Chepfu yayo inonyungudika muchiropa painopinda mumuviri. Kune mishumo yepasi rose yechepfu yakatorwa kubva pakushandiswa kwesodium benzoate semushonga unochengetedzaKunyangwe pasina kunzwisisana kwakabatana, mune dzimwe nyika nenzvimbo zvakarambidzwa, zvakaita seUnited States, Japan, uye Hong Kong, chikafu chemumagaba chakarambidzwa nacho. Potassium sorbate, iyo isina chepfu yakawanda, inoshandiswa zvakanyanya.
