I-fumaric acid
I-fumaric acid, njengesongezo lokutya, isetyenziswa njengomlawuli we-Acidity kwaye ichazwa yinombolo ye-E297. I-faumaric acid yi-aciddulent yokutya esetyenzisiweyo ukusukela ngo-1946. Isetyenziswa iziselo ezinesiselo kunye nokubhaka iipowda ezikhoyo kwiimfuno ezibekwe kubunyulu. Isetyenziswa ngokubanzi njengendawo yokuhlala ye-tartaric acid kwaye ngamanye amaxesha endaweni ye-cicric acid, ngenqanaba le-1.36 g le-cicric acid yokongeza ubuncinane, ngokufana nendlela esetyenziswa ngayo. Ikwasetyenziswa njenge-gogulnt kwimixokelelwane yestoup.
