The objectives of this research were to study the suitable formula for the development of dried banana stalk glace and the chemical and physical quality of the products. This research used waste materials from One Banana Company Limited and banana plantation area in Pathum Thani Province. Chemical parameters such as water activity, concentration of syrup (oBrix) and pH and physical quality including color measurement were studied. Sensory quality evaluation, for testing the standard formulas of dried banana stalk, were evaluated by a sample group of 50 non-trained assessors and using the 9-point Hedonic scale. The results showed that the dried banana stalk glace products were formulated with 15 grams of citric acid, 290 grams of sugar per 600 grams of banana stalks content and dried at 90oC for 2 hours. Moreover, the water activity of dried banana stalk glace products was 0.504 (29.7oC). The concentration of syrup was 52 oBrix and the pH of the citric acid solution was 2.20. Finally, the Color L *, a *, b * parameters were 39.8, 9.6, and 16.87 respectively.
