Abstract

Background: Food fraud is the intentional deception carried out for gain, and is growing. Rice is the most used and the staple cereal for more than half of the world. Because of the scale of the global rice industry, the opportunities for fraud are large, of concern and threat to the economies and health of many. Scope and approach: This review ouylines the complexities of the global rice industry and outlines current frauds. Fraudulent actions can be on many levels such as: botanical and geographical origin, adulteration/substitution, ageing, cultivation practices, aroma/flavour and amounts of microelements. To deal with new rice frauds, the range of techniques to detect them is increasing. Key findings and conclusions: Current research concerning rice fraud is mainly focussed on rice authenticity testing for botanical/geographical origin or cultivation methods. In the case of Mass Specrometry, more advanced techniques are increasingly applied due to their great untargeted analysis power. Spectroscopic techniques can mainly provide screening, but rapid and non-destructive sample analysis, they are cost effective and once established require little expertise. DNA assays are excellent tools to apply for authenticity testing of botanical origin of rice. There is at present, no single analytical tool capable of providing an answer to all rice authentication problems, thus it is necessary to use several approaches in profiling and identification of possible markers and/or adulterants.
