“…Another recent study should be noted, which reports the use of PSYCHE NMR with statistical analysis to detect adulteration of honey and to assess the geographical origin of tea. 64 However, the results were less convincing compared to conventional 1D NMR, probably because the pulse sequence did not include the SAPPHIRE module, which further justifies the potential impact of this recent methodological advance. While 1D pure-shift NMR experiments are sensitivity-limited, this is not the case of heteronuclear 1 H- 13 C 2D experiments where pure-shift spectra can be obtained in the 1 H dimension at no cost in terms of sensitivity, and with a substantial gain in resolution.…”

NMR-Based Metabolic Profiling of Edible Olives—Determination of Quality Parameters

et al. 2020

Edible olive drupes (from Olea europaea L.) are a high-value food commodity with an increasing production trend over the past two decades. In an attempt to prevent fraud issues and ensure quality, the International Olive Council (IOC) issued guidelines for their sensory evaluation. However, certain varieties, geographical origins and processing parameters are omitted. The aim of the present study was the development of a method for the quality assessment of edible olives from the Konservolia, Kalamon and Chalkidikis cultivars from different areas of Greece processed with the Spanish or Greek method. A rapid NMR-based untargeted metabolic profiling method was developed along with multivariate analysis (MVA) and applied for the first time in edible olives’ analysis complemented by the aid of statistical total correlation spectroscopy (STOCSY). Specific biomarkers, related to the classification of olives based on different treatments, cultivars and geographical origin, were identified. STOCSY proved to be a valuable aid towards the assignment of biomarkers, a bottleneck in untargeted metabolomic approaches.

“…The nuclear magnetic resonance (NMR) spectroscopy applied to fruit profiling may represent a reliable alternative in terms of a non-invasive and powerful method that combines targeted and untargeted analyses, since it can provide a picture, as complete as possible, of the sample chemical composition [9,11]. From a global perspective, the metabolomic analysis of 1 H-NMR data from fruit extracts showed its ability in assessing the quality and authenticity of plant-based food [12], especially in terms of the botanical and geographical origin, comparison between different growing systems, chemical characterization, and identification of biological active compounds [3].…”

Amino Acid Profile of Fruits as Potential Fingerprints of Varietal Origin

et al. 2019

View full text Add to dashboard Cite

This study aims to assess the capability of the 1 H-NMR profiling of fruits from different genera in combination with multivariate data analysis to provide feasible information for fruit juices' authenticity in terms of botanical origin. Nine fruit varieties from four genera were selected for the experimental plan. The juice obtained from the fruits was characterized using the 1 H-NMR technique, selecting the obtained amino acid profile of fruits as a potential specific fingerprint. Due to the complex information provided by the NMR spectra, a chemometric approach of the data was further applied to enable the differentiation of the fruit samples, highlighting thus its suitability as a discrimination tool for the varietal origin. The advantage of this analytical approach is given by the relatively simple working procedure, which consists of an easy, fast, and accessible preparation stage while providing complex information on fruit composition.
