Ijusi le-peach eligxilileUkukhiqizwa kuyinqubo yokukhiqiza ejwayelekile eguqula amapentshisi amasha abe imikhiqizo eqediwe encibilika kakhulu. Umgomo wayo oyinhloko ukugcina ukunambitheka kwemvelo, umbala kanye nokudla okunomsoco kwamapentshisi amasha. Umkhiqizo wokugcina uvame ukufinyelela ku-65% ~ 70% wezinto ezincibilika kakhulu, futhi usetshenziswa kabanzi ekuxubeni iziphuzo, imikhiqizo yobisi, ukubhaka kanye neminye imikhakha.
1. Ukwelashwa Kwangaphambi Kwezinto Ezingavuthiwe: Kusukela Ezithelweni Ezintsha Kuya Emathunjini Avikelwe Umbala
Lesi yisiqalo sokuqinisekisa ikhwalithi eyisisekelo yomkhiqizo oqediwe, okunquma ngqo ukunambitheka okulandelayo kanye nokuqina kombala.
- Ukukhetha Nokuhlanza Izithelo: Khetha amapentshisi amasha anokuvuthwa okungu-80% ~ 90%, angenazo izinambuzane nezifo, kanye nesilinganiso esivumelanayo sikashukela-asidi, susa izithelo ezibolile nezinephutha. Hlanza ngesifutho samanzi ahlanzekile; kumapentshisi ane-fuzz eningi, ukuhlanza ibhulashi kungasetshenziswa. Uma kudingeka, isibulali-magciwane sokudla singasetshenziswa ekuhlanzeni ubuso, bese uhlanza izinsalela kahle.
- Ukugoba Nokuchoboza: Hlukanisa imigodi yamapentshisi nge-pitter yomshini, cindezela i-pulp ibe yi-pulp efanayo enobukhulu bezinhlayiya obungu-2 ~ 3mm. Izinhlayiya ezinkulu kakhulu kufanele zigwenywe ukuze kuvinjelwe imiphumela emibi ekuvuneni okulandelayo kwejusi.
- Ukwelashwa Kokuvikela Umbala: Engeza i-vitamin C engu-0.05% ~ 0.1% noma inani elifanele le-citric acid ngesikhathi sokuchoboza ukuze uvimbele ukunsundu kwe-enzyme, uvimbele i-peach pulp ekushintsheni kombala, futhi uqinisekise ukuthi umkhiqizo wokugcina unombala wegolide okhanyayo.
2. Ukujusisha Nokucacisa: Thuthukisa Ukukhiqizwa Kwejusi Nokuzinza Komkhiqizo
Lesi sigaba sinquma ukusebenza kahle kokukhipha ijusi, ukuhanjiswa kokukhanya kwejusi eligxilile kanye nekhono lokulwa nokuna ngesikhathi sokuphelelwa yisikhathi.
- Ukukhishwa Kwejusi: Sebenzisa umshini wokunyathelisa ngesikulufo noma i-airbag ukuze ucubungule i-peach pulp, uthole isivuno sejusi esingaphezu kuka-70%. Inani elincane le-enzyme ye-pulp lingangezwa ngaphambi kokuyikhipha ukuze kusizwe ekuboleni i-pectin futhi kuthuthukiswe ukusebenza kahle kokukhishwa kwejusi.
- Ukususwa Kokuhlunga Okungafanele kanye Nezinsalela: Hlunga ijusi le-peach elikhishwe ngesihlungi se-mesh esingu-60 ~ 100 ukuze ususe i-fiber eluhlaza kanye nezinsalela ezinkulu ze-granular pulp, uthole ijusi le-peach eluhlaza elicwengekile ekuqaleni.
- Ukucaciswa Kwe-Enzymatic: Faka i-pectinase (0.0125% ~ 0.02%) + inani elincane le-amylase kujusi we-peach ongahluziwe, bese wenza i-enzyme hydrolysis ku-50 ~ 55℃ amahora angu-1 ~ 3 ukuze ubolise ngokuphelele i-pectin yama-macromolecular kujusi, ugweme ukuhlukaniswa kanye nemvula ngesikhathi sokugcina okulandelayo.
