Nyob rau hauv ntau cov khoom uas peb noj txhua hnub, muaj ib qho E 200 ntxiv, thiab ob peb paub tias nws yog dab tsi. Hauv tsab ntawv no, nws yuav yog hais txog E200 thiab nws cov nyhuv ntawm tib neeg lub cev.
Kev piav qhia thiab cov yam ntxwv ntawm cov khoom noj khoom haus additive E200
Sorbic acid (E200) yog ib hom tshuaj tsis muaj xim uas ua haujlwm nyob rau hauv qhov kev txiav txim ntawm dej, uas yog ib qho organic compound. Vim yog lub peev xwm los tiv thaiv cov tsos ntawm cov pwm ntawm cov khoom thiab mus cuag lawv cov txee lub neej, qhov no cov kab mob hauv cov khoom noj khoom haus zoo siv.
Rau thawj lub sij hawm, acid acid thaum lub sij hawm distillation ntawm rowan roj muaj antimicrobial thaj, uas tau clarified nyob rau hauv lub xeem tiam, nyob rau hauv thawj ib nrab. Nws tau siv los ua ib lub khoom txuag thiab tsim tawm ntawm ib qho kev lag luam hauv nruab nrab thaum xyoo 1950.
Cov khoom ntawm E200 khoom noj khoom haus
Cov khoom ntawm sorbic acid yog piav qhia los ntawm nws muaj pes tsawg leeg. Txoj kev loj hlob ntawm cov kab mob uas yuav tsim kev puas tsuaj rau kev noj qab haus huv, nrog rau cov pwm, poov xab ntsev, cov tshuaj ntxiv no tiv thaiv vim cov kab mob antimicrobial. Nyob rau hauv lub chav kawm ntawm kev tshawb fawb thiab ntau experiments, carcinogenic tshuaj tsis tau kuaj nyob rau hauv nws. Sorbic acid E200, tau nkag mus rau hauv tib neeg lub cev raws li qhov tsim nyog txwv, haum nws muaj feem xyuam rau nws, namely nws ntxiv zog rau lub cev, neutralizes ntau yam tshuaj lom. Nws tau raug tsim tawm tias nws yog dhau ntawm lub hwj chim los ua puas microbes tag nrho rau ib qho preservative, nws tsuas yog tiv thaiv lawv los ntawm kev tsim, yog li nws yog zoo dua mus ntxiv rau raw cov ntaub ntawv uas lawv tsis muaj.
Nyob rau hauv kev sib ntaus tawm tsam microbes sorbic acid E200 yog tsuas yog siv tau yog hais tias lub acidity yog hauv pH 6.5. Qhov no acid yog chemically ruaj, tab sis nws muaj peev xwm tau yooj yim evaporate nrog dej.
Daim ntawv thov ntawm E200 tsom
Nyob rau hauv cov zaub mov, sorbic acid ntxiv rau ntau yam, tab sis nws qhov nqi nruab nrab ntawm 100 kg ntawm cov khoom tiav yog 30-300 g. Lub preservative ntxiv rau ntau yam khoom . Tso cai rau siv cov sorbic acid hauv kev lag luam khoom noj ntau tshaj li kaum tus qauv. Nws yog ntxiv ib tus zuj zus, thiab yog ib feem ntawm lwm cov tshuaj tivthaiv. Sorbic acid E 200, raws li cov specifications thiab GOSTs, yog ib feem ntawm cheese thiab bakery khoom, mayonnaise, ntau hom zaub mov kaus poom thiab pates, khoom qab zib (khoom qab zib, jams, jams), dej haus (dej qab zib, kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo) thiab lwm yam khoom. Thaum lub sij hawm npaj ntawm qhov kev xeem, acid dissolution xyaum tsis tshwm sim, yog li kev loj hlob ntawm poov yog nqa tawm raws li kev xav. Nws txoj kev pov thaiv kev ua haujlwm nws pom tias twb ua tiav lawm.
Lub txee lub neej ntawm cov dej haus los ntawm kev ntxiv ntawm E 200 yog nce los ntawm 30 hnub lossis ntau dua. Vim tias qhov kub tsis tshua muaj nyob hauv dej cov khoom txuag tsis zoo, thiaj li ua kom qhov kev lag luam no tsis muaj dej caw, nws zoo dua yog siv cov kua tshuaj sodium sorbate es tsis txhob siv cov kua qaub. Sorbic acid, ntxiv rau txoj kev lag luam, yog siv
Ua kom mob ntxiv E 200
Hauv cov ntawv tso cai, uas yog 25 mg / kg, ntxiv E 200 raug mob rau tib neeg lub cev yuav tsis ua rau. Txawm li cas los xij, thaum nws siv rau ntawm daim tawv nqaij, kev fab tshuaj tsis haum yog ua tau, tshwm sim ua rau khaus thiab ua pob. Txoj kev raug mob rau tib neeg lub cev yog tias nws txav cyanocobalamin ( vitamin B12 ). Vim hais tias nws tsis muaj nyob rau hauv lub cev, paj hlwb pib tuag, vim li ntawd, muaj ntau yam txog kev puas hlwb. Australia yog tib lub tebchaws hauv ntiaj teb uas txwv tsis pub siv cov khoom noj ntxiv E 200.
