[Development of a high content protein beverage from Chilean mesquite, lupine and quinoa for the diet of pre-schoolers]. / Desarrollo de una bebida de alto contenido proteico a partir de algarrobo, lupino y quinoa para la dieta de preescolares.

This research was aimed at developing a high content protein beverage from the mixture of liquid extracts of a pseudocereal, quinoa (Chenopodium quinoa Willd) and two legumes: mesquite (Prosopis chilensis (Mol.) Stunz) and lupine (Lupinus albus L.), native from the Andean highlands of the Chilean northern macro-zone, flavored with raspberry pulp, to help in the feeding of children between 2 and 5 years of lower socioeconomic status with nutritional deficiencies. The formulation was defined by linear programming, its composition was determined by proximate analysis and physical, microbiological and sensory acceptance tests were performed. After 90 days of storage time, the beverage got a protein content of 1.36%, being tryptophan the limiting amino acid; for its part, the chromaticity coordinates of CIEL*a*b* color space showed no statistical significant differences (p < 0.05) maintaining the "dark pink" tonality, the viscosity and the sensory evaluation were acceptable for drinking.

En la presente investigación se desarrolló una bebida de alto contenido proteico a partir de la mezcla de los extractos líquidos de un pseudocereal, quinua (Chenopodium quinoa Willd) y de dos plantas leguminosas: algarrobo (Prosopis chilensis (Mol.) Stunz) y lupino (Lupinusalbus L.), provenientes del altiplano andino de la macro zona norte de Chile, saborizándose con pulpa de frambuesa, para contribuir en la alimentación de niños entre 2y 5 años de estrato socio-económico bajo con deficiencias nutricionales. La formulación se definió por Programación Lineal, se determinó su composición por análisis proximal y se realizaron pruebas físicas, microbiológicas y de aceptación sensorial. Al concluir los 90 días de almacenamiento la bebida obtuvo un contenido de proteínas de1,36%, siendo el triptófano el aminoácido limitante; por su parte, las coordenadas de cromaticidad del espacio de color CIEL*a*b* no presentaron diferencias significativas (p < 0,05) manteniéndose la tonalidad de "rosado oscuro", la viscosidad y la evaluación sensorial resultaron aceptables (AU)
