Description
Summary:•Food fingerprints as tool to monitor the foodstuffs authentication.•Put forward the biomarker candidates to guarantee the food authenticity and safety.•Summarize biomarkers in response to geographical, genetic or human alterations.•The biomarkers identification is crucial to avoid food frauds.•Authentication biomarkers databases need to be generated. In recent years, food frauds and adulterations have increased significantly. This practice is motivated by fast economical gains and has an enormous impact on public health, representing an important issue in food science. In this context, this review has been designed to be a useful guide of potential biomarkers of food authenticity and safety. In terms of food authenticity, we focused our attention on biomarkers reported to specify different botanical or geographical origins, genetic diversity or production systems, while at the food safety level, molecular evidences of food adulteration or spoilage will be highlighted. This report is the first to combine results from recent studies in a format that allows a ready overview of metabolites (
