Cov yam ntxwv ntawm sodium diacetate thiab nws cov tshuaj tiv thaiv kab mob

Sodium diacetate, tseem hu ua sodium diacetate, yog cov tshuaj siv tau ntau yam, feem ntau yog siv los ua cov tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tsw qab, PH regulators, thiab nqaij hauv cov khoom noj thiab kev lag luam. Cov khoom khaws cia, thiab lwm yam, kuj yog cov khoom siv tseem ceeb ntawm cov tshuaj tiv thaiv kab mob.

Lub cev thiab tshuaj muaj zog

Sodium diacetate yog abbreviated li SDA, dawb crystalline mov hmoov nrog anhydrous molecular hnyav ntawm 142.9, tsw ntawm acetic acid, yooj yim nqus dej noo, yooj yim soluble nyob rau hauv dej thiab cawv, siv lead ua qauv yog tsis tu ncua hexahedron, melting point yog 96 ℃ -97 ℃, Nws yuav decompose thaum rhuab mus rau saum 150 ℃.

lub ntsiab feature

a) Cov tshuaj tiv thaiv kab mob thiab tiv thaiv corrosion yog zoo dua li ntawm benzoates, thiab cov koob tshuaj dav dav yog 0.3-3g / kg.

b) Nws tsis hloov cov yam ntxwv ntawm cov zaub mov thiab tsis cuam tshuam los ntawm pH ntawm cov zaub mov nws tus kheej. Nws koom nrog hauv cov metabolism hauv tib neeg lub cev thiab tsim CO2 thiab H2O, uas tuaj yeem suav tias yog ib feem ntawm cov khoom noj, tswj cov xim qub, ntxhiab thiab cov ntsiab lus ntawm cov khoom noj.

c) Nws muaj ntau yam kev siv thiab siv los tiv thaiv mildew thiab tshuaj tua kab mob ntawm txhua yam khoom noj, thiab tseem muaj kev siv zoo hauv tshuaj, luam yeeb, papermaking, fruit preservation, feed and other industries.

d) Kev ua haujlwm yooj yim thiab hloov tau yooj yim, tuaj yeem ntxiv ncaj qha, txau lossis dipped

e) Cov qaub saj yog mos, uas overcomes pungent tsw ntawm propionate

nyhuv

Cov kev tshawb fawb tau pom tias sodium diacetate feem ntau cuam tshuam nrog kev sib cuam tshuam ntawm cov enzymes los ntawm kev nkag mus rau hauv lub cell phab ntsa ntawm cov pwm, inhibiting cov pwm tsim, yog li ua tiav cov hauj lwm zoo los tiv thaiv pwm thiab tshuaj tua kab mob. Sodium diacetate zoo rau Aspergillus niger, Rhizopus niger, inhibitory nyhuv ntawm Aspergillus flavus thiab Trichoderma viride yog zoo dua li poov tshuaj sorbate.

1 Ntxiv 0.1-0.2% 1-2 kg / tuj SDA pub tuaj yeem tiv thaiv kab mob mildew thiab ncua sij hawm cia ntawm pub rau 1-2 lub hlis; ntxiv 0.1-0.3% SDA rau kev sib xyaw pub tuaj yeem ua rau cov tshuaj tua kab mob thiab tshiab. 3-5 lub hlis.

2. Raws li cov khoom noj khoom haus tsw qab

Ntxiv 0.05-0.2% SDA rau pellet compound pub tuaj yeem ua rau cov protein siv hauv kev pub noj los ntawm 11%, ntses hnyav nce ntau dua 10%, thiab piglet hnyav nce los ntawm 6-8%. Nws tuaj yeem muab ntxiv rau cov mis nyuj sib xyaw pub rau hauv qhov tsim nyog. Ua kom cov mis nyuj muaj protein ntau ntawm cov mis nyuj.

3. Ua tshuaj tua kab mob

Ntxiv 0.1-0.2% SDA rau cov khoom noj hauv dej tuaj yeem tiv thaiv cov kab mob ntses los ntawm homologous microorganisms, thiab tuaj yeem siv ua lub pas ntses kom paub meej thiab tshuaj tua kab mob; Ntxiv 0.05-0.3% SDA rau nqaij qaib pub tuaj yeem tiv thaiv qaib rub plab, thiab ua rau kom muaj sia nyob ntawm lub sijhawm brooding ntau dua 10%.

4. Daim ntawv thov ntawm sodium diacetate nyob rau hauv pub rau weaning piglets

Qhov sib ntxiv ntawm 0.3% sodium diacetate nyob rau hauv pub tau nce txhua hnub ntawm weaned piglets los ntawm 10.8% piv nrog tsis muaj ntxiv. Qhov txawv yog qhov tseem ceeb; nws muaj kev cuam tshuam loj heev rau kev noj zaub mov txhua hnub ntawm cov piglets uas tsis muaj menyuam. Qhov sib ntxiv ntawm sodium diacetate tuaj yeem ua rau muaj txiaj ntsig zoo rau kev hloov pauv hloov pauv ntawm cov piglets weaned (nce 10.5%). Nws yuav yog tias sodium diacetate txhim kho kev siv cov khoom noj nitrogen thiab lub zog.
