●Ke eng Vithamine A Acetate?
Retinyl Acetate, lebitso la lik'hemik'hale retinol acetate, foromo ea molek'hule C22H30O3, nomoro ea CAS 127-47-9, ke esterified derivative ea vithamine A. Ha e bapisoa le joala ea vithamine A, e matlafatsa botsitso ka ho itšoara ka esterification le ho qoba ho senyeha ha oxidative, ho fetoha lisebelisoa tsa bohlokoa tse tala meriana le lijong tsa lijo.
Vithamine A ea tlhaho e fumaneha haholo sebeteng sa liphoofolo le tlhapi, empa tlhahiso ea indasteri hangata e amohela motsoako oa lik'hemik'hale, joalo ka ho sebelisa β-ionone e le selelekela le ho e lokisa ka Wittig condensation reaction. Lilemong tsa morao tjena, theknoloji ea ho itokisa e tala e kang ultrasound-enhanced interfacial enzyme catalysis e hlahile, e ntlafatsa haholo ts'ebetso ea ho itšoara hantle le ho fokotsa tšilafalo, ho fetoha tataiso ea bohlokoa bakeng sa ntlafatso ea theknoloji ea indasteri.
Vithamine A acetateke phofo ea kristale e tšoeu ho isa ho e khanyang kapa mokelikeli oa viscous o nang le ntlha e qhibilihisang ea 57-58 ° C, ntlha e belang e ka bang 440.5 ° C, boima ba 1.019 g/cm³, le index ea refractive ea 1.547-1.555. E na le ho qhibiliha ha mafura haholo 'me e bonolo ho qhibiliha ka har'a lihlapolli tsa tlhaho tse kang ethanol le ether, empa e na le metsi a fokolang a ho qhibiliha,' me e hloka ho kenngoa ka microencapsulated ho ntlafatsa dispersibility ea eona lijong.
Mabapi le botsitso, vithamine A acetate e na le bothata ba leseli, mocheso le oksijene, 'me e hloka ho bolokoa hōle le leseli (2-8 ° C), le li-antioxidants tse kang BHT li eketsoa ho lelefatsa bophelo ba sethala. Bioavailability ea eona e holimo ho 80% -90%, 'me e fetoloa retinol ka enzymatic hydrolysis' meleng mme e nka karolo ho metabolism ea fisioloji.
