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.

Summary

Introduction

Dependence on rice has become a major problem with the increasing population of Indonesia because it is not offset by increased rice production. The increase in population is in line with the increase of national rice consumption. This prompted the Government of Indonesia to import 1.92 million tons of rice by 2014[1]. The high import of rice indicates that domestic production has not met the food needs of Indonesians. This factor encourages the diversification of non-rice food. Diversification of staple food consumption is one effort to maintain food security. The diversification of staple food consumption is not intended to replace the total rice but to change the food consumption pattern of the people, so that the society does not depend on one type of staple food[2]
