Sodium Propionate E281 CAS: 137-40-6

Paub meej

Sodium Propionate (CAS: 137-40-}6) yog cov khoom noj muaj kev nyab xeeb feem ntau yog siv los ua pwm inhibitor thiab preservative. Raws li Suav teb chaws tus qauv GB 25549-2010, nws yog tsim los ntawm neutralization, purification, thiab ziab ntawm propionic acid nrog sodium hydroxide los yog sodium carbonate. Nws tshwm sim li dawb crystals, granules, los yog crystalline hmoov, nrog ib tug faint yam ntxwv tsw (propionic acid tsw). Nws yog hygroscopic nyob rau hauv cov huab cua noo, yooj yim soluble nyob rau hauv dej, thiab me ntsis soluble nyob rau hauv ethanol .As ib tug acid- hom preservative, nws antimicrobial efficiency yog siab dua nyob rau hauv qis pH ib puag ncig. Nws inhibits pwm, aerobic spore-forming kab mob, thiab cov kab mob Gram-negative, thiab tshwj xeeb tshaj yog zoo los tiv thaiv kev tsim cov aflatoxin. Txawm li cas los xij, nws tsis cuam tshuam rau cov poov xab ua haujlwm, ua rau nws haum rau cov khoom siv poov xab zoo li pastries .Functionally, nws extends txee lub neej los ntawm kev tiv thaiv spoilage. Nws yog dav siv nyob rau hauv pastries, taum khoom, cheese, soy sauce, thiab ntub hmoov khoom. Ib GB 2760, qhov siab tshaj plaws kev siv hauv pastries yog 2.5g / kg (raws li propionic acid); rau waxberry canning processing, 3% -5% tov yog siv nrog rau qib siab tshaj plaws ntawm 50g / kg (raws li propionic acid), tab sis yuav tsum tau muab yaug kom huv si ua ntej ua. Nws kuj yog siv los ua cov khoom noj khoom haus thiab ua cov slime inhibitor hauv npias ntau lawm.
