Ho ekelletsa moo, kamoreng e ka holimo e tletse lebese steamer le selekanyamogote e kenngoa ka tsela eo ka eona ha ho ame ho marako le tlase - metsi. lebese e tlisoa ka mocheso oa likhato tse 65, 'me hlohlelletsa kamehla bakeng sa metsotso e mashome a mararo. Ho bohlokwa ho etsa bonnete ba hore mocheso ha baa ka ba tsoha.

Haeba lebese ke halefile ho likhato tse 75, e le hore pasteurization lokela ho phethahatsoa feela ka metsotso e leshome le metso e mehlano.
