membrane fluidity. This work was supported in part by grants from the NIH (GM42208, GM51630, to RBC; RR01811 to RLB), and by Schering AG , and Nycomed AB.

Thursday , August 8, 1996, 1:30 PM to 3:30 PM ---------------------------------------------------------------- Magnetic Resonance Microscopy: Basic Principles and Applications D. Morris, Biomedical Magnetic Resonance Laboratory, University of Illinois at Urbana, 1307 W. Park. St., Urbana, IL. 61801 An overview of recent advances in Magnetic Resonance Microscopy will be presented with special emphasis of potential applications of these novel techniques to the characterization of foods and biological systems, in general. Specific illustrations will be shown to bring several important applications into focus. -------------------------------------------------------------------- Super-resolution, MR Imaging with A Priori Constraints Z.-P. Liang, Department of Electrical and Computer Engineering and Beckman Institute for Advanced Science and Technology, Urbana, IL. 61801 A classical problem with tomographic imaging is the so-called limited data reconstruction problem which occurs when physical and temporal constraints prevent sufficient coverage of the data space. Traditionally, image reconstruction is performed using the Fourier series model, which often results in spurious ringing, loss of spatial resolution, and motion artifacts. To overcome these problems, numerous methods have emerged in the past decade to incorporate a priori information into the imaging process. This paper is devoted to a discussion of the constrained imaging concept. Specifically, three model-based imaging methods will be discussed to illustrate how a priori constraints can be used to achieve super-resolution image reconstruction, to improve imaging efficiency with time-sequential imaging, and to suppress motion artifacts and improve temporal resolution with dynamic imaging. -------------------------------------------------------------------- Recent Developments and Applications of NMR Micro-coils. J.Stocker and R. Magin, Beckman Research Institute for Advanced Studies, University of Illinois at Urbana, Illinois A fundamental limitation in NMR micro-spectroscopy is the low signal-to-noise ratio (SNR). Microcoils, with diameters on the order of 500 micrometers or less, have been shown to provide enhanced sensitivity for RF detection from mass-limited and volume-limited samples. With solenoid microcoils, a SNR (per acquisition) higher than 100:1, and linewidths less than 1 Hz have been obtained. Such microcoils are employed for capillary electrophoresis --NMR, and liquid chromatography-- NMR. At dimensions of less than 100 micrometers, microlithographic fabrication techniques are now being employed to make planar microcoils (spiral inductors). With such planar microcoils, experimental results were obtained with SNR values of 25:1, and linewidths less than 2 Hz. These results demonstrate the application of these microcoils to high resolution microspectroscopy, and represent a critical component in the development of microcoil arrays, integrated pre-amplifiers, and eventually integrated NMR detectors.
