Kev Tshaj Lij Lub Hoobkas Muab Khoom 1-MCP 1-Methylcyclopropene CAS 3100-04-7
1-Methylcyclopropene, luv ua 1-MCP, muaj CAS 3100-04-7. 1-Methylcyclopropene yog ib qho tseem ceeb uas tswj kev loj hlob ntawm cov nroj tsuag. 1-MCP tuaj yeem khi rau cov ethylene receptors thiab muaj lub zog khi muaj zog dua li ethylene. 1-mcp hmoov tuaj yeem ua haujlwm tsis tu ncua rau cov ethylene receptors thiab tiv thaiv kev khi ntawm ethylene rau nws cov receptors. Qhov no tuaj yeem thaiv ntau yam kev cuam tshuam ntawm lub cev thiab biochemical cuam tshuam nrog txiv hmab txiv ntoo siav los ntawm ethylene, ncua cov txheej txheem siav, thiab ua tiav cov txiaj ntsig ntawm kev khaws cia.
Nws muaj lub sijhawm khaws cia ntev. Yog tias 1-MCP tseem muaj nyob hauv ib puag ncig, cov txiv hmab txiv ntoo yuav tsis siav tom qab. Nws muaj kev ua haujlwm siab heev thiab tuaj yeem ua haujlwm ntawm qhov concentration ntawm tsuas yog 1ppm (qhov ib lab) hauv huab cua. Tsis muaj tshuaj lom thiab tsis muaj kuab paug, 1-methylcyclopropene yog cov pa roj volatile tsis muaj tshuaj lom uas tsis tawm cov khoom seem tom qab siv. 1-mcp tsis cuam tshuam rau qhov zoo ntawm cov txiv hmab txiv ntoo, tuaj yeem ncua qhov kev txo qis ntawm cov txiv hmab txiv ntoo hardness thiab titrable acid cov ntsiab lus, tswj qhov saj zoo dua, thiab txo qhov poob ntawm cov as-ham. 1-MCP kuj tseem tuaj yeem tiv thaiv cov kab mob feem ntau uas tshwm sim thaum lub sijhawm khaws cia txiv hmab txiv ntoo, xws li kab mob tawv nqaij tsov ntawm txiv apples thiab kab mob dub ntawm txiv pears. 1-Methylcyclopropene yog cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag, uas tau siv dav hauv kev lag luam.

1. Kev khaws cia txiv hmab txiv ntoo: Ncua lub sijhawm siav, txo cov kab mob thiab kev poob cov as-ham
Rau cov txiv hmab txiv ntoo uas tsim cov ethylene lawv tus kheej (lossis rhiab rau ethylene), 1-MCP tuaj yeem tswj tau qhov zoo ntawm cov txiv hmab txiv ntoo thiab yog ib qho ntawm cov ntawv thov tseem ceeb hauv kev khaws cia thiab kev thauj mus los hauv kev lag luam. 1-Methylcyclopropene tuaj yeem tiv thaiv lawv cov txiv hmab txiv ntoo kom siav sai (xws li cov tawv txiv tsawb daj ua ntej thiab cov nqaij txiv nkhaus taw mos), daws qhov teeb meem kev thauj mus los ntawm "kev puas tsuaj yooj yim tom qab sau qoob loo" rau cov txiv hmab txiv ntoo zoo li no. Nthuav dav kev muag khoom.
2. Kev khaws cia zaub: Tswj kom cov zaub tshiab thiab tshiab, thiab txo qhov lwj thiab lwj.
1-Methylcyclopropene feem ntau yog siv rau cov zaub uas xav tau kom cov zaub tawv thiab tawv lossis cov uas yooj yim poob dej thiab lwj. Nws yog qhov tsim nyog rau cov hom uas tseem muaj kev ua pa tom qab sau qoob loo thiab yooj yim raug cuam tshuam los ntawm ethylene, tswj qhov tawv ntawm cov txiv hmab txiv ntoo. 1-methylcyclopropene tiv thaiv kev lwj ntawm cov nqaij lossis kev qaug zog ntawm cov saj, thiab tib lub sijhawm txo qhov lwj los ntawm cov kab mob me me.
3. Kev khaws cia paj: Ntev lub sijhawm saib thiab txo cov paj thiab nplooj poob
Rau cov paj txiav lossis cov paj cog hauv lauj kaub uas rhiab rau ethylene, 1-MCP tuaj yeem ua rau qeeb qeeb ntawm cov paj thiab cov nplooj poob, ua rau lawv cov txiaj ntsig zoo nkauj. Cov hom siv tau suav nrog kev txo qhov poob thaum thauj mus los lossis tso rau hauv. Hmoov 1-mcp yog qhov tsim nyog rau kev thauj mus los ntev ntawm cov paj txiav tshiab thiab muag khoom hauv cov khw muag paj.
4. Lwm yam kev siv pab
Ntxiv rau kev khaws cia ncaj qha, 1-MCP kuj tseem tuaj yeem ua lub luag haujlwm tsis ncaj qha hauv kev tsim qoob loo. Thaum lub sijhawm noob ntawm qee cov qoob loo cog qoob loo (xws li cov nroj tsuag kho kom zoo nkauj), qhov concentration qis ntawm 1-MCP tuaj yeem siv los tswj lub suab ntawm cov nroj tsuag, zam kev tawg ntxov lossis laus. 1-mcp hmoov tuaj yeem pab txuas lub sijhawm khaws cia tom qab sau thiab txo qhov kev puas tsuaj ntawm cov khoom xyaw nquag rau qee cov ntaub ntawv tshuaj suav uas yooj yim.
1. Kev Huv Si: Tus qauv kev lag luam rau 1-MCP yog 3.3%, tab sis peb tuaj yeem ua tiav 3.7%.
2. Peb muaj peev xwm muab cov micro-doses, cov pob me me ntawm 0.035%, rau kev siv rau ntawm cov txee hauv khw muag khoom loj lossis hauv cov thawv txiv hmab txiv ntoo.
3. Kev Nyab Xeeb Khoom: 1-MCP yog ib qho roj molecule uas yuav ploj mus tag tom qab ua tiav, tsis muaj cov tshuaj seem ntawm cov khoom.
