Abstract

Indonesian is the greatest consumer of rice in the world. Their dependence on rice would bother national food security. The availability of artificial rice made from local materials is expected to overcome food security problem. Cassava and corn flour with glutinous rice flour addition as binding agent expected could produce good properties of artificial rice. This research used Modified Cassava Flour (MOCAF) to replace cassava flour. The experiment divided two levels and every level used factorial design with one factor. There were two levels which glutinous rice flour addition was factor in the first level and MOCAF and corn flour composition was factor in the second level. The best values of physical characteristic in the first level are 0% of glutinous rice flour addition with swelling power 94,16%, rehydrating power 73,73%, lightness 84,59, and chrome 28,14, also 20% of glutinous rice flour addition with dispersed material value 5,60%. Whereas, the best sensory evaluation is 0% of glutinous rice flour with whole hedonic score 4,02. The glutinous rice flour addition would reduce the presentage of dispersed material and reduce score of sensory evaluation. In the second level, the best values of swelling power is 118,57%at 40% of MOCAF, dispersed material is 3,60%at 100% of MOCAF. Whereas the best value of rehydrating power is 77,43% at 0% of MOCAF, lightness 87,16%, and chrome 27,24. The best value of sensory evaluation is 0% of MOCAF with score 4,68. Increasing of MOCAF would reduce dispersed material and reduce score of sensory evaluation.Keywords: artificial rice,starch gelatinyzation, mocaf, glutinous rice flour

Abstract

Making artificial rice is an important step in the framework of the national food security program. Study is divided into two parts, where Research I was varying the time of stirring and Research II was studying aging time. Stirring and aging should be studied because it affects the pragelatinisation process. The results showed that the time of stirring on artificial rice significantly affect rehydration power, dispersed material, and swelling power. While the aging time effect on the brightness, power rehydration, dispersed material, and swelling power. In organoleptic parameters, stirring has no effect on the value, preverences of color, flavor, aroma, appearance, and overall. While the aging time affects the value appearance and overall. Artificial rice which has the most excellent consumer acceptance is that the long treatment of 20 minutes stirring and 3 days aging time. Artificial rice stirring at 20-minute treatment has a brightness value of 52,8; 141,2% power rehydration; dispersed material 4,1%; and swelling power 244,2%. While artificial rice with 3 days aging treatment has the lightness value of 50,9; power rehydration 78,9%; 13,6% dispersed material; 234,3% swelling power.Keywords: artificial rice, MOCAF, pragelatinisation, consumer acceptance
