Ukufudumala linyathelo lokugqibela kwimveliso kwaye kunempembelelo enkulu kumava etshokolethi yokugqibela kubathengi.Ngaba ukhe waba nebha yetshokolethi eyayibhityile kwaye yayinefilimu emhlophe e-opaque ngaphandle?Mhlawumbi ukucaphuka akwenziwanga kakuhle okanye kukho into engalunganga malunga nezithako
Ukuqonda ingcambu yale ngxaki, kufuneka ukwazi kancinci malunga namafutha kwitshokolethi.Ibhotela ye-cocoa i-akhawunti ye-48% -57% yobunzima beembotyi ze-cocoa.Yinto eyenza itshokolethi inganyibiliki esandleni (iqinile kwiqondo lobushushu begumbi) inyibilika kuphela emlonyeni (iqala ukunyibilika kubushushu bomzimba).Ukubeka iqhekeza letshokholethi elulwimini lwakho kwaye uyive inyibilika kancinane emlonyeni wakho yenye yezona mpawu zihendayo zetshokholethi, yonke into ebulela kwibhotolo yekoko.
Ibhotela ye-cocoa i-polymorphic, oku kuthetha ukuba, phantsi kweemeko ezahlukeneyo zokuqiniswa, zenza iintlobo ezahlukeneyo zeekristale, ezinokuthi zizinzile okanye zizinzile.Iikristale ezizinzileyo zipakishwe ngokusondeleyo kwaye zineendawo eziphezulu zokunyibilika kuneekristale ezingazinzanga.Kufuneka siyicaphukise ngokufanelekileyo itshokolethi ukuze xa uyingcamla ihlale igudile ngaphandle kwaye ithambe ngaphakathi njengoko siyenzile.
Ibhotela ye-cocoa i-polymorph, echongwa njenge-5 yeefom ze-crystal ezahlukeneyo ze-1, y (i-Gamma) uhlobo, olwenziwa ngokupholisa ngokukhawuleza kwiqondo lokushisa eliphantsi.Yifomu yekristale engazinzanga ngokugqithisileyo, kwaye indawo yayo yokunyibilika imalunga ne-17°C2, uhlobo (Alpha), uhlobo lwe-y lunokuvela ngokukhawuleza lube kuhlobo, indawo yokunyibilika kwayo iphakathi kwe-21 ~ 24°C, kodwa itshintsha kancinane ibe yi-B. ' crystal form 3, B' (Beta-prime), ine-B'1 kunye ne-B'2 iifom ezimbini zekristale, indawo yokunyibilika ye-B'2 ye-crystal form iphakathi kwe-27 kunye ne-29°C.
4. Ifom ye-crystal ye-Bi, indawo yayo yokunyibilika malunga ne-33C.UFomu B' utshintsha kancinci abe ku-B
IFomu B yeyona fomu yekristale izinzile, kwaye indawo yayo yokunyibilika imalunga nama-34 ~ 35°C.
Ukongeza, abanye abantu bakholelwa ukuba iikristale cocoa ibhotolo babe 6 iifom crystal, imelwe amanani 1 ~ 6, kunye namanqaku ukunyibilika ezi 6 iintlobo: 173 23 3% 25 5% 265% 33 836.4 °.Iifom ze-crystal 1 ukuya kwi-4 zifana ngokusisiseko ne-1 ukuya kwi-4 kwiifom zekristali ezingentla apha, kwaye zonke ziifom zekristale ezingazinzanga.Umahluko kukuba i-crystal yesihlanu ifom ye-B iyona fom ye-crystal ezinzile kunye nokulawulwa kweqondo lokushisa eliqhelekileyo.iya kutshintsha kancinane ibe yikristale yesithandathu ezinzileyo ngakumbi.
I-Tempering kukuqinisekisa ukuba ibhotela ye-cocoa kunye ne-cocoa ibhotela-efana nefom ye-crystal ezinzileyo, kwaye emva koko uyipholise ngokuchanekileyo ukwenzela ukuba itshokolethi ibe ne-luster enhle kwaye akukho mcimbi omhlophe ixesha elide.
Ngokuqhelekileyo indlela yokutshisa itshokolethi iquka la manyathelo alandelayo
1. Nyibilikisa itshokolethi ngokupheleleyo
2. Ukupholisa kwindawo yobushushu becrystallization
3. Ukuvelisa icrystallization
4. Nyibilikisa iikristale ezingazinzanga

Kwinqanaba lobushushu, itshokolethi iyafudunyezwa, ipholile kwaye iphinde ifudunyezwe ngobunono kwiqondo lobushushu elichanekileyo ukuze ufumane iikristale ezizinzileyo zebhotolo yekoko.Ngale ndlela, unokufumana inkangeleko egudileyo kwaye ecwebezelayo xa iqina, kwaye umlomo ulungile, kwaye usenako ukuva isandi esimnandi xa uqhekeza ibha yetshokolethi.
Kwimveliso yokwenyani, iqondo lobushushu letshokholethi esulungekisiweyo lihlala lingaphezulu kwama-45, kwaye iqondo lobushushu letshokholethi ligcinwe lishushu kwitanki yokugquma liphakathi kwama-40 nama-45, kwaye akukho crystallization yawo nawaphi na amanqatha.Ke ngoko, inqanaba lokuqala lobushushu kukususa ubushushu obubuthathaka obuchaphazela i-crystallization of fat, oko kukuthi, ukupholisa ubunzima betshokholethi ukusuka kuma-40 ukuya kuma-50 ukuya kuma-32 ngokupholisa.Kwinqanaba lesibini lokulawulwa kweqondo lokushisa, izinto ziqhubeka zipholile ukusuka kwi-32 ° ukuya malunga ne-27 ° C, kwaye ioli iqala ukwenza i-B crystal form ezinzileyo kunye nefom ye-crystal B engazinzanga. ukulawulwa kweqondo lokushisa, eyaziwa ngokuba Kwinqanaba lokubuyisela ubushushu, ubushushu bezinto eziphathekayo bukhuphuka ukusuka kwi-27 ukuya kwi-30 ~ 32. Injongo yokubuyisela kukunyibilikisa ifom ye-crystal ye-B engazinzanga ngokuphindaphindiweyo ngokufudumeza, ukushiya ifom ye-crystal ye-B ezinzile.
Ubushushu bunokulungiswa ngesandla, kodwa ubushushu kufuneka buchaneke.Ukukhethaumatshini wokuthambisa itshokolethielawula ngokuchanekileyo iqondo lobushushu kumahluko obushushu obungaphantsi kwe ± 0.2 inokukunceda kakuhle kakhulu.Ukushisa kweetshokholethi ezahlukeneyo nako akuhambelani ngokupheleleyo:
