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 sifakwe i-gelatin kule 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-casin, i-casin 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 sinokunikezelwa ngokweemfuno ezahlukeneyo zomgangatho weyogathi.
