Quinoa sprouts as potential vegetable source: nutrient composition and functional contents of different quinoa sprout varieties

Abstract Quinoa has a long history of cultivation and unique nutritional value. Quinoa sprouts can be eaten as leafy vegetables, but their nutritional quality is unknown. Ten quinoa sprout varieties (lines) were evaluated and compared for nutrient and functional composition. All quinoa sprout varieties had high contents of moisture content, reducing sugar, potassium, magnesium, and vitamin C. All varieties contained all essential amino acids, with leucine present in abundance. They had high contents of phenolics, flavonoids, carotenoids (β-carotene and lycopene) as well as chlorophylls a and b. Overall, var. LL-01 had better nutrient and phytochemical composition than other varieties. The potential nutritional health benefits of quinoa sprouts as a vegetable are important for both traditional and contemporary diets.