- Ukuhlunga Okuhle Nokuhlanzwa: Sebenzisa inqubo ehlanganisiwe yokuhlunga ipuleti nohlaka kanye ne-membrane ye-ultrafiltration (usayizi wembobo 0.5 ~ 0.8μm) ukuze ubambe ngokugcwele ama-colloid asele, ama-heteroprotein kanye nezinto eziqinile ezilengayo, ekugcineni uthole ijusi elicacile elinokudlulisa ukukhanya okuphezulu kanye nokuqina okuqinile.
3. Inqubo Yokugxilisa Ukugxila: Isixhumanisi Sobuchwepheshe Esiyinhloko
Kunezinqubo ezimbili eziyinhloko ezitholakalayo zokukhetha ngokuya ngokuma komkhiqizo, kanye nomgomo oyinhloko wokugwema ukulimala kwezinga lokushisa eliphezulu ezintweni ezinokunambitheka okuzwela ukushisa.
- Ukugxila Kwe-Vacuum Ezingashisi Kahle (Inqubo Ejwayelekile Ejwayelekile): Hlikihla bese ukhipha amanzi ngaphansi kwengcindezi encishisiwe ku-50~60℃ ngezinga le-vacuum elingu-0.08~0.095MPa, okwandisa izinto eziqinile ezincibilikayo zejusi le-peach kusukela ku-10%~12% yokuqala kuya ku-65%~70%. Le nqubo inciphisa kakhulu ukubhujiswa kwephunga le-peach ngokushisa okuphezulu futhi yehlisa izindleko zokugcina nezokuthutha ezilandelayo.
- Ukuhlushwa kwe-Membrane yokushisa okujwayelekile (Inqubo Yomkhiqizo Osezingeni Eliphezulu): Sebenzisa i-nanofiltration membrane ukuze uphelelwe amanzi emzimbeni ekushiseni okujwayelekile okungu-25 ~ 35℃, ngaphandle kokushintsha kwesigaba kuyo yonke inqubo. Izinga lokugcina izinto zokunambitheka namavithamini lingafinyelela ngaphezu kuka-98%, cishe akukho "ukunambitheka okuphekiwe", futhi ukusetshenziswa kwamandla kuphansi kunele-evaporation concentration yendabuko. Ifaneleka ukukhiqiza ijusi le-peach concentrated elinenani eliphezulu.
- Ukuthuthukiswa Kokubuyiselwa Kwephunga: Imigqa yokukhiqiza ephezulu ivame ukuhlonyiswa ngedivayisi yokubuyisa ukujiya kwezinto ezinuka kamnandi, ehlanganisa futhi iqoqe iphunga lepentshisi eliphumile ngesikhathi senqubo yokuhluza, bese ilifaka kujusi eliqediwe ukuze libuyisele iphunga lemvelo lamapentshisi amasha kakhulu.
4. Ukuxuba Nokususa Igesi: Lungiselela Ukunambitheka Nekhwalithi
Ngemva kokulungisa ushukela kanye ne-asidi kumanani aqondiwe ngokuya ngezindinganiso zomkhiqizo, yenza i-vacuum decompression degassing ukuze ususe i-oxygen encibilikisiwe kujusi, unciphise ukushintsha kombala we-oxidative kanye nokuwohloka kokunambitheka ngesikhathi sokugcina okulandelayo, futhi ugweme ukugqwala ngesikhathi sokugcwalisa okuthinta umphumela wokuvala.
5. Ukuhlanza nokugcwalisa: Qinisekisa Ukuphepha Nokuphila Isikhathi Eside
- Ukwelashwa Kokubulala Izinambuzane: Beka phambili ukubulala izinambuzane okushesha kakhulu kwe-UHT, kugcinwe imizuzwana embalwa ku-110 ~ 120℃, noma usebenzise ukubulala izinambuzane ku-95℃ imizuzwana engama-30, okungeke nje kubulale ngokuphelele amagciwane, kodwa futhi kunciphise umonakalo wokunambitheka kanye nokudla okunempilo.
- Ukugcwalisa Okungaphephile: Ngemva kokubulala amagciwane, faka ijusi elihlanganisiwe ezitsheni ezingangeni ukukhanya futhi ezivaliwe endaweni engaphephile. Umkhiqizo oqediwe ungagcinwa isikhathi eside ekushiseni okuphansi okungu-0 ~ 5℃ ngekhwalithi eqinile futhi akukho ukuwohloka okulula.
