Ijusi yepesika exineneyoImveliso yinkqubo yokuvelisa eqhelekileyo eguqula iipesika ezintsha zibe ziimveliso ezigqityiweyo ezinyibilikayo kakhulu neziqinileyo. Injongo yayo ephambili kukugcina incasa yendalo, umbala kunye nesondlo seepesika ezintsha. Imveliso yokugqibela idla ngokufikelela kwi-65% ~ 70% yezinto eziqinileyo ezinyibilikayo, kwaye isetyenziswa kakhulu ekuxubeni iziselo, kwiimveliso zobisi, ekubhakeni nakwezinye iindawo.
1. Unyango lwangaphambi kwezixhobo eziluhlaza: Ukusuka kwiziqhamo ezitsha ukuya kwi-Pulp ekhuselweyo ngombala
Eli lithuba lokuqala ukuqinisekisa umgangatho osisiseko wemveliso egqityiweyo, nto leyo egqiba ngokuthe ngqo incasa elandelayo kunye nozinzo lombala.
- Ukukhetha nokuCoca iziqhamo: Khetha iipesika ezintsha ezinokuvuthwa okungu-80% ~ 90%, azinazo izinambuzane nezifo, kunye nomlinganiselo ohambelanayo weswekile-asidi, susa iziqhamo ezibolileyo nezineengxaki. Hlamba nge-spray yamanzi acocekileyo; kwiipesika ezine-fuzz eninzi, ukucoca ngebrashi kungasetyenziswa. Ukuba kuyimfuneko, isibulali-ntsholongwane esikumgangatho wokutya singasetyenziselwa ukubulala iintsholongwane kumphezulu, uze uhlambe iintsalela kakuhle.
- Ukugalela kunye nokutyumza: Yahlula imingxunya yeepetshi ngepitter yomatshini, utyumze ipulp ibe yipulp efanayo enobukhulu be-2 ~ 3mm. Amasuntswana amakhulu kakhulu kufuneka aphetshwe ukuthintela imiphumo emibi kwimveliso yejusi elandelayo.
- Unyango lokukhusela umbala: Yongeza i-vitamin C eyi-0.05% ~ 0.1% okanye isixa esifanelekileyo se-citric acid ngexesha lokutyumza ukuze uthintele i-enzymatic browning, uthintele i-peach pulp ukuba ingatshintshi umbala, kwaye uqinisekise ukuba imveliso yokugqibela inombala wegolide oqaqambileyo.
2. Ukuyila nokulungisa: Phucula isivuno sejusi kunye nokuzinza kwemveliso
Eli nqanaba lichaza ukusebenza kakuhle kokukhupha ijusi, ukuhanjiswa kokukhanya kwejusi exineneyo kunye nokukwazi kwayo ukumelana nokuna kwemvula ngexesha lokuphelelwa kwayo.
- Ukutsalwa kweJusi: Sebenzisa i-screw press okanye i-airbag press ukuze ucubungule i-peach pulp, ufumane isivuno sejusi esingaphezulu kwama-70%. Inani elincinci le-enzyme ye-pulp linokongezwa ngaphambi kokutsalwa kwejusi ukunceda ekuboliseni i-pectin kunye nokuphucula ngakumbi ukusebenza kakuhle kokutsalwa kwejusi.
- Ukucoca Okurhabaxa kunye nokususa iintsalela: Hluza ijusi yepetshi ekhutshiweyo ngesikrini sesihluzo se-60 ~ 100 mesh ukususa i-crude fiber kunye neenkunkuma ezinkulu ze-granular pulp, ukuze ufumane ijusi yepetshi ecrude ecacisiweyo ekuqaleni.
- Ukucaciswa kwe-Enzymatic: Yongeza i-pectinase (0.0125% ~ 0.02%) + inani elincinci le-amylase kwijusi yepetshi ekrwada, kwaye wenze i-enzyme hydrolysis kwi-50 ~ 55℃ kangangeyure eyi-1 ~ 3 ukuze ubolise ngokupheleleyo i-pectin ye-macromolecular kwijusi, uphephe ukuqhekeka kunye nokuna kwemvula ngexesha lokugcina okulandelayo.
