Abstract

Almojábana is a kind of food that varies in its composition depending on the geographical place where it is baked. In Ecuador, almojábana is based on cheese, wheat flour and Canna edulis starch. C. edulis planting has diminished, leading to a high cost of the starch and less availability on the market. The present work studied C. edulis starch substitution by a mixture of potato and cassava starches on the elaboration of almojábanas. Specific volume, crumb structure, textural properties and sensory analyses were used to find the best starch substitution. Mixtures of cassava and potato starch (25/75, 35/65, and 45/55) and starch dough resting time (10, 15, and 20 h) were investigated. Hardness, elasticity, chewiness, specific volume, average size cell, the number of cells per area and the total area of cells of almojábanas were determined. Results showed that a mixture of 25% potato, 75% cassava and 20 h resting time could substitute C. edulis starch in almojábana baking. The obtained almojábanas had different flavor compared to a control sample (based on C. edulis starch). Starch substitution reduced the cost of raw materials (starch) by 60%.

在almojábanas的生产中，美人蕉淀粉代替马铃薯/木薯淀粉的混合物

Almojábana是一种食物，其成分因其烘焙地的地理位置而异。在厄瓜多尔，almojábana是由奶酪、小麦粉和美人蕉淀粉制成的。毛竹种植减少，导致淀粉成本高，市场上的供应量减少。本文研究了马铃薯淀粉和木薯淀粉的混合物对甜菜淀粉的替代作用，并对almojábanas进行了阐述。通过比容、面包屑结构、质构性能和感官分析，找到了最佳的淀粉替代品。研究了木薯和马铃薯淀粉(25/75、35/65和45/55)的混合物以及淀粉面团静息时间(10、15和20 h)。测定了almojábanas的硬度、弹性、耐嚼性、比容、平均细胞大小、每面积细胞数和细胞总面积。结果表明，25%的马铃薯和75%的木薯混合，静置20 h，可以代替甜菜淀粉almojábana烘焙。得到的almojábanas与对照样品(基于C. edulis淀粉)相比具有不同的风味。淀粉替代使原料(淀粉)的成本降低了60%。

期刊介绍： La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
