ABSTRACT:
A nucleic acid-reduced substantially allergen-free single cell protein product is obtained by culturing a yeast, fungi or bacterium on an ultra-low sulfate medium, treating the produced cells with a base at a pH of about 9.5 with moderate heat, thereafter treating the base-treated cells with acid to a pH of about 4 with moderate heat, and treating the base-treated acid-treated cells with a relatively high temperature short time heat shock, followed by extrusion. Optionally, the extruded product is annealed.
