摘要
The present study is aimed at analyzing the antioxidant activity using the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the texture using the Brookfield texture analyzer for blanched-solar dried, blanched-cooled with dehumidification, unblanched-solar dried, and unblanched-cooled with dehumidification mesocarps of two varieties of tender coconut, such as King coconut and Young coconut. Under the different treatments, there was a significant difference in the antioxidant activity and texture parameters such as "hardness" and "chewiness" at 5% level of significance. The highest (421.8 +/- 12.33 mg/L) and the lowest (856.67 +/- 6.72 mg/L) antioxidant activities were recorded for blanched-solar dried mesocarp of King coconut and unblanched-cooled with dehumidification mesocarp of Young coconut, respectively. The texture analysis shows that there is a significant difference in the "hardness" and "chewiness" under different treatments at 5% level of significance. Among the treated mesocarps highest "hardness" value (6619.7 +/- 147.1) and "chewiness" value (1079.3 +/- 54.90) were recorded for King coconut blanched-solar dried mesocarp and lowest "hardness" value (595.67 +/- 36.88) and "chewiness" value (12.634 +/- 0.836) were recorded for Young coconut blanched-cooled with dehumidification mesocarp. Since the blanched-solar dried mesocarp of King Coconut has highest antioxidant activity and lowest "chewiness", it is more suitable to develop a food product.
