Description
Driven by their prominent health benefits, mushrooms are extremely popular in food and nutraceutical sectors, incidentally attracting food fraud such as species mislabeling and substitution, adulteration, and contamination with synthetic and cheaper substitutes, severely affecting the supply chain and raising concerns among consumers about product safety and quality. Untargeted chemical profiling using Nuclear Magnetic Resonance (U-NMR) spectroscopy, in conjunction with Multivariate Statistical Analysis (MSA) proves to be a superior and universally recognized analytical method in simultaneously addressing these concerns and inadequacies of conventional analytical methods. A comprehensive and robust 1H NMR spectral library is built using validated mushroom samples of different species and product types (extracts, fruiting body, pure mycelium, mycelia on grain, multi-species blends, etc..) and is employed for species authentication and product verification through U-NMR and MSA. Clear assignments of species identification and product verification are achieved, and products with non-conforming chemical fingerprints are identified, attributable to the food fraud aspects listed above. In addition to these examples, the applicability of NMR metabolomics in ensuring the authenticity of mushroom products throughout the supply chain and measures to address food fraud are discussed.
