QB/T 8179-2026Determination of trivalent chromium and hexavalent chromium in chromium-rich yeasts (English PDF)

QB/T 8179-2026 is the English-translated version of 富铬酵母中三价铬和六价铬的测定.

QB/T 8179-2026 concerns the determination of trivalent chromium and hexavalent chromium in chromium-rich yeast. Chromium-rich yeast is a yeast product enriched with chromium, and the document deals with finding out how much of the metal is present in each of its two forms. It is a method standard, which means that its subject is the analytical procedure rather than the product itself. It addresses only the two chromium forms named in its title and the yeast material in which they are measured.

Producers of chromium-rich yeast, food and supplement manufacturers, testing and analytical laboratories, regulators and buyers who need to verify the chromium content of the product would use it. It is a voluntary standard, as the /T in the code shows. The Ministry of Industry and Information Technology issued it on 13 February 2026, and it takes effect on 1 September 2026. It is a new document and does not replace an earlier edition.
