Golden rice is a form of rice with biosynthesis of beta-carotene (a form of vitamin A). In other words, golden rice is produced through genetic engineering. Beta-carotene gives golden rice its “golden” or “yellow” coloring. White rice, on the other hand, does not contain carotenoids (i.e. beta carotene) and therefore lacks that “golden” coloring. When you consume golden rice, the beta-carotene either accumulates in your fatty tissues or is transformed into vitamin A.
