Sorbic acid
Sorbic acid thiab nws cov ntsev ntxhia, cov tshuaj ntsuab sorbate thiab calcium sorbate thiab calcium sorbate thiab cov tshuaj tiv thaiv kab mob los tiv thaiv kev loj hlob ntawm pwm, poov xab thiab fungi. Nyob rau hauv dav dav cov ntsev tau nyiam tshaj cov acid daim ntawv vim tias lawv muaj ntau soluble hauv dej. Qhov kev ua tau zoo tshaj plaws rau cov antimicrobial kev ua si yog hauv qab per 6.5 thiab sorbates feem ntau yog siv nyob rau hauv cov hocus ntawm 0.25% rau 0.10%. Ntxiv cov ntsev ua kom zoo rau cov khoom noj yuav txawm li cas los xij nqa cov zaub mov me me yog li PH yuav tsum tau muab kho kom muaj kev nyab xeeb.
Daim Ntawv Thov:
Nws yog siv rau cov khoom noj, kev kho kom zoo nkauj, kev kho mob cov khoom siv kho mob thiab tshuaj tiv thaiv kev ua lag luam rau luam yeeb. Raws li unsaturated acid, nws tseem siv los ua cob, cov duab uas muaj ntxhiab thiab roj hmab.
