KAJIAN PERBANDINGAN KARAKTERISTIK TEPUNG ONGGOK DARI INDUSTRI BESAR DAN INDUSTRI KECIL - Comparison Study of Onggok Flours Characteristics From Large and Small Industries

摘要

The by-product of tapioca industry is liquid waste and solid waste ( onggok ) . There are several types of onggok that suitable for raw materials of various foods. This research aimed to show that the differences in cassava processing techniques into tapioca in large and small industries w ould produce different types of onggok flour. The differences in characteristics between the two types of onggok were known through testing of water content, ash content , crude fiber, acid degree, starch content and whitene s with consecutive results of 8.84%, 0.71%, 6.77%, 1.35%, 72.43% and 82.1% for small-scale industries. Test results of onggok flour from large industries were 4.25%, 8.18%, 21.27%, 0.87%, 48.71% and 24.1%. The results of mold testing for onggok from small industries and large industries were 1 colony/gram and 250 colonies/gram respectively , while the total plate numbers were 1,700 colonies/gram and 3,300 colonies/gram. Onggok flour made in small industries size was 8-19 m m seen through SEM, while the measurement results with Amylo-graph brabender showed maximum viscosity 999 BU. Onggok flour in small industries has different characteristics with large industries, such as higher starch content, and gelatinization patterns similar to tapioca so that it can be used further to make snacks.
