Formulación de una galleta funcional para el aprovechamiento de las propiedades nutricionales de la harina de chocho (Lupinus mutabilis)

Abstract

Nowadays, the population's perspective on health and nutrition has changed radically due to the growing awareness of diseases resulting from poor nutrition. In this regard, lupin flour (Lupinus mutabilis) emerges as an interesting alternative ingredient for the development of functional foods due to its high protein and fibre content. This study formulated a functional cookie using lupin flour, and analysed the physicochemical, rheological and textural properties of both the flour and the cookie with the best acceptability, after performing a sensory acceptability evaluation and triangulating with the other cookie formulations. The flour revealed high protein (49.58 percent) and total dietary fibre (24.40 percent) content compared to wheat flour. The lupin flour cookie also had a remarkable protein percentage (26.31 percent) five times higher than commercial wheat flour cookies. In the texture analysis, it was found that the lupin flour gave the cookies more hardness and fracturability. Finally, rheological analysis at Mixolab indicated that lupin flour has comparable dough development (120 Nm) and swelling power (0.50 Nm) to wheat flour. The study suggests that the developed lupin flour cookie could be a possible snack alternative for coeliacs with high protein content and a pleasant level of acceptability for all types of consumers.
