Itshokholethi ibisoloko iyinto ethandwayo kwihlabathi liphela, ixhanyulwa ngeendlela ezininzi. Ishishini letshokholethi lehlabathi liyimarike enkulu. Njengoko imfuno iqhubeka isanda, abavelisi bajongene noxinzelelo lokugcina imigangatho engqongqo yomgangatho kunye nokusebenza kakuhle kwemveliso.
Iyasebenzaumlinganiselo we-viscosity yetshokolethiichaphazela ukuhamba, ukufana kwengubo, kunye nobunjani beemveliso zetshokholethi, nokuba zikwiibhari, iilekese, okanye iimpahla ezifakwe i-enrobe.i-viscosity yokugquma itshokolethikunokubangela ukuba iingubo zingalingani, iziphene zemveliso, okanye ukungasebenzi kakuhle kokucubungula, okukhokelela ekwandeni kweendleko kunye nokungoneliseki kwabathengi.
Inkqubo Yokuvelisa Itshokolethi & Amanqanaba okulinganisa ukuxinana
Inkqubo yokuvelisa itshokolethi ibandakanya ukucutshungulwa kokuqala, ukurosta, ukusela, ukugaya, ukukhonkxa, ukufutha kunye nokubumba.
Ukwaleka ngetshokholethi
*
Iimbotyi zekoko ziyosiwa ngokuchanekileyo, zicolwe kakuhle, emva koko zidityaniswe nezithako ezifana neswekile kunye nomgubo wobisi.
Le nkqubo inciphisa ubungakanani bamasuntswana etshokolethi, nto leyo ebangela ukuba ubume bayo bube bushelelezi kwaye bucokiseke ngakumbi.
Ngokulawula ngokuchanekileyo ukwakheka kwebhotolo yekoko, ukufudumala kunika ukugqitywa okukhazimlayo kunye nokukhanya okugqibeleleyo.
Xa sele ithambile, itshokolethi ibunjwa ibe ziibhari, ibunjwe ibe ziipraline, okanye ifakwe phezu kwezinye iimveliso, ize ipholiswe ukuze iqine.
Inqanaba eliphambili apho itshokolethi isetyenziswa kwiimveliso ezahlukeneyo, nto leyo ephucula kakhulu ukubonakala kwayo kunye nencasa.
Inyathelo lokugqibela liqinisekisa ukuba itshokolethi igcina umgangatho wayo kuyo yonke intengiso kunye nothutho.
Ukuqina kwetshokholethi kubaluleke kuphela kwisigaba solwelo, njengoko kufuneka ibe kwimeko yokunyibilika ukuze ihambe kwaye ilinganiswe. Amanqanaba aphambili aquka:
·Utywala beCocoa (Emva kokuGcada): Emva kokucola ii-cocoa nibs kwi-cocoa liquor, i-viscosity iyavavanywa ukuze kuvavanywe iipropati zokuhamba kwezinto ezisisiseko.
· Itshokolethi Ecociweyo (Ngexesha/Emva Kokuqhotsa): Ngexesha lokuxinana, iswekile, ibhotolo yekoko, kunye nezinye izithako ziyaxutywa, nto leyo echaphazela ukuxinana. Ukulinganisa kuqinisekisa ukuba itshokolethi ithambile kwaye iyahamba.
·Itshokholethi enomsindo (Emva kobushushu)Emva kokufudumala, i-viscosity iyajongwa ukuqinisekisa ukuba itshokolethi ifanelekile ukubumba, ukugquma, okanye ukuyifaka.
Ukubaluleka kweVisci-osity IiMeasuremi-entof Ukwaleka ngetshokholethi
Ukulinganiswa kobungqindilili kudlala indima ebalulekileyo ekuvelisweni kweengubo zetshokholethi ezikumgangatho ophezulu, nto leyo echaphazela ngokuthe ngqo imbonakalo yemveliso yokugqibela, ubungqindilili, kunye nokuhambelana. Kwinkqubo yokufakela, apho umaleko wetshokholethi olulwelo ufakwa kwiindawo ezifana neenati, iibhisikithi, okanye izaliso ze-confectionery, ubungqindilili bumisela indlela oluhamba ngayo ngokulinganayo nangokutyibilikayo. Ukuba ubungqindilili buphezulu kakhulu, itshokholethi iba nkulu kwaye imelane nokuhamba, nto leyo ebangela ukugquma okungalinganiyo, ukwakheka okugqithisileyo kwiindawo ezithile, okanye ukunamathela okungaphelelanga embindini. Ngokwahlukileyo koko, ukuba ubungqindilili buphantsi kakhulu, ubungqindilili bunokuthontsiza kakhulu, nto leyo ekhokelela kwiingubo ezincinci, izinto ezilahliweyo, kunye neqokobhe elibuthathaka eliqhekeka lula.
