Chifukwa chiyani chokoleti imayenera kutenthedwa?

Chokoleti amapangidwa kuchokera ku njere za mtengo wa koko.Makoko a koko amafufuzidwa, kuuma, ndikuwotcha kuti apeze nyemba za koko, zomwe zimakhala ndi mafuta pafupifupi 51% mpaka 55%, omwe amatchedwa "cocoa butter".

Mafuta a Cocoa ndi owopsa kwambiri.Amapangidwa ndi mitundu yosiyanasiyana ya mafuta acids, ndipo chiŵerengero chake ndi chosiyana kwambiri ndi mafuta ena.Monga tawonera m'chithunzi chomwe chili pansipa, mayendedwe ake olimba amafuta amafananizidwa ndi batala, batala ndi mafuta ena.Ndi potsetsereka kwambiri.Zimayamba kufewa pa madigiri 28 Celsius, ndipo zolimba zimasanduka madzi pa madigiri 33 Celsius.

N'chifukwa chiyani chokoleti chimakhala cholimba komanso cholimba kutentha kwa chipinda, ndipo chimakhala chophwanyika chikalumidwa, koma chimasungunuka m'kamwa?

N'chifukwa chiyani chokoleti chimakhala cholimba komanso cholimba kutentha kwa chipinda, ndipo chimakhala chophwanyika chikalumidwa, koma chimasungunuka m'kamwa?

Ndi malo opapatiza osungunuka a batala wa cocoa omwe ali pafupi ndi kutentha kwa thupi la munthu komwe kumapangitsa kukoma kwa chokoleti.

Kulumikizana kosasunthika kwa kutentha!Kodi pangakhale bwanji kumverera kuti kukhalapo kwa chokoleti ndikukwaniritsa chikhumbo chaumunthu cha chakudya?

Mwachindunji, batala wa cocoa ali ndi mitundu yosiyanasiyana yamafuta olimba a crystalline.

Nthawi zambiri pamakhala mitundu inayi yodziwika bwino, yomwe ndi γ, α, β', β.Pazikhalidwe zosiyanasiyana za kutentha, kutembenuka kwa mawonekedwe a kristalo kukuwonetsedwa pachithunzi chotsatirachi:

Malo osungunuka a γ-mtundu wa kristalo ndi 16 ~ 18 ℃, yomwe imakhala yosakhazikika, ndipo idzasintha kukhala α-mtundu pafupifupi 3 masekondi.Zosawerengeka.

Mapangidwe a makristalo ena atatu akuwonetsedwa pachithunzi pansipa:

makhiristo amtundu wa α (mtundu I ndi II): malo osungunuka 17 ~ 23 ℃, amasandulika kukhala kristalo wamtundu wa β' mu ola limodzi kutentha.Maonekedwe ake ndi ofewa, osalimba komanso osavuta kusungunuka.

Makhiristo amtundu wa β' (mtundu wa III ndi IV): malo osungunuka 25 ~ 28 ℃, adzasandulika kukhala kristalo wamtundu wa β m'mwezi wotsatira kutentha.Maonekedwe ake ndi olimba, osati ophwanyika, komanso osavuta kusungunuka.

Makristasi olimba kwambiri amtundu wa β (V-mtundu ndi VI-mtundu) ali ndi malo osungunuka a 33 ~ 36 ° C, okhala ndi mawonekedwe olimba komanso osasunthika, ndi kutentha kosungunuka pafupi ndi kutentha kwa thupi la munthu.Komabe, makristalo okhazikika amtundu wa VI okhala ndi malo osungunuka kwambiri amakhala owoneka bwino komanso amakoma, ndipo amatulutsa pachimake chamafuta pamwamba (ndichifukwa chake "nthambi ya "hoarfrost" imapangidwa pamwamba pa chokoleti patatha nthawi yayitali. nthawi), kotero ndi Metastable V woboola pakati makhiristo omwe ali okhazikika komanso owoneka bwino asanduka mawonekedwe abwino kwambiri amafuta.

Cholinga cha kusintha kwa kutentha ndikusungunula chokoleti ndikusintha kutentha kuti mupeze mawonekedwe abwino kwambiri a homogeneous polymorphism, kupatsa chokoleti kukhala chokoma, chokoma komanso chowoneka bwino chonyezimira.

