Abstract

The study was conducted in order to optimize the process for dried mangoes using response surface methodology (RSM). Preliminary sensory studies were done to determine the quality and preference of consumers for commercially-available dried mangoes. The sensory results were used as reference for the optimization of dried mangoes. The existing methods for dried mango processing were also studied. In the optimization for processing of the dried mangoes, independent variables such as peel color index (PCI 3, PCI 4 and PCI 5), soaking method (dry and wet) and drying temperature (40oC, 50oC, 60oC) were considered. All the samples were subjected to physicochemical analysis for moisture content, total color difference, texture, residual sulfite and vitamin C content. The independent variables and the response factors were then correlated in RSM. Sensory tests of the dried mangoes for the dry and wet methods and a simple cost analysis were also done. All the variables introduced affected the response factors selected. In performing numerical optimization, the optimum combination of the process variables is PCI5-Dry-46.60oC. For graphical optimization, the formulations that produced the optimum responses were PCI5-Dry-40oC and PCI3- Wet-40oC. These two fomulations obtained high acceptability for both quality scoring and hedonic test. The simple cost analysis done showed that the more cost effective formulation is PCI5-Dry-40oC.
