Protein, dietary fiber, minerals, antioxidant pigments and phytochemicals, and antioxidant activity in selected red morph Amaranthus leafy vegetable

Amaranth has two morphological types (morphs), one is red and another is green morph. Red morph amaranth is a marvelous source of nutrients, antioxidant pigments, minerals, and phytochemicals compared to green morph amaranth. For this purpose, we selected 25 red morph genotypes to evaluate in terms of proximate, minerals, antioxidant pigments and phytochemicals and antioxidant activity in RCBD design in three replicates. The leaves of red morph amaranth are an excellent source of dietary fiber, carbohydrates, moisture, and protein. We found remarkable potassium, calcium, magnesium (24.96, 10.13, 30.01 mg g-1), iron, manganese, copper, zinc (1089.19, 243.59, 25.77, 986.61 μg g-1), chlorophyll a, chlorophyll b (31.79, 16.05 mg 100 g-1), β-cyanins, total flavonoids (102.10 RE μg g-1 DW), β-xanthins, betalains (33.30,…
