Karakteristik Beberapa Sifat Fisikokimia Dan Sifat Pasta Pati Sagu Yang Dimodifikasi Dengan Lactobacillus Plantarum 1

Research has been conducted on microbiological modification of sago starch using lactic acid bacteria (LAB) obtained from sago starch processing industry. The aim of this research was to compare some physicochemical and pasting properties of modified sago starch to native sago starch. The treatment in this study were modification by combination of LAB isolates which had different amylolitic ability from high (L. plantarum 1 RN2-12112), medium (L. plantarum 1 RN2-53) and low (L. plantarum 1 RN1-23121), where P0 = native sago starch (without modification), P1 = modified sago starch L. plantarum 1 RN2-12112 : L. plantarum 1 RN2-53 (1:1), P2 = modified sago starch L. plantarum 1 RN2-12112 : L. plantarum 1 RN1- 23121 (1:1), P3 = modified sago starch L. plantarum 1 RN2-53 : L. plantarum 1 RN1-23121 (1:1). The results show that the modification of sago starch with a combination of LAB isolates significantly affected starch content, amylose content and freeze-thaw stability. The pasting profile of native and modified sago starch using rapid visco analyzer (RVA) showed general similarities, but the result of viscosity values were significantly different (peak viscosity, breakdown viscosity, holding viscosity, final viscosity and setback viscosity). Modified sago starch using LAB isolates with high and medium amylolitic (L. plantarum 1 RN2-12112 and L. plantarum 1 RN2-53) ability had better physicochemical properties in product application which requires heating and development. Keywords: amylolytic, Lactobacillus plantarum 1, modification of starch, sago starch
