Kev txheeb xyuas ntau ntawm cov xim hauv cov txheej txheem refining ntawm cov zaub roj thiab cov rog
Cov roj zaub thiab cov rog tuaj yeem muab rho tawm los ntawm cov noob roj los ntawm leaching lossis nias, thiab cov roj zaub roj yog cov nplua nuj nyob rau hauv ntuj pigments, tshwj xeeb tshaj yog cov roj-soluble pigments xws li chlorophyll, lutein, zeaxanthin thiab -carotene yog cov feem ntau. Ntawm lawv, lutein thiab zeaxanthin yog tautomers, uas tuaj yeem tshem tawm cov dawb radicals, muaj zog antioxidant zog, txo cov kev pheej hmoo ntawm cov kab mob ntev thiab mob qog noj ntshav, tiv thaiv thiab kho cov ntshav qab zib, txo qhov kev puas tsuaj ntawm lub teeb xiav ntawm lub zeem muag thiab tiv thaiv thiab txo qis hnub nyoog. macular degeneration, thiab lwm yam -carotene yog precursor ntawm vitamin A, uas yog lub ntsiab ntawm vitamin A. Nws muaj zog antioxidant nyhuv thiab yuav ua rau kom lub cev tsis muaj zog ntawm tib neeg lub cev. Nws muaj cov nyhuv antioxidant muaj zog thiab tuaj yeem ua rau lub cev tsis muaj zog ntawm tib neeg lub cev, thiab muaj txiaj ntsig zoo los tiv thaiv qog noj ntshav. Txawm li cas los xij, cov xim tsaus heev yuav cuam tshuam rau qhov zoo ntawm cov rog thiab cov roj, thiab nws nyuaj rau ua kom tau raws li cov neeg siv khoom siv, thiab cov xim ntuj feem ntau tsis ruaj khov rau cov cua sov thiab nyuaj rau kev khaws cia hauv cov txheej txheem refining.
Kev tshuaj xyuas cov ntsiab lus pigment hauv cov roj sib txawv
Cov xim muaj pes tsawg leeg hauv ntau hom zaub roj thiab cov rog sib txawv. Cov ntsiab lus ntawm lutein thiab -carotene nyob rau hauv soybean crude roj yog qhov siab, xws li ntawm 2.85 mus rau 6.71 mg / kg thiab 2.45 txog 10.50 mg / kg, raws li; Cov ntsiab lus ntawm -carotene thiab chlorophyll nyob rau hauv rapeseed crude roj kuj yog siab, xws li ntawm 12.30 mus rau 49.90 mg / kg thiab 4.87 mus rau 26.30 mg / kg, raws li; cov ntsiab lus ntawm zeaxanthin thiab -carotene nyob rau hauv pob kws crude roj yog kuj siab. Cov ntsiab lus ntawm cov pob kws crude roj kuj siab nyob rau hauv thaj tsam ntawm 12.40 ~ 15.80 mg / kg thiab 4.75 ~ 5.55 mg / kg, feem; Tag nrho cov nyiaj ntawm plaub lub ntuj pigments nyob rau hauv soybean crude roj, canola crude roj thiab pob kws crude roj yog 7.28 ~ 24.38 mg / kg, 23.13 ~ 95.80 mg / kg rau soybean crude roj, 23.13 ~ 95.80 mg / kg rau canola crude roj thiab 17.93 ~ 23.73 mg / kg rau pob kws crude roj, feem. Tag nrho cov pigments nyob rau hauv rapeseed crude roj yog ho ntau dua li nyob rau hauv soybean crude roj thiab pob kws crude roj.
