Abstract

Indonesia is one of the world's largest wheat importer, some research are conducted to find other carbohydrate sources which can replace wheat. Cassava is very easy to find and grown in tropical climates especially Indonesia. The research is focused on cassava starch modification as a substitute for wheat flour in order to reduce consumption of wheat flour. The aim of this research is to assess the effect of temperature, pH, and the concentration of H2O2 in modifying cassava starch which. The combination methods are lactic acid hydroxylation and hydrogen peroxide oxidation to improve baking expansion. The carboxyl group, carbonyl group, swelling power, starch solubility, and baking expansion of starch are analized and calculated. Results showed that the modified cassava starch can substitute wheat flour with optimum conditions process at a concentration of H2O2 is 1.5% w/w, oxidation temperature is 50°C, and pH is 3 by the value of swelling power is 6.82%, solubility is 0.02%, and baking expansion is 7.2 cm3/gram.
