Kev Siv Cinnamic Acid hauv Khoom Noj
cinnamic acid yog dab tsi?
Cinnamic acid, tseem hu ua -phenylacrylic acid, 3-phenyl-2-acrylic acid, yog ib yam ntawm cov organic teeb meem, tshuaj formula C9H8O2, yog ib tug organic acid cais los ntawm cinnamon bark los yog benzoin. Phenylacrylic acid ua los ntawm deamination thiab degradation ntawm phenylalanine nyob rau hauv cov nroj tsuag. Mas siv nyob rau hauv tsw, khoom noj khoom haus additives, kws lag luam, kev zoo nkauj, tshuaj tua kab, organic synthesis thiab lwm yam.
Cinnamic acid tuaj yeem dhau los ua cov tshuaj tiv thaiv corrosive rau cov tshuaj yej dej qab zib uas tsis muaj tshuaj lom
Tshuaj yej polyphenols muaj zog antioxidant nyhuv thiab muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv. Tshuaj yej polyphenol yog cov khoom noj khoom haus tseem ceeb ntawm cov tshuaj yej haus, thiab nws kuj yog ib qho tseem ceeb ntsuas ntsuas qhov zoo ntawm cov tshuaj yej haus. Txhawm rau kom tsis txhob txo cov ntsiab lus ntawm cov tshuaj yej polyphenols hauv cov tshuaj yej dej qab zib, ua kom cov tshuaj yej dej qab zib zoo, thiab yooj yim khaws cov khoom, ntau tus kws paub txog zaub mov muaj txiaj ntsig tau tshawb fawb. Cov kws tshaj lij PA Anslow thiab M. Stratford ntawm Rotterdam, Netherlands lub tuam txhab Unifil tau pom ib qho kev tsim ua ntej. Kev khaws cia ntawm cov tshuaj yej haus yuav tsum yog nyob ntawm kev tsim cov tshuaj tiv thaiv corrosion. Txawm li cas los xij, xyoo 2006, lub zej zog kev noj qab haus huv hauv tebchaws Askiv tau tshaj tawm rau lub ntiaj teb tias benzoic acid, sorbic acid preservatives yog ib qho yooj yim rau cov tshuaj tiv thaiv antioxidants los tsim cov carcinogens, thiab qhov zoo thiab khaws cia ntawm cov tshuaj yej haus tau dhau los ua qhov nyuaj rau kev sib haum xeeb. Txawv teb chaws, ntau lub teb chaws tau txwv tsis pub ntxiv benzoic acid, sorbic acid thiab lwm yam tshuaj tua kab mob hauv cov dej tshuaj yej. Tuam Tshoj tus qauv kev tu cev rau kev siv cov khoom noj khoom haus kuj tseem qhia meej tias cov tshuaj tua kab mob benzoic acid thiab sorbic acid tsis raug tso cai ntxiv rau cov dej haus tshuaj yej.
Lub tuam txhab rotterdam-based invention muaj xws li tshuaj yej extracts, ib tug antimicrobial active npaum li cas ntawm cinnamic acid los yog nws acidic derivatives, thiab ib tug sourness tus neeg sawv cev uas ua rau cov dej qab zib pH qis dua 4.5. Qhov zoo tshaj plaws ntawm qhov kev tsim no yog tias nws tuaj yeem siv los npaj cov tshuaj yej ruaj khov ntawm chav tsev kub thiab haum rau cov kaus poom txias. Nyob rau tib lub sijhawm, vim nws siv cov tshuaj tua kab mob tsis yog benzoic acid, sorbic acid, thiab cinnamic acid nws tus kheej rau cov txuj lom, kiag li tsis muaj tshuaj lom rau tib neeg lub cev.
