Ukuhlaziywa kwejusi kusukela ekunciphiseni kuphela uhlobo olulodwa lwezithelo ekhaya ezinkampanini zamanye amazwe ezikhipha amasu ahlanganisiwe emhlabeni jikelele. Le mikhiqizo yejusi ikhiqizwa ezitshalweni ezinobuchwepheshe kakhulu zokuphatha ujusi, icutshungulwe futhi ifakwe emaphaketheni ayindathane.
Amajusi angathengiswa njengojusi wesithelo esisodwa (isb. Ijusi le-orange) noma angahlanganiswa namanye ama-juices ukukhulisa ubumnandi bawo, alungisa i-acidity, umbala noma ukunambitheka kwawo futhi andise izinhlobonhlobo zokudla komkhiqizo.
Imikhiqizo enosiwe ihlukaniswa ngokomthamo wejusi yezithelo yangempela equkethe.
Ukuhlukaniswa Kwejuso Yezithelo
Ukuhlukaniswa kwejusi yezithelo, ngokusho kweSouth African Fruit Juice Association (SAFJA), kungokulandelayo:
'Ijusi yezithelo entsha' iqukethe ujusi ongu-100% ongenazo izengezo ezivunyelwe. Kufanele ithengiswe kungakapheli amahora ama-2 kukhishwe.
I-'jusi yezithelo engafakiwe' ngujusi oyi-100% onezengezo ezivumelekile ezivunyelwe.
'Izithelo umpe' kufanele aqukethe amaphesenti amancane amajusi ezithelo, ivolumu liyahlukahluka ngezithelo ezihlukile.
Isibonelo, okungenani ujusi wama-50% uyadingeka kaphayinaphu, owolintshi, naartjie kanye ne-apula.
Kudingeka okungenani ijusi lama-35 - 40% ama-apricot (35%), peach kanye ne-pearl (40%) ngenkathi i-granadilla, i-guava, i-banana blackcurrant, i-papaya, i-litchi kanye nomango izithelo umpe udinga okungenani ama-20% ukuhlukaniswa kanjalo. Ijusi nelamula kalamula kufanele kube okungenani yi-12,5% yenhlanganisela ukuze ihlukaniswe njenge 'izithelo umpe'.
I-'Le squash yezithelo' kufanele ibe noshukela omncane wama-24% kwifomu elingafakwanga futhi u-6% (amaminithi) kwifomu. Elihlanjululwe ngenkathi 'isiphuzo sezithelo' kufanele okungenani sibe ne-6% ijusi.
Isiphuzo 'esinezithelo ezinongiwe' kwesinye isikhathi siqukethe isiphuzo sezithelo esingaphansi kuka-6%.
Izinhlobo zeJusi
Amajusi aziwa kahle futhi adumile njengawolintshi, amagilebhisi, uphayinaphu, i-apula, utamatisi kanye nokuxubha okusunguliwe kahle, kepha ama-jusi asezindaweni ezishisayo (isb. Amanzi kakhukhunathi, i-açaí ne-goji berry), ujusi wemifino (isb. Ikhukhamba ne-seedgrass) kanye nokuxubha kwejusi kuyakhula ngokuthandwa.
Eminye imikhiqizo enjusiwe isetshenziselwa izinjongo zokwelapha - izibonelo zifaka ujusi we-Aloe ferox nejusi kalamula.
Ijusi lingacaciselwa ukukhipha ama-solids futhi lithele umkhiqizo okhanyayo futhi okhanyayo, kepha abathengi abaningi abanempilo bangase bathande amajusi anefu ane-fiber yemvelo. Amajusi acacile adumile yi-apula, amagilebhisi kanye namajikijolo afana ne cranberry.
Ijusi lingafakwa kukhabhoni ukuze kufakwe i-fizz noma isetshenziswe njengesithako kumasoso, ama-cocktails, ama-marinade neziphuzo ezihlanganisiwe zezithelo ukukhulisa ukunambitheka kanye ne-acidity (isb. Lime nejusi kalamula).
Ijusi elicindezelwe ebandayo liyindlela enempilo kunazo zonke yejusi. Ngale nqubo, ujusi ukhishwa ngomshini we-hydraulic. Ngokuphambene nalokho, lapho kusetshenziswa umshini wokushicilela we-centrifugal, ama-blade asika futhi asonge umkhiqizo, okuholela ekwandeni kwezinga lokushisa nokubeka isithelo kummoya owengeziwe. I-oksijini iholela ku-oxidation lapho ama-B-amavithamini kanye novithamini C ezibucayi ikakhulukazi.
Amajusi acindezelwe ngokubandayo agcina amavithamini noma amaminerali wezithelo noma zemifino amaningi futhi awanawo ama-sweetenelter okwenziwa noma amakhambi asetshenziswa ngaphambi kwejusi.
Imixubo kaJusi
Akuzona zonke izithelo ezilungele ijusi yezithelo ejwayelekile futhi zingaphenduka zibe yi-puree eminyene lapho ikhiqizwa. I-Puree evela ezitsheni ezinjenge pearl, ibhanana, ama-apricots kanye nemango kudingeka ukuthi ihlanjululwe ngamanzi noma enye ijusi ukuze ikunikeze ukuguquguquka okuphuzwayo. Lezi zingqimba zezithelo eziwugqinsi zivame ukusetshenziswa kuma-smoothies, ama-cocktails, okhilimu beqhwa neminye imikhiqizo engezwe ngokubaluleka.
Amanye ama-juices afanelekile ukuwasebenzisa ekuxubeni ngenxa yokunambitha, ukuthungwa noma ukudinwa - i-beetroot, isanqante kanye ne-Aloe ferox engqondweni.
Amanye amajusi afakwa kuhlanganiswe ukufaka i-flavour, i-acidity, umbala, ukunambitha kanye nomkhiqizo wokugcina ohlanganisiwe. Ngenkathi ukufaka ama-juices athile kungahle kube nomphumela wokugcina; ijusi le-rhubarb (10 - 20%) lingakhawulela ukufiphala kwejusi le-apula.
