摘要：A 32full factorial design was used to optimize the experimental conditions of demineralization of sardine scaleswithout loss collagen in hydrolic acid. Critical parameters such as hydrolic acid concentration (X1,M) andreaction time (X2,h) were studied to evaluate their effect on yield of demineralization (Y1,%) andhydroxyproline content (Y2,%). Two regression models of these variables (X1 and X2) were adopted with theresponse values (Y1 and Y2). The results obtained showed that the optimum demineralization conditions were:hydrolic acid concentration of 0.1M and reaction time of 24h. These conditions led to 99.26% ofdemineralization and 0.1% of hydroxyproline content.
