Ethyl maltol, monga chowonjezera chokometsera bwino komanso chosunthika, chimagwiritsidwa ntchito kwambiri m'makampani azakudya kuti apititse patsogolo kukhudzika kwazinthu komanso mtundu wonse wazakudya kudzera kununkhira kwake kosiyana ndi magwiridwe antchito. Nkhaniyi ikufotokoza mwachidule njira zogwiritsira ntchito, mfundo zazikuluzikulu, ndi malingaliro ovuta pakugwiritsa ntchito ethyl maltol.
Ethyl maltol, yomwe imadziwikanso kuti 3-hydroxy-2-ethyl-4-pyrone, ili ndi mamolekyu a C7H8O3 ndi molekyulu yolemera 140.14. Zikuwoneka ngati kristalo woyera kapena wotumbululuka wachikasu wokhala ndi fungo la caramel komanso fungo la zipatso. Kapangidwe kake ka ethyl maltol kumapereka mawonekedwe apadera a physicochemical, kuphatikiza kusungunuka kwabwino m'madzi otentha, ethanol, chloroform, ndi glycerol, pomwe akuwonetsa kusungunuka kochepa m'madzi ozizira. Kusungunuka kwake kumawonjezeka ndi kutentha; pa 15 ° C, pafupifupi 1 g imasungunuka pafupifupi 65 ml ya madzi, pamene pa 25 ° C, pafupifupi 1 g imasungunuka pafupifupi 55 ml ya madzi. Ethyl maltol imakhudzidwa ndi acidic komanso zamchere, imasanduka yachikasu ikakhudzidwa ndi zamchere. Imasungunuka pa kutentha kwa 89-92 ° C ndipo imatha kutsika pansi pamikhalidwe yapadera. Makhalidwewa amathandizira kuti alowe nawo m'kukonza chakudya molingana ndi zofunikira zaukadaulo.
Gulu ndi Mapulogalamu
Kugawika kwa ethyl maltol kumatengera mawonekedwe ake onunkhira, kuphatikiza mitundu yonunkhira bwino, mitundu yowotcha, ndi mitundu yapadera ya mowa. Ethyl maltol yoyera imadziwika ndi fungo lofewa la fruity komanso milky. Mtundu wokometsera wa caramel umasonyeza fungo lokoma la caramel, pamene mtundu wa mowa wapadera, wokhala ndi chiyero chapamwamba ndi fungo lodziwika bwino, ndi woyenera kupititsa patsogolo kununkhira kwa nyama yapamwamba. Ethyl maltol imapeza ntchito zambiri m'magulu osiyanasiyana azakudya, kuphatikiza mkaka, zophika, zophika, maswiti, zokometsera, ndi nyama. M'zakudya zamkaka, zimawonjezera mawonekedwe owoneka bwino komanso ma nuances apadera. Muzakudya zotsekemera, zimawonjezera kununkhira kwa vanila ndi chokoleti ndikuchepetsa zolemba zowuma. Muzowotcha, zimakhala ngati zowonjezera kukoma, kuwongolera kukoma kwa makeke ndi zinthu zina zofananira. M'maswiti ndi chokoleti, amawonjezera kununkhira komanso kusalala kwinaku amachepetsa kuwawa. Mu zokometsera ndi masukisi, zimawonjezera kutsekemera ndi kununkhira kwinaku zimachepetsa kununkhira kowawasa komanso kowawa. Muzinthu za nyama, zimagwirizanitsa ndi zowonjezera zina kuti ziwonjezere mtundu ndi kukoma.
Ntchito Yogwira Ntchito
Kugwira ntchito kwa ethyl maltol kumapitilira kuwonjezera kununkhira. Ikhoza kupanga ma complexes okhala ndi ayoni achitsulo mu myoglobin, kuteteza kuwonongeka kwa myoglobin ndipo potero kusunga mtundu ndi kukoma kwa nyama. Kuphatikiza apo, ethyl maltol imapereka maubwino angapo, monga kuwonjezera kutsekemera, kusintha kuwawa ndi kupwetekedwa mtima, kukonza mawonekedwe otsekemera a mkaka, komanso kuchepetsa kuwawa ndi acidity.
Malangizo Ogwiritsa Ntchito
Mukamagwiritsa ntchito ethyl maltol, kutsatira mfundo ndi njira zodzitetezera ndikofunikira kuti mutsimikizire chitetezo chazakudya komanso zabwino. Choyamba, ngakhale kuti ethyl maltol yatsimikiziridwa kuti ndi yotetezeka kupyolera mu kuyesa kwakukulu, kugwiritsidwa ntchito kwake kuyenera kukhalabe m'malire omwe atchulidwa. Chachiwiri, kukhudzana ndi zinthu zomwe zili ndi iron kuyenera kupewedwa kuti zisawonongeke. Kugwiritsa ntchito pansi pamikhalidwe yamchere kuyeneranso kupewedwa kuti mupewe chikasu. Kuphatikiza apo, ethyl maltol nthawi zambiri imawonjezedwa pambuyo pake pakuwotcha popanga njira zochepetsera kuphulika. Kuphatikiza apo, kusakanikirana kokwanira ndi zinthu zina ndikofunikira kuti tikwaniritse kugawa kofanana.
Pomaliza, ethyl maltol, monga chowonjezera chazakudya zambiri, imagwira ntchito yofunika kwambiri pakukulitsa chidwi chambiri komanso mtundu wonse wazakudya. Komabe, kugwiritsa ntchito kwake kuyenera kuika patsogolo chitetezo cha chakudya.
