Abstract:

Nutritional components in brown rice and ordinary milled rice was determined and compared to evaluate their nutritional values. Results showed that nutritional value of brown rice was higher than that of ordinary milled rice. The hardness of ordinary milled rice was higher than that of brown rice through the examination by texture analyzer. The gel strength of ordinary milled rice powder was higher than that of brown rice powder through the determination by dynamic rheometer. In addition, thermal properties of brown rice powder and ordinary rice powder were also analyzed using differential scanning calorimeter. The gelatinization temperature of brown rice (68.6 ℃) was higher than that of ordinary milled rice (62.4 ℃). The retrogradation of cooked milled rice powder (17210 Pa) was more obvious than that of brown rice powder (11350 Pa) while cooled at 20 ℃.

Key words: brown rice, milled rice, nutritional components, textural property
