Soda additive "no longer considered safe," gets long-awaited FDA ban
By the early 1960s, the FDA had put BVO on its first inventory of food additives it deemed generally safe-designated “Generally recognized as safe” or GRAS. But safety concerns quickly surfaced, and by the late 1960s, the FDA had already limited its use to a flavoring stabilizer and capped the amount that could be used to 15 parts per million. The FDA reports that only a few beverages in the US still use the additive. Consumer advocates chided the FDA while celebrating the ban.
