Metabolomics as an Emerging Technology for Molecular Authentication of Organic Food Products
Article Sidebar
Main Article Content
Abstract
Nowadays, the popularity of organic agricultural and food products has increased towards trends in healthy food consumption and environmental concerns. At present, organic products are generally sold for much higher values than conventional products and are an attractive target for food fraud malpractices. Therefore, analytical methods for verifying the quality and authenticity of organic products are widely in demand. Metabolomics is recognized as an effective tool for investigating the overall metabolite profile or metabolome of complex biological systems including food matrices. Current studies attempting to assess differences in the metabolite profile of organic and conventional agricultural and food products using various high-throughput analytical platforms in combination with chemometric analysis have been progressively documented. Therefore, this review aims to provide an overview of the studies in which metabolomics approach has been applied for molecular authentication and discrimination between organic and conventional products. The organic food metabolome databases should be further extended and validated in order to apply for organic food authentication and traceability in the future.
