Abstract

This study was conducted to analyze nutrient composition of a genetically modified β-carotene biofortified rice (GM rice), developed by the Rural Development Admistration in Korea. The nutritional constituents of GM rice were compared with those of the parental rice cultivar ’Nakdong’ as a non-GM control to access nutritional equivalence. Proximate components (moisture, starch, protein, lipid, and ash) of the GM rice were similar to those of the conventional non-GM rice. β-Carotene contents of GM brown and milled rice were 2.35, 2.03 ㎍/g (d.b.), respectively. There were no significant differences between the GM and non-GM rice with respect to most of their nutrient composition, despite minor differences in most amino acids and minerals. This result demonstrated that the nutritional composition of this GM rice would be equivalent to that of the parental non-GM rice without major changes in its chemical contents.
