Aplikasi Pati Sagu Termodifikasi Heat Moisture Treatment Untuk Pembuatan Bihun Instan

Abstract

The objectives of this research were to obtain the suitable heat moisture treated sago starch with the best characteristics to be applied for instant bihontype noodles production, and to obtain formula and process to produce the best instant bihon-type noodles. Native sago starch was known to have the type-A pasting profile. This type of sago starch was not suitable to make noodles and pasta products. Heat moisture treatment (HMT) modification would change the pasting profile of starch from type-A to type-B which was more suitable to make noodles. The best result of HMT was modified sago starch with 4 hours heating time. Texturizers were used in order to get better textures of bihon-type noodles. Combination of sodium tri poly phosphate and guar gum gave the best characteristics of product. They were applied into the production of bihon-type noodle made of modified sago starch. There were four different compositions of sago starch used to produce bihon-type noodles, i.e.: 100% native sago starch, mixture of 75% native sago starch and 25% modified sago starch, mixture of 50% native sago starch and 50% modified sago starch, and 100% modified sago starch. The results showed that modified sago starch made cooking time became shorter and decreased the hardness and stickiness of bihon-type noodle textures. The results of sensory evaluation showed that the most prefered bihon-type noodles were made from mixture of 50% native sago starch and 50% modified sago starch.
