Drying Apricot Optimization's Experimental Design

The drying apricot process study through an experiment factorial design allows us to reduce alteration of final product. The targeted variables are sodium metabisulfite concentration (g/l), dipping time (min) and drying temperature (�C). A complete factorial design (23) was made in order to determine the factors and their interactions which have a statistically significant influence on the studied response. Hight values sodium metabisulfite concentration, dipping time and drying temperature have a negative effect on alteration reduction. Optimal factor production is 80 g/l of sodium metabisulfite, 45 min of dipping time and 72�C of drying temperature. The later has great impact on the quality of final product.
