Lub caij ntuj sov tau los txog, thiab qhov tsis meej pem tshaj plaws rau txhua tus yog kev khaws cov zaub mov. Yuav ua li cas kom paub tseeb tias cov khoom noj tshiab tau dhau los ua lub ntsiab lus kub niaj hnub no. Yog li cas peb yuav tsum khaws cov txiv hmab txiv ntoo thiab zaub tshiab rau lub caij ntuj sov? Nyob rau hauv lub ntsej muag ntawm qhov teeb meem no, nyob rau hauv xyoo tas los no, kev tshawb fawb kev tshawb fawb tau pom ib tug zoo inhibitor ntawm ethylene kev txiav txim -1-MCP. 1-MCP inhibitor tsis yog tsuas yog tsis muaj tshuaj lom, tsis muaj mob, tsis muaj residue, thiab ib puag ncig tus phooj ywg, tab sis kuj siv dav rau kev khaws cov txiv hmab txiv ntoo, zaub, thiab paj. Hauv qab no, peb yuav qhia cov ntsiab lus tshwj xeeb ntawm 1-MCP cov khoom.
1-MCP yog dab tsi?
1- MCP, tseem hu ua 1-Methylcycloprotene,CAS Nr .: 3100-04-7. 1-MCP yog ib qho zoo ethylene inhibitor uas muaj peev xwm inhibit ib tug series ntawm physiological thiab biochemical cov tshuaj tiv thaiv muaj feem xyuam rau cov txiv hmab txiv ntoo ripening induced los ntawm ethylene, inhibit tsob nroj respiration siv, zoo ncua cov txiv hmab txiv ntoo ripening thiab aging kev vam meej, tuav lub qub tsos thiab zoo ntawm txiv hmab txiv ntoo thiab zaub. ib lub sij hawm ntev, txo cov dej evaporation, alleviate pathological puas thiab microbial lwj, kom khaws cia zoo ntawm cov txiv hmab txiv ntoo. Thiab 1-MCP yog tsis muaj tshuaj lom thiab tsis muaj residue, ua tau raws li ntau yam kev ntsuas ntawm lub teb chaws video preservatives, thiab siv tau nrog kev ntseeg siab.

1-MCP daim ntawv thov
Ua ntej daim ntawv thov ntawm 1-MCP, feem ntau ntawm kev txuag lub cev thiab kev khaws cia tau txais kev pom zoo: 1. kev siv cov tub yees txias, 2. tswj qhov chaw cia, thiab 3. kev kho cua sov, lub teeb, thiab microwave. Txawm li cas los xij, peb txoj kev no yuav tsum muaj ntau tus neeg ua haujlwm thiab cov peev txheej, thiab lub sijhawm ntev thiab luv. Kev tshawb fawb tau pom tias 1-MCP tuaj yeem sib tw tau zoo los khi rau ethylene receptors, ncua cov txiv hmab txiv ntoo ripening thiab kev laus. Vim nws cov khoom tsis muaj tshuaj lom, kev siv tsawg, kev ua haujlwm siab, thiab cov khoom siv tshuaj ruaj khov, tam sim no tau siv dav hauv kev khaws cov txiv hmab txiv ntoo thiab zaub, nrog rau kev lag luam siab thiab kev nce qib.
1-MCP tsis tsuas yog inhibits lossis ncua qhov tshwm sim ntawm kev laus ntawm lub cev hauv cov nroj tsuag, tab sis kuj muaj toxicity tsawg. LD50> 5000mg / kg yog qhov tsis muaj tshuaj lom; Cov concentration siv yog tsawg heev, thiab thaum ua cov txiv hmab txiv ntoo, zaub, thiab paj, cov concentration nyob rau hauv cov huab cua tsuas yog yuav tsum tau ib lab, yog li cov seem nyob rau hauv txiv hmab txiv ntoo, zaub, thiab paj tom qab siv yog tsawg heev uas nws tsis tuaj yeem kuaj pom. ; 1-MCP kuj tau dhau qhov kev tshuaj xyuas ntawm US Environmental Protection Agency (EPA lub vev xaib tshaj tawm) thiab pom tias muaj kev nyab xeeb thiab tsis muaj tshuaj lom, haum rau siv paj thiab txiv hmab txiv ntoo thiab zaub, thiab muaj kev nyab xeeb rau tib neeg, tsiaj txhu, thiab ib puag ncig. Tsis tas yuav tsim kom muaj kev txwv ntau npaum li cas thaum siv.
Dab tsi yog qhov kev xav ntawm kev ua lag luam rau 1-MCP?
Rau cov teb chaws ua liaj ua teb, ntau cov txiv hmab txiv ntoo thiab zaub tshiab tau tsim txhua xyoo. Vim qhov kev loj hlob tsis zoo ntawm cov saw hlau txias logistics rau cov khoom ua liaj ua teb, li ntawm 85% ntawm cov txiv hmab txiv ntoo thiab zaub siv cov logistics zoo tib yam, ua rau muaj kev puas tsuaj loj thiab poob. Qhov no muab kev lag luam dav dav rau kev nce qib thiab kev siv 1-methylcyclopropene. Cov txiaj ntsig kev tshawb fawb qhia tau tias 1-methylcyclopropene tuaj yeem txo qhov muag muag thiab lwj ntawm txiv hmab txiv ntoo thiab zaub, thiab txuas ntxiv lawv lub neej txee thiab lub sijhawm cia. Qhov no xaus qhov kev taw qhia ntawm1- MCP. Yog tias koj xav paub ntau ntxiv txog cov khoom, thov sau ntawv rau kuv.
