Daim ntawv thov
Qhov twg daim tawv nqaij tanned raug suav hais tias yog qhov txaus nyiam, tib neeg tau paub ntau ntxiv txog qhov teeb meem ntawm lub hnub ci thiab kev pheej hmoo ntawm daim tawv nqaij. Lub siab xav kom tau ib lub ntuj saib tan yam tsis muaj hnub ci loj tuaj. Dihydroxyacetone, los yog DHA, tau siv tau zoo ua tus neeg sawv cev ntawm tus kheej rau ntau tshaj li ib nrab xyoo pua. Nws yog cov khoom xyaw tseem ceeb nyob rau hauv tag nrho cov hnub tsis muaj tanning kev npaj kho tawv nqaij, thiab suav hais tias yog qhov zoo tshaj plaws hnub tsis muaj tanning additive.
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 crystals monomeric rov qab mus rau cov 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 nyob rau hauv ob los yog 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 hlwb tuag 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.
