Ihlobo lifikile, kwaye eyona nto ididayo kuye wonke umntu kukugcinwa kokutya. Indlela yokuqinisekisa ukuba ukutya kutsha ibe ngumxholo oshushu kule mihla. Ngoko ke singazigcina njani iziqhamo nemifuno emitsha xa kujongwe ihlobo elishushu kangaka? Ngenxa yale meko, kwiminyaka yakutshanje, uphando lwezenzululwazi lufumanise isithinteli esisebenzayo sesenzo se-ethylene -1-MCP. Isithinteli se-1-MCP asipheleli nje ekubeni singenabungozi, asinabungozi, asinantsalela, kwaye sinobuhlobo nokusingqongileyo, kodwa sikwasetyenziswa kakhulu ukugcina iziqhamo, imifuno kunye neentyatyambo. Ngezantsi, siza kwazisa iinkcukacha ezithile zemveliso ye-1-MCP.
Yintoni i-1-MCP?
1-MCP, ekwaziwa ngokuba yi-1-Methylcycloprotene,I-CAS 3100-04-7. I-1-MCP sisithinteli se-ethylene esisebenzayo esinokuthintela uthotho lweempendulo zomzimba nezebhayoloji ezinxulumene nokuvuthwa kweziqhamo okubangelwa yi-ethylene, sithintele amandla okuphefumla kwezityalo, silibazise ngempumelelo ukuvuthwa kweziqhamo kunye nenkqubela yokwaluphala, sigcine imbonakalo yokuqala kunye nomgangatho weziqhamo nemifuno ixesha elide, sinciphise ukufuma kwamanzi, sinciphise umonakalo wezifo kunye nokubola kweentsholongwane, Ukugcina umgangatho wokugcina wesiqhamo. Kwaye i-1-MCP ayinatyhefu kwaye ayinantsalela, ihlangabezana neempawu ezahlukeneyo zezixhobo zokugcina ividiyo zesizwe, kwaye ingasetyenziswa ngokuzithemba.

Isicelo se-1-MCP
Ngaphambi kokusetyenziswa kwe-1-MCP, uninzi lweendlela zokugcina nokugcina umzimba zasetyenziswa: 1. ukukhenkceza kwiqondo lobushushu eliphantsi, 2. ukugcina umoya olawulwayo, kunye 3. unyango lobushushu, ukukhanya, kunye ne-microwave. Nangona kunjalo, ezi ndlela zintathu zifuna abasebenzi abaninzi kunye nezixhobo, kwaye ixesha lide kwaye lifutshane. Uphando lubonise ukuba i-1-MCP inokukhuphisana ngempumelelo ukubopha kwi-ethylene receptors, ibambezele ukuvuthwa nokuguga kweziqhamo. Ngenxa yeempawu zayo ezingenabungozi, ukusetyenziswa okuphantsi, ukusebenza kakuhle, kunye neempawu zeekhemikhali ezizinzileyo, okwangoku isetyenziswa kakhulu ekugcineni iziqhamo nemifuno, kunye nezinga eliphezulu lokusetyenziswa kwimarike kunye nokukhuthaza.
I-1-MCP ayithinteli okanye ilibazise kuphela ukwenzeka kokwaluphala komzimba kwizityalo, kodwa ikwanobungozi obuphantsi. I-LD50>5000mg/kg ngokwenene yinto engenabungozi; Uxinzelelo olusetyenziswayo luphantsi kakhulu, kwaye xa kusetyenzwa iziqhamo, imifuno, kunye neentyatyambo, uxinzelelo emoyeni kufuneka lube sisigidi esinye kuphela, ngoko ke inani eliseleyo kwiziqhamo, imifuno, kunye neentyatyambo emva kokusetyenziswa liphantsi kakhulu kangangokuba alinakubonwa; I-1-MCP ikwaphumelele uhlolo lwe-US Environmental Protection Agency (isaziso sewebhusayithi ye-EPA) kwaye ithathwa njengekhuselekileyo kwaye ayinabungozi, ifanelekile ukusetyenziswa kwiintyatyambo, iziqhamo, kunye nemifuno, kwaye ikhuselekile ebantwini, kwizilwanyana, nakwindalo esingqongileyo. Akukho mfuneko yokumisela imiqathango yomthamo ngexesha lokusetyenziswa.
Injani imbonakalo yemarike ye-1-MCP?
Kumazwe ezolimo, inani elikhulu leziqhamo nemifuno emitsha iveliswa minyaka le. Ngenxa yophuhliso olungaphelelanga lwe-cold chain logistics yeemveliso zezolimo, malunga ne-85% yeziqhamo nemifuno zisebenzisa i-logistics eqhelekileyo, nto leyo ebangela ukubola nokulahleka okukhulu. Oku kubonelela ngendawo ebanzi yemarike yokukhuthaza nokusetyenziswa kwe-1-methylcyclopropene. Iziphumo zophando zibonisa ukuba i-1-methylcyclopropene inokunciphisa kakhulu ukuthamba nokubola kweziqhamo nemifuno, kwaye yandise ixesha lokuhlala kwazo kunye nexesha lokugcina. Oku kugqiba ukwaziswa kwe-1-MCPUkuba ungathanda ukwazi okungakumbi ngale mveliso, nceda undishiyele umyalezo.
