    BIOCHEMICAL STUDY ON TRADITIONAL RICE PRODUCTS OF ASSAM WITH SPECIAL REFERENCE TO RESISTANT STARCH
    (AAU, Jorhat, 2017-07) Banik, Rajesh; Das, Priyanka
    Rice is the most important food crop of the world after wheat. South East Asian countries are heavily reliant upon rice for their dietary energy supply. 70% of total arable agricultural land of India lies under the rice cultivation. In North Eastern region, rice is the main staple food and in Assam there are several traditional rice based processed products which are also largely used as food. These are bhoja chaul, sandah guri, korai, popped rice, flaked rice, puffed rice, komal chaul (soft rice) and hurum. The moisture content, on wet basis varied from 5.83-11.61%. on dry weight basis, the crude protein content of different rice products ranged from 7.74-9.40%, the lowest in puffed rice and the highest in popped rice. The total ash content was determined on dry weight basis and it ranged in between 0.61-4.33%. The crude fiber percentage was the highest (1.04%) in bhoja chaul and sandah guri and the lowest (0.63%) in popped rice. The crude fat content is the lowest in hurum (0.11%) and the highest in korai (0.31%). The total carbohydrate percentage of these traditional rice products ranged between 49.33-67.55% and the highest in sandah and the lowest in flaked rice. The total starch content (on dry weight basis) was found to be the highest (58.08%) in popped rice and the lowest (39.37%) in korai, whereas, the resistant starch content was found to be highest (5.42%) in sandah and the lowest (3.24%) in puffed rice. The present study indicated that the rice based traditional processed products of Assam are good sources of carbohydrate, proteins and crude fiber. The said products are having good amount of resistant starch, which is very much useful for the better health. In future, further studies are required for the determination of other nutrients such as different micronutrients, and physical properties of the rice based traditional products of Assam, that may reveal useful information for the human health.
