(a) In an analysis, sugar beet is found to contain 75% of water and 17.5% of sugar. If of the remaining material, 25% is soluble and 75% insoluble, calculate the sugar content of the expressible juice assumed to contain water and all soluble solids pro rata. (b) The beets are extracted by addition of a weight of water equal to their own weight and after a suitable period the soluble constituents are concentrated evenly throughout all the water present. Calculate the percentage of the total sugar left in the drained beet and the percentage of the total sugar extracted, assuming that the beet cells (insoluble) after the extraction have the same quantity of water associated with them as they did in the original beet. (c) Lay out a materials balance for the extraction process
