Cost estimates are based on data provided by A. K. Robins and Co. for still retorts; by F. K. Lawler ["The French BuildEfficient Canneries," Food Engineering, vol. 32, no. 3 (March 1960), p. 64) for hydrostatic cookers; and by the editors ofFood Engineering ["Aseptic Milk Makes N. American Debut," vol. 47, no. 9 (September 1975), p. 15] for aseptic sterilizingequipment. As in the other comparative tables, figures are updated by using the 1977 "M & S Equipment Cost Index."
