Yuav Ua Li Cas Kom Tau Txais Cov Khoom Zoo thiab Zoo Tshaj Plaws Hesperidin?

Hesperidin yog dab tsi?

Hesperidin 90 feem pua ​​​​Powderyog phytochemical cais raws li "bioflavonoid". Hesperidin feem ntau pom muaj nyob rau hauv cov txiv hmab txiv ntoo citrus, thiab zoo li lwm yam antioxidants, muaj cov txiaj ntsig zoo los tiv thaiv kab mob thiab cov txiaj ntsig zoo ntawm kev tiv thaiv kab mob vim tias nws muaj peev xwm tshem tawm cov dawb radicals. Flavonoids kuj tseem siv ntau lwm yam kev tiv thaiv, xws li tshuaj tiv thaiv hyperglycemic, tiv thaiv hyperlipidemic, thiab tiv thaiv qog noj ntshav.

Qhov xwm txheej tam sim no ntawm Kev Siv Citrus Resource yog dab tsi?

Hauv Suav teb, cov peev txheej citrus yog nplua nuj heev. Txawm li cas los xij, tam sim no kev siv citrus tsuas yog txwv rau nws cov txiv hmab txiv ntoo, nws cov peels tsis tau tag nrho tapping. Citrus tev suav txog 20 feem pua ​​​​ntawm tag nrho cov txiv hmab txiv ntoo hnyav. Txoj kev pov tseg feem ntau yog muab pov tseg citrus tev, uas ua rau ntau cov khib nyiab thiab tseem ua rau muaj kuab paug rau ib puag ncig. Ntxiv nrog rau cov dej noo, cellulose, thiab lignin, citrus peels kuj muaj ntau cov xim, pectin, hesperidin, thiab cov roj tseem ceeb. Yog li ntawd, ib txoj hauv kev tseem ceeb rau kev siv citrus tev yog ua raws li kev rho tawm ntawm cov khoom uas nws muaj, xws li extraction pigments, pectin, hesperidin, cov roj yam tseem ceeb, kev noj haus fiber ntau thiab lwm yam.

Yuav Ua Li Cas Kom Tau Txais Cov Khoom Zoo thiab Zoo Tshaj Plaws Hesperidin?

Cov txheej txheem peb qhia hauv peb tsab xov xwm yog ultrasonic-pab extraction ntawm hesperidin los ntawm citrus nyob rau hauv ua ke nrog nrog tsis xws li extraction hnyav, hnyav ntim, kub, extraction lub sij hawm, ultrasonic hwj chim, ultrasonic zaus, thiab lwm yam Solvent, zaus thiab kev kho mob kub tau soj ntsuam. Nws yog ib qho tseem ceeb rau kev txhim kho cov extraction yields ntawm hesperidin. Cov hauv qab no yog cov txheej txheem rau ultrasonic-pab extraction ntawm hesperidin:

A. Xaiv cov citrus tshiab, sau cov citrus tev kom qhuav, thiab pulverize los ntawm 50-mesh rau 60-mesh sieve kom tau citrus tev hmoov.

B. Cov citrus tev hmoov tau los ntawm kauj ruam A thiab 95 feem pua ​​​​ethanol ntawm 5 ~ 10 npaug ntawm qhov ntim ntawm citrus tev hmoov yog muab tso rau hauv cov khoom siv ultrasonic extraction, sib tov zoo, nqa tawm ultrasonic extraction 2 ~ 3 zaug. Lim thiab sib koom ua ke cov kev daws teeb meem los ntawm txhua qhov kev tshem tawm ultrasonic kom tau txais citrus tev extract. Lub zog ultrasonic ntawm txhua lub sijhawm yog 70W / cm²~ 80 ff/cm² , txhua ultrasonic extraction zaus yog 40 KHz ~ 60 KHz, txhua ultrasonic extraction kub tswj 40 degree C ~ 55 degree, txhua ultrasonic extraction lub sij hawm yog 30min ~ 90min.

C. Cov citrus tev extract tau nyob rau hauv cov kauj ruam B yog concentrated nyob rau hauv txo lub siab mus rau ib tug txheeb ze ntom ntawm 1. Kho cov PH ntawm citrus tev extract rau 3.5 ~ 4.5 nrog hydrochloric acid tov, thiab sawv ntsug rau crystallization nyob rau hauv 12-24 teev, ces lim kom tau crude hesperidin extract.

D. Dissolve cov crude hesperidin extract tau nyob rau hauv kauj ruam C nyob rau hauv distilled dej, do tusyees, muab tso rau ib tug macroporous adsorption resin kem, ces elute nrog 75 feem pua ​​​​ethanol, sau cov eluent thiab qhuav kom tau hesperidin.

Ua kom zoo dua ntawm kev siv tshuab ultrasonic los ntxiv dag zog rau kev rho tawm thiab kev sib cais tuaj yeem txhim kho qhov kev rho tawm thiab kev sib cais, txo lub sijhawm rho tawm, txuag cov nqi, thiab txawm tias txhim kho qhov zoo thiab cov txiaj ntsig ntawm cov khoom.