Kubwereranso ku kutentha zinayi zomwe tazitchula pamwambapa, nchifukwa chiyani malo ozizira achiwiri a chokoleti chowawa mpaka 28 ° C?

Ndiko kupewa kupanga makhiristo ena osafunika mu batala wa cocoa, zomwe zingakhudze mtundu wa chokoleti yomalizidwa.

Kuonjezera apo, phala la koko ndi shuga mu chokoleti zidzakhudzanso ndondomeko ya crystallization, koma kunena kwake, sizofanana ndi kusintha kwa kutentha, kotero sindidzatchula pano kwa nthawiyi.

Ndiye, mungafulumizitse bwanji kuzirala kuti mupange makhiristo ooneka ngati V?

Kodi kutentha kumayenera kusinthidwa bwanji?

Tengani chokoleti chamkaka chodziwika kwambiri monga chitsanzo:

CHOCHITA1: Nthawi zambiri, njira yowotchera m'madzi imagwiritsidwa ntchito kusungunula chokoleti.Monga momwe chithunzi chili pansipa, chimatenthedwa mpaka 40 ° C m'madzi.Panthawiyi, iyenera kugwedezeka mosalekeza, ndipo samalani kuti musalole nthunzi yamadzi kulowa mu chokoleti.

CHOCHITA 2: Pali njira zambiri zoziziritsira, monga kuziziritsa madzi, tableage, seeding, etc.

Njirazi ndikuziziritsa chokoleti mwachangu kuti mupewe kupangika kwa makristalo a VI okhala ndi tinthu tambirimbiri komanso kukoma koyipa.

Tengani chitsanzo cha njira yomwe imagwiritsidwa ntchito kwambiri komanso yokongola kwambiri yozizirira pagome la nsangalabwi.Thirani magawo awiri mwa atatu a chokoleti chosungunuka mofanana pa tebulo la marble.

Gwiritsani ntchito spatula kuti mufufuze mobwerezabwereza ndikudula mpaka chokoleti ikhale wandiweyani ndikuyamba kumamatira ku spatula ndipo simungathe kutsika.Chithunzi chili pansipa ndi chitsanzo.

Panthawiyi, kutentha kumakhala pafupifupi 25 ° C, ndipo makhiristo abwino amafuta apanga.Ndikoyenera kukwapula chokoleti chonse patebulo kubwerera mumphika woyambirira nthawi yomweyo, ndipo kutentha kusapitirire kuchepa kuti apange makhiristo amtundu wa β' kapena makhiristo amtundu wa α.

Ngati kutentha kuli kotsika kwambiri, kutentha kumayenera kusinthidwanso kuchokera pa sitepe yoyamba.

CHOCHITA 3: Kuwothanso.Pewani chokoleti chonse patebulo kubwerera mumphika woyambirira ndikusakaniza ndi chokoleti chosasungunuka.Kutentha panthawiyi ndi pafupifupi 30 ° C.Ngati chokoleti ndi viscous kwambiri pansi pa 30 ° C pa sitepe yotsatira, ikhoza kutenthedwa pang'ono mpaka 30 ° C m'madzi.

Gawoli liyenera kusamala, ngati kutentha kuli kwakukulu, makhiristo amafuta adzasungunukanso, ndipo kutentha kuyenera kusinthidwanso kuyambira pa sitepe yoyamba.

Chotsatira, chokoleti chomwe chatenthedwa chingagwiritsidwe ntchito kupitiriza kuumba jekeseni, kuviika, ndi kupanga ntchito.

Koma komabe muyenera kumvetsera, ndi bwino kugwiritsa ntchito zipangizo zotetezera kutentha kuti muzitha kutentha, pamene kutentha kumakhala kozizira kwambiri, chokoleti chiyenera kukhazikitsidwa kachiwiri.

Chifukwa chake, chokoleti ndi chinthu chovuta kwambiri.Zimakhudzidwa kwambiri ndi kutentha ndi chinyezi.Ngati pali kusasamala pakusintha kwa kutentha, kuyenera kuyambiranso, zomwe zimakhala zovuta kwambiri.
