Ukuhlaziywa kwemakethe okufinyeziwe kanye namathuba
Ukufinyeza uhlobo lwamafutha aqinile asetshenziswa ekucubungulweni kokudla lapho ingxenye eyinhloko kuyi-oyela yemifino noma amafutha ezilwane. Ukufinyeza kusetshenziswa kabanzi ekubhakeni, ekuthoseni nakwezinye izindawo zokucubungula ukudla, inhloso eyinhloko ukwandisa ukuqina nokunambitheka kokudla. Ngokuthuthuka kwemboni yokudla yomhlaba wonke, imboni yokufinyeza nayo iyakhula futhi ikhombisa ukuthambekela kokuhlukahluka kanye nekhwalithi ephezulu.
Ukubuka konke kwemakethe yokufinyeza yomhlaba wonke
Imakethe yokuncishiswa kwemikhiqizo emhlabeni wonke ibonise ukukhula okuqhubekayo eminyakeni yamuva nje, futhi izinga lemakethe likhule unyaka nonyaka. Ngokusho kombiko wocwaningo lwemakethe, izinto ezibangela imakethe yokuncishiswa kwemikhiqizo emhlabeni wonke yisidingo esikhulayo sezimpahla ezibhakiwe, intuthuko esheshayo yemboni yokucubungula ukudla, kanye nokuphishekela kwabathengi ukudla okuseqophelweni eliphezulu. Ikakhulukazi ezimakethe ezisafufusa, njengesifunda sase-Asia-Pacific, eLatin America nakwezinye izindawo, ngentuthuko yomnotho kanye nokuthuthukiswa kwezinga lokuphila, ukusetshenziswa kwemikhiqizo yokubhaka kanye nokudla okusheshayo kukhule kakhulu, okukhuthaza kakhulu ukwanda kwemakethe yokuncishiswa kwemikhiqizo.
Izitayela kanye nezinselele zemboni
1. Impilo kanye nokudla okunempilo: Njengoba imiqondo yokudla okunempilo ithandwa, abathengi bayaqaphela ukufushanisa okuqukethe ama-trans fatty acid kanye namafutha agcwele. Ngenxa yalokhu, imboni iyaqhubeka nokuthuthukisa nokukhuthaza i-trans fatty acid ephansi, imikhiqizo yokufushanisa amafutha agcwele, njengokusetshenziswa kwamafutha esundu, amafutha elanga, amafutha kasoya kanye nezinye izinto zokusetshenziswa ukuze kuthathelwe indawo amafutha ezilwane endabuko.
2. Ukuvikelwa kwemvelo kanye nokusimama: Abakhiqizi abaningi abanciphisa imfucuza sebeqalile ukugxila ekuvikelweni kwemvelo kanye nokusimama, ngokwenza ngcono izinqubo zokukhiqiza, ukunciphisa ukukhishwa kwekhabhoni kanye nokusebenzisa imithombo yamandla avuselelekayo ukuze kufezwe ukukhiqizwa okuluhlaza. Isibonelo, ukuphathwa okusimeme kochungechunge lokuhlinzekwa kwamafutha esundu sekuyinto egxile embonini.
3. Ukusungula izinto ezintsha kwezobuchwepheshe: Ubuchwepheshe bokucubungula obuthuthukisiwe busetshenziswe kabanzi ekuncishisweni komkhiqizo, njengokuguqulwa kwe-enzyme, ukukhishwa koketshezi olubucayi kakhulu, ukuhluzwa kwama-molecule kanye nobunye ubuchwepheshe, ukuthuthukisa ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza.
Imishini yokucubungula okufushane
Ukukhiqizwa kokufinyeza kuhilela izixhumanisi eziningi zenqubo eziyinkimbinkimbi futhi kudinga imishini ephezulu. Imishini eyinhloko ihlanganisa:
1. Imishini yokucwenga uwoyela: okuhlanganisa ukususa i-gum, ukususa i-asidi, ukususa umbala, ukususa iphunga kanye nezinye izinqubo zemishini, ezisetshenziselwa ukususa ukungcola kanye nephunga elibi ku-oyela ongahluziwe, ukuthuthukisa ikhwalithi yamafutha.
2. Imishini yokufaka i-hydrogenation: Uwoyela wemifino owuketshezi uguqulwa ube amafutha aqinile noma aqinile kancane ngenqubo yokufaka i-hydrogenation ukuze kuthuthukiswe ukuzinza nokuqina kwamafutha.
3. Imishini yokwenza ikristalu kanye nokupholisa: isetshenziselwa ukulawula inqubo yokwenza ikristalu yamafutha ukwakha isakhiwo sekristalu esifanele ukuthuthukisa izakhiwo zomzimba kanye nokuqina kokufinyeza (i-scraped surface heat exchanger, i-SSHE）.
4. Imishini yokuxuba nokuhlanganisa: hlanganisa izinhlobo ezahlukene zamafutha namafutha, bese uhlanganisa imikhiqizo ukuze uqinisekise ukuzinza kwekhwalithi (umshini we-pin rotor).
5. Imishini yokupakisha: esetshenziselwa ukupakisha isifinyezo esiqediwe, amafomu avamile afaka amabhokisi, amathini ensimbi, amabhakede epulasitiki, njll., ukuze kuhlangatshezwane nezidingo zamakhasimende ahlukene.
Umbono wesikhathi esizayo
Esikhathini esizayo, ngentuthuko yesayensi nobuchwepheshe kanye nezinguquko ezidingweni zabathengi, imboni yokufinyeza izoqhubeka nokuthuthuka ngokwempilo, ukuvikelwa kwemvelo kanye nobuhlakani. Ukuthuthukiswa kwezinto ezintsha zokusetshenziswa, ukusetshenziswa kwezinqubo zokukhiqiza eziluhlaza kanye nokwanda kobuchwepheshe bokukhiqiza obuhlakaniphile kuzoletha amathuba amaningi nezinselele embonini yokufinyeza. Izinkampani zidinga ukuhambisana nezitayela zemakethe futhi zihlale zisungula izinto ezintsha ukuze zihlangabezane nesidingo semakethe yomhlaba wonke semikhiqizo yokufinyeza esezingeni eliphezulu. Ukufinyeza uhlobo lwamafutha aqinile asetshenziswa ekucubungulweni kokudla lapho ingxenye eyinhloko kuyi-oyela yemifino noma amafutha ezilwane. Ukufinyeza kusetshenziswa kabanzi ekubhakeni, ekuthoseni nakwezinye izinkambu zokucubungula ukudla, inhloso eyinhloko ukwandisa ukuqina nokunambitheka kokudla. Ngokuthuthuka kwemboni yokudla yomhlaba wonke, imboni yokufinyeza nayo iyakhula futhi ikhombisa ukuthambekela kokuhlukahluka kanye nekhwalithi ephezulu.
