3-hydroxy-2-methyl-4h-pyran-4-ib (tseem npe hu ua Maltol, Larixinic acid, Palatone thiab Veltol) yog lub ntuj tsim. Maltol yog pom hauv cov nqaij, cov malt ci, khob cij, mis nyuj, roj ncau roj, cov nqaij npuas uas tsis haus luam yeeb, cocoa, kas fes, ci pob kws, txiv laum huab xeeb, roasted txiv laum huab xeeb, taum txiv ntoo, hauv cov tawv ntoo ntawm tsob ntoo, hauv koob koob, thiab hauv malt (los ntawm qhov uas nws tau txais nws lub npe) lwm yam Nws muaj qhov tsw ntawm paj rwb khaub noom thiab caramel. Maltol muaj qhov sov sov, qab zib, txiv hmab txiv ntoo tsw thiab muaj ntxhiab tsw-zoo li jam hauv kev daws. Nws yuav npaj tau los ntawm alkaline hydrolysis ntawm tus kab mob streptomycin ntsev; kuj los ntawm piperidine rau pyromeconic acid thiab tom qab methylation ntawm 2 txoj hauj lwm.

Maltol yog dav siv los ua cov tshuaj tsw qab txhim kho qhov ncauj thiab ua rau lub tsw qab ntawm khoom qab zib thiab khoom noj ci rau hauv cov khoom noj thiab cov dej qab zib hauv kev lag luam haus. Nws yog siv raws li nruab nrab hauv kev ua tshuaj rau kev tsim tshuaj. Nws yog siv los ua txuj lom nyob hauv kev kho kom zoo nkauj thiab tus kheej saib xyuas kev lag luam txhawm rau txhim kho qhov tsw. Raws li FEEDAP Vaj Huam Sib Luag, maltol muaj kev nyab xeeb ntxiv rau kom pub rau txhua tus tsiaj cov tsiaj ntawm qhov kev siv theem li ntawm 5 mg / kg pub.
