Analog Rice Development as Alternative Food Made of Raw Composite Flour Enriched Protein Canavalia ensiformis

Abstract

Food is an important factor in human life. Indonesia’s main food need is rice. Domestic rice demand continues to increase along with population growth. One of the businesses that can increase the availability of food, especially rice, is to utilize the existing agricultural products even though they have not been utilized economically and intensified the excavation of new food sources. Analog rice is a form of food diversification by utilizing local carbohydrate sources. In this study analog rice made from composite flour mixture of cassava flour, Dioscorea esculenta L, corn enriched with protein Canavalia ensiformis. The purpose of this research is to develop the method of production of analog rice and to test the physicochemical properties including water content, water, protein, and amylose so that it can be applied as food substitute for rice in realizing Indonesia food security program. The largest protein content of 9.156%, the highest water content of 12.431%, water absorption 187%. The amylose content of analog rice amounted to 19.677% included in the low-octane rice.
