Resumen de Sensory Evaluation and Composition of Spaghetti Fortified with Soy Flour
R. L. Shogren, G.A. Hareland, Y.V. Wu
Spaghetti was prepared from durum wheat supplemented with soy flour in order to make an inexpensive, highly nutritious food and to determine the effects of high levels of soy flour on taste and textural attributes. Up to 50% soy flour was incorporated into spaghetti, resulting in a protein content of 33.5% (compared with 15.4% for control without soy) and a lysine content of 1.75% (compared with 0.41% for control). Sensory analysis of enriched spaghetti containing up to 35% soy flour indicated no significant difference in flavor and texture compared with control without soy, in general. Spaghetti with 50% soy flour had slightly higher beany and bitter flavors compared with control. This study showed that a high-protein and high-lysine spaghetti can be made with 35% soy flour without adverse effect on flavor and texture and should result in greater acceptability of soy-based foods.
