title: [Development of a high content protein beverage from Chilean mesquite, lupine and quinoa for the diet of pre-schoolers].
abstract: 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.
