ESTIMACIÓN DE LA VIDA ÚTIL DE UNA FÓRMULA DIETÉTICA EN FUNCIÓN DE LA DISMINUCIÓN DE LISINA DISPONIBLE

This study estimated the shelf life of a dietary formula for children with diarrhea, using the decrease of available lysine as an indicator of deterioration. Product samples were packaged in multilaminal pouches (paper-plastic-foil) and stored at 25, 30 and 35°C, for two months. The available lysine was measured weekly and the reaction of deterioration kinetics and its relationship with temperature was calculated. At the end of the study, the remainder of available lysine was of 38.5 (at 25°C), 15.3 (at 30°C) and 14.1% (at 35°C).The findings of the study indicated a first order reaction ki...
