Ilaa intee kareemku sii cusboonaado adhululubo gaas(Weel bakhaar ah oo ay ka buuxaan gaaska nitrogen dioxide ee la tuuri karo) waxay ku xidhan tahay dhawr arrimood, oo ay ku jiraan in xasiliyayaal lagu daray, xaaladaha kaydinta iyo haddii dib loo hawo-qaaday.
Waxaa lagu talinayaa in la isticmaalo kareemka la dubay isla markiiba, laakiin haddii ay jiraan wax hadha, waxaa lagu kaydin karaa qaboojiyaha ilaa 1 maalin. Haddii aad rabto in kareemkaagu uu sii dheeraado, ku dar qaboojiyaha inta lagu jiro habka karbaashka, sida jelatin, budada caanaha la duray, istaarijka galleyda ama budada pudding degdega ah. Kareemka la shiiday habkan wuxuu ku hayn doonaa qaboojiyaha 3 ilaa 4 maalmood. Haddii aad rabto in kiriimkaagu uu sii ahaado mid cusub, ka fiirso inaad ku shubto shabaqlahaaga gaasta nitrogen dioxide, kaas oo ku hayn doona qaboojiyaha ilaa 14 maalmood.
Waxa kale oo muhiim ah in la kaydiyo kareemka hadhaaga ah, kareemka dufanka waxaa lagu kaydin karaa iyadoo shaandho la dul saarayo saxanka si ay dareere kasta ugu tifqdo xagga hoose ee saxanka halka kareemku uu sii ahaado xagga sare, isagoo ilaalinaya tayada ugu fiican. Isla mar ahaantaana, waa inaad iska ilaalisaa isticmaalka 10% ugu dambeeya ee kareemka oo ay ku jiraan dareere badan, taas oo keeni karta hoos u dhaca tayada kareemka.
Caadi ahaan, kareemka guriga lagu sameeyo ayaa cusub ku ahaan doona 1 maalin mashiinada wax garaaca, iyo kareemka Darwishka leh ee xasiliyahu waxa uu sii ahaan karaa mid cusub ilaa 4 maalmood. Intaa waxaa dheer, kareemku sidoo kale waa la barafaysan karaa oo la kaydin karaa. Kareemka la qaboojiyey ayaa lagu tuujin karaa qaab gaar ah waxaana lagu ridi karaa qaboojiyaha ilaa uu adag yahay, ka dibna loo wareejiyo bac xiran si loo kaydiyo oo loo baahan yahay in mar kale la qaboojiyo ka hor inta aan la isticmaalin.
Guud ahaan, haddii aan xasiliye la isticmaalin, waxaa guud ahaan lagu talinayaa in la isticmaalo kareemka duriinka aan la furin 1 maalin gudaheed. Si kastaba ha noqotee, haddii xasiliye lagu daro, ama shaambo laga buuxiyo gaaska dioxide ee nitrogen, wakhtiga cusub ee kareemku waa la kordhin karaa ilaa 3-4 maalmood ama xitaa 14 maalmood. Waa in la ogaadaa in haddii kareemka Darwishka uu ku jiro qaboojiyaha in ka badan wakhtiga lagu taliyey, ama haddii uu noqdo caaryo, kala sooca, ama lumiyo mugga, waa in aan la isticmaalin. Had iyo jeer hubi tayada ka hor intaanad isticmaalin si aad u hubiso inaysan jirin xumaan si loo hubiyo badbaadada iyo caafimaadka.
