Daim ntawv thov
Qhov twg cov tawv nqaij uas muaj xim av raug suav hais tias zoo nkauj, tib neeg tab tom paub ntau ntxiv txog cov teebmeem tsis zoo ntawm lub hnub ci thiab qhov kev pheej hmoo ntawm mob qog noj ntshav ntawm daim tawv nqaij. Kev xav tau kom tau txais xim av zoo li ntuj yam tsis tau pw hauv tshav ntuj tab tom loj hlob tuaj. Dihydroxyacetone, lossis DHA, tau siv tau zoo ua tus neeg sawv cev rau kev tanning tus kheej tau ntau tshaj ib nrab xyoo pua. Nws yog cov khoom xyaw tseem ceeb hauv txhua yam kev npaj khoom siv rau kev tanning tsis muaj hnub ci, thiab suav hais tias yog cov khoom siv tanning tsis muaj hnub ci zoo tshaj plaws.
Ntuj qhov chaw
DHA yog 3-carbon qab zib koom nrog hauv carbohydrate metabolism hauv cov nroj tsuag siab dua thiab tsiaj los ntawm cov txheej txheem xws li glycolysis thiab photosynthesis. Nws yog ib yam khoom physiologic ntawm lub cev thiab yog suav tias yog nontoxic.
Molecular Structure
DHA tshwm sim raws li kev sib xyaw ntawm monomer thiab 4 dimers. Lub monomer yog tsim los ntawm cua sov los yog melting dimeric DHA los yog dissolving nws nyob rau hauv dej. Cov pob zeb monomeric rov qab mus rau cov ntaub ntawv dimeric li ntawm 30 hnub ntawm kev cia ntawm chav sov. Yog li ntawd, cov khoom DHA feem ntau nthuav tawm hauv daim ntawv dimeric.
Lub Browning Mechanism
Dihydroxyacetone tans ntawm daim tawv nqaij los ntawm kev khi rau amines, peptides thiab dawb amino acids ntawm txheej txheej ntawm lub stratum conrneum los tsim cov tshuaj tiv thaiv Maillard. Cov xim av "tan" tshwm sim li ntawm ob lossis peb teev tom qab daim tawv nqaij tiv tauj DHA, thiab tseem ua rau tsaus rau li ntawm rau teev. Qhov tshwm sim yog ib qho tseem ceeb tan thiab diminishes tsuas yog cov tuag hlwb ntawm horney txheej flake tawm.
Lub tan qhov kev siv yog nyob ntawm hom thiab thickness ntawm horny txheej. Qhov twg lub stratum corneum yog tuab heev (ntawm lub luj tshib, piv txwv li), lub tan yog khaus. Qhov twg cov horney txheej yog nyias (xws li ntawm lub ntsej muag) lub tan yog tsawg khaus.
