STUDIES OF PHYSICOCHEMICAL PROPERTIES AND FOOD NUTRIENTS OF SELECTED SEVEN FINE RICE VARIETIES

Abstract

In order to include aromatic rice in the human diet, it is critical to have knowledge about its nutritional content and health benefits. This study examined the nutritional quality features of seven aromatic rice accessions produced in Bangladesh, including proximate composition and mineral concentrations. The accessions studied were Chinigura, Badshabogh, Raduni Pagol, Katari Bogh, Kalijira, BRRI dhan50 and BRRI dhan34. The proximate composition result showed that though the Kalizira local variety showed the highest value for moisture content (13.05%), protein (9.81%) and potassium (245.10 mg/100 g) content while contain lowest fiber, carbohydrate and Sulphur content. BRRI Dhan34 recorded the highest ash (1.55%), fat (0.75%), sodium (239.23 mg/100 g), and phosphorous content (110.64 mg/100 g), while it had the lowest value for the calcium, starch, and sulphur content. The Badshabogh recorded the highest amount of carbohydrate (86.17%), amylose (25.42 mg/100 g), and Magnesium content (951.55 mg/100 g) but had minimum ash, protein, and fat content. BRRI dhan50 had the highest amylose, iron (116.44 mg/100 g), but low in Magnesium content. Radunipagol had the highest fiber (3.96%), starch (28.77%), and calcium (1192.48 mg/100 g), content but lower in ash and sodium content. Chinigura had the top sulphur content (2235.45 mg/100 g). Katari Bogh variety showed the average performance among the studied traits. The nutritional attributes examined in this study were comparable to well-known aromatic rice varieties, indicating their nutritional acceptability. This finding indicated that we could classify these rice varieties as export-quality rice, possessing distinct nutritional qualities that make them desirable for both farmers and consumers in the domestic as well as international market. Among the tested varieties, Randhuni Pagal exhibited the highest content of fiber, starch, calcium, and zinc. BRRI Dhan 34 demonstrated superior levels of ash, fat, sodium, and potassium. Both BRRI Dhan 50 and Bandshavog showed commendable amylose and iron content. In addition to carbohydrates, Bandshavog was noted for its optimal magnesium content. Kalijira stood out for its excellent moisture, protein, and potassium levels. Lastly, Chinigura was distinguished by having the highest sulphur content.
