Pasteurization ubisi ekhaya

iimveliso zobuchwepheshe Pasteurization ogama wokuwonga elaa eziphilayo French Lui Pastera, owayephila kwinkulungwane yeshumi elinesithoba emva kwexesha. kubume bayo siyifumana iimveliso omnye ukuvumelana kufudumeze ulwelo, nto leyo ekhokelela yokubulala evela iintsholongwane ezahlukeneyo. Kuyenzeka ukwandisa lokugcinwa kwezinto iimveliso. ekuqaleni nobuchwepheshe ezenzelwe ibhiya newayini.

Ukusetyenziswa kwezi le ndlela kulondolozo yaba ekwenzeni imveliso zobisi. Pasteurisation yobisi - inkqubo ukufudumeza ukuya lobushushu kufutshane ukubilisa, nokutshatyalaliswa ezincinane yayintsholongwane eyosulela ngaphandle kokutshintsha iimpawu ezingundoqo - ivumba, ukuguda noburhabaxa kwakunye nencasa.

Eyona njongo ye pasteurization yobisi - ukuthintela Ukuba muncu yayo ngaphambi kwexesha, obe ubaqhiphukisa iibhaktheriya asidi lactic, nokukotshwa Escherichia coli kunye namanye amagciwane.

Xa imveliso industrial lokulawula pasteurization ngempumelelo isebenzisa yokusabela ukuya phosphatase. Xa ngovukelo Kukholelwa ukuba bonke asporogenous iintsholongwane yayintsholongwane eyosulela ukuba abulawe. Inkqubo Ukusebenza liphezulu kuphela xa ubisi ngoko nangoko emva ukusenga sele lupholile ukuya kwiqondo elithile yaye zigcinwe de kube pasteurization. Ngokuba lo Ukupholisa ezizodwa amatanki zisetyenziswa kwiifama imfuyo.

Nto ithetha ukuba, pasteurization ubisi enokwenziwa ngeendlela ezintathu ezahlukeneyo.

pasteurisation Continuous - ubisi lashushu lobushushu degrees 65 igcinwe kule meko kangangeyure.

Elifutshane-pasteurization - ukufudumeza kwenzeka degrees 75 kwaye processing buphelisiwe emva kwemizuzwana mabini.

Instant ubisi pasteurization - a amalahle ukuya kwiqondo lobushushu degrees 85 - yaye ngoko nangoko ostuzhennoy. Ukuba pasteurization amasi wenziwa nangoko etshintsha iimpawu zomzimba lwemichiza kwezinye izinto, ngaloo ndlela itshintsha incasa yawo.

Izixhobo kuba nemveliso yobisi isetyenziswa kuphela kumgangatho mveliso. Ekhaya, iimeko pasteurization enokwenziwa usebenzisa kwibhoyila kabini. Kuqala ke kufuneka abilayo isikhongozeli apho ubisi, zahambisa iya kugcinwa enqatheni oveni eqhelekileyo izidanga malunga nekhulu imizuzu malunga namashumi amabini. Okanye ungakwenza oko iindlela eziqhelekileyo ngokusebenzisa umphunga.

Ngaphezu koko, egumbini eliphezulu izele umkhumbi ubisi kunye ubushushu ibekwe ngendlela yokuba ungabinako bachukumise iindonga umzantsi - amanzi. Ubisi kwaziswa lobushushu degrees 65, baxhaya rhoqo imizuzu engamashumi amathathu. Kubalulekile ukuqinisekisa ukuba amaqondo obushushu akazange avuke.

Ukuba ubisi ndinobushushu degrees 75, ukuba pasteurization kufuneka wenziwe kuphela imizuzu elishumi elinesihlanu. Emva ukuba itanki ubisi kufuneka ukuba emanzini umkhenkce, nangoku ukukhwezela, de ubushushu kusithwa degrees Celsius ezine.

Emva koko, ubisi igalelwe isikhongozeli zintsholongwane, isiciko baze bafakwe kwisiqandisi. Njengoko awukwazi ukuphila iiveki ezimbini ukuba bayaxabana.
