Lycopeneyog cov rog ua haujlwm tau yooj yim nrog cov txiaj ntsig zoo hauv kev txhim kho thiab muaj ntau yam kev ua haujlwm ntawm lub cev. Txawm li cas los xij, lycopene muaj kev ua haujlwm tsis zoo thiab tsis muaj dej txaus. Tam sim no, feem ntau ntawm cov tebchaws thiab txawv teb chaws siv tib lub macromolecular thauj khoom los tsim cov txheej txheem xa khoom, thiaj li ua tiav kev thauj khoom thiab tswj kev tso tawm cov rog-soluble zaub mov ua haujlwm yam. Piv txwv, qee cov khoom siv macromolecular (cais cov protein protein, gelatinized pob kws hmoov txhuv nplej siab, thiab lwm yam) tau siv los ua tus nqa khoom los npaj microcapsules, nanoemulsions, thiab nanoliposomes txhawm rau txhawm rau thiab thauj cov khoom xyaw ua haujlwm, nrog kev pab ntawm cov kab ke tshwj xeeb no. Kev thauj cov tshuaj nquag hauv lub cev.
Wang Qingyu, Wang Mengyao, Chen Lei* ntawm Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb Lub Neej, Anhui University, Anhui Qhov Ntsuas Laboratory ntawm Ecological Engineering thiab Biotechnology, thiab lwm tus tau tsim pectin/sodium caseinate sib xyaw ua ke xa khoom nrog lycopene los kawm cov teebmeem ntawm lycopene Ntxiv rau lycopene encapsulation efficiency; dhau los ntawm Fourier hloov cov duab hluav taws xob tsom (FT-IR), xa hluav taws xob tsom iav (TEM), ntsuas kub thermogravimetric (TGA), ntsuas qhov sib txawv ntsuas calorimetry (DSC) ntsuas rau ternary sib xyaw Cov yam ntxwv ntawm lycopene hais, kev tshuaj xyuas ntawm qhov faib me me faib, cov qauv tshuaj thiab pom tseeb morphology ntawm complex; kev tsim kho hauv vitro sim sim plab thiab qauv zom zaub mov, nrog rau tus lej nkag thiab chaw thau khoom raws qhov ntsuas, los kawm txog cov txiaj ntsig ntawm lycopene ntawm qhov sib txawv pH qhov tseem ceeb thiab Kev tso tawm tus cwj pwm ntawm ntau qhov sib txawv ntawm txoj hnyuv zom ua kua (sim ua kua txiv plab, kua txiv hauv plab) yog ntsuas los txiav txim siab tso tawm cov txiaj ntsig ntawm lycopene, thiab lub plab zom zaub mov tswj kev tso tawm ntawm lycopene tau tham ua ntej.
Raws li qhov xwm txheej tias qhov sib piv loj ntawm lycopene/binary complex yog 10%, qhov sib piv loj ntawm pectin/sodium caseinate tau suav ua 10%, 20%, 30%, 40%raws li qhov nqus ntawm txhua tus qauv ntawm nthwv dej ntawm 471 nm ua. Kev suav tus lej ntawm lycopene ntawm%yog 95.74%, 96.37%, 93.63%, 93.15%, feem. Thaum qhov sib piv sib piv ntawm pectin/sodium caseinate yog 20%, kev sib sau tus nqi ntawm lycopene los ntawm binary complex Tus nqi siab tshaj.
Kev tsim kho cov txiaj ntsig ntawm pectin/sodium caseinate sib xyaw ua ke
Raws li qhov xwm txheej tias qhov sib piv loj ntawm pectin/sodium caseinate yog 20%, kev suav yog ua raws qhov nqus ntawm txhua qhov piv txwv ntawm lub nthwv dej ntawm 471 nm, thiab tus nqi thauj khoom yog 4%, 8%, 10%, 12%, 16%. Kev suav tus lej ntawm lycopene los ntawm cov khoom sib xyaw yog 85.30%, 96.93%, 93.09%, 79.70%, 84.68%, thiab cov txiaj ntsig tau qhia tias thaum tus nqi thauj khoom, uas yog, lycopene/binary compound yog 8%, binary compound kev tso tus lej ntawm lycopene yog qhov siab tshaj.
