Lub caij ntuj sov tau los txog, thiab qhov tsis meej pem tshaj plaws rau txhua tus yog kev khaws cia zaub mov. Yuav ua li cas kom paub tseeb tias cov zaub mov tshiab tau dhau los ua ib qho lus nug kub niaj hnub no. Yog li peb yuav tsum khaws cov txiv hmab txiv ntoo thiab zaub tshiab li cas thaum lub caij ntuj sov kub heev? Hauv qhov xwm txheej no, nyob rau xyoo tas los no, kev tshawb fawb tau pom ib qho tshuaj tiv thaiv ethylene -1-MCP zoo. 1-MCP inhibitor tsis yog tsuas yog tsis muaj tshuaj lom, tsis muaj teeb meem, tsis muaj cov khoom seem, thiab zoo rau ib puag ncig, tab sis kuj siv dav rau kev khaws cia txiv hmab txiv ntoo, zaub, thiab paj. Hauv qab no, peb yuav qhia cov ntsiab lus tshwj xeeb ntawm cov khoom 1-MCP.
1-MCP yog dab tsi?
1-MCP, tseem hu ua 1-Methylcycloprotene,CAS 3100-04-7. 1-MCP yog ib qho tshuaj ethylene inhibitor zoo uas tuaj yeem tiv thaiv ntau yam kev hloov pauv ntawm lub cev thiab biochemical uas cuam tshuam nrog kev siav ntawm txiv hmab txiv ntoo los ntawm ethylene, tiv thaiv kev ua pa ntawm cov nroj tsuag, ua kom qeeb qeeb kev siav thiab kev laus ntawm txiv hmab txiv ntoo, tswj cov tsos qub thiab qhov zoo ntawm txiv hmab txiv ntoo thiab zaub ntev, txo cov dej evaporation, txo cov kab mob puas tsuaj thiab cov kab mob me me, Txhawm rau tswj cov txiv hmab txiv ntoo kom zoo. Thiab 1-MCP tsis muaj tshuaj lom thiab tsis muaj cov khoom seem, ua tau raws li ntau yam cim ntawm cov tshuaj preservatives hauv tebchaws, thiab tuaj yeem siv nrog kev ntseeg siab.

Daim ntawv thov 1-MCP
Ua ntej siv 1-MCP, feem ntau txoj kev khaws cia thiab khaws cia tau siv: 1. txias txias, 2. tswj huab cua, thiab 3. kho cua sov, lub teeb, thiab microwave. Txawm li cas los xij, peb txoj kev no xav tau ntau tus neeg ua haujlwm thiab cov peev txheej, thiab lub sijhawm ntev thiab luv. Kev tshawb fawb tau qhia tias 1-MCP tuaj yeem sib tw zoo los khi rau cov ethylene receptors, ncua cov txiv hmab txiv ntoo siav thiab laus. Vim nws cov khoom tsis muaj tshuaj lom, siv tsawg, ua haujlwm tau zoo, thiab cov khoom siv tshuaj ruaj khov, tam sim no nws siv dav hauv kev khaws cia txiv hmab txiv ntoo thiab zaub, nrog kev siv lag luam siab thiab tus nqi txhawb nqa.
1-MCP tsis yog tsuas yog tiv thaiv lossis ncua qhov tshwm sim ntawm kev laus ntawm cov nroj tsuag xwb, tab sis kuj muaj kev lom tsawg. LD50> 5000mg / kg yog qhov tseeb tsis muaj tshuaj lom; Qhov concentration siv yog qis heev, thiab thaum ua cov txiv hmab txiv ntoo, zaub, thiab paj, qhov concentration hauv huab cua tsuas yog xav tau ib lab, yog li cov nyiaj seem hauv cov txiv hmab txiv ntoo, zaub, thiab paj tom qab siv yog qis heev uas nws tsis tuaj yeem pom; 1-MCP kuj tau dhau qhov kev tshuaj xyuas ntawm US Environmental Protection Agency (EPA lub vev xaib tshaj tawm) thiab suav tias muaj kev nyab xeeb thiab tsis muaj tshuaj lom, tsim nyog rau kev siv hauv 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 cov kev txwv kev noj tshuaj thaum siv.
Kev kwv yees ua lag luam rau 1-MCP yog dab tsi?
Rau cov teb chaws ua liaj ua teb, muaj ntau cov txiv hmab txiv ntoo thiab zaub tshiab tsim tawm txhua xyoo. Vim yog txoj kev loj hlob tsis zoo ntawm kev thauj khoom txias rau cov khoom ua liaj ua teb, kwv yees li 85% ntawm cov txiv hmab txiv ntoo thiab zaub siv cov khoom thauj ib txwm muaj, ua rau muaj kev puas tsuaj thiab poob ntau heev. Qhov no muab qhov chaw ua lag luam dav dav rau kev txhawb nqa thiab kev siv 1-methylcyclopropene. Cov txiaj ntsig tshawb fawb qhia tau tias 1-methylcyclopropene tuaj yeem txo qhov mos thiab lwj ntawm cov txiv hmab txiv ntoo thiab zaub, thiab txuas ntxiv lawv lub neej txee thiab lub sijhawm khaws cia. Qhov no xaus qhov kev qhia txog1-MCPYog tias koj xav paub ntxiv txog cov khoom, thov tawm lus rau kuv.
