Glycine

Glycine(muchidimbu Gly), inozivikanwawo se acetic acid, i amino acid isingakoshi, fomura yayo yemakemikari iC2H5NO2. Glycine i amino acid ye endogenous antioxidant yakaderedzwa glutathione, iyo inowanzowedzerwa nezvinobva kunze kana muviri uri pasi pekushushikana kwakanyanya, uye dzimwe nguva inonzi semi-essential amino acid. Glycine ndeimwe yema amino acids ari nyore.

Hunhu hwemakemikari:

Kristaro chena che monoclinic kana hexagonal, kana upfu hwe crystalline chena. Hainhuwi, ine kuravira kwakanaka. Inonyungudika nyore mumvura, inonyungudika mumvura: 25g/100ml pa25℃; Pa50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml pa75℃; Pa100℃, i67.2g/100ml. Hainyungudike zvakanyanya muethanol, inenge 0.06g yakanyungudika mu100g anhydrous ethanol. Hainyungudike zvakanyanya muacetone ne ether.

Nzira yekugadzira:

Nzira yeStrecker uye nzira ye chloro-acetic acid ammonification ndiyo nzira huru dzekugadzirira.

Nzira yeStrecker:formaldehyde, sodium cyanide, ammonium chloride reaction pamwe chete, wobva wawedzera glacial acetic acid, mvura yemethylene aminoacetonitrile; Amino acetonitrile sulfate yakawanikwa nekuwedzera methylene acetonitrile kuethanol kana paine sulfuric acid. Sulfate inoora nebarium hydroxide kuti iwane glycine barium salt; Zvadaro sulfuric acid inowedzerwa kuti iite barium, iisefe, iwedzere filtrate, uye mushure mekutonhodza inogadzira glycine crystals. Kuedza [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Nzira yekubvisa chloro-acetic acid ammoniation:Mvura yeammonia neammonium bicarbonate yakasanganiswa ichipisa kusvika 55℃, zvichiwedzera chloro-acetic acid aqueous solution, reaction kwemaawa maviri, wozodziisa kusvika 80℃ kubvisa residual ammonia, decolorization ne activated carbon, filtration. Mhinduro ye decolorizing yakawedzerwa ne 95% ethanol kuti glycine iite crystallize, isefe, isuke ne ethanol uye iomeswe kuti chigadzirwa chisina kuchena chibudiswe. Nyungudutsa mumvura inopisa wozoisanganisa zvakare ne ethanol kuti glycine iwane glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Pamusoro pezvo, glycine inotorwawo kubva mu hydrolyzate yesiriki uye inonyungudutswa ne gelatin sezvinhu zvisina kugadzirwa.

Kushandiswa:

Munda wezvekudya

1, inoshandiswa semakemikari ekugadzirisa zvinhu, inogonawo kushandiswa mukurapa, chikafu uye zvekudya, indasitiri yefetereza yenitrogen inoshandiswa semushonga wekubvisa kabhoni usina chepfu;

2, inoshandiswa sekuwedzera kwezvekudya, inonyanya kushandiswa pakugadzira zvinwiwa nezvimwe zvinhu;

3, ine simba rekudzivirira kubereka kwe subtilis neEscherichia coli, saka inogona kushandiswa semushonga wekuchengetedza zvigadzirwa zve surimi, peanut butter, nezvimwewo, kuwedzera 1% ~ 2%;

4, ine simba rekudzivirira muviri (ichishandisa simbi chelate pamwe chete), yakawedzerwa kukirimu, chizi, margarine inogona kuwedzera hupenyu hwekuchengetera hwe3 ~ 4 kanomwe;

5. Kuti mafuta agare zvakanaka muzvingwa zvakabikwa, glucose 2.5% uye glycine 0.5% zvinogona kuwedzerwa;

6. Wedzera 0.1% ~ 0.5% muupfu hwegorosi kuti ubike manoodles nekukurumidza, ayo anogona kuita basa rekurunga panguva imwe chete;

7, kuravira kwemunyu nevhiniga kunogona kuita basa rekuchengetedza, huwandu hwezvinhu zvakawedzerwa munyu 0.3% ~ 0.7%, zvigadzirwa zveasidhi 0.05% ~ 0.5%;

8, zvichienderana nemitemo yedu yeGB2760-96 inogona kushandiswa sezvinonhuwira.

Munda wekurima

1. Inonyanya kushandiswa sechinhu chinowedzera uye chinokwezva kuwedzera maamino acids muchikafu chehuku, zvipfuyo, kunyanya mhuka dzinovaraidza. Inoshandiswa sechinhu chinowedzera mapuroteni akasanganiswa nemvura, sechinhu chinobatanidza mapuroteni akasanganiswa nemvura;

2, mukugadzirwa kwemishonga yezvipembenene inoshandiswa mukugadzirwa kwemishonga yezvipembenene inonzi pyrethroid intermediate glycine ethyl ester hydrochloride, inogonawo kugadzirwa ne fungicide isobiurea uye herbicide solid glyphosate.

Munda wemaindasitiri

1, inoshandiswa sechinowedzera mhinduro yekuputira;

2, inoshandiswa muindasitiri yemishonga, bvunzo dzemakemikari uye kugadzirwa kwezvinhu zvakasikwa;

3, inoshandiswa se cephalosporin mbishi, sulfoxamycin yepakati, imidazolacetic acid synthesis yepakati, nezvimwewo;

4, inoshandiswa sezvinhu zvekushongedza.

Chigadzirwa Packaging: 25kg / bhegi

Kuchengetera kunofanira kunge kuri panzvimbo inotonhorera, yakaoma uye inofefetedza mweya.
