| Abstract | In this study density sorting of potatoes was studied using a specifically designed and fabricated mechanical separator for improving the chip quality. The experimental potato separator operated on floatation principle using sodium chloride brine solutions of varying densities. it was shown that potatoes could be separated effectively into high and low density groups with acceptable levels of overlapping. The specific gravity of brine close to that of tubers was determined to be the best for optimum performance. Total solids (dry matter) in potatoes (Spunta variety) and yield of chips were directly related with the density of potatoes. The density of potatoes affected the bulk density, oil content, moisture content, crispness of fried chips. High density potatoes resulted in the increased bulk density, decreased fat absorption and moisture content and more crispness of the chips. In addition, the results based on subjective and objective quality evaluations were in direct agreement. Potato chips of high acceptable quality can be produced on the basis of a simple and relatively inexpensive separation process for sorting the high density tubers. |
