It's a glycoprotein called miraculin, a naturally occurring thing. It still freaks me out every time I eat it, but it has a unique ability to mask certain taste receptors on your tongue, so that primarily sour taste receptors, so normally things that would taste very sour or tart, somehow begin to taste very sweet.
To je glikoprotein miraculin, prirodna tvar. Još uvijek me izbezumi svaki put kad ga jedem, ali ima jedinstvenu sposobnost da maskira određene recptore okusa na vašem jeziku, tako da na receptorima za kiselo stvari koje bi imale kiseo ili trpak okus nekako dobivaju vrlo sladak okus.