- Ukuhluzwa Okucokisekileyo Nokucocwa: Sebenzisa inkqubo edibeneyo yokuhluzwa kweplate-and-frame kunye ne-ultrafiltration membrane (ubungakanani be-pore 0.5 ~ 0.8μm) ukuze ubambe ngokupheleleyo ii-colloids ezisele, ii-heteroproteins kunye nezinto eziqinileyo ezixhonyiweyo, ekugqibeleni ufumane ijusi ecacileyo enokuhambisa ukukhanya okuphezulu kunye nozinzo oluqinileyo.
3. Inkqubo yoQokelelo: Ikhonkco loBugcisa eliPhambili
Kukho iinkqubo ezimbini eziphambili ezifumanekayo zokukhetha ngokwendawo ebekwe kuyo imveliso, kunye nomgaqo ophambili wokuphepha ukonakala kobushushu obuphezulu kwizinto ezinencasa ezibuthathaka kubushushu.
- Uxinzelelo oluphantsi lobushushu beVacuum (Inkqubo eQhelekileyo): Yitshise kwaye uyikhuphe emanzini phantsi koxinzelelo oluphantsi kwi-50~60℃ ngeqondo lokucoca eliyi-0.08~0.095MPa, okonyusa izinto ezinyibilikayo zejusi yepesika ukusuka kwi-10%~12% yokuqala ukuya kwi-65%~70%. Le nkqubo inciphisa kakhulu ukutshatyalaliswa kwevumba lepesika ngobushushu obuphezulu kwaye yehlisa iindleko zokugcina nezokuthutha ezilandelayo.
- Uxinzelelo lweMembrane olukwiqondo lobushushu obuqhelekileyo (Inkqubo yeMveliso ephezulu): Sebenzisa i-nanofiltration membrane ukuze uphelelwe ngamanzi emzimbeni kubushushu obuqhelekileyo be-25 ~ 35℃, ngaphandle kotshintsho lwesigaba kuyo yonke inkqubo. Izinga lokugcina izinto ezinencasa kunye neevithamini linokufikelela ngaphezulu kwe-98%, phantse kungabikho "ncasa ephekiweyo", kwaye ukusetyenziswa kwamandla kuphantsi kunelo loxinzelelo lwendabuko lokuphuma komphunga. Ifanelekile ukuvelisa ijusi yepetshi exineneyo enexabiso eliphezulu.
- Ukuphucula Ukubuyiswa Kwevumba: Imizila yemveliso ephezulu idla ngokuxhotyiswa ngesixhobo sokubuyisela umswakama wezinto ezinuka kamnandi, esidibanisa kwaye siqokelele ivumba lepesika eliphumileyo ngexesha lenkqubo yokugxila, size silifake kwijusi egqityiweyo ukuze sibuyisele ivumba lendalo lepesika ezintsha.
4. Ukuxuba kunye nokususa igesi: Yenza ngcono incasa kunye nomgangatho
Emva kokulungisa iswekile kunye ne-asidi kwiixabiso ezijoliswe kuzo ngokwemigangatho yemveliso, yenza i-vacuum decompression degassing ukususa ioksijini enyibilikisiweyo kwijusi, ukunciphisa ukutshintsha kombala we-oxidative kunye nokuwohloka kwencasa ngexesha lokugcina okulandelayo, kwaye uphephe ukuqhuma kwegwebu ngexesha lokuzalisa okuchaphazela isiphumo sokutywina.
5. Ukubulala iintsholongwane kunye nokuzalisa: Qinisekisa ukhuseleko kunye nobomi obude beshelufu
- Unyango lokubulala iintsholongwane: Beka phambili ukubulala iintsholongwane kwiqondo lobushushu eliphezulu kakhulu kwi-UHT, ugcine imizuzwana embalwa kwi-110~120℃, okanye usebenzise i-pasteurization kwi-95℃ imizuzwana engama-30, engenakukwazi ukubulala iintsholongwane ngokupheleleyo kuphela, kodwa ikwanciphisa umonakalo kwincasa kunye nesondlo.
- Ukuzaliswa kwe-Aseptic: Emva kokubulala iintsholongwane, zipholise ngokukhawuleza ukuya kubushushu obuqhelekileyo, galela ijusi exineneyo kwizikhongozeli ezingangenisi ukukhanya nezivaliweyo kwindawo engena-septic. Imveliso egqityiweyo ingagcinwa ixesha elide kubushushu obuphantsi obuyi-0 ~ 5℃ ngomgangatho ozinzileyo kwaye akukho kubohla lula.
