Pasteurization ubisi ekhaya

imikhiqizo pasteurization ubuchwepheshe okuthiwa yokudumisa samagciwane French Lui Pastera, owaphila ngasekupheleni kwekhulu nesishiyagalolunye. essence yayo itholakala olulodwa Ukushisa uketshezi imikhiqizo ukungaguquguquki, okuholela decontamination kusuka nezilwanyana ezincane ezihlukahlukene. Kungenzeka ukwandisa ukuphila eshalofini of imikhiqizo. ekuqaleni ubuchwepheshe eyenzelwe ubhiya newayini.

Ukusetshenziswa kabanzi le ndlela ukulondolozwa ubekade ukucutshungulwa imikhiqizo yobisi. Pasteurisation ubisi - inqubo Ukushisa a close lokushisa ukuze abilayo, futhi ukubhujiswa nezilwanyana ezincane pathogenic ngaphandle kokushintsha izakhiwo eziyisisekelo - iphunga, ukuthungwa kanye ukunambitheka.

Injongo eyinhloko yawo pasteurization ubisi - ekuvimbeleni acidification yayo ngaphambi kwesikhathi, okuyinto abangela acidosis acid amagciwane, nokukhiqizwa Escherichia coli namanye amagciwane.

Ngo ukukhiqizwa yezimboni sokuphatha pasteurization ngempumelelo isebenzisa asabela ngayo lapho umuntu phosphatase. Lapho backlash Kukholakala ukuthi bonke asporogenous namagciwane abangela izifo kuthiwa babulawe. Inqubo kahle kuphezulu kuphela uma ubisi ngokushesha ngemva zizosengwa iye selehlile lokushisa ethile futhi eyigcina kulo kuze pasteurization. Ngenxa yalesi Ukupholisa ekhethekile amathangi ezisetshenziswa imfuyo amapulazi.

Ngo practice, pasteurization ubisi kungaba kwenziwe ngezindlela ezintathu ezahlukene.

Okuqhubekayo pasteurisation - ubisi ukufuthelana lokushisa 65 degrees futhi zigcinwe ngaphakathi lo sho ihora.

Esifushane pasteurization - Ukushisa kwenzeka ku-degrees 75 nasekufuyeni inqanyulwa emva kwemizuzwana amabili.

Instant ubisi pasteurization - a amalahle lokushisa 85 degrees - futhi ngokushesha ostuzhennoy. Uma pasteurization ubisi senziwa kweso sishintsha Izakhiwo namakhemikhali ezinye izakhi, ngaleyo ndlela ekushintsheni ukunambitheka kwako.

Izinsiza kusebenza for ekukhiqizeni ubisi isetshenziswa kuphela ngezinga ezimbonini. Ekhaya, izimo pasteurization kungaba kwenziwe usebenzisa kubhayela double. Okokuqala sidinga abilayo isitsha lapho ubisi, ngokufakwa izogcinwa ke kuhhavini elivamile degrees yikhulu imizuzu cishe abangamashumi amabili. Noma ongakwenza ngokulandela izindlela ezivamile usebenzisa umusi ke.

Ngaphezu kwalokho, ekamelweni eliphezulu ligcwele ubisi ngesitimu futhi izinga lokushisa ibekwe ngendlela yokuthi awusebenzi uthinte izindonga phansi - amanzi. Ubisi kulethwa lokushisa 65 degrees, ugovuze njalo imizuzu amathathu. Kubalulekile ukuqinisekisa ukuthi izinga lokushisa zingavuki.

Uma ubisi eliwu degrees 75, ukuthi pasteurization kufanele sigcwaliswe kuphela imizuzu eyishumi nanhlanu. Ngemva kwalokho ngethangi lobisi uma kudingeka ukuba kukhishwe emanzini iqhwa, namanje sibhebhezela, kuze izinga lokushisa lehla ezine degrees Celsius.

Ngemva kwalokho, ubisi is batheleka a inzalo esitsheni, isivalo bese ifakwa esiqandisini. Njengoba ungeke ukwazi ukusinda amasonto amabili ukuthi uvule omuncu.
