The effect of the conditions of puffins on the quality of the physical and sensory qualities of the banana slices. The Phase 3 ripe bananas sweeter 14-18% Brix, cut crosswise size 2.5 mm immersion citric acid at a concentration of 0.75% (W / V) as long as 5 minutes, devided into two parts. through May Retreat Apartments with blanched at 90 ° c for one minute and not the pre-treatment unit. Then dried using hot air oven (hot air oven) at a temperature of 90 ° C to a moisture content of 20 to 25 and 30% db before entering into puffins in order to keep the water inside the restaurant was boiling. vaporize quickly at temperatures of 160 ° c for a period of drying for five minutes at a temperature of 170 ° c for a period in the oven for 4 minutes to final moisture content of 4% db from the property. physical color, the contraction (shrinkage) and the texture and hardness (hardness) of the banana slices. Found that the state did not pass the pre-treatment treatment products banana chips, dried at a temperature of 160 degrees Celsius with the brightness (L *), the red (a *) and yellowness (b. *) higher than the drying at 170 ° c, but in a state of pre-treatment treatment products banana chips, dried at a temperature of 160 degrees Celsius with the brightness (L *), the red (a *). and the yellowness (b *) under the drying at 170 ° c for the pre-treatment and temperature used in the drying affect the shrinkage and hardness of bananas. sheets drying significantly (p <0.05), by-products banana after and did not pass the pre-treatment and dried at a temperature of 170 degrees Celsius, the hardness and the shrinkage less. dried at 160 ° C. the results of evaluating the organoleptic found that banana after going through the pre-treatment and dried at a temperature of 160 ° c, a temperature of 170 ° c, with an average score of. sensory evaluation of the odor and taste of the product, including higher banana after the presentation for treatment (p <0.05).
