Origin of gelbstoff
Borrowed from German Gelbstoff (literally “yellow substance”) (coined by K. Kalle in a 1966 article: see the quotation), from German gelb (“amber, yellow”) (ultimately from Proto-Indo-European *ǵʰelh₃wós (“yellow”), from *ǵʰelh₃- (“green, yellow”) + *-wós (“suffix forming adjectives from verb stems”)) + German Stoff (“matter, stuff, substance”) (from Proto-West Germanic *stoppōn (“to close; to fill, stop up”), possibly ultimately from Proto-Indo-European *(s)tew- (“to hit; to push”)).
