Impeshyi igeze, kandi ikintu giteye urujijo kuri buri wese nukubungabunga ibiryo. Nigute ushobora kumenya neza ibiryo byahindutse ingingo ishyushye muri iki gihe. Nigute dushobora kubika imbuto n'imboga mbisi mugihe cyizuba gishyushye? Imbere yibi bibazo, mumyaka yashize, ubushakashatsi bwa siyansi bwavumbuye ikintu cyiza kibuza ibikorwa bya Ethylene -1-MCP. Inhibitor ya 1-MCP ntabwo ari uburozi gusa, butagira ingaruka, busigara ubusa, kandi bwangiza ibidukikije, ariko kandi bukoreshwa cyane mukubungabunga imbuto, imboga, nindabyo. Hasi, tuzamenyekanisha amakuru yihariye yibicuruzwa 1-MCP.
Niki 1-MCP?
1-MCP, bizwi kandi nka 1-Methylcycloprotene,CAS 3100-04-7. 1-MCP ni inzitizi nziza ya Ethylene ishobora guhagarika urukurikirane rwimyitwarire ya physiologique na biohimiki ijyanye no kwera imbuto iterwa na Ethylene, ikabuza ubukana bwubuhumekero, gutinda neza kwera imbuto no gusaza, kugumana isura yumwimerere nubwiza bwimbuto n'imboga kuri umwanya muremure, gabanya guhumeka amazi, kugabanya ibyangiritse byangirika no kwangirika kwa mikorobe, Kugirango ubungabunge ubwiza bwimbuto. Kandi 1-MCP ntabwo ari uburozi nibisigara byubusa, byujuje ibipimo bitandukanye byerekana amashusho yigihugu, kandi birashobora gukoreshwa wizeye.

Porogaramu ya MCP
Mbere yo gukoresha 1-MCP, hakoreshejwe uburyo bwinshi bwo kubungabunga no kubungabunga umubiri: 1. Gukonjesha ubushyuhe buke, 2. Kubika ikirere cyagenzuwe, na 3. Kuvura ubushyuhe, urumuri, na microwave. Nyamara, ubu buryo butatu busaba imbaraga nimbaraga nyinshi, kandi igihe ni kirekire kandi kigufi. Ubushakashatsi bwerekanye ko 1-MCP ishobora guhangana neza kugirango ihuze na reseptor ya Ethylene, gutinda kwera imbuto no gusaza. Bitewe nuburyo butagira uburozi, imikoreshereze mike, imikorere myiza, hamwe n’imiti ihamye y’imiti, kuri ubu irakoreshwa cyane mu kubika imbuto n'imboga, hamwe n’isoko rikoreshwa cyane kandi rikazamurwa mu ntera.
1-MCP ntabwo ibuza gusa cyangwa idindiza kubaho gusaza kwa physiologique mu bimera, ariko kandi ifite uburozi buke. LD50> 5000mg / kg mubyukuri ntabwo ari uburozi; Ubwinshi bwakoreshejwe buri hasi cyane, kandi mugihe utunganya imbuto, imboga, nindabyo, kwibanda mukirere bigomba kuba miriyoni imwe gusa, bityo umubare usigaye mu mbuto, imboga, nindabyo nyuma yo gukoreshwa ni muke kuburyo udashobora kumenyekana ; 1-MCP yatsinze kandi ubugenzuzi bw’ikigo cy’Amerika gishinzwe kurengera ibidukikije (itangazo ry’urubuga rwa EPA) kandi gifatwa nk’umutekano kandi udafite uburozi, bukwiriye gukoreshwa mu ndabyo n'imbuto n'imboga, kandi bifite umutekano ku bantu, ku nyamaswa, no ku bidukikije. Ntabwo ari ngombwa gushyiraho ibipimo bya dosiye mugihe cyo gukoresha.
Ni ubuhe buryo bw'isoko kuri 1-MCP?
Ku bihugu by’ubuhinzi, umusaruro mwinshi wimbuto n'imboga buri mwaka. Kubera iterambere ridatunganye ryibikoresho bikonje bikomoka kubuhinzi, hafi 85% byimbuto n'imboga bakoresha ibikoresho bisanzwe, bikaviramo kwangirika no gutakaza. Ibi bitanga isoko ryagutse ryo kuzamura no gukoresha 1-methylcyclopropene. Ibisubizo byubushakashatsi byerekana ko 1-methylcyclopropene ishobora kugabanya cyane koroshya no kwangirika kwimbuto n'imboga, kandi bikongerera igihe cyo kubika no kubika igihe. Ibi bisoza intangiriro ya1-MCP. Niba ushaka kumenya byinshi kubicuruzwa, nyamuneka umpe ubutumwa.
