Abstract

GELATIN is a protein hydrocolloid. Because of its unique characteristics such as gel forming, thickening, stabilizing, emulsifiing, foam and film forming, is widely used in food industries. In this research, in order to optimize the factors which affect ENZYMATIC EXTRACTION method of GELATIN,the effects of three variables, enzyme concentrations (2-10 ppm), time (8-16 hours) and temperature (60-80oC) on the yield of extraction, gel strength, viscosity and absorption in 420 nm were investigated. The rotatable central composite experimental design was used, and the data were analyzed by using of response surface regression (RSREG).Correlation coefficients of fitted regression models of yield, gel strength, viscosity and absorption for enzyme extraction method were determined as 0.953, 0.998, 0.995 and 0.935, respectively.Analysis of variance for the overall effects of process variables in ENZYMATIC EXTRACTION method on regression models showed that the enzyme concentration, the time of enzyme treatments and temperature had significant effects on gel strength and viscosity regression models, however the effect of temperature on both yield and absorption regression models was not significant (p>0.05). The optimum conditions obtained from response surface regression models in ENZYMATIC EXTRACTION method for yield, gel strength, viscosity and absorption which were verified experimentalls were (6.1 ppm, 15.6 hours, 70oC), (9.1 ppm, 11.9 hours, 70.3oC), (7.86 ppm, 14.9 hours, 77.5oC) and (2.8 ppm, 10 hours, 60oC), respectively.