Kev tsom xam cov xim ntawm cov ntsiab lus ntawm cov roj zaub sib txawv thiab cov rog hauv txhua ntu
Cov xim tshem tawm cov roj zaub thiab cov rog nyob rau hauv ntu nruab nrab yog li ntawm 5.6 feem pua rau 38.3 feem pua rau lutein, 1.4 feem pua rau 35.1 feem pua rau zeaxanthin, 0.0 feem pua rau 19.1 feem pua rau -carotene, thiab 4.4 feem pua rau 41.9 feem pua rau chlorophyll hauv cov roj taum pauv, thiab 26.0 feem pua rau 92.9 feem pua rau lutein, 1.9 feem pua rau 43.8 feem pua rau zeaxanthin, 2.4 feem pua rau 20.2 feem pua rau -carotene, thiab 9.3 feem pua hauv chlorophyll rapeseed yog'i. 20.2 feem pua, chlorophyll 9.2 feem pua -22.2 feem pua, lutein 19.5 feem pua -42.3 feem pua, zeaxanthin 34.6 feem pua -43.5 feem pua, -carotene 5.2 feem pua -6.8 feem pua , chlorophyll 76.9 feem pua -93.7 feem pua hauv pob kws roj; tag nrho cov xim tshem tawm ntawm cov roj zaub thiab cov rog nyob rau hauv ntu decolorization yog 90.5 feem pua -100 feem pua rau lutein, 100 feem pua rau zeaxanthin, thiab 59.5 feem pua rau -carotene hauv cov roj taum pauv. 100 feem pua, -carotene 59.3 feem pua ~ 100 feem pua, chlorophyll 83.5 feem pua ~ 98.7 feem pua ntawm cov taum roj, 96.9 feem pua ~ 100 feem pua, 100 feem pua, -carotene 24.8 feem pua ~ 100 feem pua, chlorophyll 97.2 feem pua hauv cov roj 97.2 feem pua , 100 feem pua , -carotene 100 feem pua, chlorophyll 87.5 feem pua ~ 98.7 feem pua hauv pob kws roj. Chlorophyll 87.5 feem pua -98.9 feem pua ; Hauv cov roj deodorized, tshwj tsis yog chlorophyll, tag nrho lwm cov pigments tau qis dua qhov kev kuaj pom, thiab tag nrho cov kev tshem tawm ntawm chlorophyll nyob rau hauv deodorized seem yog 85.7 feem pua -98.7 feem pua rau cov roj taum pauv, 97.9 feem pua -99. 9 feem pua rau cov roj rapeseed, thiab 92.3 feem pua -98.9 feem pua rau pob kws roj. Tag nrho plaub lub ntuj pigments nyob rau hauv soybean roj decayed feem ntau ho nyob rau hauv lub decolorization seem; lutein nyob rau hauv canola roj decayed feem ntau ho nyob rau hauv lub neutralization seem, thiab lwm yam peb pigments decayed tseem ceeb nyob rau hauv lub decolorization seem; chlorophyll nyob rau hauv pob kws roj decayed feem ntau ho nyob rau hauv lub neutralization seem, thiab lwm yam peb pigments decayed tseem ceeb tshaj nyob rau hauv lub decolorization seem.
Cov xim muaj pes tsawg leeg thiab cov ntsiab lus ntawm peb cov roj zaub thiab cov rog sib txawv, tab sis muaj qee yam qauv hauv lawv cov ntsiab lus thiab muaj pes tsawg leeg: canola roj kuj nplua nuj nyob rau hauv pigments, tom qab ntawd los ntawm pob kws roj thiab taum roj; Lub sab saum toj ob pigment ratios nyob rau hauv cov roj crude yog soybean roj Lub sab saum toj ob pigments nyob rau hauv cov roj crude yog -carotene thiab lutein nyob rau hauv soybean crude roj, -carotene thiab chlorophyll nyob rau hauv canola crude roj, thiab zeaxanthin thiab -carotene nyob rau hauv pob kws crude roj. Qhov sib txawv ntawm cov xim xim ntawm cov roj zaub sib txawv thiab cov rog tuaj yeem piav qhia cov xim sib txawv rau qee qhov.
Cov pigment decay tiam sis ntawm peb cov zaub roj refining seem yog raws li nram no: plaub lub ntuj pigments nyob rau hauv soybean roj decayed feem ntau ho nyob rau hauv lub decolorization seem; lutein nyob rau hauv rapeseed roj decayed feem ntau ho nyob rau hauv lub neutralization seem, thaum lwm yam peb pigments decayed tseem ceeb tshaj nyob rau hauv lub decolorization seem; chlorophyll nyob rau hauv pob kws roj decayed tseem ceeb tshaj nyob rau hauv lub neutralization seem, thaum lwm yam peb pigments decayed tseem ceeb tshaj nyob rau hauv lub decolorization seem.
Los ntawm kev txheeb xyuas cov ntsiab lus ntawm plaub lub ntuj pigments nyob rau hauv peb cov roj zaub thiab cov rog nyob rau hauv seem refining thiab tshawb nrhiav lawv cov kev hloov pauv, nws muab txoj hauv kev txhim khu kev qha los ntsuam xyuas cov kev ua tiav thiab kev ua haujlwm nruab nrab ntawm cov roj zaub thiab cov rog.
