Glycemic Indices of Kale Leaves Based Chakli and Twisters on Normal Human Subjects

The aim of present study was to develop kale based food products by utilizing its powder as an ingredient and to determine glycemic index and glycemic load on normal human subjects through IAUC (Incremental Area Under Curve) method. The food products (chakli and twisters) were developed by incorporation of different proportioned at 5 %, 10 %, 15 % and 20 % of kale powder. The products 5 % kale chakli and 10 % kale twisters were most acceptable by sensory panel while comparing to other variants. Further study was conducted on 30 normal healthy human subjects who were fed best selected test products and anticipated for fasting and post prandial blood glucose level at different intervals (0, 30, 60, 90 and 120 min). The data indicated that blood glucose level of test kale chakli and twisters were significant increased (P 0.05) by 14 % and 8 % respectively at 60 min while these values were significantly decreased by 21 % and 7 % respectively at 120 min when compared with 60 min. The IAUC value was low in both 5& 10 % kale chakli and twisters (1612.2 and 1544.2 mg. min/100ml) when compared to control (3324.5 mg. min/100ml). The data revealed that GI (46.44) and GL (14.5) were found to be low in 10 % kale twisters when compared to 5 % kale chakli which belong to low GI and moderate GL category. Thus, kale possesses nutritional and health benefits which could be competently used in the management of diabetes mellitus.
