Izixhobo ezincinci zeYogathi

Inkcazelo emfutshane:

Iyogathi luhlobo lwesiselo sobisi esinencasa eswiti nemuncu.Luhlobo lwemveliso yobisi oluthatha ubisi njengento ekrwada, lufakwe kwi-pasteurized luze ludityaniswe nebhaktiriya eluncedo (isiqalo) ebisini.


Iinkcukacha zeMveliso

Iithegi zeMveliso


Iimveliso zeyogathi kwimarike ubukhulu becala zezodidi oluqiniswayo, uhlobo olushukumisayo kunye nohlobo lwencasa yeziqhamo ezineentlobo ngeentlobo zejam yejusi yeziqhamo.

Inkqubo yokuveliswa kweyogathi inokushwankathelwa njengezithako, ukufudumeza, i-homogenization, inzala, ukupholisa, ukugoba, (ukuzalisa: i-yoghurt eqinisiweyo), ukuvutshelwa, ukupholisa, (ukuxuba: i-yoghurt evuselelweyo), ukupakishwa kunye nokuvuthwa.Isitashi esilungisiweyo songezwa kwinqanaba lokudibanisa, kwaye umphumo wayo wesicelo uhambelana ngokusondeleyo nolawulo lwenkqubo

Izithako: ngokwe-balance balance sheet, khetha izinto eziyimfuneko, ezifana nobisi olutsha, iswekile kunye ne-stabilizer.Isitashi esilungisiweyo sinokudibaniswa ngokwahlukileyo kwinkqubo yezithako, kwaye singongezwa emva kokuxuba okomileyo kunye nezinye iintsini zokutya.Ukuthathela ingqalelo ukuba isitashi kunye netshungama yokutya zizinto ezininzi zemolekyuli ezine-hydrophilicity eyomeleleyo, kungcono ukuzixuba kunye nesixa esifanelekileyo seswekile egayiweyo kwaye zinyibilike kubisi olushushu (55 ℃ ~ 65 ℃) phantsi kwesantya esiphezulu sokuvuselela ukuphucula ukusasazeka kwabo. .

Enye inkqubo yokuhamba kwesixhobo seyogathi:
Ukushisa kwangaphambili: injongo yokufudumala kukuphucula ukusebenza kakuhle kwenkqubo elandelayo ye-homogenization, kwaye ukukhethwa kokushisa kwangaphambi kokushisa akufanele kube ngaphezu kokushisa kwe-gelatinization yesitashi (ukuphepha isakhiwo se-particle sonakaliswe kwinkqubo ye-homogenization emva kwe-starch gelatinization).

I-Homogenization: i-homogenization ibhekiselele kunyango lomatshini lwe-globules yamafutha obisi, ukwenzela ukuba i-globules yamanqatha amancinci ahlakazwe ngokulinganayo kubisi.Kwinqanaba le-homogenization, izinto eziphathekayo ziphantsi kwe-shear, i-collision kunye ne-cavitation forces.Isitashi sesitashi esilungisiweyo sinokuxhathisa okuqinileyo kwe-chear ngenxa yokuguqulwa kwe-cross-linking, enokugcina ingqibelelo yesakhiwo segranule, esinceda ukugcina i-viscosity kunye nokumila komzimba we-yogurt.

Ukubulala inzala: utyando lusetyenziswa ngokubanzi, kwaye inkqubo yokuvala inzala ye-95 ℃ kunye ne-300s yamkelwa ngokubanzi kwizityalo zobisi.Isitashi esilungisiweyo sandiswa ngokupheleleyo kwaye i-gelatinized kweli nqanaba ukwenza i-viscosity.

Ukupholisa, i-inoculation kunye ne-fermentation: isitashi se-denatured luhlobo lwe-molecular substance, egcina ezinye iimpawu zesitashi sokuqala, oko kukuthi, i-polysaccharide.Ngaphantsi kwexabiso le-pH ye-yogurt, isitashi asiyi kuthotywa yibhaktheriya, ngoko inokugcina ukuzinza kwenkqubo.Xa ixabiso le-pH lenkqubo ye-fermentation lehla kwindawo ye-isoelectric ye-casein, i-casein i-denaturates kwaye iqina, yenza inkqubo yenethiwekhi ye-dimensional emithathu edityaniswe namanzi, kwaye isakhelo siba curd.Ngeli xesha, isitashi se-gelatinized singazalisa i-skeleton, sibophe amanzi akhululekile kwaye sigcine ukuzinza kwenkqubo.

Ukupholisa, ukuvuselela kunye nasemva kokuvuthwa: injongo yokuvuselela ukupholisa kweyogathi kukuthintela ngokukhawuleza ukukhula kwe-microorganisms kunye nomsebenzi we-enzyme, ngokukodwa ukukhusela ukuveliswa kwe-asidi ngokugqithiseleyo kunye nokuphelelwa amandla kwamanzi ngexesha lokuvuselela.Ngenxa yemithombo eyahlukeneyo yemathiriyeli ekrwada, isitashi esilungisiweyo sinedigri ye-denaturation eyahlukileyo, kwaye isiphumo sesitatshi esilungisiweyo esahlukileyo esisetyenziswa kwimveliso yeyogathi ayifani.Ke ngoko, isitashi esilungisiweyo sinokubonelelwa ngokweemfuno ezahlukeneyo zomgangatho weyogathi.
