Ijusi yeziqhamo eneziqhamo njengemathiriyeli ekrwada ngokusebenzisa iindlela zomzimba ezifana nokucofa, ukugxilwa kwecentrifugation, ukutsalwa kunye nezinye iimveliso zejusi, zigaywe zibe ziziselo ezenziwe ngeemveliso.Ijusi yeziqhamo igcina uninzi lwezondlo kwiziqhamo, ezinje ngevithamini, iiminerali, iswekile, kunye nepectin kwifiber yokutya.
Ixesha lokugcinwa kwejusi yeziqhamo lifutshane kakhulu, ubukhulu becala ngenxa yempembelelo ye-microorganisms, ngenxa yokuba umsebenzi we-metabolic we-microorganisms kwijusi yeziqhamo usebenza kakhulu, ngoko kubaluleke kakhulu ukukhetha iteknoloji efanelekileyo yokuvala inzala ukuthintela ukuwohloka kweziselo zejusi yeziqhamo. .Ngokubhekiselele ekubulaweni kweziselo zejusi, kuyafuneka ukuba kubulawe iintsholongwane ze-pathogenic kunye neebhaktheriya eziphazamisayo kwijusi, ulawulo lwenani elipheleleyo lamakholoni lihlangabezana nemigangatho yelizwe, kunye nokutshatyalaliswa kwee-enzymes kwijusi ukuze kubekho ukugcinwa okuthile. ixesha kwindawo ethile;enye kukukhusela ukwakheka kwesondlo kunye nencasa yejusi kangangoko kunokwenzeka kwinkqubo yokuvala inzala.
Kwindlela yokuvala inzala kwijusi yeziqhamo, kukho i-pasteurization (iqondo eliphantsi lobushushu bexesha elide indlela yokuvala inzala), ubushushu obuphezulu bexesha elifutshane indlela yokuvala inzala kunye nendlela yokuvala inzala ngokobushushu obuphezulu kakhulu.Ubushushu obuphezulu bexesha elifutshane isiphumo sokuvala inzala ye-thermal ingcono, kodwa ubushushu buhlala buzisa iziphumo ezibi kumgangatho wejusi yeziqhamo, njengokutshintsha kombala, incasa, ilahleko yesondlo, njl.
Kwaye iteknoloji ye-pasteurization, ngokuguqula iprotheni kunye nesakhiwo se-enzyme yeeseli ze-microbial, ngaloo ndlela inqanda umsebenzi we-enzymes, ibulala inani elikhulu leebhaktheriya ezitshabalalisayo kunye neebhaktheriya ze-pathogenic kwijusi yeziqhamo, ngelixa ixabiso lokutya kunye nesondlo sokutya aliyi kuchaphazeleka.Ayinako nje ukufezekisa injongo yokuvala inzala kunye ne-passivation ye-enzymes kwiqondo eliphantsi lobushushu, kodwa inokunceda ukugcina umbala wejusi yeziqhamo, ivumba, incasa, isondlo kunye nokutsha, ukuhlangabezana neemfuno zabathengi abakhuthaza ukutya "kwendalo kunye nempilo".Ke ngoko, ukufunda itekhnoloji ye-pasteurization kubaluleke kakhulu kukhuseleko, umbala kunye nesondlo sejusi yeziqhamo ezitsha.
Kuyafaneleka ukuba uqaphele ukuba i-pasteurization ifakwe kwitoti okanye i-juice yebhotile, ukuba i-juice yebhotile yeglasi, kufuneka ithathelwe ingqalelo ingxaki yokufudumeza kunye ne-precooling, ukuthintela ukuhluka kweqondo lokushisa kukhulu kakhulu kwaye kukhokelela ekuqhumeni kwebhotile, ngoko umatshini wethu we-pasteurization uhlukaniswe amacandelo amane, angala, ukufudumeza kwangaphambili, ukuvala inzala, ukupholisa kwangaphambili kunye nokupholisa, kodwa igama lilonke ngumatshini wejusi yokucoca.
