The rising prevalence of diabetes is closely associated with industrialization, urbanization, socio-economic development and changes in the life style. The rice varieties namely TRY-3, Black Kavuni and Karungkuruvai were selected for the study based on their popularity, nutritional characteristics and other specific characteristics in Tamil Nadu. Initially the non-diabetic participants were screened by conducting glucose tolerance test by administering glucose powder available in the market dissolved in potable water containing 50g of glucose as reference carbohydrate. For the intervention rice varieties viz., TRY-3, Black Kavuni and Karungkuruvai containing 50g of carbohydrate in the form flakes and provided to the healthy participant. The blood glucose level of the participants before administering test food and during 15th, 30th, 45th, 60th, 90th and 120th minutes were noted and taken for calculating the glycemic index. The Carbohydrate and crude fibre content of TRY-3, Black Kavuni and Karunkuruvai were 70.23g and 0.99g, 62.89g and 1.70g and 63.09g and 2.01g, respectively. The Consumer acceptability of TRY-3 was high than Black Kavuni and Karunkuruvai with values are 8.7, 8.1 and 7.8, respectively. The recovery percentage of Black Kavuni was high than Karunkuruvai and TRY-3 with values are 58 per cent, 55.2 per cent and 53.5 per cent, respectively. In the present study the Glycemic index of black kavuni (53.10) is lesser than karunkuruvai (55.50) which are in the low Glycemic foods. TRY 3 has a G.I. of 68.20 which is higher Glycemic index than traditional varieties.

Abstract


The rising prevalence of diabetes is closely associated with industrialization, urbanization, socio-economic development and changes in the life style. The rice varieties namely TRY-3, Black Kavuni and Karungkuruvai were selected for the study based on their popularity, nutritional characteristics and other specific characteristics in Tamil Nadu. Initially the non-diabetic participants were screened by conducting glucose tolerance test by administering glucose powder available in the market dissolved in potable water containing 50g of glucose as reference carbohydrate. For the intervention rice varieties viz., TRY-3, Black Kavuni and Karungkuruvai containing 50g of carbohydrate in the form flakes and provided to the healthy participant. The blood glucose level of the participants before administering test food and during 15th, 30th, 45th, 60th, 90th and 120th minutes were noted and taken for calculating the glycemic index. The Carbohydrate and crude fibre content of TRY-3, Black Kavuni and Karunkuruvai were 70.23g and 0.99g, 62.89g and 1.70g and 63.09g and 2.01g, respectively. The Consumer acceptability of TRY-3 was high than Black Kavuni and Karunkuruvai with values are 8.7, 8.1 and 7.8, respectively. The recovery percentage of Black Kavuni was high than Karunkuruvai and TRY-3 with values are 58 per cent, 55.2 per cent and 53.5 per cent, respectively. In the present study the Glycemic index of black kavuni (53.10) is lesser than karunkuruvai (55.50) which are in the low Glycemic foods. TRY 3 has a G.I. of 68.20 which is higher Glycemic index than traditional varieties.
