Effect of maturity, position of leaves and post harvest storage on the nutritional composition and organoleptic qualities of amaranthus.

Two cultivars of amaranthus (Amaranthus tricolor, red and green type), were grown during the rainy and summer seasons at Vellayani, Trivandrum. The effect of maturity (10, 20 and 30 days after planting (DAP)), leaf position (apex, middle and base) and postharvest storage (24, 48 or 72 h in the refrigerator, covered with a wet cloth, placed in a polyethylene bag, or the roots put in water) on the nutrient composition and organoleptic quality of leaves were assessed. Ca, Fe and ascorbic acid contents were significantly higher at 20 DAP. Leaf protein content was unaffected by any of the treatments. In both seasons, the green cultivar was more nutritious than the red one. The red cultivar, however, when grown in the summer season, had the better organoleptic quality. Leaves were best stored in the refrigerator for no longer than 24 h, otherwise the ascorbic acid content was significantly reduced.
