Pasteurization kana pasteurization inzira inouraya hutachiona (kunyanya mabhakitiriya) muchikafu nechinwiwa, semukaka, muto, chikafu chemumagaba, bhegi mubhokisi rekuzadza muchina uye bhegi mubhokisi rekuzadza muchina uye nevamwe.
Yakagadzirwa nemusayendisiti wechiFrench Louis Pasteur muzana remakore rechigumi nemapfumbamwe. Muna 1864 Pasteur akawana kuti kudziyisa doro newaini zvakanga zvakakwana kuuraya mabhakitiriya akawanda aikonzera kuparara, zvichiita kuti zvinwiwa izvi zvisavava. Maitiro anozadzisa izvi nekubvisa pathogenic microbes uye kudzikisa huwandu hwehutachiona kuti hurebe kunaka kwechinwiwa. Nhasi, pasteurization inoshandiswa zvakanyanya muindasitiri yemukaka uye mamwe maindasitiri ekugadzira chikafu kuti uwane kuchengetedza kwekudya uye kuchengetedza chikafu.
Kusiyana nesterilization, pasteurization haina kuitirwa kuuraya tupukanana twese muchikafu. Pane kudaro, ine chinangwa chekudzikisa huwandu hwehutachiona hwehutachiona kuitira kuti dzisakonzerese chirwere (tichifunga kuti pasteurized chigadzirwa chinochengetwa sezvakaratidzwa uye chinopedzwa zuva risati rapera). Commercial-scale sterilization yechikafu haina kujairika nekuti inokanganisa kuravira uye kunaka kwechigadzirwa. Zvimwe zvikafu, senge zvigadzirwa zvemukaka, pulp yemuchero inogona kunge yakanyanya kupisa kuti ive nechokwadi chekuti pathogenic microbes inoparadzwa.
