A 2D NMR method to characterize granular structure of dairy products

Detection and quantification of milk adulteration using time domain nuclear magnetic resonance (TD-NMR)

“…The results showed that the T 2 relaxation was characterized by one 1 H component. This result agrees with previously studies found in the literature, which reported that the proton transverse relaxation in skin milk is mainly mono-exponential due to the fast diffusive exchange of water between the different compartments [21][22][23]. Table 1 describes the T 2 found by mono-exponential fitting.…”

Experimental techniques for characterising water in wood covering the range from dry to fully water-saturated

“…Even more details about the chemical environment of water in pores within wood can be gained from T 1 to T 2 2D LFNMR correlation spectroscopy as reported by Cox et al (2010). In this method, T 1 and T 2 relaxations are determined simultaneously allowing an analysis of their correlation (Song 2009;Song et al 2002). This is useful since T 2 relaxation occurs both as a result of realignment of M, like T 1 relaxation, and due to local interactions independent of T 1 relaxation.…”

Influence of the incorporation of fibers in biscuit dough on proton mobility characterized by time domain NMR

“…NMR relaxometry has made an important advance with the advent of a fast algorithm for two dimensional inverse Laplace inversion, being the signal recorded as a function of two time variables, T 1 and T 2 , where T 1 is the spin-lattice relaxation time (Song, 2009;Song et al, 2002). The advantage of this procedure is that T 1 and T 2 are measured simultaneously and the two dimensional (2D) spectra, showing peaks characterized by their intrinsic T 1 and T 2 values contain more information than conventional one dimensional relaxation time spectra.…”
