Resumen

ZHURBENKO, Raisa et al. Influence of the drying parameters on the physicochemical and biological indicators of a protein hydrolisate. Rev Cubana Farm [online]. 2008, vol.42, n.1. ISSN 0034-7515.

The spraying dehydration conditions of a Papaic hydrolisate from an animal muscle were studied, and it was proved that the parameter with the highest direct influence on the apparent density of the powder was the concentration of total solids (43 %), followed by the temperature at the inlet of the chamber (140 °C) and the speed of the atomizer (21 500 rev/min), both in an inverse form. The apparent density reached approximately 400 kg m-3 compared with the obtained before the study of 50 kg m-3. As to the apparent density, better results were obtained on dehydrating the hidrolisate at 122 °C in the inlet of the machine and at 90 °C in the outlet, in comparison with 140 °C in the inlet of the equipment. It was proved that the product obtained had physical, chemical and biochemical characteristics that favored the growth of different microbial species of collection

Palabras clave : Apparent density; spray drying; papaic hydrolysate; total nitrogen; amino nitrogen; promotion of the microbial growth.
