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, informa
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 ...
On the other hand, the main advantage of using NMR spectroscopy is the high capacity in structure elucidation of compounds, which is the main lack of MS based methods. These two advanced analytical techniques would better ideally joined, thus ensuring the deepest characterization approach. The ...
This chapter deals with the principles and the applications in food science of 2D T1-T2and D-T2correlation techniques in time domain NMR (TD-NMR) spectroscopy. These approaches have demonstrated their potential for the structural and dynamic characterization of foodstuffs. Because relaxation or diffusi...
In this work, we utilized 1H NMR spectroscopy to identify specific metabolomic trends associated with the maturity of Navel oranges in cold storage. In particular, the focus is to determine metabolites that correlate with the Brix or Acid measurements and investigate complementary 1H NMR-based ...
and structural information in the study of food and plant products. In the past decade, the rapid development of modern analytical technology has led to the emergence of new approaches and strategies for natural products discovery. Especially the application of novel NMR- and MS-based identification...

To identify food and beverages containing potential anti-amyloidogenic compounds, an experimental protocol based on NMR spectroscopy combined with other biophysical and biochemical assays, was developed to detect ligands of amyloid aggregates in natural edible matrices. This approach was effective in identi...
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 ...
Here we have investigated the serum metabolic responses to two breakfast meals: an egg and ham based breakfast and a cereal based breakfast using three different multivariate approaches based on the Projections to Latent Structures framework. Methods: In a cross over design, 24 healthy volunteers ...
