Chifukwa chiyani tikamagula chokoleti timachotsa pashelufu kutentha kwapakhomo, timayika m'firiji?
Ndi zosangalatsa zomwe timakhala nazo posintha zinthu kuzungulira ... kuchokera m’mashelufu ake ndi m’nyumba mwathu sitimaziika m’mbale, koma m’firiji.
Mwachitsanzo, tikamagula mazira kutentha, nchifukwa ninji amangokhala pa umodzi mwa mashelufu a firiji yathu? Yofotokozedwa ndi a Luis Riera, director director a SAIA, ngati dzira ndi limodzi kutentha kotsika kwa 25ºC, Ikhoza kusungidwa popanda vuto kutentha kwa firiji, kotero palibe chomwe chingachitike ngati tili ndi chizolowezi chowayika pamenepo. Komano, zomwezo sizichitika ndi mipiringidzo ya chokoleti…
Chokoleti mufiriji, inde kapena ayi?
Nthawi zambiri timawona khonde lalitali lokhala ndi mashelufu odzaza ndi chokoleti, ndipo titafika kunyumba ndikukagula, timayika nthawi yomweyo chokoleti mu furiji… Chisankho, mwachiwonekere, sichanzeru kwambiri, malinga ndi akatswiri azakudya.
«Sizingakhale bwino kuyika mapiritsiwa mufiriji chifukwa chimodzi mwazomwe zimakhala ndi chokoleti, chomwe chimatisangalatsa, ndicho Zimasungunuka mosavuta pakamwa pathu. Izi zimachitika ngati chokoleti chidapangidwa bwino, chisungidwe bwino ndipo timalawa kutentha koyenera. Kuphatikiza apo, ikasungunuka imatulutsa zonunkhira zonse ndipo titha kuyamikira kununkhira bwino kwambiri », atero a Luis Riera. Chifukwa chake, sitingakhale okhutira ngati titadya chokoleti choterechi kutentha pang'ono.
Mwachiwonekere, chokoleti chimapangidwa koko ndi zolimba za shuga zimayimitsidwa mu batala wa koko: zolimba zimapereka kununkhira komanso batala wa cocoa kapangidwe kake. Luis Riera akuti batala wa koko yemwe amakhala ndi chokoleti, ngati atakulungidwa bwino, ali ndi malo osungunuka ofanana ndi kutentha kwa thupi lathu ndipo amasungunuka mosavuta. M'malo mwake, crystallization yasinthidwa ndipo malo osungunuka nawonso: «Ngati tilawa chokoleti chozizira, kuchokera mufiriji, sichingasungunuke mosavuta mkamwa mwathu popeza zonunkhira sizidzawoneka mosavuta ndipo titaya zonunkhira zabwino ndi chisangalalo, "akutero.
Kodi "pachimake cha mafuta" ndi chiyani?
Mwina mwazindikira kuti chokoletiyo ikangotuluka kumene mufiriji, sichimawoneka ngati mdima wakuda, koma choyera choyera chimakwirira mtunduwo chokoleti. Chifukwa chiyani izi? "Chophimba" ichi chomwe chimadziwika kuti kuphulika kwa mafuta kapena "mafuta pachimake" chimachitika chifukwa kapangidwe ka mafuta achokoleti kamapangitsa kapangidwe kake kupanga makhiristo olimba, ndipo makhiristowa amabwera m'mitundu isanu ndi umodzi yomwe imasungunuka munjira zosiyanasiyana.
«Kuchokera pakatenthedwe ka 36ºC, makhiristo onse amasungunuka ndipo tikatsitsa kutentha kotsika 36ºC, mafuta amabwereranso, koma satero, koma m'mawu omwe amasintha kapangidwe kake, motero, sawalitsa momwemonso ndipo alibe kuwala kofanana, amapereka kukoma kokometsetsa, kapangidwe kake ... ”, akufotokoza Beatriz Robles, katswiri wachitetezo cha chakudya. Koma izi sizikutanthauza kuti chokoleti ili ndi vuto lililonse kuchokera kumalo otetezera chakudya, koma kuti kuchokera pamalingaliro amakhala "chokoleti choyipa kwambiri".
Luis Riera akuwonetsa kuti kusintha kwakusunganso kumakhudzana kwambiri ndi kapangidwe koyera: «Ngati titagula chokoleti chokonzedwa bwino ndikusungidwa bwino, mawonekedwe ake adzakhala osalala, yunifolomu komanso owala. Ngati chokoleti chomwecho sichinasungidwe bwino, mawonekedwe ake azikhala oyera ndipo kapangidwe kake kasintha ndi crystallization.
Ngati malo osungira ndi malo pomwe kutentha kumasintha kwambiri, idzapangidwa… «Mwachitsanzo, malo omwe anthu onse akadzatsegula, amawotcha mpweya ndikuwuzimitsa ukatseka. Izi zimapangitsa kuti kutentha kozungulira kukakhala kwakukulu, gawo lina la batala la koko lomwe limapezeka mu chokoleti limasungunuka ndikukwera pamwamba. Ndipo kutentha kukangotsika, batala wa koko amayambiranso, koma mosalamulirika komanso molakwika, osungunuka kwambiri, "akutero katswiriyo. Ngati kusintha kwa kutentha kumakhala kozungulira, komwe kumabwerezedwa pafupipafupi, chokoleti Zidzakhala zonyezimira ndipo sizisungunuka mosavuta pakamwa pathu.
«Chimake cha shuga»
Katswiri wokhudzana ndi chitetezo cha chakudya Beatriz Robles akuwonetsa kuti vuto lomwe tili nalo ndi firiji ndikusintha kozizira kuzizira, ndiye kuti, tikazitulutsa kutentha, madzi amakhala pamwamba pa chokoleti ndipo izi zimapangitsa ikhoza kusungunula shuga ndi crystallization yomwe imapangitsanso wosanjikiza yoyera wotchedwa «shuga pachimake»:« Chinyezi chomwe chakhala pamwamba pa chokoleti, chifukwa cha kutentha kwa nyengo chifukwa cha kusintha kwa kutentha, kuyambitsa «pachimake cha shuga», microscopic recrystallization ya shuga, Kupanga gawo loyera kwambiri loyera ». Katswiri wa zaumoyo amalimbikitsanso kuti, ngati chokoleti sichingasungidwe pamalo otentha, kukulunga bwino kapena "ikani mkati mwa chidebe kuti mupewe kusintha kumeneku."