Ngaphaya kobuhle kunye nokugubungela, i-viscosity ichaphazela ngokuthe ngqo ukusebenza kakuhle kwemveliso kunye nolawulo lweendleko. Iingubo zetshokholethi ezine-viscosity engaguqukiyo zinokuphazamisa imigca ye-enrobing ekhawulezayo, ibangele ukuvaleka komatshini, ixesha lokungasebenzi rhoqo, okanye isidingo sokulungiswa ngesandla. Ngaphezu koko, ubungakanani betshokholethi ethathwayo ngexesha le-enrobing—eyaziwa ngokuba bubunzima be-pickup—bunxulunyaniswa kakhulu ne-viscosity. Ukuphambuka okuncinci kunokutshintsha umlinganiselo we-coating-to-center, okuchaphazela kungekuphela nje ukuthungwa kunye nokuvakalelwa komlomo kodwa kunye neendleko zokulebhelisha izondlo kunye nezithako. Kwiimveliso zeprimiyamu, apho abathengi balindele ukuluma okulinganayo kunye ne-crisp snap kunye ne-silky melt, ukugcina uluhlu lwe-viscosity ekujoliswe kuyo (umz., i-1,200–2,000 mPa·s yeengubo zetshokholethi emnyama) akunakuxoxiswana. Ukulinganisa rhoqo kusetyenziswa ii-viscometers ezijikelezayo kuvumela ukulungiswa kwexesha langempela ngokulungiswa kobushushu okanye ukongezwa kwe-lecithin, ukuqinisekisa ukuphindaphinda kwebhetshi ukuya kwibhetshi.
Okokugqibela, ukulinganiswa kwe-viscosity kubalulekile ukuze imveliso ihlale ixesha elide kwaye isebenze ixesha elide. Itshokholethi yi-emulsion eyinkimbinkimbi yezinto eziqinileyo ze-cocoa, iswekile, kunye namafutha, kwaye i-viscosity engafanelekanga idla ngokubonisa iingxaki ezisisiseko ezifana nokusasazeka kakubi kwamasuntswana, ukungena komswakama, okanye iingxaki ze-crystallization yamafutha. Ngokuhamba kwexesha, ii-coating ezine-viscosity engalunganga zisengozini yokuqhakaza kwamafutha—umhlwa omhlophe obangelwa yibhotolo ye-cocoa efudukayo iye kumphezulu—okanye ukwahlukana kweoyile, zombini ezo zinto zinciphisa umgangatho weemvakalelo kunye nokuthenjwa kwabathengi. Ngokudibanisa uvavanyo lwe-viscosity kwiiprotokholi zokuqinisekisa umgangatho, abavelisi banokuqikelela kwaye bathintele ezi ziphene, banikeze ii-coating ezihlala zikhazimla, zigudile, kwaye zikhululekile ukusuka kumgca wemveliso ukuya kwishelufu ye-pantry. Ngokwenyani, i-viscosity ayisiyonto nje ebonakalayo—ngumgcini wobuhle be-coating yetshokholethi.
I-Rheology yeChocolate: Izinto ezichaphazela ukuxinana
I-rheology yetshokholethiyisayensi yendlela itshokolethi ehamba ngayo kwaye iziphatha ngayo phantsi kweemeko zokucutshungulwa. Zininzi izinto ezichaphazelai-viscosity yesiraphu yetshokolethikwayei-viscosity yotywala betshokolethi, kuquka:
·Umxholo webhotolo yeCocoa: Amanqanaba aphezulu anciphisa i-viscosity, aphucula ukuhamba kwamanzi kodwa anokuchaphazela ukuthungwa kwawo.
·Ubungakanani beParticle: Amasuntswana amancinci andisa uburhabaxa, nto leyo efuna ulawulo oluchanekileyo ngexesha lokucocwa.
·UbushushuUkuguquguquka kutshintsha iimpawu zokuhamba kwamanzi, nto leyo ebangela ukuba kubekho ukubekwa kweliso elichanekileyo lobushushu.
·Izinga lokuchebaItshokolethi ibonisa indlela yokuziphatha engeyiyo eyeNewtonian, apho i-viscosity itshintsha phantsi kweemeko ezahlukeneyo zokucheba.
·Umxholo wobumanzi: Nokuba amanzi amancinci anokunyusa kakhulu ukuxinana kwamanzi.
·IzihlanganisiIzithako ezifana ne-lecithin ziguqula iipropati zokuhamba kwamanzi, zifuna ukubekwa esweni rhoqo.
A isixhobo sokulinganisa i-viscosityeyenzelwe ukuqokelelwa kwedatha ngexesha langempela iqinisekisa ukuba ezi zinto ziguquguqukayo zilawulwa ngokufanelekileyo, zigcina zisebenza kakuhlei-viscosity yetshokolethikuyo yonke imveliso.

I-viscometer isebenzisa i-conical sensor ejikeleza kwi-frequency ethile kwicala layo le-axial. Njengoko itshokolethi ihamba phezu kwe-sensor, iyawusika ulwelo, kwaye ukulahleka kwamandla kubalwa ukuze kuchongwe i-viscosity. Le ndlela esekelwe ekungcangcazeleni isusa iindawo ezihambayo, izitywino, okanye iibheringi, iqinisekisa ukuqina kunye nokugcinwa okuncinci. Isekethe ye-elektroniki iguqula ukulahleka kwamandla kube kukufundwa kwe-viscosity echanekileyo, eboniswa ngexesha langempela ukuze kulungiswe inkqubo ngoko nangoko. Olu yilo lusebenza ngokukodwa ekujongenii-viscosity yokugquma itshokolethi, i-viscosity yesiraphu yetshokolethikunyei-viscosity yotywala betshokolethi.
