RESUMEN
La calidad proteica de los cultivares de cebada Esmeralda 1, M16, Pastor Ortíz del Estado de Hidalgo y M16 del Estado de Tlaxcala fue evaluada por la determinación de la relación de eficiencia proteica (PER), basándose en el incremento de peso de ratas alimentadas con dietas bajo condiciones estandarizadas. Se observó que no existen diferencias significativas entre las cuatro variedades estudiadas, es decir, que las cuatro variedades proporcionan la misma calidad proteica al organismo, oscilando los valores de PER entre 2.4-2.2. Con relación a la caseína hubo una diferencia marcada, ya que dicha proteína produce mayor incremento de peso que las variedades de cebada. Esta diferencia entre las proteínas de caseína y las proteínas de cebada se debe al contenido de aminoácidos esenciales.
ABSTRACT
The protein quality of plantations of Esmeralda 1, M16, Pastor Ortíz barley varieties in Hidalgo state and M16 variety in Tlaxcala state were evaluated by means of the determination of protein efficiency relation (PER), being based on the increase of weight of rats fed with diets under standard conditions. It was observed that significant differences between the four varieties studied do not exist, that is to say, that the four varieties provide the same protein quality to the organism, having oscillated the values of PER between 2.4-2.2. In relation to the casein, there is a marked difference, since this protein provides greater increase of weight than the varieties of barley. This difference between casein proteins and barley proteins is due to the content of essential amino acids.
