[Digestibility and protein quality of quinua: comparative study of quinua (Chenopodium Quinoa) seed and flour in children].

Based on the hypothesis that the digestibility of quinua seed is the limiting factor in the utilization of nutrients from this staple, two quinua-based diets were prepared using quinua seeds and quinua flour. Theses diets were offered to children recovering from malnutrition. The digestibility and protein quality of the quinua diets were compared to those of a casein control diet by analyzing the children's metabolic balance. Results showed that digestibility of the quinua diets were compared to those of a casein control diet by analyzing the children's metabolic balance. Results showed that digestibility of the quinua seed is the limiting factor in the protein and energy utilization, and that milling improves significantly the digestibility of fat and carbohydrates. Findings also confirmed that the protein quality of quinua seeds is adequate for human consumption.
