Pasteurization mukaka kumba

Pasteurization michina zvigadzirwa ainzi chokuremekedza microbiologist French Lui Pastera, vaigara mukupera namapfumbamwe remakore. Chaizvoizvo Its uvete chete kudziyisa mvura kusachinja-chinja zvinhu, iyo inotungamirira decontamination kubva tusingaoneki siyana. Zvinokwanisika kuwedzera pasherefu muupenyu zvigadzirwa. pakutanga Michina yakagadzirirwa doro uye waini.

Kushandiswa kwakapararira nzira iyi kuchengetedza yaiva kubudiswa dheri zvigadzirwa. Pasteurisation mukaka - munhu kudziyisa mutoo kuti tembiricha pedyo kubika, uye kuparadzwa pathogenic tusingaoneki pasina kuchinja dzinokosha ehupfumi - kunhuwidza, unaku uye kuravira.

Chinangwa chikuru chemusha pasteurization mukaka - kudzivirira ayo vakurumidze acidification, izvo kuti lactic inouraya utachiona, uye kubereka vana Escherichia coli coli uye mamwe majemusi.

In maindasitiri kugadzira nokuda kudzorwa pasteurization zvinobudirira anoshandisa sei munhu phosphatase. Kana backlash Zvinodavirwa kuti zvose asporogenous utachiona pathogenic vari kuurayiwa. Masero kunyatsoshanda kumusoro chete kana mukaka pakarepo pashure kukama kwave dzaserera kune imwe tembiricha uye akaramba ari kusvikira pasteurization. Nokuti kutonhora chinokosha ichi Matangi anoshandiswa pamusoro zvipfuwo mumapurazi.

In tsika, iyo pasteurization mukaka kunogona kuitwa nhatu dzakasiyana.

Kuramba pasteurisation - mukaka neshungu kuti tembiricha 65 madhigirii uye inotarisirwa ari mamiriro ichi kweawa.

Short-pasteurization - kudziyisa kunoitika 75 madhigirii uye kubudiswa iri wakagumiswa pashure masekonzi makumi maviri.

Pakarepo mukaka pasteurization - a muchidziisa mumwe tembiricha rworwendo 85 - uye pakarepo ostuzhennoy. Kana pasteurization mukaka chakaitwa pakarepo anoshandura mumuviri uye zvemakemikari zvivako zvimwe zvinhu, nokudaro kuchinja chainaka.

Equipment nokuti kugadzirwa mukaka chete kushandiswa pamusoro muindasitiri akamboona. Pamba, pasteurization mamiriro anogona kuitwa uchishandisa bhaira kaviri. Tinofanira kutanga chenesa mugaba umo mukaka, ukaisa hunowanikwa muna zvake muovheni pa madhigirii anenge zana kwemaminitsi anenge makumi maviri. Kana unogona kuzviita kuburikidza kwakajairika nzira vachishandisa chiutsi.

Uyezve, yepamusoro yakazara mukaka steamer uye lämpömittari anoiswa nenzira kuti hazvina kubata madziro uye nechepasi - mvura. The mukaka angasvikira munhu tembiricha 65 inegumi, uye kumutsa nguva dzose kwemaminitsi makumi matatu. Zvakakosha kuti tive nechokwadi kuti tembiricha haana kumuka.

Kana mukaka nenharo 75 madhigirii, kuti pasteurization yaifanira chete kwemaminitsi gumi nemashanu. Pashure paizvozvo mukaka tangi kunodiwa Kunyudzwa chando mvura, vachiri vakamutsa, kusvikira tembiricha anodonhedza mana Celsius.

Zvadaro, mukaka yakadururirwa munhu sterilized mudziyo, muvharo uye akaisa firiji. Sezvo haugoni kurarama mavhiki maviri kuti vadzoke yakashapa.
