Kev Ntsuas Tshuaj Propionic Acid Hauv Kev Lag Luam
1. Scope ntawm Daim Ntawv Thov
Txoj kev no siv tau rau kev txiav txim siab ntawm propionic acid hauv cov ncuav mog qab zib, ncuav mog qab zib hli, cov khoom lag luam taum pauv tsis tau fermented, thiab vinegar, nrog rau qhov txwv ntawm 0.10 g / kg.
2. Kev Npaj Cov Kev Daws Teeb Meem Txheem
Kev daws teeb meem txheem
Muab 100 mg ntawm tus qauv ntsuas rau hauv lub raj mis 10 mL volumetric, yaj nrog dej, thiab dilute kom txog thaum nws muaj qhov concentration ntawm 10 mg/mL.
Kev daws teeb meem nruab nrab
Siv lub raj xa dej kom raug, muab 1 mL ntawm 10 mg/mL cov kua txheem rau hauv lub raj mis 10 mL volumetric, dilute nrog dej kom txog thaum nws cim, thiab sib tov kom zoo kom tau qhov concentration ntawm 1.0 mg/mL.
