Nisinchikafu chechikafu chekuchengetedza chikafu chakawana mukurumbira mumakore achangopfuura nekuda kwekugona kwayo kuwedzera hupenyu hwesherufu yekudya.Nisin, inotorwa kubva kuLactococcus lactis, inowanzo shandiswa chikafu chinowedzera chinogona kuvharisa kukura kwebhakitiriya, kunyanya ayo anokonzera kukanganisa kwekudya.

Yakarongedzerwa sepolypeptide, nisin inowanzoitika mumhando dzakasiyana dzezvikafu zvakaviriswa uye yakashandiswa kuchengetedza chikafu kwemazana emakore.Inoshanda nekunangisa masero madziro ebhakitiriya, zvichiita kuti aputse uye kudzivirira kukura kwavo.Iyi nzira yechisikigo yekuita inosiyanisa nisin kubva kune mamwe makemikari anochengetedza, ayo anowanzo kuunza njodzi dzinogona kuitika pahutano.

Chikafu-giredhi nisin yakabvumidzwa nemasangano anodzora akadai seChikafu neDrug Administration (FDA) neEuropean Food Safety Authority (EFSA) sechivharo chekudya kwakasiyana siyana.Izvi zvinosanganisira nyama yakagayiwa, zvigadzirwa zvemukaka, zvekudya zvemumagaba, uye kunyange zvinwiwa.Nekuda kwemabviro ayo echisikigo uye chengetedzo chimiro, nisin inoonekwa zvakanyanya seyakachengeteka uye inoshanda kuchengetedza sarudzo.

Imwe yemabhenefiti makuru e nisin sechikafu chekuchengetedza chikafu ndeye wide-spectrum antimicrobial chiitiko.Yakaratidzwa kuva inoshanda kurwisa mabhakitiriya akasiyana-siyana, kusanganisira mamwe ehutachiona hwekudya.Nekutadzisa kukura kweutachiona uhwu, nisin inobatsira kudzivirira kusvibiswa kwechikafu uye inoderedza njodzi yechirwere chekudya.

Mukuwedzera, nisin inoramba yakagadzikana kunyange pasi pekushisa kwakanyanya uye acidic mamiriro, zvichiita kuti ive yakakodzera kune dzakasiyana-siyana dzekugadzira chikafu.Kudzivirira kwayo kupisa kunovimbisa kuti inochengetedza zvimiro zvayo zvekuchengetedza kunyangwe mushure mekubika kana pasteurization, kuwedzera hupenyu hwesherufu pasina kukanganisa kuravira kana kunaka.

Imwe bhenefiti yakakosha yenisin sechikafu chekuchengetedza ndechekuti ine zvishoma mhedzisiro pane yekunzwa kwechikafu.Kusiyana nemamwe makemikari anochengetedza anogona kuchinja kuravira kana kuumbwa kwechikafu, nisin yakawanikwa isina chinhu chakakosha pahunhu hwekunzwa.Izvi zvinoreva kuti zvikafu zvakachengetwa ne nisin zvinogona kuchengetedza kunhuhwirira kwavo kwepakutanga uye magadzirirwo, zvichipa vatengi ruzivo rwemhando yepamusoro.

Nisin inowanzo kuwanikwa muhupfu uye inogona kuiswa nyore nyore mukugadzira chikafu.Vagadziri vechikafu vanogona kuwedzera zvakati wandei zve nisin poda kune yavo magadzirirwo kuti vawane inodiwa kuchengetedza maitiro.Mukuwedzera, nisin poda ine kugadzikana kwepamusoro uye hupenyu hurefu hwesherufu, zvichiita kuti ive sarudzo inodhura yekuchengetedza chikafu.

Mukupedzisa, nisin zvechokwadi inochengetedza chikafu chepanyama chine mabhenefiti akawanda.Iyo antimicrobial properties, yakafara-spectrum basa, kupisa kwekudzivirira uye kushoma kukanganiswa kwezvinhu zvekunzwa kunoita kuti ive chishandiso chakakosha kune vanogadzira chikafu.Nemvumo yayo yemutemo uye kuchengetedzeka kwakaratidza, nisin inoramba ichiita basa rakakosha mukuwedzera hupenyu hwesherufu yezvakasiyana zvigadzirwa zvechikafu uku uchisimbisa mhando uye chengetedzo yevatengi.
