Abstract
Abstract THE NUCLEIC ACID CONTENT OF SINGLE-CELL PROTEIN (SCP) MATERIALS IS REDUCED TO A LEVEL ACCEPTABLE IN FOOD PRODUCTS BY TREATMENT OF THE WHOLE CELLS WITH AQUEOUS ETHANOLIC MINERAL ACID AT ELEVATED TEMPERATURES WITHIN THE RANGE FROM 60* TO 125* C. REMOVAL OF NUCLEI ACIDS WITHOUT SUBSTANTIAL REMOVAL OF PROTEIN MATERIAL IS ACCOMPLISHED BY LIMITING THE TREATING TIME TO ABOUT 5 TO 30 MINUTES.
