ABSTRACT:
A method of producing a chromium yeast product having a high intracellular chromium content which is useful as a dietary chromium supplement is provided by treating an aqueous suspension of live yeast cells adjusted to an acidic pH in the range of 4 to about 7 with a water-soluble non-toxic chromium salt under essentially non-growth conditions for a period sufficient to permit the absorption of a significant amount of intracellular chromium ion by said yeast cells. The yeast cells so treated may be concentrated, washed free of extracellular chromium salts and dried or further grown by the addition of nutrients to the media, said growth period being of sufficient duration to reduce the intracellular chromium content of the yeast to a predetermined level followed by recovery, washing and drying of the chromium yeast as aforesaid.
