One of the major objectives of rice (Oryza sativa L.) breeding programs is the development of new varieties with higher tolerance/resistance to both abiotic and biotic stresses. In this study, Italian rice cultivars were subjected to osmotic stress or benzothiadiazole (BTH) treatments. An analysis of the expression of selected genes known to be involved in(More)
This work presents the capability of NMR spectroscopy combined with Chemometrics in predicting the ageing of Balsamic and Traditional Balsamic Vinegar of Modena. The need of an analytical method is an important requirement for both research oriented and commercial evaluation of these very valuable products. (1)H NMR spectroscopy, based on the advantage of(More)
In this paper, 22 samples consisting of Balsamic vinegar of Modena and two Traditional Balsamic vinegar of Modena samples have been analyzed by means of (1)H NMR spectroscopy. Some selected resonances have been used for quantification and for T1 (spin-lattice relaxation time) measurements. Statistical protocols applied to NMR data for quantification of(More)
In the present work, a preliminary study for the detection of adulterated saffron and the identification of the adulterant used by means of (1)H NMR and chemometrics is reported. Authentic Greek saffron and four typical plant-derived materials utilised as bulking agents in saffron, i.e., Crocus sativus stamens, safflower, turmeric, and gardenia were(More)
In this globalization era, the opening of the markets has put at almost everybody's disposal a wide variety of foods, allowing everybody to taste food flavors and aromas from different nations. Notwithstanding this opportunity, countries try to preserve their markets by developing protection policies. A few countries have adopted different denominations to(More)
Samples of Italian Parmigiano Reggiano cheese of different ripening stages (14, 24 and 30 months) were analyzed by (1)H NMR spectroscopy and the water-soluble metabolites content compared with samples of "Grana type" cheese from east Europe countries. Different multivariate statistical protocols were examined to build up a stable model for both ripening and(More)
This study reports direct quantification of arabica in roasted and ground coffee blends of Coffea arabica and Coffea canephora var. robusta. (1)H-NMR analysis of water extracts of coffee blends were combined with multivariate statistical analysis to obtain an OPLS model with high predictive capability. This approach allowed to evaluate the composition of(More)
The increasing attention for food quality and safety led to develop several analytical techniques suitable to address these demands. Coffee has been already demonstrated to represent a worldwide appreciated beverage and its high economical value could induce frauds or adulteration practices involving both compositional and geographical aspects. In the last(More)
Nuclear magnetic resonance (NMR) is nowadays largely used as valid tool in metabolomic applications. In this study, the metabolite content of Italian and Chinese tomato paste at different concentration rates of two production years (2007 and 2008) was investigated with the aim of building a robust geographical differentiation statistical model. A total of(More)
In previous works on authentic samples of saffron of known history (harvest and processing year, storage conditions, and length of time) some biomarkers were proposed using both FT-IR and NMR metabolomics regarding the shelf life of the product. This work addresses the difficulties to trace back the "age" of commercial saffron samples of unknown history,(More)
