golden rice was developed to help with blindness caused by a deficiency of which vitamin?
beta - carotene
bullet::::- food fortification is also useful for improving vad. a variety of oily and dry forms of the retinol esters, retinyl acetates, and retinyl palmitate are available for food fortification of vitamin a. margarine and oil are the ideal food vehicles for vitamin a fortification. they protect vitamin a from oxidation during storage and prompt absorption of vitamin a. beta-carotene and retinyl acetate or retinyl palmitate are used as a form of vitamin a for vitamin a fortification of fat-based foods. fortification of sugar with retinyl palmitate as a form of vitamin a has been used extensively throughout central america. cereal flours, milk powder, and liquid milk are also used as food vehicles for vitamin a fortification. genetic engineering is another method that could be used to fortify food, and golden rice is a genetic engineering project designed to fortify rice with beta-carotene (which humans can convert into vitamin a) and thereby prevent and/or treat vad. although opposition to genetically modified foods resulted in the destruction of a field trial of golden rice prototypes in 2013, development of golden rice has proceeded and developers are currently (as of september 2018) awaiting regulatory approval to publicly release golden rice in the philippines.

in 2005, a team of researchers at syngenta produced golden rice 2. they combined the phytoene synthase gene from maize with "crt1" from the original golden rice. golden rice 2 produces 23 times more carotenoids than golden rice (up to 37 µg/g), and preferentially accumulates beta-carotene (up to 31 µg/g of the 37 µg/g of carotenoids).
