Detection of Urethane in Non-alcoholic Fermented Food [PDF]

E3S Web of Conferences, 2020
Among fermented foods, urethane often appears, which is a “2A” grade carcinogen. There are many types of fermented foods in my country, and the detection methods are not uniform enough, and no specific urethane detection standards have been formed.
