据了解，这种转基因大米源自转基因水稻品种GR2E，经过转基因技术改进后，大米中维生素A原（主要为β-胡萝卜素）含量大幅增加。发展中国家种植该水稻，有助于降低维生素A缺乏症的发病率。

    Food Standards Australia New Zealand （FSANZ） received an Application from the International Rice Research Institute on 16 November 2016. The Applicant requested a variation to Schedule 26 in the Australia New Zealand Food Standards Code （the Code） to include food from a new genetically modified （GM） rice （Oryza sativa） line, GR2E. This rice line has been genetically modified to produce beta （β）-carotene （the predominant form of provitamin A） and other minor provitamin A carotenoids in the endosperm of the rice grain.

 

    GR2E is a new food crop designed to mitigate vitamin A deficiency in developing countries. GR2E is not intended to be used in the Australian or New Zealand food supplies. Approving this crop will prevent trade disruption should GR2E be inadvertently present in imported shipments of milled rice.
