Nyob rau hauv cov nqe lus ntawm kev ua cov txheej txheem, acidity regulators (xws li citric acid) optimize qhov chaw tsim khoom, thiab enzyme npaj (xws li amylase) nce raw khoom siv los ntawm 20-30%, ho txhim kho ntau lawm efficiency. Nrog kev txhim kho kev lag luam, cov khoom noj khoom haus ntuj (xws li natamycin) thiab cov khoom siv ntxiv (xws li probiotics) tau dhau los ua ntau dua, ua rau kev lag luam zaub mov mus rau kev nyab xeeb thiab kev noj qab haus huv.
