Piv nrog vitamin A cawv, nws txhim khu kev ruaj ntseg los ntawm esterification cov tshuaj tiv thaiv thiab tsis txhob oxidative decomposition, ua ib qho tseem ceeb raw khoom nyob rau hauv cov tshuaj pleev ib ce.
Ntuj vitamin A feem ntau pom muaj nyob rau hauv cov tsiaj lub siab thiab ntses, tab sis kev lag luam ntau lawm feem ntau txais cov tshuaj synthesis, xws li siv β-ionone ua tus precursor thiab npaj nws los ntawm Wittig condensation cov tshuaj tiv thaiv. Nyob rau hauv xyoo tas los no, ntsuab npaj technologies xws li ultrasound-enhanced interfacial enzyme catalysis tau tshwm sim, ho txhim kho cov tshuaj tiv thaiv efficiency thiab txo cov pa phem, ua ib tug tseem ceeb kev taw qhia rau kev lag luam technology hloov khoom dua tshiab.
Vitamin A acetateyog ib tug dawb mus rau lub teeb daj crystalline hmoov los yog viscous kua nrog ib tug melting point ntawm 57-58 ° C, boiling point ntawm txog 440.5 ° C, ib tug ceev ntawm 1.019 g / cm³, thiab ib tug refractive index ntawm 1.547-1.555. Nws muaj cov roj solubility tseem ceeb thiab yooj yim soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether, tab sis muaj cov dej tsis zoo, thiab yuav tsum tau microencapsulated los txhim kho nws cov dispersibility hauv cov zaub mov.
Hais txog kev ruaj ntseg, vitamin A acetate yog rhiab heev rau lub teeb, cua sov thiab oxygen, thiab yuav tsum tau muab cia kom deb ntawm lub teeb (2-8 ° C), thiab antioxidants xws li BHT yog ntxiv rau lub neej txee. Nws bioavailability yog siab li 80% -90%, thiab nws hloov mus rau hauv retinol los ntawm enzymatic hydrolysis nyob rau hauv lub cev thiab koom nyob rau hauv physiological metabolism.
