Abstract: Objective: To determine the nutrients and quality of red bud taro (Colocasia esulenla (L.) Schott). Methods: The nutritional value and ingredients of red bud taro were examined and evaluated according to relevant national standards. Results: The contents of crude protein, crude fat, crude fiber, starch, ash and water in red bud taro were 2.18%, 0.096%, 1.37%, 13.40%, 0.76% and 82.88%, respectively. The contents of carotene, ascorbic acid, thiamine and riboflavin were 7.714, 0.069, 0.117 mg/100g and 0.204 mg/100 g, respectively. The contents of mineral elements K, P, Ca, Mg, Na, Fe and F were 95.87, 23.88, 7.92, 3.60, 0.10, 0.06 mg/100 g and 9.93 × 10-3 mg/100 g, respectively. The contents of essential (EAA), non-essential (NEAA), and total amino acids (TAA) were 39.87%, 56.37% and 96.24%, respectively. The amino acids score (AAS), chemical score (CS), and essential index (EAAI) were7.38, 5.47 and 56.12, respectively. Additionally, the EAA/TAA and EAA/NEAA ratios were 41.43% and 70.73%, respectively. Moreover, the content of flavor amino acids was 40.43% based on total amino acids. Conclusion: Red bud taro is rich in carbohydrates, proteins, vitamins and mineral elements and low in fat so that it reveals high edibleness and great development prospects.
