Le ndlela isisiseko seenkqubo zanamhlanje zokukhupha i-cocoa ngokuzenzekelayo apho ukugcina ukufana kwemveliso kunye nokwandisa umgangatho wencasa kubaluleke kakhulu.
Ukunciphisa iiCompounds ezingenancasa kusetyenziswa umlinganiselo woxinano
Ukulinganisa uxinano oluphakathi kubaluleke kakhulu ekufumaneni ngexesha langempela iimeko ezikhuthaza ukwakheka kwencasa engeyiyo kwinkqubo yokukhupha i-cocoa. Ngexesha lokubilisa kunye nokurosta, iikhompawundi ezithile ze-organic eziguquguqukayo—ezifana ne-(-)-geosmin kunye ne-3-methyl-1H-indole—zinokungenisa amanqaku amdaka okanye anomsi, nto leyo ethoba ubunzulu bevumba le-cocoa kunye nomgangatho uphela. Ezi ncasa zingaqhelekanga zihlala zivela xa ubuninzi bemveliso yokubilisa budlula okanye bungaphantsi kobubanzi obufanelekileyo, okanye xa izinto eziguquguqukayo zokurosta (ubushushu, ixesha) ziphambuka kwiindawo ezimiselweyo.
Ngokuhlala ujonga uxinano lwe-cocoa slurry kunye notywala besebenzisa izixhobo ezingaphakathi, njengee-vibronic density sensors zeLonnmeter, abavelisi bafumana ulwazi olukhawulezileyo malunga notshintsho oluhambelana nokunyibilika kwe-flavour compound kunye nokuguquka kwemveliso. Umzekelo, ukuphambuka okungalindelekanga kwi-density curves ezilindelekileyo kunokubonisa ukubila okungaqhelekanga, okuhlala kuhambelana neencopho kwi-volatious off-flavour compounds. Oku kwenza ukuba kulungiswe ngokukhawuleza—njengokulungisa ixesha lokubila, ubushushu, okanye ukushukunyiswa—ngaphambi kokuba ii-off-flavours zibonakale.
Uxinano lusebenza njengommeli wokulandelela inkqubela yokubilisa kunye notshintsho olubangelwa kukubosa kwiindlela zokukhupha i-cocoa. Impendulo ephezulu evela kwiisensors ezikwi-inline ibonisa ukuqokelelwa okungafunekiyo kweemveliso zokubilisa, kubandakanya ii-asidi kunye nee-aldehydes, ezithi, ukuba azijongwanga, zonakalise imveliso ye-cocoa liqueur kunye nomgangatho wencasa. Umzekelo, ukunyuka okuncinci koxinano kunokutyhila ukufuma okungaphelelanga komswakama ngexesha lokubilisa okanye ukunyibilika kakhulu kwe-flavour antagonists. Kwiimeko ezinjalo, ulawulo oluzenzekelayo lunokuguqula imijikelo yokubilisa, luphucule amanqanaba okomisa, okanye lulinganisele kwakhona amaqondo obushushu enkqubo-ukuphucula ukukhupha incasa ye-cocoa kunye nokunciphisa umngcipheko wamanqaku anomsi okanye anomngundo.
Ngokudibanisa idatha yoxinano oluphakathi kunye neenkqubo zokuzenzekelayo kwezityalo, iinjineli zeenkqubo ziseka ulawulo oluvaliweyo oluphucula iindlela zokukhupha i-cocoa. Ukulinganisa okuphakathi kubonelela ngempendulo ekhawulezileyo yokulungisa izinto ezahlukeneyo kumanyathelo abalulekileyo: ukubilisa, ukwahlula, ukurosta, kunye nokupholisa. Oku kuxhasa ukumisela isiphelo sokukhupha, okuvumela abaqhubi ukuba bamise ngokuchanekileyo inkqubo xa iiprofayili zencasa ezifanelekileyo zifezekiswa kwaye ukuveliswa kwencasa engaphandle kuncitshisiwe—ukuphucula ulawulo lokuqina kwevumba kwiimveliso ze-cocoa ngelixa kunciphisa ukushukuma kwencasa kunye nokuguquguquka kwebhetshi.

Ukwenziwa kwe-alkalization ye-cocoa mass kutshintsha i-pH, okuchaphazela zombini indawo engabonakaliyo neguquguqukayo. Ukwanda kwe-alkaline kudla ngokukhawulezisa umsebenzi weMaillard ngexesha lokurosta okulandelayo, kuphakamisa ukwakheka kwe-pyrazine kunye ne-ester—okubalulekileyo kwiinowuthi zetshokholethi ezirostiweyo nezineziqhamo. Nangona kunjalo, ukwenziwa kwe-alkalization okunamandla kunokunciphisa ii-flavanols, i-methylxanthines, kunye nezinye ii-esters ezisebenzisa ivumba elimnandi, okunokuthi kunciphise ukuhluka kwetshokholethi.
Amanqanaba okunyibilika kweekhompawundi zencasa kwimveliso ye-cocoa liqueur achatshazelwa lolu tshintsho. Ukwakheka okuphezulu kwe-pyrazine kuhambelana nokukhululwa kwevumba ngokukhawuleza, kodwa i-alkaliization egqithisileyo ibeka emngciphekweni izinto ezincasa ezibuthathaka. Izifundo ezisebenzisa i-alkaliization encediswa yi-microwave zibonisa isivuno esiphezulu se-pyrazine kunye nobunzima bevumba—okubonisa ukuba inkqubo yokwenza i-cocoa liqueur inenzuzo kwiindlela ze-alkaliization ezenzelwe wena kwiinjongo ezahlukeneyo zemveliso.
Ukusetyenziswa ngokufanelekileyo kwe-cocoa yokulinganisa i-aroma intensity, njengakwiinkqubo zeLonnmeter, kuvumela ukulinganiswa kwexesha langempela kwezinto eziphilayo eziguquguqukayo kunye nokufuma, kuxhasa ulawulo olucwangcisiweyo lwamandla e-aroma ngexesha le-alkalization, roasting, kunye ne-conching. Umzekelo, ii-sensors zinokuqinisekisa xa ubuninzi be-ester kunye ne-pyrazine bufikelela kwiincopho zazo zokunyibilika, nto leyo ebonisa ukugqitywa kokuphela kokukhupha kwi-cocoa processing.
