Nyakanga ni impeshyi yizuba, kandi mugihe cyizuba gishyushye nubushuhe, ibiryo birashobora kuba uburyo bwera kuri bagiteri igihe icyo aricyo cyose.Cyane cyane imbuto n'imboga, niba imbuto n'imboga bishya byaguzwe bitabitswe muri firigo, birashobora kubikwa umunsi umwe gusa.Kandi buri mpeshyi, hariho ibibazo byinshi byo gucibwamo biterwa no "kurya nabi", abakuze ndetse nabana, bakunze kwibeshya ko barya "imbeho" cyane.Mubyukuri, ibiryo cyangwa ibinyobwa byubushyuhe buke bitera inshuti zimwe na zimwe kugira peristalisite zo munda byihuse, ariko mubisanzwe ntibitera abantu kwiruka mubwiherero inshuro nyinshi kumunsi.Kuri ubu rero, ikintu cya mbere ugomba gusuzuma ni indwara yo munda iterwa nisuku yibiribwa.Ibiryo biribwa birabora kandi byangirika?Nigute dushobora kurya imbuto n'imboga mbisi mugihe cyizuba gishyushye?

Kuri ubu, ikintu cya mbere dutekereza ni ububiko bwa firigo.Nyamara, hari ubwoko bwinshi bwibiribwa n'ibinyobwa bibitswe muri firigo, muri byo hakaba harimo ibiryo byinshi “bitera bagiteri” muri firigo, nk'amagi ashobora gutwara salmonella, n'inyama mbisi, imbuto n'imboga zishobora gutwara indwara ya Escherichia coli, pathogenic Staphylococcus aureus na parasite.Firigo nayo ifite ubuzima bubi bwo kubungabunga.Mubisanzwe, ibiryo bifata iminsi 2-3 bigomba kuribwa, bitabaye ibyo bizabora muri firigo mugihe runaka.Muri icyo gihe, firigo nayo ifite umubare munini wububiko, bukoreshwa gusa murugo.Niba ari supermarket nini, nigute dushobora kubika ibiryo bishya kubacuruzi baturuka?

Hamwe niterambere ryiterambere ryubukungu, kwinjiza no kohereza imbuto n'imboga bimaze kuba akamenyero.Imbere yibi bihe, tugomba kwiga ubwoko bushya bwo kubungabunga -1-MCP imbuto n'imbuto zo kubungabunga imboga.Ibicuruzwa bimaze gutezwa imbere, byakiriye igisubizo kinini.Kuberako ibi ari uburozi, umutekano muke, kandi birinda cyane kubungabunga ibidukikije.Ibikurikira, reka tuvuge kubintu bigize 1-MCP imbuto n'imboga zibika.

Niki 1-Methylcyclopropene?

1-Methylcyclopropene, mu magambo ahinnye nka 1-MCP mu Cyongereza,CAS 3100-04-7imiti yimiti ni C4H6.Mubushyuhe busanzwe nigitutu, isura ni gaze itagira ibara, idafite uburozi kandi itaryoshye, hamwe nubucucike bwa 0.838g / cm3.Nibintu bikora cyane Cyclopropene.1-Methyl Cyclopropene ikoreshwa cyane cyane mugukuza ibimera kandi ikoreshwa cyane mubijyanye no kubungabunga ibimera.Ifite ibyiza byo gukoresha bike, ingaruka nziza zo kubungabunga n'umutekano mwinshi.

Ibiranga 1-MCP

1-MCP irashobora kubuza irekurwa rya Ethylene n’ibimera ubwabyo, kandi bikanabuza guhuza Ethylene na reseptor bifitanye isano na selile ziterwa n’ibimera, bityo bikabuza ingaruka zeze za Ethylene.Kubwibyo rero, gukoresha 1-Methylcyclopene birashobora kongera igihe cyo gukura no gusaza kwibimera, bityo bikongerera igihe cyo kuramba, kugabanya ruswa n’imyanda mugihe cyo gutwara no kubika, no kongera igihe cyibicuruzwa.

Porogaramu ya 1-MCP

1-MCPIrashobora gukoreshwa mukubungabunga imbuto, imboga, nindabyo kugirango ibimera bitangirika.Kurugero, iyo ushyizwe ku mbuto n'imboga nka pome, amapera, pome, kiwifruit, ninyanya, birashobora gutinda kwera, kugabanya amazi, kandi bikagumana ubukana, uburyohe, hamwe nimirire;Mu rwego rwo kubungabunga indabyo, irashobora kugumana ibara n'impumuro nziza yindabyo.Byongeye kandi, 1-Methylcyclopene irashobora kandi kunoza indwara ziterwa n’ibimera.1-Methylcyclopeneni intambwe nshya mu kubungabunga imbuto n'imboga nyuma yo kubungabunga ikirere cyahinduwe.

Nyuma y'icyorezo, ubukungu bwifashe neza, kandi iterambere ry'ubucuruzi ku isi ryagendaga ryiyongera.Buri mwaka, buri gihugu cyatanga umusaruro mwinshi wimbuto n'imboga byaho.Bitewe niterambere ridatunganye ryibikoresho bikonje bikomoka ku buhinzi, hafi 85% byimbuto n'imboga byakoreshaga ibikoresho bisanzwe, bikaviramo igihombo kinini cyangirika, ari nako byatanze isoko ryagutse ryo kuzamura no gushyira mubikorwa1-methyl Cyclopropene.Kubwibyo, birashobora kugaragara ko 1-MCP ifite amahirwe menshi yiterambere, atari kubwimbuto nimboga zitandukanye zubuhumekero gusa, ariko kandi irashobora kwagura neza ububiko bwibisarurwa hamwe nubuzima bwa tekinike, cyane cyane kubibuto n'imboga byoroshye bya Ethylene, kandi bishobora gukomeza umwimerere. ubwiza bwimbuto n'imboga igihe kirekire.
