Nowadays, NMR analysis is often based on the behavior (relaxation) of NMR active nuclei (i.e. 1H, 13C which are the most widely used for food applications) in a magnetic field and a pulsed Radio Frequency (RF) irradiation. Relaxation describes a complex process of the nuclei from ...
Low-field 1H NMR relaxometry is an important tool used to investigate on the most abundant components of intact foodstuffs based on relaxation parameters and amplitude of the NMR signals. In particular, information on water compartments, diffusion and movement can be obtained by detecting proton signa...
In recent years, researchers have developed multiple in vitro digestion models and approaches to study gastric digestion (Gouseti, Bornhorst, Bakalis, & Mackie, 2019). These models are useful for studying the molecular mechanisms behind protein breakdown, and have the advantage of well-controlled ...

High-resolution magic-angle spinning (HRMAS) is a fairly recently developed technique in NMR spectroscopy, whose main feature is to allow the significant reduction of anisotropy in semisolid materials and obtain high-resolution NMR spectra, when a rotor
Multiple response analysis based on suitable desirability functions yielded a combination of factors resulting in desirability values above 0.8 for 1H LF-NMR signals and almost 1.0 for 13C LF-NMR signals. In addition, a novel approach to assess the information quality of an analytical signal was ...
In this work, low-field proton (1H) and sodium (23Na) relaxation and diffusion measurements are used to detect and classify different types of food products. A compact and low-cost system based on a small 0.5 T permanent magnet has been developed to autonomously authenticate such products...
Dammarane-type saponins (DTSs) exist in various medicinal plants, which are a class of active ingredients with effects on improving myocardial ischemia and immunomodulation. In this study, a quantitative 1H NMR method of total DTSs in herbal medicines was developed based on the analytical procedure...
Oil palm (Elaeis guineensis Jacq.) leaflets (OPLs) are one of the major agricultural by-products generated from the massive cultivation of Malaysian palm oil. This biomass is also reported to be of potential value based on its health-improving effects. By employing proton nuclear magnetic resonanc...
