Khoros Nishan gum factory belonged to a Jewish capitalist named Mirza Agha Mahboobi (after leaving, probably: Yusuf Mehbobian). The production of cock chewing gum started in 1335. But Khoros was not the first producer of chewing gum. Rather, before that, there were “Parrot” chewing gum and “Peacock” chewing gum in Iran, but after the presence of cock chewing gum, they lost their position and said goodbye to the market.
