- Postharvest characterization of seven arracacha cultivars ( Arracacia xanthorrhiza Bancroft) Mayra Rincón Hernán Ruiz Julián Molano Javier Álvarez-Herrera Liney Pinto Agrociencias Starch Storage Firmness Tuberous roots Respiratory rate Arracacha is used by farming families as a fundamental crop for food security because of its caloric content. In Colombia, there are diverse cultivars that have been scarcely studied. The postharvest quality and starch content of seven arracacha cultivars were characterized. A completely randomized design was used with seven treatments, consisting of the cultivars 'yema de huevo', 'paliverde', 'palirrusia', 'yucatana', 'blanca de tarro', 'palinegra' and 'amarilla de tarro'. The results showed that the pH, the total soluble solids, and the maturity ratio increased for all cultivars except for 'palinegra' during the first 8 days after harvest. The total titratable acidity decreased for 'amarilla de tarro'; in the rest of cultivars, there was a slight increase over time. The respiratory rate and firmness increased in all cultivars until day 12, with higher values for 'palinegra'. Starch content, respiratory rate, and firmness decreased, while L* increased. The loss of mass had the highest values in the first 3 days of storage. The color index and the L* and b* parameters increased over time; therefore, increases in luminosity and yellow colorations were observed. 'Paliverde' showed the highest starch content, being the cultivar less suitable for industries. 2021 artículo científico 0304-2847 https://www.redalyc.org/articulo.oa?id=179969339014 https://www.redalyc.org/journal/1799/179969339014/ https://www.redalyc.org/journal/1799/179969339014/html/ https://www.redalyc.org/journal/1799/179969339014/179969339014.epub https://www.redalyc.org/journal/1799/179969339014/movil 10.15446/rfnam.v74n3.92658 en http://www.redalyc.org/revista.oa?id=1799 Revista Facultad Nacional de Agronomía - Medellín application/pdf Universidad Nacional de Colombia Revista Facultad Nacional de Agronomía - Medellín (Colombia) Num.3 Vol.74
