| Resumo: | In this report a study about experimental condition in a dechroming shavings hydrolytic process al moderate temperature involving an alkaline hydrolysis with calcium and sodium hydroxide with and without the presence of a proteolytic enzyme is described. The percentage of solubilization ol shavings is followed by total solid determination in protein hydrolysates; durability properties and aspect of hydrolysates is evaluated. A pilot plant trial was carried out using the developed procedure, in which a proteins mass balance through total nitrogen contents was perlormed. A statistical design based on a completed factorial experiment with four factors at two levels was employed and a reduced polynomial model from the experimental results was obtained. |
