【 摘 要 】

This research was aimed to analyze the chemical, physical, and sensory characteristics of the analog rice developed from a composite formula consisting of mocaf, arrowroot, and red bean flour. Experiment was designed into 5 different composition types i.e B1(90%: 0%: 10%), B2(80%:10%: 10%), B3(70% : 20% : 10%), B4(60%: 30%:10%), and B5(50%: 40%: 10%) which in each type was repeated in 4 times. Carrageenan was used as a binder in the making process of those analog rice. Investigation procedure was carried out into several stages such as preparation and characterization of raw materials, production of analog rice in composite formula, then the testing of its chemical and sensory properties. Chemical characteristics were evaluated about the level of starch, amylose, dietary fiber, and resistant starch while sensory characteristics were examined about the texture, flavor, and aroma. The result showed that based on the sensory test, the best composite formula of rice analog was B2(ratio flour of mocaf: Arrowroot: Red bean = 80:10:10). In addition, B2formula possessed the chemical characteristics similar with the truth rice either in water content (12.18%), ash (2.63%), protein (6.17%), fat (1.31%), carbohydrate (89.88%), starch (73.29%), amylose (24.91%), total dietary fiber (7.04%), or resistant starch (6.71%). Furthermore, the higher of arrowroot flour proportion, the greater of amylose, dietary fiber and resistant starch containing in the rice analog. In the opposite, its starch content was getting down.
