Desarrollo de muffins libres de gluten en base a harina de camote morado (Ipomoea batatas (L.) Lam.) y achira (Canna indica L.)

Abstract

The consumption of products with better nutritional value, reduced fat and sugars, and are gluten-free or lactose-free has gained popularity among consumers in recent years, the Andean crops has been considered because of their nutritional composition and technological properties. The research work was developed with the aim of providing a viable alternative for the use of currently underutilized crops. As part of the research, muffin-type pastry products were developed using purple sweet potato (Ipomoea Batatas (L.) Lam.), and achira (Canna indica L.) flour. The physicochemical, nutritional, textural, and sensory properties of muffins were evaluated. The results showed that the technological and functional properties of the Andean crop flours favored the production of muffin-type pastry products. The sample containing achira flour had the highest protein content (13 percent). The obtained products could be classified as high in dietary fiber if they had values above 3 per cent. According to texture analysis, the achira and purple sweet potato samples showed the highest values of hardness and chewiness; however, these samples were elastic. Sensory evaluation established that the formulation with purple sweet potato flour was the most acceptable because of its color and taste, which were similar to those of chocolate. However, the achira sample was the least appreciated, mainly because of its odor and texture.
