Vitamini E (tocopherol), chowonjezera chotetezeka cha chakudya chophatikizidwa ndi Food and Agriculture Organization of United Nations (FAO) ndi World Health Organization (WHO) (INS number: E307-309), yawona kuwonjezeka kwakukulu kwa ntchito yake mu zakudya zokonzedwa m'zaka zaposachedwa. Malinga ndi data ya 2024 yochokera ku China Food Additives Association, kukula kwa msika wapadziko lonse wa zowonjezera za vitamini E wafika.2.36 biliyoni madola aku US, ndi chiwongola dzanja chapakati pachaka cha 8.7%. Ntchito zake zazikulu ndi izi:

• Kuwonjezera moyo wa alumali:Mwa kupewa makutidwe ndi okosijeni ndi rancidity wa mafuta ndi mafuta, alumali moyo wa zakudya zokazinga, mtedza, etc. akhoza anawonjezera ndi 30% mpaka 50%.
• Kulimbitsa thanzi:Amagwiritsidwa ntchito mu ufa wa mkaka wa makanda, mbewu, ndi zina zotero, kuti apange zofooka za zakudya zamakono.
• Njira zina zosungirako zopangira:Mogwirizana ndi "zoyera zoyera" (mwachitsanzo, 77% ya ogula ku Japan amakonda zakudya zomwe zili ndi ma antioxidants achilengedwe).

Komabe, ndi kuchuluka kwa zakudya zopangidwa ndi ultra-processed (UPF), kuwonjezereka kwa vitamini E ndi kuopsa kwake kwa thanzi kwadzetsanso mikangano pakati pa ophunzira.

Kusanthula Kwaukadaulo: Kuchokera ku Laborator kupita ku Line Yopanga

(1) Kupanga zatsopano munjira ndi mawonekedwe a mlingo

• Ukadaulo wa Microencapsulation:Kuyika vitamini E mu chingamu cha Chiarabu kapena cyclodextrin kuti athetse kusakhazikika kwawo kwa kutentha (mwachitsanzo, makutidwe ndi okosijeni ndi kuwonongeka kwa mtundu wina wa tchipisi ta mbatata kudatsika ndi 62% mutagwiritsa ntchito ukadaulo uwu).
• Natural m'zigawo vs Chemical synthesis:
  • Magwero achilengedwe (mafuta a soya deodorization distillate) ndi okwera mtengo (pafupifupi kuwirikiza katatu kuposa zinthu zopangidwa), koma bioavailability yake ndi 20% yapamwamba.
  • Zopangira zopangidwa (dl-α -tocopherol) zimakhala ndi 75% ya msika. Chidwi chiyenera kuperekedwa ku chiopsezo cha zosungunulira zotsalira (monga n-hexane).

(2) Zambiri pazogwiritsa ntchito

Gawo la chakudya Kuonjezera kuchuluka kwa chakudya (mg/kg) Ntchito Yaikulu Chakudya chowonjezera cha ana 50-200 Limbikitsani chitukuko cha minyewa Mafuta a masamba 100-500 Pewani kuwonongeka kwa makeke oundana 30-100 Imatetezani kutulutsa mafuta m'malo oundana posungirako zakudya zamasewera 200-400 Pewani kupsinjika kwa okosijeni mukatha kuchita masewera olimbitsa thupi.

Kukangana kwa Chitetezo: Kulimbana mu Gulu la Sayansi

(1) Kusiyana kwa malamulo oyendetsera ntchito

• Ku China, "GB 14880-2012" imanena kuti kuchuluka kwa mafuta a masamba ndi 200mg/kg, pamene ku European Union, kumachepetsedwa kufika 300mg/kg.
• Cholinga cha mkanganowu: Kafukufuku wa 2023 ku Japan adapeza kuti mbewa zomwe zimadya kwambiri vitamini E zowonjezera kwa nthawi yayitali zinali ndi 37% chiopsezo cha chiwindi cha fibrosis.

(2) Kufufuza pa Kusamvetsetsana kwa Ogwiritsa Ntchito

Kafukufuku wopangidwa ndi atolankhani mogwirizana ndi bungwe la Shanghai Institute of Quality Inspection pakati pa anthu 1,000 omwe adafunsidwa akuwonetsa kuti:

• 68% ya ogula amakhulupirira kuti "ali ndi vitamini E = wathanzi"
• Ndi 12% yokha yomwe amadziwa malire apamwamba a kulolerana tsiku ndi tsiku (1000mg)
• 41% molakwika amafananiza ntchito ya antioxidant ndi kupewa khansa

Tsogolo la Makampani: Kulinganiza Ntchito ndi Zowopsa

(1) Chitsogozo chakupita patsogolo kwaukadaulo

• Tekinoloje yolondola yotulutsidwa:Chonyamulira cha Ph-responsive vitamin E chopangidwa ndi Institute of Food Science and Technology, Chinese Academy of Sciences, chikhoza kukwaniritsa kumasulidwa kwachindunji m'matumbo.
• Njira ya biosynthesis:Yunivesite ya Jiangnan imagwiritsa ntchito mitundu yopangidwa ndi yisiti kuti ipange vitamini E wachilengedwe, kuchepetsa mtengo ndi 40%.

(2) Malingaliro a akatswiri

• Pulofesa Li Hong wochokera ku Chinese Nutrition Society: "Ndikofunikira kulimbikitsa chiwerengero cha zakudya zatsiku ndi tsiku za zakudya zomwe zili ndi zowonjezera."
• Mlangizi wakale wa FDA Dr. Smith: "Vitamini E iyenera kukhala patsogolo kuti ipezeke mwa zakudya, monga mtedza ndi masamba obiriwira."

Mapeto

Vitamini E, monga chowonjezera cha chakudya, sichiri chothandizira chofunikira pamakampani amakono a zakudya, komanso amasonyeza masewera osatha pakati pa kupita patsogolo kwa teknoloji ndi kuopsa kwa thanzi. Momwe mungakhazikitsire bwino pakati pa "kukulitsa moyo wa alumali" ndi "kuteteza thanzi" kumafuna kuwunika kogwirizana kwa magulu onse amakampani.
