Phycocyanin yog cov xim ntuj muab rho tawm los ntawm Spirulina platensis thiab cov khoom siv raw.Spirulina yog ib hom microalgae kab lis kev cai nyob rau hauv qhib los yog tsev cog khoom.Thaum Lub Peb Hlis 1, 2021, spirulina tau ntxiv rau daim ntawv teev npe khoom noj khoom haus noj qab haus huv los ntawm lub xeev kev saib xyuas kev lag luam thiab Chaw Tswj Xyuas Kev Tswj Xyuas thiab tau ua tiav.Daim ntawv teev npe qhia tias Spirulina muaj cov txiaj ntsig ntawm kev txhim kho kev tiv thaiv kab mob thiab tsim nyog rau cov neeg muaj kev tiv thaiv qis.
Hauv Tebchaws Europe, phycocyanin yog siv los ua raw khoom ntawm cov khoom noj xim yam tsis muaj kev txwv (Raws li cov khoom noj xim xim, spirulina tsis muaj tus lej E vim tias nws tsis suav tias yog ib qho khoom ntxiv.Nws kuj yog siv los ua cov xim rau cov khoom noj khoom haus thiab tshuaj, thiab nws qhov ntau npaum li cas ntawm 0.4g mus rau 40g / kg, nyob ntawm seb cov xim qhov tob xav tau los ntawm cov zaub mov.
Extraction txheej txheem ntawm phycocyanin
Phycocyanin yog muab rho tawm los ntawm Spirulina platensis los ntawm kev siv lub cev me me, xws li centrifugation, concentration thiab pom.Tag nrho cov txheej txheem rho tawm raug kaw kom tsis txhob muaj kab mob.Cov extracted phycocyanin feem ntau yog nyob rau hauv daim ntawv ntawm hmoov los yog kua, thiab lwm yam excipients yog ntxiv (piv txwv li, trehalose yog ntxiv kom cov protein ntau ruaj khov, thiab sodium citrate yog ntxiv los kho pH Phycocyanin feem ntau muaj peptides thiab proteins (10-90). % qhuav qhov hnyav, suav nrog cov proteins complexed nrog phycocyanin), carbohydrates thiab polysaccharides (qhuav hnyav ≤ 65%), rog (qhuav hnyav <1%), fiber (qhuav hnyav <6%), ntxhia / tshauv (qhuav hnyav <6%) thiab dej (<6%).
Kev siv phycocyanin
Raws li cov ntaub ntawv ntawm Codex Alimentarius Commission, tus nqi ntawm phycocyanin noj los ntawm cov khoom noj thiab lwm yam khoom noj (nrog rau cov khoom xyaw zaub mov, cov khoom noj khoom haus thiab txheej txheej ntawm cov khoom noj khoom haus) yog 190 mg / kg (11.4 g) rau 60 kg neeg laus thiab 650 mg / kg (9.75 g) rau 15 kg menyuam.Pawg neeg txiav txim siab tias qhov kev noj haus no tsis yog teeb meem kev noj qab haus huv.
Nyob rau hauv European Union, phycocyanin yog siv los ua raw khoom ntawm cov khoom noj xim.
