Rapid Determination of Food Quality Using Steady State Free Precession Sequences in TD-MNR Spectroscopy Check Access

The use of relaxometry and diffusometry methods has significantly expanded the application TD-NMR in food science over the last two decades. TD-NMR has therefore become one of the most rapid, cost-effective and versatile tools in the food industry. However there remains a growing demand for increasingly rapid and accurate food quality assessment methods. This chapter details the theoretical basis for the authors' work into developing steady-state free precession (SSFP) pulse sequences for TD-NMR spectroscopy as a potentially more time-efficient and robust TD-NMR analytical technique. These SSFP sequences possess several strengths in relation to other quantitative analysis techniques and so can be used as alternatives and complementary methods to existing Carr-Purcell-Meiboom-Gill (CPMG) pulse sequences when using Continuous Wave Free Precession (CWFP) or CP-CWFP regimes.
