Background: Several speciality rice with health claims are emerging in the south Indian market. The study aims to examine the nature of speciality rice with health claims available in the Chennai market. Methodology: A market survey was conducted in randomly selected outlets from 4 zones of the Chennai city urban market (100 stores including supermarkets/hypermarkets/departmental stores/pharmacies were visited and rice samples were collected). The product label information, claims declared on the pack and morphological features of the rice samples were examined and recorded using stereo-zoom microscope. Results: Fifteen rice samples of different categories including whole-grain rice (8), semi-polished rice (2) and polished white rice (5) were evaluated. Three samples had low-glycaemic index claims among whole-grain rice and 2 among polished white rice. The health claims were not supported with scientific evidence and were sometimes misleading as revealed by stereo-zoom microscopic examination. Conclusions: The authenticity of many of the health claims declared on the rice packs is questionable due to the lack of scientific evidence. The awareness about the quality of rice would be helpful for the consumer to make a wise choice about which cereal staple to purchase.
