I-Vitamin E (i-tocopherol), isengezo sokudla esiphephile esiqinisekiswe ngokuhlanganyela yi-Food and Agriculture Organization yeZizwe Ezihlangene (FAO) kanye ne-World Health Organization (WHO) (inombolo ye-INS: E307-309), ibone ukwanda okukhulu kwesicelo sayo ekudleni okugayiwe eminyakeni yamuva. Ngokusho kwedatha yango-2024 evela ku-China Food Additives Association, usayizi wemakethe yomhlaba wonke wezithasiselo zikavithamini E usufinyelele.2.36 billion wamadola aseMelika, ngesilinganiso sokukhula saminyaka yonke esingu-8.7%. Imisebenzi yayo eyinhloko ihlanganisa:

• Inweba impilo yeshelufu:Ngokuvimbela i-oxidation kanye ne-rancidity yamafutha namafutha, impilo yeshalofu yokudla okuthosiwe, amantongomane, njll. inganwetshwa ngo-30% kuya ku-50%.
• Ukuqinisa ukudla okunomsoco:Isetshenziswa kufomula yobisi lwezinsana oluyimpushana, okusanhlamvu, njll., ukuze kulungiswe ukusilela kokudla kwesimanje.
• Okunye okuhlukile kuma-synthetic preservatives:Ngokuvumelana nethrendi "yelebula ehlanzekile" (isibonelo, abathengi abangu-77% e-Japan bakhetha ukudla okuqukethe ama-antioxidants emvelo).

Kodwa-ke, ngokwanda kokudla okucutshungulwe kakhulu (i-UPF), ukwengezwa ngokweqile kukavithamini E kanye nobungozi bezempilo obungase bube khona nakho kudale impikiswano emphakathini wezemfundo.

Ukuhlaziywa Kwezobuchwepheshe: Kusukela Elabhorethri kuya Emgqeni Wokukhiqiza

(1) Ukuqamba okusha kwinqubo kanye nefomu lomthamo

• Ubuchwepheshe be-Microencapsulation:Ukuhlanganisa uvithamini E ngeshingamu yesi-Arabic noma i-cyclodextrin ukuze kubhekwane nokungaqini kwe-photothermal (isibonelo, izinga le-oxidation kanye nokuwohloka kohlobo oluthile lwama-chips amazambane lehle ngo-62% ngemva kokwamukela lobu buchwepheshe).
• Ukukhishwa kwemvelo vs ukuhlanganiswa kwamakhemikhali:
  • Umthombo wemvelo (i-soybean oil deodorization distillate) uyabiza (cishe ngokuphindwe kathathu kunemikhiqizo eyenziwe), kodwa i-bioavailability yawo iphakeme ngo-20%.
  • Imikhiqizo yokwenziwa (i-dl-α -tocopherol) yenza ama-75% emakethe. Kufanele kuqashelwe ubungozi bezincibilikisi eziyinsalela (njenge-n-hexane).

(2) Idatha enkulu ezimeni zohlelo lokusebenza

Inani elingeziwe lesigaba sokudla (mg/kg) Umsebenzi Oyinhloko Ukudla okuhambisanayo komntwana 50-200 Khuthaza ukuthuthuka kwemizwa Amafutha emifino 100-500 Vimbela ukubola Amakhekhe aqandisiwe 30-100 Vimba ukukhishwa kwe-oxidation kawoyela ngesikhathi sokugcinwa okuqandisiwe Ukudla okunomsoco wezemidlalo 200-400 Yehlisa ingcindezi ye-oxidative ngemva kokuzivocavoca

Izingxabano Zokuphepha: Ukungqubuzana Emphakathini Wesayensi

(1) Umehluko kumazinga okulawula

• E-China, i-"GB 14880-2012" ibeka ukuthi inani eliphakeme lokungezwa emafutheni emifino lingama-200mg/kg, kanti e-European Union, lixegisiwe libe ngu-300mg/kg.
• Ukugxila kwempikiswano: Ucwaningo lwango-2023 eJapan lwathola ukuthi amagundane adle izithasiselo ze-vitamin E ngokweqile isikhathi eside abe nengozi eyandayo engama-37% ye-fibrosis yesibindi.

(2) Uphenyo Ngokungaqondi Ngokuqonda Kwabathengi

Inhlolovo yohlu lwemibuzo eyenziwe izintatheli ngokubambisana ne-Shanghai Institute of Quality Inspection phakathi kwabaphenduli abayi-1,000 ikhombisa ukuthi:

• I-68% yabathengi ikholelwa ukuthi "iqukethe i-vitamin E = enempilo"
• Bangu-12% kuphela ababewazi umkhawulo ophezulu wokubekezelela kwansuku zonke (1000mg)
• Ama-41% ngephutha alinganisa umsebenzi we-antioxidant nokuvimbela umdlavuza

Ikusasa Lemboni: Ukulinganisa Imisebenzi kanye Nezingozi

(1) Isiqondiso sokuthuthuka kwezobuchwepheshe

• Ubuchwepheshe obunembayo bokukhishwa okulawulwayo:I-Ph-responsive vitamin E carrier eyakhiwe yi-Institute of Food Science and Technology, i-Chinese Academy of Sciences, ingafinyelela ukukhululwa okuhlosiwe epheshaneni lamathumbu.
• Indlela ye-Biosynthesis:I-Jiangnan University isebenzisa izinhlobo ze-yeast engineered ukukhiqiza i-vitamin E yemvelo, yehlisa izindleko ngama-40%.

(2) Ukusikisela kochwepheshe

• USolwazi uLi Hong ovela e-Chinese Nutrition Society: "Kuyadingeka ukuqinisa ilebula yokulinganisa ukudla kwansuku zonke yokudla okuqukethe izithasiselo."
• Owayengumeluleki we-FDA uDkt. Smith: "I-Vitamin E kufanele ibekwe phambili ukuze itholakale ngokudla, njengamantongomane nemifino enamaqabunga aluhlaza."

Isiphetho

I-Vitamin E, njengesengezo sokudla, ayilona nje ukusekelwa okubalulekile kwemboni yesimanje yokudla, kodwa futhi ibonisa umdlalo waphakade phakathi kwenqubekelaphambili yezobuchwepheshe kanye nezingozi zezempilo. Indlela yokulinganisa phakathi "kokwelula isikhathi seshelufu" kanye "nokuvikela impilo" kudinga ukuhlola okuhlanganyelwe kwazo zonke izinhlangothi zochungechunge lwezimboni.
