Vitamin E (tocopherol), chikafu chekudya chakachengeteka chakabatanidzwa chakasimbiswa neFood and Agriculture Organization yeUnited Nations (FAO) uye World Health Organization (WHO) (INS nhamba: E307-309), yakaona kuwedzera kwakanyanya kwekushandiswa kwayo muzvokudya zvakagadziriswa mumakore achangopfuura. Zvinoenderana ne2024 data kubva kuChina Food Additives Association, musika wepasi rose saizi yevhitamini E yekuwedzera yasvika.2.36 mabhiriyoni emadhora ekuAmerica, neavhareji yegore yekukura kwe8.7%. Mabasa ayo makuru anosanganisira:

• Kuwedzera hupenyu hwesherufu:Nekudzivirira oxidation uye rancidity yemafuta nemafuta, hupenyu hwesherufu hwezvikafu zvakakangwa, nzungu, nezvimwe zvinogona kuwedzerwa ne30% kusvika 50%.
• Nutritional fortification:Inoshandiswa mucheche mucheche mukaka wehupfu, zviyo, nezvimwewo, kugadzirisa kukanganisa kwezvokudya zvemazuva ano.
• Alternative kune synthetic preservatives:Zvinoenderana ne "clean label" maitiro (semuenzaniso, 77% yevatengi muJapan vanofarira zvikafu zvine chaiwo antioxidants).

Nekudaro, nekuwanda kwechikafu chekupedzisira-chakagadzirwa (UPF), kuwedzera kwakanyanyisa kwevhitamini E uye njodzi dzayo dzehutano dzakonzerawo gakava munharaunda yezvidzidzo.

Kuongorora Kwehunyanzvi: Kubva kuLabhoritari kuenda kuMutsetse Wekugadzira

(1) Innovation in process uye dosage fomu

• Microencapsulation tekinoroji:Kuisa vhitamini E mune chingamu chiArabic kana cyclodextrin kugadzirisa kusagadzikana kwephotothermal (semuenzaniso, iyo oxidation uye kudzikira kweimwe mhando yemachipisi embatatisi yakadzikira ne62% mushure mekutora tekinoroji iyi).
• Natural extraction vs Chemical synthesis:
  • Masikirwo echisikigo (soya bean oiri deodorization distillate) inodhura (inenge katatu iyo yezvigadzirwa zvakagadzirwa), asi bioavailability yayo inosvika makumi maviri muzana.
  • Zvigadzirwa zveSynthetic (dl-α -tocopherol) account ye75% yemusika. Kuchenjerera kunofanira kubhadharwa kune njodzi yezvakasara zvinonyungudutsa (senge n-hexane).

(2) Yakakura data mune zvekushandisa mamiriro

Chikafu chikamu chekuwedzera huwandu (mg/kg) Basa Rakakosha Chikafu chemucheche chekuwedzera 50-200 Kurudzira kuvandudzwa kweneural Oiri yemuriwo 100-500 Dzivirira kuparara Frozen pastries 30-100 Inhibit oxidation yemafuta panguva yekuchengetwa kwechando Mitambo inovaka muviri 200-400 Regedza oxidative kusagadzikana mushure mekuita maekisesaizi.

Chengetedzo Kupokana: Kupokana muSainzi Nharaunda

(1) Kusiyana kwemitemo yemitemo

• KuChina, "GB 14880-2012" inotaura kuti huwandu hwekuwedzera huwandu mumafuta emuriwo i200mg/kg, ukuwo muEuropean Union, yakaregedzerwa kusvika 300mg/kg.
• Chinangwa chegakava: Chidzidzo che2023 muJapan chakawana kuti mbeva dzakadya yakawandisa vhitamini E yekuwedzera kwenguva yakareba yaive ne37% yakawedzera njodzi yechiropa fibrosis.

(2) Kuongorora pamusoro peVatengi 'Cognitive Kusanzwisisana

Ongororo yemibvunzo yakaitwa nevatori venhau vachibatsirana neShanghai Institute of Quality Inspection pakati pezviuru vakapindura inoratidza kuti:

• 68% yevatengi vanotenda kuti "ine vitamin E = hutano"
• 12% chete ndivo vaiziva nezvemuganho wepamusoro wekushivirira kwezuva nezuva (1000mg)
• 41% inokanganisa kuenzanisa antioxidant basa nekudzivirira kenza

Ramangwana reIndasitiri: Kuenzanisa Mabasa uye Njodzi

(1) Kutungamira kwebudiriro yetekinoroji

• Precise controlled-release tekinoroji:Iyo Ph-inopindura vhitamini E inotakura yakagadziriswa neInstitute of Food Science neTekinoroji, Chinese Academy yeSainzi, inogona kuwana yakanangwa kuburitswa mudumbu remukati.
• Biosynthesis nzira:Jiangnan University inoshandisa mbiriso yakagadzirwa nemhando yekugadzira yakasikwa vhitamini E, ichidzikisa mutengo ne40%.

(2) Mazano enyanzvi

• Muzvinafundo Li Hong anobva kuChinese Nutrition Society: "Zvakakosha kusimbisa fungidziro yemazuva ese yezvikafu zvine zvinowedzera."
• Aimbove chipangamazano weFDA Dr. Smith: "Vitamin E inofanirwa kukoshesa kuwanikwa kuburikidza nekudya, senzungu nemuriwo wemashizha akasvibira."

Mhedziso

Vitamin E, sekuwedzera kwechikafu, haingori tsigiro yakakosha yeindasitiri yechikafu yemazuva ano, asi inoratidzawo mutambo usingaperi pakati pekufambira mberi kwetekinoroji uye njodzi dzehutano. Maitirwo ekuenzanisa pakati pe "kuwedzera hupenyu hwesherufu" uye "kuchengetedza hutano" kunoda kuongororwa kwekubatana kwemapato ese ari mumaindasitiri.
