Siyini isitashi esishintshiwe?

Isitashi esilungisiwe sisho isitashi esishintshwe amakhemikhali noma ngokomzimba ukuze kuthuthukiswe ukusebenza kwaso kwezinhlelo ezithile zokusebenza. Isitashi, i-carbohydrate polymer ehlanganisa amayunithi eglucose, sichichima ezitshalweni eziningi futhi sisebenza njengomthombo omkhulu wamandla kubantu nasezilwaneni. Isitashi esishintshiwe sisetshenziswa kabanzi ezimbonini ezahlukahlukene, ezihlanganisa ukudla, ezemithi, izindwangu, kanye nokukhiqiza amaphepha. Nakhu ukubuka konke kwesitashi esilungisiwe:

Izindlela Zokushintsha:

1. Ukuguqulwa Kwamakhemikhali: Izindlela zamakhemikhali zibandakanya ukwelapha isitashi ngama-acids, ama-alkali, noma ama-enzyme ukuze kuguqulwe ukwakheka kwawo kwamangqamuzana. Izinqubo ezivamile zokuguqulwa kwamakhemikhali zifaka i-etherification, i-esterification, i-cross-linking, i-oxidation, ne-hydrolysis.
2. Ukuguqulwa Komzimba: Izindlela ezingokwenyama zibandakanya ukwelashwa kwemishini noma okushisayo ukuze kulungiswe izakhiwo ezingokomzimba zesitashi ngaphandle kokuguqulwa kwamakhemikhali. Lezi zindlela zifaka ukufudumeza, ukugunda, ukukhipha, kanye nekristalu.

Izici ze-Modified Starch:

• Ukujiya kanye Nokugaywa: Izitashi ezishintshiwe zibonisa izakhiwo ezithuthukisiwe zokujiya kanye ne-gelling uma kuqhathaniswa nesitashi somdabu, okuzenza izithasiselo ezibalulekile emikhiqizweni yokudla efana namasoso, amasobho, ama-gravies, nama-dessert.
• Ukuzinza: Izitashi ezishintshiwe zingase zibe nokuzinza okuthuthukisiwe kuzici ezifana nomjikelezo wokushisa, i-asidi, ukugunda, nokuncibilikisa, okuvumela ukusebenza okungcono ekucutshungulweni nasekugcinweni kokudla.
• Ukulawulwa Kwe-Viscosity: Isitashi esishintshiwe singalungiswa ukuze sinikeze amaphrofayili athile e-viscosity, okuvumela ukulawula okunembile kokuthungwa nokuvumelana kwemikhiqizo yokudla.
• Ukucaca: Ezinye izitashi ezishintshiwe zinikeza ukucaca okuthuthukisiwe kanye nokucaca ezixazululweni, okuzenza zifanelekele ukusetshenziswa emikhiqizweni yokudla ecacile noma ekhanyayo.
• I-Freeze-Thaw Stability: Isitashi esithile esishintshiwe sibonisa ukuzinza kweqhwa okuthuthukisiwe, okuwenza afanelekele ukusetshenziswa emikhiqizweni yokudla efriziwe.

Izicelo:

1. Imboni Yokudla: Isitashi esishintshiwe sisetshenziswa kakhulu njengezithako ezijiyayo, iziqinisi, ama-gelling agents, kanye nama-emulsifiers emikhiqizweni yokudla ehlukahlukene, okuhlanganisa amasoso, okokugqoka, amasobho, ama-dessert, izinto zokubhaka, nenyama egayiwe.
2. Ezemithi: Embonini yezemithi, isitashi esilungisiwe sisetshenziswa njengezibophezelo, izinqamuli, izigcwalisi, nama-ejenti akhipha okulawulwayo ekwenziweni kwamaphilisi namanye amafomu omthamo womlomo.
3. Izindwangu: Izitashi ezishintshiwe zisetshenziswa ekulinganisweni kwendwangu ukuze kuthuthukiswe amandla entambo, ukuthambisa, kanye nekhwalithi yendwangu phakathi nezinqubo zokuluka nokuqeda.
4. Ukwenziwa Kwephepha: Ekwenziweni kwamaphepha, isitashi esilungisiwe sisetshenziswa njengama-ejenti okulinganisa ubukhulu, ama-coating binders, nezithasiselo zangaphakathi ukuze kuthuthukiswe amandla ephepha, ukuphrinta, kanye nezakhiwo ezingaphezulu.
5. Izinamatheliso: Izitashi eziguquliwe zisetshenziswa njengezibophezelo kanye nezinamatheliso ezinhlelweni ezahlukene, okuhlanganisa ukwakhiwa kwe-paperboard laminating, corrugating, kanye neplywood.

Ukuphepha Nemithethonqubo:

• Isitashi esishintshiwe esisetshenziswa ekusetshenzisweni kokudla nemithi singaphansi kokuqondisa okulawulwayo futhi kufanele sithobelane namazinga okuphepha asungulwe ama-ejensi alawulayo afana ne-Food and Drug Administration (FDA) e-United States kanye ne-European Food Safety Authority (EFSA) e-European Union. .
• Lawa ma-ejensi alawulayo ahlola ukuphepha kwezitashi ezishintshiwe ngokusekelwe ezintweni ezifana nobumsulwa, ukwakheka, ukusetshenziswa okuhlosiwe, kanye nemithelela yezempilo engaba khona.

Isitashi esishintshiwe sidlala indima ebalulekile ezinhlobonhlobo zezimboni, ezinikeza izakhiwo ezithuthukisiwe zokusebenza kanye nokuguquguquka kwezinhlelo zokusebenza ezihlukahlukene. Ngokulungisa ukwakheka kwamangqamuzana esitashi, abakhiqizi bangakwazi ukulungisa izakhiwo zaso ukuze zihlangabezane nezimfuneko ezithile zokusebenza, okuholela ekuthuthukisweni kwekhwalithi yomkhiqizo, ukuzinza, nokwaneliseka kwabathengi.
