Abstract
The purpose of the research was to determine the effect of blanching methods to the characteristics of dried bananas. The research method is carried out in three stages, namely the first stage of research, the second stage of research and the third stage of research. The first stage of the research aims to determine the water content, reducing sugar content, vitamin C content and browning index in the raw material. Then in the second stage aims to determine the type of banana and the best freezing time with the hedonic test method. After that, proceed to the third stage of research by determining the selected sample using the hedonic test method, chemical analysis (water content, reducing sugar content, vitamin c content and browning index) and physical (hardness). The results of the first stage of the research showed that ustrali banana water content was 63,46%, nangka banana was 58.60% and kepok banana was 64,04%. The reducing sugar content of ustrali banana was 1,27%, nangka banana was 11.36% and kepok banana was 3,80%. The vitamin C content of ustrali banana was 260,94 mg vit C / 100 g sample, nangka banana was 90.60 mg vit C / 100 g sample, and kepok banana was 40,99 mg vit C / 100 g sample. And the browning index of ustrali banana was L = 85,66; a = 3,11; b = 22,33, nangka banana was L = 81.48; a = 2.95; b = 22.26 and kepok banana was L = 85,15; a = 2,32; b = 19,16. The results of the second stage showed that the selected sample was a1b1 (ustrali banana with 6 hours freezing time). The results of the third stage showed that the selected sample was a3 (citric acid - steam blanching).
