Abstract

Characteristics of Rice Analogue, the product resembles to ordinary rice (rice analog), are evaluated using the variation of raw material composition, i.e. Mocaf, green beans flour, and purple corn flour. Rice Analogue is produced by using cold extrusion technology. The product is then analyzed based on its physical, chemical, and sensory properties. The experimental design used 3 treated with a ratio of J1 : Mocaf 60% + green beans flour 20% + corn purple flour 20%, J2 : Mocaf 50% + green beans flour 20% + corn purple flour 30%, J3 : Mocaf 40% + green beans flour 20% + corn purple flour 40%. To get the exact formula and favored by consumers, the comparison is done organoleptic test for flavor, aroma, color and texture then performed physical analysis of gelatinization temperature and density Kamba. The results show that the most preferred formula is J3 which is the ratio: Mocaf 40% + green beans flour 20% + corn purple flour 40%. Physical analysis in Kamba density of 0.497 g/ml, and gelatinization temperature of 100 oC with a time of 3 minutes. And the Chemical analysis results are: 8.60% moisture content, ash content of 1.52%, 11.34% protein content, fat content 1.52 %, 73.62 % starch content, and rice analogue possess anthocyanin 27.15 CyE/g.
