Abstract

Physiological changes in bananas ripened by the traditional practice of smoking for 24 to 36 h and subsequent storage at room temp., were investigated. It was found that banana tissue in smoked fruit contain 50-100% more CO2 compared to that of unsmoked bananas. The colour of the smoked sample changed from green to yellow in 5 days compared to the unsmoked sample which took 7 days. The fruit in the smoked group became edible, ripe and soft in 7 days whilst the fruit in the unsmoked group was yellow and hard even on the 8th day. The pulp/peel ratio increased from 1.45 to 2.50 in the smoked samples as against 1.45 to 2.21 in the unsmoked samples. The non-reducing and total sugars showed higher values in the smoked samples and the heat of respiration at the climacteric peak in smoked fruit was 21 340 Btu/ton/24 h while unsmoked fruit gave 17 600 Btu/ton/24 h. Reducing sugars did not show any appreciable difference.
