PUA, Amparo L.; BARRETO, Genisberto E.; ZULETA, José L.  and  HERRERA, Oscar D.. Nutrient Analysis of Taro Root (Colocasia esculenta Schott) in the Dry Tropics of Colombia. Inf. tecnol. [online]. 2019, vol.30, n.4, pp.69-76. ISSN 0718-0764.

The aim of the study was to analyze the nutrient content of the taro cultivated in rural areas of the Colombian Caribbean. To the samples of taro, proximal analyzes of vitamins and minerals were carried out, using the Kjeldahl, Soxhlet methods, acid-base hydrolysis, incineration, chromatography and atomic absorption. The results were compared with the nutrient content of sweet potato, potatoes, cassava and yams. The results obtained were 24.99% protein, 0.53% fat, 59.36% carbohydrate, 7.65% ash, 4.88% crude fiber, 2.59% moisture, 8.35 mg / kg of iron 94.45 mg / kg calcium 242.37 mg / kg magnesium, 6.21 mg / kg of zinc, 0.188 mg / 100 mg of vitamin C, 0.047 mg / 100 mg of vitamin B1, and 0.078 mg / 100 mg vitamin B3. The content of proteins and fats was higher than the other vegetables compared.

Keywords : chemical composition; carbohydrates; minerals; chromatography; spectrophotometry.