Daim ntawv thov ntawm cinnamic acid nyob rau hauv cov khoom noj - cinnamic aldehyde yog thawj xaiv rau txiv hmab txiv ntoo preservative
Tuam Tshoj yog ib lub teb chaws cov txiv hmab txiv ntoo loj nyob rau hauv lub ntiaj teb no, nrog tag nrho cov zis ntawm 120 lab tons nyob rau hauv 2010. Txij li thaum 1993, Tuam Tshoj cov txiv hmab txiv ntoo tawm tau nyob rau hauv lub ntiaj teb no, thiab tau ua lub ntiaj teb thawj cov txiv hmab txiv ntoo tsim rau 18 xyoo sib law liag. Vim yog perishability ntawm txiv hmab txiv ntoo thiab nws raws caij nyoog thiab lub regional ntau lawm, txiv hmab txiv ntoo preservation yog ib qho tseem ceeb heev nyob rau hauv Tuam Tshoj. Qhov nrov thiab nrov ntawm kev ua haujlwm siab, qis-tshuaj lom tshuaj tiv thaiv thiab nws daim ntawv thov thev naus laus zis tuaj yeem tsim lub hauv paus zoo rau cov txiv hmab txiv ntoo raws caij nyoog, kev muag khoom txhua xyoo, cov qoob loo siab thiab cov qoob loo zoo, txo qhov siab ntawm kev lag luam hauv nruab nrab, txo qis thiab txhawb kev ncig. . Muaj ntau tshaj 20 hom tshuaj tua kab mob siv rau hauv cov txiv hmab txiv ntoo khaws cia thiab kev thauj mus los hauv Suav teb, xws li carbendazim, thiobacillazim, methyl thiobacillazim, benzimazim, imazole, sec-butylamine, isometalourea, sulfur dioxide, thiab lwm yam., tab sis cov preservatives no muaj qee qhov teeb meem, xws li raws li tus nqi siab, residual toxicity los yog cov nyhuv tsis zoo. Yog li ntawd, cov neeg siab dub ua txhaum txoj cai lij choj hauv lub tebchaws, siv cov txiv hmab txiv ntoo xws li txiv apples, txiv kab ntxwv thiab txiv kab ntxwv rau waxing thiab anticorrosion. Tab sis txawm hais tias qhov no tuaj yeem ua kom ntev lub sijhawm khaws cia, ua kom zoo nkauj, tab sis yooj yim ua rau "zoo sab nraud rotten hauv", vim tias paraffin yog airtight, yooj yim ua rau cov cua sov thiab cov pa phem sab hauv tuaj yeem tawm tsis tau, tsim cov anaerobic lwj.
Yog li ntawd, nws tsis yog tsuas yog ib qho tseem ceeb thiab ceev kom nrhiav tau cov tshuaj toxicity tsawg, muaj kev nyab xeeb, zoo, yooj yim rau siv thiab pheej yig txiv hmab txiv ntoo preservative. Rau qhov no, sab qab teb Tuam Tshoj Agricultural university cuam tshuam nrog pab pawg kws tshaj lij tau ua haujlwm nyuaj. Pab neeg mus rau 90 hom cog cov roj tseem ceeb tau siv los ua cov khoom siv, nrog rau kev ua haujlwm fumigation ntawm apricot txiv hmab txiv ntoo thiab kiwi txiv hmab txiv ntoo preservation lub luag hauj lwm los ua ib tug ntau ntawm kev sib piv txoj kev tshawb no, cov txiaj ntsig tshuaj ntsuam rau bacteriostasis muaj zog daj ntseg cinnamon tseem ceeb roj, cinnamaldehyde, roob tub tseem ceeb roj. , geranium thiab nplooj nplooj roj thiab lwm yam 11 hom nroj tsuag tseem ceeb roj, suav nrog cinnamaldehyde raus siv thiab siv fumigation kev kho mob ntawm citrus penicilliosis ua haujlwm zoo tshaj plaws. Cov txiaj ntsig tau pom tias cinnamaldehyde tsis tuaj yeem ua tiav cov nyhuv tshuaj tua kab mob zoo dua los ntawm soaking citrus thiab strawberry ib leeg, tab sis cinnamaldehyde tuaj yeem ua tiav cov nyhuv antiseptic zoo dua los ntawm fumigation ib leeg. Tsis tas li ntawd, cinnamaldehyde ua ke nrog chitosan txheej tuaj yeem ua tiav cov nyhuv anticorrosion zoo dua ntawm cov txiv hmab txiv ntoo. Cinnamaldehyde muaj toxicity tsawg, qhov zoo ntawm kev nyab xeeb, tsis tshua muaj nqi thiab tsw ntxhiab tsw, raws li ib yam ntawm cov khoom muaj txiaj ntsig zoo, "tus qauv ntawm lub teb chaws zaub mov kev nyab xeeb cov qauv ntawm kev siv cov khoom noj additives GB27602011 version ntawm lwm cov txiv hmab txiv ntoo los tiv thaiv corrosive antistaling tus neeg saib xyuas nruj ntawm cov txwv tsis pub, ntawm cinnamaldehyde nyuam qhuav hais tias "raws li qhov yuav tsum tau los tsim ib tug me me npaum li cas ntawm kev siv", uas yog tsis muaj kev txwv. Nyob rau hauv view ntawm cov saum toj no zoo ntawm cinnamaldehyde, ua ke nrog nws saj zawg zog thov txoj kev xws li txiv hmab txiv ntoo immersion, fumigation thiab tshuaj tsuag ua ntej. Kev xaiv, cov kws tshaj lij tau lees paub tias cinnamaldehyde xav tias yuav dhau los ua cov txiv hmab txiv ntoo ntau tshaj plaws thiab cov khoom noj tshiab.
