Detection of betacyanin in red-tube spinach (Spinacia oleracea) and its biofortification by strategic hydroponics.

ABSTRACT: Betacyanins have been reported as water-soluble, nitrogenous pigments found in the order Caryophyllales, and they are known for powerful natural antioxidant. The biofortification of secondary metabolites such as anthocyanins and betacyanins has recently been performed in food crops by metabolic engineering through genetic modification. However, the distribution of genetically modified foods is strictly regulated. Therefore, we aimed to develop a new method for biofortifying natural antioxidants, betacyanins, without genetic modification. We first detected the presence of betacyanins in red-tube spinach (Spinacia oleracea) through ultraviolet-visible spectroscopy and mass spectrometry. We then hydroponically cultivated plants in the presence of three candidate compounds for betacyanin biofo
