Vitamin B2 (Riboflavin)
Vitamin B2, tseem hu ua riboflavin, yog me ntsis soluble nyob rau hauv dej, ruaj khov nyob rau hauv nruab nrab los yog acidic tov nyob rau hauv cua sov.Nws yog ib tug muaj pes tsawg leeg ntawm cofactor ntawm daj enzyme lub luag hauj lwm rau xa hydrogen nyob rau hauv lub lom redox nyob rau hauv peb lub cev.
Cov Khoom Taw Qhia Cov khoom no yog cov khoom siv qhuav qhuav uas ua los ntawm cov kab mob microbial fermentation uas siv cov kua qab zib thiab cov poov xab extract ua cov khoom siv raw, thiab tom qab ntawd tau ua kom zoo dua los ntawm cov membrane pom, crystallization, thiab tshuaj tsuag kom qhuav.
Physical Properties Cov khoom no yuav tsum tau muab ntxiv rau cov tsiaj pub kom muaj lub cev noj qab haus huv, ua kom muaj kev loj hlob thiab kev loj hlob, thiab ua kom muaj kev ncaj ncees ntawm daim tawv nqaij thiab cov mucous membranes.Cov khoom yog daj mus rau xim av sib npaug siab fluidity particle nrog melting point 275-282 ℃, me ntsis tsw thiab iab, soluble nyob rau hauv dilute alkali kua, insoluble nyob rau hauv dej thiab ethanol.DryRiboflavin tseem ruaj khov tiv thaiv oxidant, acid thiab kub tab sis tsis alkali thiab Lub teeb uas yuav ua rau kom nrawm nrawm ntawm nws, tshwj xeeb tshaj yog hauv cov tshuaj alkaline lossis ultraviolet.Yog li nws tau qhia ntau heev tias cov khoom no yuav tsum raug kaw los ntawm lub teeb thiab nyob deb ntawm alkaline tshuaj nyob rau hauv premix los daws qhov tsis tsim nyog poob, ntxiv rau thaum muaj dej dawb nyob ib puag ncig - cov dej dawb ntau dua, qhov poob ntau dua.Txawm li cas los xij, Riboflavin muaj kev ruaj ntseg zoo yog tias nws pom cov hmoov qhuav hauv qhov tsaus ntuj.Txawm li cas los xij, cov txheej txheem pub pelleting thiab bulking ua rau muaj kev puas tsuaj rau Riboflavin- txog 5% mus rau 15% poob tus nqi los ntawm cov txheej txheem pelleting thiab txog 0 mus rau 25% los ntawm cov txheej txheem bulking.
