Optimization of liquefaction technology parameter of corn starch by response surface methodology
摘要
Abstract
The optimistic parameters of liquefaction in the key technology of producing corn starch were studied by ternary quadratic regression model and inverse matrix analysis. It was established by contrast analysis of single factors and central composite design. The DE value and refractive index were measured as indexes to determine the liquefaction condition of corn starch which was enzymolysised bya-amylase bearing high temperature. The research showed that there was a significant differences in ternary quadratic regression model which was Y=13.62+0.27X1+0.80X2+1.52X3-1.84X12-0.84X22-0.29X32+0.032X1X2-1.55X1X3+1.08X2X3(P=0.000 3)with coefficient of determination as 0.965. It was indicated that the true DE value of corn starch liquefaction near to 13 mostly while the anticipant DE value was 13.002 2 when the parameters as temperature 79.21 ℃,concentration of starch 18.38% and dosage of amylase 19.98 U/g.关键词
