5-Hydroxymethylfurfural (5-HMF), zvakare iri CAS 67-47-0, ndeye yakasikwa organic compound inotorwa kubva kushuga. Ndiyo yakakosha yepakati mukugadzirwa kwemakemikari akasiyana-siyana, anoshandiswa sechinhu chinonhuwira muindasitiri yechikafu, uye anoshandiswa mukugadzirwa kwemishonga yakasiyana siyana muindasitiri yemishonga. Nekudaro, pane kunetsekana nezve zvingangokuvadza zvinokonzeresa zve5-hydroxymethylfurfural pahutano hwevanhu.
5-Hydroxymethylfurfuralinowanzowanikwa mune zvakasiyana-siyana zvekudya zvinopisa, kunyanya izvo zvine shuga kana high-fructose corn syrup. Inoumbwa panguva yeMallard reaction, kemikari inopindirana pakati peamino acids uye kuderedza shuga inoitika kana chikafu chichipisa kana kubikwa. Semagumo,5-HMFinowanikwa mune zvakasiyana-siyana zvekudya zvakagadzirwa, kusanganisira zvakabikwa, michero yemumagaba nemiriwo, uye kofi.
Izvo zvinogona kukuvadza zvinokonzerwa ne5-hydroxymethylfurfuraldzave dziri nyaya yekutsvagisa kwesainzi uye gakava. Zvimwe zvidzidzo zvinoratidza kuti mazinga akakwirira e5-HMF muzvikafu angave akabatana nehutano husina kunaka, kusanganisira genotoxicity uye carcinogenicity. Genotoxicity inoreva kugona kwemakemikari kukuvadza ruzivo rwemajini mukati memasero, izvo zvinogona kutungamira mukushanduka kana kenza. Carcinogenicity, kune rumwe rutivi, inoreva kugona kwechinhu kukonzera gomarara.
Nekudaro, zvakakosha kucherechedza kuti mazinga e5-hydroxymethylfurfuralmuzvokudya zvizhinji zvinowanzonzi hazvina ngozi kudyiwa nevanhu. Masangano anodzora akadai seUS Food and Drug Administration (FDA) neEuropean Food Safety Authority (EFSA) vakagadzira nhungamiro yemazinga anogamuchirwa e5-HMF muchikafu. Iyi nhungamiro yakavakirwa patsvagiridzo yesainzi yakakura uye yakagadzirirwa kuve nechokwadi chekuchengetedzwa kwevatengi.
Pamusoro pekuvapo kwayo muchikafu, 5-hydroxymethylfurfural inoshandiswa mune dzakasiyana siyana maindasitiri ekushandisa. Iyo yakakosha yepakati mukugadzirwa kwemakemikari efuran, ayo anoshandiswa kugadzira resin, mapurasitiki nemishonga. 5-HMF zvakare iri kudzidzwa senge ingangoita bio-yakavakirwa papuratifomu kemikari yekugadzirwa kwemafuta anogona kudzokororwa nemakemikari.
Kunyange zvazvo pane kunetseka pamusoro pezvinokuvadza zvinokonzerwa ne5-hydroxymethylfurfural, zvakakosha kuti uzive kuti iyi komputa inewo yakakosha maindasitiri ekushandisa uye ndeye yakasikwa byproduct yekubika nekudziya chikafu. Sezvinoita makemikari mazhinji, kiyi yekuve nechokwadi chekuchengetedza ndeyekunyatso tarisa uye kugadzirisa mashandisiro avo uye mazinga ekuratidzwa.
Muchidimbu, nepo paine zvimwe zvinonetsa pamusoro pezvinogona kukuvadza mhedzisiro ye5-hydroxymethylfurfural, kunyanya zvine chekuita nekuvapo kwayo muchikafu, humbowo hwesainzi hwazvino hunoratidza kuti inowanikwa muzvikafu zvakawanda pamatanho anowanzoonekwa akachengeteka kudyiwa nevanhu. Masangano anodzora akagadzira nhungamiro yekuona kuchengetedzwa kwevatengi, uye zvidzidzo zviri kuenderera mberi nekunzwisisa zvinogona kuitika pahutano hwekomboni. Sezvinoita chero kemikari, zvakakosha kuenderera mberi nekutarisa kushandiswa kwayo uye kuratidzwa mazinga kuti ive nechokwadi chekuchengetedzwa kwevatengi nevashandi muindasitiri.
