Teknologi Proses Ekstrusi untuk Membuat Beras Analog (Extrusion Process Technology of Analog Rice)

Abstract

Indonesia rice consumption level is very high and up to 139 kg/capita/year, higher than that of average consumption level in South East Asia, so that import of rice is frequently needed to fill the need of population. Indonesia is actually rich in local food sources other than rice; such as corn, sorghum, cassava, sago, etc. but they are not as popular as rice. Therefore technology for the production of analog rice using the localbased non-rice food sources is needed. Extrusion technology has been used to produce analog rice from broken rice as its raw material. Recently; extrusion technology has also been used to develop analog rice using non-rice food material. The characteristic of analog rice which is similar with the natural rice could be achieved by controlling the critical extrusion parameters, such as the characteristics and composition of raw material, the temperature of extrusion, the speed of screw etc. The success of the analog rice production from the non rice food material will open up opportunities for fortification program using analog rice as a carrier for the nutrient target. This paper reviews the research reports for analog rice production with extrusion technology using variety of raw materials; including broken rice and the non-rice food material, with and without fortification.
