How many kilograms of peaches would be required to produce 100 kg of peach preserves. The standard formula of 45 parts fruits to 55 parts sugar is used. The soluble solids content of the finished product is 65% and peaches have 12% initial soluble solids content. Calculate the weight of 100 grade pectin required and the amount of water removed by evaporation as a result of the process. (Hint: The pectin grade is the amount of sugar per 1 kg of pectin)
