Txawm li cas los xij, muaj qhov sib txawv ntawm ob qho no. Dr. Joanna Buckley, tus thawj coj kev kawm ntawm Royal Society of Chemistry, tau hais tias: "Citric acid thiab vinegar yog ob qho tib si cov khoom xyaw nquag hauv ntau cov tshuaj ntxuav hauv tsev, thiab ob qho tib si ua haujlwm tau zoo. Vinegar muaj pH ntawm 2 thiab 3, ua rau nws yog cov kua qaub muaj zog - qhov pH qis dua, nws muaj kua qaub ntau dua. Citric acid (xws li cov uas pom hauv cov txiv hmab txiv ntoo citrus) muaj pH siab dua me ntsis, yog li nws muaj kua qaub tsawg dua me ntsis. Yog li ntawd, nws muaj kev pheej hmoo qis dua me ntsis ntawm kev ua puas tsuaj rau cov chaw mos mos, thiab muaj qhov ntxiv ntawm kev tawm hauv koj lub tsev tsw qab tshiab, es tsis zoo li lub khw muag ntses thiab chips!"

Tshem lub lauj kaub dej, ua tib zoo ntxiv 2 diav ntawm citric acid rau hauv qhov sib tov thiab cia nws ua haujlwm rau 15-20 feeb (nco ntsoov sau ib daim ntawv kom tsis txhob muaj leej twg siv nws thaum lub sijhawm no!).
