Anthu padziko lonse lapansi amakonda kuwala kwa dzuwa, J. Lo, komwe kumawala kuchokera paulendo wapamadzi monga momwe munthu wina amakondera—koma sitikonda kuwonongeka kwa dzuwa komwe kumabwera chifukwa cha kuwala kumeneku. Onani kukongola kwa munthu wodzipaka utoto. Kaya ndi botolo kapena mankhwala opopera m'malo osambira, mutha kukhala otsimikiza kuti njirayo ili ndi dihydroxyacetone. Dzinali ndi lokoma kwambiri, ndichifukwa chake dihydroxyacetone nthawi zambiri imadziwika kuti DHA.
DHA ndi chinthu chapadera kwambiri padziko lonse lapansi pankhani ya zinthu zokongola, chifukwa choyamba, imapezeka mu gulu limodzi lokha la zinthu, ndipo chachiwiri, ndi chinthu chokhacho chomwe chingathe kuchita zomwe imachita. Pitirizani kuwerenga kuti mudziwe momwe utoto wonyengawo umakhalira.
DIHYDROXYACETONE
Mtundu wa Zosakaniza: Shuga
UBWINO WAPADERA: Zimayambitsa kusintha kwa mankhwala pakhungu zomwe zimapangitsa kuti maselo awoneke ngati akuda.1
NDANI AYENERA KUGWIRITSA NTCHITO: Aliyense amene akufuna kuoneka ngati wachikasu popanda kuwononga dzuwa. DHA nthawi zambiri imaloledwa bwino ndi anthu ambiri, ngakhale nthawi zina ingayambitse matenda a khungu, akutero Farber.
Kodi mungagwiritse ntchito kangati: DHA imayamba kuoneka ngati yakuda mkati mwa maola 24 ndipo imatha mpaka sabata imodzi, pafupifupi.
IMAGWIRA NTCHITO BWINO NDI: Zosakaniza zambiri zonyowetsa madzi, zomwe nthawi zambiri zimaphatikizidwa ndi DHA mu zinthu zodzipaka tokha, makamaka zonyowetsa ndi seramu, akutero Farber.
MUSAGWIRITSE NTCHITO PA: Alpha hydroxy acids imafulumizitsa kusweka kwa DHA; ngakhale kuti ndi njira yabwino yochotsera khungu lanu mukakonzeka, musagwiritse ntchito mukamagwiritsa ntchito self-tanner.
Kodi Dihydroxyacetone N'chiyani?
“Dihydroxyacetone, kapena DHA monga momwe imatchulidwira kawirikawiri, ndi shuga wopanda mtundu womwe umagwiritsidwa ntchito m'makina ambiri odzipaka tokha,” akutero Mitchell. Ikhoza kupangidwa mwa kupanga kapena kuchokera ku shuga wosavuta womwe umapezeka mu beets kapena nzimbe. Chenjezo losangalatsa: Ndi chinthu chokhacho chomwe chavomerezedwa ndi FDA ngati chodzipaka tokha, akutero Lam-Phaure. Ponena za zinthu zokongoletsera, mungazipeze mu makina odzipaka tokha okha, ngakhale nthawi zina zimagwiritsidwanso ntchito popanga vinyo, akutero Mitchell.
Momwe Dihydroxyacetone Imagwirira Ntchito
Monga tanenera, ntchito yayikulu ya DHA (yomwe ndi yowerengera yokha) ndikupanga mdima kwakanthawi pakhungu. Kodi imachita bwanji izi? Nthawi yoti mukhale bwino komanso omasuka kwa kanthawi kochepa, chifukwa zonse zimadalira momwe Maillard amachitira. Ngati mawuwa akumveka odziwika bwino, mwina chifukwa mwina munawamva mu kalasi ya chemistry ya sekondale, kapena pamene mukuyang'ana Food Network. Inde, Food Network. "Maillard reaction ndi mankhwala omwe amadziwikanso kuti non-enzyme browning—ndi chifukwa chake nyama yofiira imafiirira ikaphika," akufotokoza Lam-Phaure.
Tikudziwa kuti n'zachilendo pang'ono kuyerekeza nyama yokazinga ndi yodzipaka tokha, koma timvereni. Ponena za khungu, Maillard reaction imachitika pamene DHA imagwirizana ndi ma amino acid m'mapuloteni a maselo a khungu, zomwe zimapangitsa kuti pakhale melanoids, kapena utoto wa bulauni, Lam-Phaure akufotokoza.1 Izi zimapangitsa kuti munthu azioneka ngati wachikasu.
Ndikofunika kunena kuti izi zimachitika kokha mu khungu la epidermis, lomwe ndi pamwamba pa khungu, ndichifukwa chake kudzipaka tokha sikumakhala kosatha.1 Maselo ofiirawo akangotuluka, mawonekedwe amdimawo amatha. (Ndichifukwa chakenso kuchotsa DHA ndikofunikira kwambiri; zambiri za izi posachedwa.)
