Astaxanthin: Ngaphezu KweMibala – Isayensi Ngemuva Kwezokulima Kwezilwane Ezinempilo

It's one of the quiet truths of the seafood industry: that beautiful pink color in farmed salmon doesn't happen by accident. I learned this firsthand while visiting a fish farm in Norway, where the manager showed me two salmon fillets side by side. One was pale and unappealing, the other vibrantly pink. "This," he said, pointing to the pink fillet, "is whatastaxanthindoes."

Iningi labantu liyaziastaxanthinnjengomunye umkhiqizo wezempilo, kodwa ekwenzeni ubhontshisi, kube yinto eguqula umdlalo kweminyaka. “Sizobe singenamsebenzi ngaphandle kwalo,” kusho umphathi wefarm kimi ngokuqondile. “Uma i-salmon ibukeka beyinsomi, abantu bacabanga ukuthi ikhwalithi yayo ibi—abazoyithengi.”

Kodwa okwakubangela ukuthi abalimi abaningi baphazamiseke wukuthi umbala ongcono bekungukuphela kokwenzeka. Njengoba beqala ukuhlanganisaastaxanthinbaphakathi kokudla, babona ukuthi amafihlo awawathokozisi kuphela—babephila kahle, futhi. “Ngesikhathi sokuphuma kwe-virus esizini edlule, amabhodlela asebenzisa i-astaxanthin abona ukuphila okuphawulekayo,” kusho umphakathi wezinsikazi. “Kwakungesiyo into esayilindele ngesikhathi siqala ukuyisebenzisa.”

Lokhu kuhlanganyela okuphumelelayo kube yinto ebalulekile.astaxanthinkusuka ku “kufanele kube khona” kube “kufanele kube khona.” Lezi zinsuku, akukhona nje ngokwenza izinhlanzi zibe muhle—kukhona nokugcina ziphila phakathi nesikhathi sokukhula.

Kodwa inzuzo engalindelekile yafika ngendlela yokuphila kwezinkukhu nokukhiqiza. Abalimi babika hhayi kuphela ama-yolk anombala ongcono, kodwa nezindlela zokubeka ezihambisanayo kanye nezinkukhu eziphilile ngokujwayelekile.
