Isithombe: I-Yeast Flocculation Study

Isithombe sibonisa umbono onemininingwane eminingi, weleveli enkulu yebhika laselabhorethri eliqukethe isampula ye-Belgian Abbey Ale phakathi kweyeast flocculation. Isihloko sithwetshulwe ngokugqama okubukhali, kuyilapho ingemuva lihlala lifiphele kancane, okuvumela ukunaka kombukeli ukuthi kuhlale ngokuqondile oketshezini olunombala osagolide kanye nezendlalelo zakhona ezihlukile. Ukwakheka kungokwesayensi nobuciko, kulinganisa ukunemba kobuchwepheshe nobuhle obubonakalayo.

Enkabeni yohlaka kuhlezi ibhakha eliyisilinda elicacile elenziwe ngengilazi yaselabhorethri ebushelelezi, ebonisa ngale. Udebe lwayo lugobela ngaphandle ngobumnene, lubamba ukukhanya okucashile okugcizelela ukucaca nobumsulwa bento. Ngokungafani nezingilazi zokulinganisa ezimakiwe, lo mkhumbi uncane ngamabomu, awunazo izikali eziphazamisayo noma amalebula, ogcizelela ukugxila okubukwayo kubhiya ngokwawo. Ingilazi ihlezi phezu kwekhawunta ehlanzekile, ephaphathekile, indawo ekhanyayo enanela ngobuqili amathoni a-amber oketshezi ngaphakathi. Indawo ezungeze ubhekhayi ingeyesimanje futhi yomtholampilo—amacebo emishini yelebhu efiphele namashalofu ayabonakala ngemuva okugxilwe kancane, nokho ahlehlela ekufinyezweni, okuphakamisa ubunyumba nokuhleleka ngaphandle kokudonsela ukunaka kude ngaphambili.

Ngaphakathi kwebhika, ubhiya uzethula ngokwezigaba eziveza amandla emvelo okuvutshelwa kanye nokuziphatha kweyeast. Ingxenye engaphezulu yoketshezi ikhazimula ngombala we-amber-golden okhanyayo, okhazimulayo kodwa ofudumele, okhumbula ukukhanya kwelanga okudlula uju. Alengiswe ngaphakathi kwalolu ungqimba, amabhamuza amancane esikhutha akhuphukela phezulu kancane kancane, enze amandla athambile anikeza amandla nokunyakaza. Amabhamuza abamba ukukhanya, acwebezele njengamaphoyinti amancane esiliva ngaphakathi komzimba wenhlaka ejulile.

Ngaphansi nje kobuso kukhona igwebu elincanyana, eliphaphathekile. Lo mqhele onegwebu awulona ihaba noma waseshashalazini, kodwa unesizotha futhi uhlangene, uphakamisa ukuthululwa okulawulwayo okulungele ukucwaninga kwaselabhorethri kunokuphuza okuvamile. Umbala wayo omhlophe nowendlovu uqhathanisa kahle nokujula kukabhiya okusagolide, wenze umugqa othambile ohlukanisayo phakathi koketshezi nomoya.

Ingxenye engezansi ye-beaker ixoxa indaba yobuchwepheshe nethakazelisayo kakhulu. Phansi, kunqwabelene ungqimba oluminyene lwenhlabathi, lwakha isisekelo esibonakala ngokucacile sezinhlayiya zemvubelo ezintantayo. Intlenga iwugqinsi futhi inokhilimu ngokokwakheka, umbala wayo osuka ku-beige-to-tan udala umehluko omangalisayo noketshezi lwenhlaka olukhanyayo olungenhla. Lesi sendlalelo esiyisisekelo sibonisa isenzakalo se-yeast flocculation ngokucacile okuphawulekayo: amaseli ake alenga oketshezini abophene ndawonye, anqwabelene, futhi azinzile, ashiya ngemva kwesigaba soketshezi esikhula ngokucaca kancane njengoba sikhuphukela phezulu kubhekha.

Ukushintsha phakathi kwezendlalelo kuhamba kancane kunokuba kungazelelwe. Ngaphezulu nje kwenhlabathi, ubhiya unenkungu kancane, nezinhlayiya ezibonakalayo zisalokhu zincipha kancane. Uma ukhuphuka ubheke phezulu, ubungungu buqala ukucaca, kuze kube yilapho ingxenye yesithathu engaphezulu yoketshezi icwebezela obala, okuwukubonakaliswa okucacile kwenqubo yokudilika kwenhlabathi. Le gradient yokucaca—kusuka ku-opaque esisekelweni, kuya kokucwebezelayo maphakathi, kuya ku-crystalline phezulu—isebenza njengesibonelo sencwadi yokufunda yesayensi yotshwala ethathwe ngesikhathi sangempela.

Ukukhanyisa kuthambile ngamabomu futhi kwasakazwa, kungena kusuka kumthombo ongekho ikhamera, mhlawumbe iwindi laselabhorethri noma into engaphezulu. Ibeka amaphuzu avelele acashile emaphethelweni engilazi agobile futhi iveza ukucwebezela kwe-amber koketshezi, kuyilapho futhi idala izithunzi ezithambile ezigqamisa ukujula nokuminyana kwenhlabathi. Ukuhlangana kokukhanya nesithunzi kugcizelela ukuthungwa kwegwebu, amabhamuza, nentlenga, okuboleka isithombe kokubili ubukhulu kanye nokuthinta.

Isimo sengqondo esiphelele sesithombe singowophenyo lwesayensi nokunemba, okuthonywa ubuhle bezinto eziphilayo zenqubo yokuphisa. Lesi akusona isithombe se-ale njengesiphuzo esiphelile esilungele ukusetshenziswa, kodwa njengesihloko sokuhlaziya—iphuzu ledatha ophenyweni olubanzi lokuziphatha kwemvubelo, i-fermentation kinetics, kanye nobuciko bokuphisa i-abbey yaseBelgium. Idlulisa inhlonipho yesiko kuyilapho igcizelela ukuqina kocwaningo lwelabhorethri yesimanje, ihlanganisa amagugu obuciko nesayensi yobuciko.
