txhawm rau khaws cov khoom noj tshiab, feem coob ntawm cov neeg tsim khoom siv txhua yam khoom noj khoom haus ntxiv - preservatives. Ib qho ntawm cov tshuaj ntxiv yog E282. Yog tsis muaj nws, kev txuag rau lub caij ntuj no tsis tiav. Cov khoom no yog dab tsi? Puas muaj kev phom sij rau tib neeg lub cev?

Kev piav qhia

Calcium propionate (Calcium Propionate), preservative E282 yog cov khoom noj khoom haus ntxiv, cov khoom siv tsis zoo, cov ntsiab lus ntawm calcium ntsev thiab propionic acid. Nws muaj daim ntawv ntawm cov xim tsis muaj xim crystalline hmoov lossis granules, tsis muaj ntxhiab tsw. Cov zaub mov no tau txais los ntawm reacting propionic acid nrog calcium chloride thiab lwm yam Ca-muaj tshuaj.

Calcium propionate: formula, tshuaj muaj zog

E282 muaj cov tshuaj formula - C6H10O4Ca. Lub derivative ntawm no additive yog propionic acid E280 (tseem hu ua propanoic los yog methyl acetic acid) - cov khoom noj preservative nyob rau hauv nws cov ntshiab daim ntawv, corrosive kua nrog ib tug heev pungent tsw. Cov khoom ntawm E282 yog vim qhov kev ua ntawm propionic acid. Qhov noacid yooj yim reacts nrog tej yam tshuaj thiab tsim tshuaj compounds (amides, acid halides, esters, thiab lwm yam), dissolves nyob rau hauv tej organic solvents, nrog rau cov dej. Propionic acid yog indispensable nyob rau hauv cov zaub mov thiab kev ua liaj ua teb industries, nyob rau hauv zus tau tej cov tshuaj pleev ib ce, kuab tshuaj thiab surfactants.
