Energy requirements were monitored during the production of a beet colorant on a pilot plant scale. Colorant production involved centrifugation, concentration by fermentation, vaccum concentration, and spray drying. The economic feasibility of adding the fermentation operation to the present extraction and concentration operations was studied. Data were obtained on the production rate, pigment recovery, energy consumption (electrical, steam, gas), and pigment concentration at each unit operation. Calculations were based on a ton of raw beets processed. Energy costs were $15.57 per ton. The final spray dried colorant contained between 3 and 5% pigment depending on raw product quality. Byproducts of yeast and alcohol helped to offset 16% of the energy and raw product costs.
