Breakfast cereal plays an important role in a balanced diet. In Malaysia, tons of highly nutritious banana peels, overripe, oversupplied and rejected bananas end up in food waste, as a result of high production and consumption of banana. Thus, this study aimed to produce flaked breakfast cereal with banana pulp, banana peel and cornmeal through oven -baking. Baking temperature, baking time and volume of banana pulp and peel mixture were optimized by using response surface methodology (RSM) to achieve desired fracturability and yellowness. Through this study, fracturability (R2 = 0.98, P≤0.05) and yellowness (R2 = 0.99, P≤0.05) were found to be significantly related to the processing parameters and formulation of the flakes. The optimum processing parameters and formula obtained from this study were the baking temperature of 129.5°C, baking time of 15 mins and volume of banana pulp and peel mixture of 140 g. Besides, a sensory evaluation was conducted and compared among the optimized flakes and commercial corn flakes. Based on the results, there was a significant difference (P≤0.05) in aroma, appearance and taste but no significant difference (P>0.05) in mouthfeel and overall acceptability between both types of flakes. It was recommended that the shelf-life study of the optimized flakes could be done for future study.

Response surface methodology (RSM) was employed to optimize the extraction conditions of tannins from banana peels. Based on the single-factor experiments, four independent variables including ethanol concentration, solid to liquid ratio, extraction time and extraction temperature were selected as affecting factors. According to central composite design (CCD) the four factor, five levels experiments were carried out with the tannin extraction yield as evaluation index. The results show that the optimized conditions are as follows: ethanol concentration of 75.44%, solid to liquid ratio of 1:35.34, extraction time of 7.94 h, extraction temperature of 62.85°C. Under the optimized conditions, the predicted tannin extraction yield reaches 58.55%, while the actual extraction yield is 57.42% with the relative error of 1.13%.
