National bekendtg\u00f8relse<\/strong><\/p>\n

Den 26. maj 2008 udstedte sundhedsministeriet bekendtg\u00f8relsen om godkendelse af 7 nye ressourcef\u00f8devarer, herunder Lactobacillus Acidophilus (MOH Announcement No. 12 of 2008), som formelt godkendte luteinester som en ny ressourcef\u00f8devare og stillede f\u00f8lgende krav til dens sammens\u00e6tning, kilde, proces, anvendelsesomr\u00e5de, serveringsst\u00f8rrelse og kvalitetsspecifikationer:<\/p>\n

\"\"<\/p>\n

Karakterisering af in vivo-omdannelsen af luteinestere<\/strong><\/p>\n

Under ford\u00f8jelsen hydrolyserer kroppen effektivt luteinestere og frigiver frit lutein, som derefter optages i blodbanen.<\/p>\n

Unders\u00f8gelser har vist, at indtagelse af luteinestere \u00f8ger luteinniveauet i blodet og i nethindens makula. Optagelsen af carotenoider, herunder lutein, i kroppen er en proces i flere trin. Denne proces er den samme som for andre fedtopl\u00f8selige komponenter i kosten.<\/p>\n

Derfor kan lutein indtages med fedt. Omdannelsen af luteinestere til lutein er en naturlig fysiologisk proces i kroppen. Videnskabelig st\u00f8tte og klinisk evidens Luteinester er blevet anerkendt af det videnskabelige team som en af de sikre kilder til lutein.<\/p>\n

Funktioner af luteinestere<\/strong><\/p>\n

Luteinesters farvende effekter<\/strong><\/p>\n

Naturlig luteinester er en vigtig carotenoid fedtsyreester, hovedkonfigurationen er all-trans, med C = C lang k\u00e6de af farvegruppen, der viser str\u00e5lende gylden gul, der er ingen aktiv hydroxylgruppe p\u00e5 begge sider, s\u00e5 det bestemmer ogs\u00e5, at luteinesteren er en slags f\u00e5 meget stabilt f\u00f8devarefarvemiddel.<\/p>\n

Det er meget stabilt over for lys, varme og luft og kan bruges i vid udstr\u00e6kning i f\u00f8devarer, drikkevarer, kosmetik og andre applikationer med brede anvendelsesmuligheder. Samtidig kan det laves til vandopl\u00f8seligt farvestof efter emulgering. Naturlig luteinester vil erstatte kemisk syntetiserede farvestoffer af f\u00f8devarekvalitet og forbedre folks sundhed.<\/p>\n

Forebyggelse af ADM-brug<\/strong><\/p>\n

En vigtig biologisk funktion af lutein er at beskytte nethinden mod UV-skader. I \u00f8jeblikket er aldersrelateret makuladegeneration (ADM) globalt set den f\u00f8rende blinde \u00f8jensygdom hos mennesker over 65 \u00e5r.<\/p>\n

Efter indtagelse i menneskekroppen hydrolyseres naturlige lutein- og zeaxanthinestere til den frie form af lutein og zeaxanthin ved hj\u00e6lp af menneskelig lipase. De aflejres i h\u00f8j koncentration i makula i den menneskelige fundus, som kan fungere som en absorber af n\u00e6r-ultraviolet bl\u00e5t lys, og har en beskyttende effekt ved at fange frie radikaler, forebygge eller reducere skader for\u00e5rsaget af oxidation og frie radikaler p\u00e5 nethinden, hvilket effektivt kan reducere forekomsten af ADM.<\/p>\n

Forbedring af immunforsvaret<\/strong><\/p>\n

Nylige unders\u00f8gelser har vist, at tilskud af lutein i kroppen fremmer antigenstimulerede lymfocytproliferative reaktioner og kan p\u00e5virke det funktionelle udtryk af celleoverflademolekyler p\u00e5 dyreniveau som helhed. Luteins modulerende effekt p\u00e5 cellul\u00e6r immunitet kommer hovedsageligt til udtryk i dets forhold til apoptose og genregulering.<\/p>\n

Hudpleje og hjertebeskyttelse<\/strong><\/p>\n

Som en st\u00e6rk antioxidant kan luteolinester h\u00e6mme aktiviteten af reaktive iltradikaler og kan forhindre \u00f8del\u00e6ggelse af normale hudceller af reaktive iltradikaler. Derfor kan luteinestere laves til en r\u00e6kke forskellige hudplejeprodukter og kosmetik, som bruges til at beskytte hudens sundhed og forhindre hudskader.<\/p>\n

Nogle unders\u00f8gelser har vist, at mennesker, der regelm\u00e6ssigt indtager carotenoider, har en reduceret risiko for hjerte-kar-sygdomme. I 1994 fandt Morrs et al. ud af, at blodets indhold af carotenoider var omvendt relateret til risikoen for at udvikle koronar hjertesygdom.<\/p>\n

Anvendelse af luteinestere i f\u00f8devarer<\/strong><\/p>\n

Anvendelser i almindelige f\u00f8devarer<\/strong><\/p>\n

Luteinestere kan bruges i bagv\u00e6rk, mejeriprodukter, drikkevarer, spiseklare morgenmadsprodukter, frosne drikkevarer, krydderier og konfekture, men ikke i f\u00f8devarer til sp\u00e6db\u00f8rn og sm\u00e5b\u00f8rn. Doseringen er \u226412 mg\/dag.<\/p>\n

Anvendelse i helsekost<\/strong><\/p>\n

If\u00f8lge data fra State Food and Drug Administration er der i \u00f8jeblikket 265 indenlandske helsekostprodukter med luteinester som det vigtigste r\u00e5materiale, og den p\u00e5st\u00e5ede sundhedsfunktion er hovedsageligt at lindre visuel tr\u00e6thed.<\/p>","protected":false},"excerpt":{"rendered":"
