Isizinda se-Ultrasonic se-Caffeine

Ukusebenzisa i-ultrasonics kuyindlela ephumelelayo yokukhipha i-caffeine nezinye izakhi ezisebenzayo ezivela ekhofi. Amadivaysi ama-ultrasonic anamandla asiza inqubo yesikhamo ngenkathi ukwandisa isivuno nokunciphisa isikhathi sokucubungula.
Ikhofi - eyenziwe ngamabhontshisi wekhofi othosiwe – kuyinto isiphuzo esidumile kakhulu esidliwa emhlabeni wonke. Ngaphandle komthelela wayo we-vitalizing uma udliwe njengesiphuzo esiphuthumayo, izinhlanganisela zekhofi zithandekayo ekudleni, imithi (isib. Ekubuyiseni ubuhlungu) futhi Industry Cosmetic njengoba isetshenzisiwe njengezithasiselo eziwusizo emikhiqizweni ehlukahlukene. Lokhu kusebenza ikakhulukazi kwe-caffeine (1,3,7-trimethylxanthine) kanye nama-antioxidants, awaziwayo ngemiphumela emihle empilweni yomuntu. Ikhofi iqukethe, phakathi kwezinye, i-phenolic diterpenes efana ne-cafestol ne-kahweol, ne-ascorbic acid, eyaziwa ngomsebenzi wabo wokuvimbela i-antioxidative. Ucwaningo lwe-epidemiological lubonisa ukuthi izithako zekhofi zingase zibe nomthelela wokuvimbela izifo eziningana ezingapheli, kuhlanganise nohlobo lwesifo sikashukela, uhlobo lwesifo sikashukela, isifo se-Alzheimer, isifo sika-Parkinson, nesifo sesibindi njenge-cirrhosis ne-hepatocellular carcinoma.
I-Ultrasonics iyithuluzi eyaziwa futhi eliqinisekisiwe lezinhlelo eziningi ezahlukene ezimbonini ezihlukahlukene. Isicelo esiphumelele kakhulu yi-ultrasonic Ukukhipha. Ngaleyo ndlela, i-ultrasonic cavitation imiphumela kumakhalekhukhwini weselula okubangela ukuphazanyiswa kwamangqamuzana nokukhululwa kwendaba ye-intracellular.
Nge-sonication, i-caffeine namanye ama-coffee compounds angasuswa kahle.

I-High Power Ultrasound

Ukuqinisekisa ukuqonda okulula kakhudlwana kwenqubo ye-ultrasound eyasizwa yesikhumba, umphumela we-ultrasound kusetshenziswa uketshezi kufanele uchazwe.
I-Ultrasound – esetshenziselwa uketshezi – kubangela imiphumela yendawo embi kakhulu. Lapho ukuphuza utshwala ngokweqile, amagagasi omsindo asakaze emithonjeni yamanzi ashukumisela ukushintsha ukucindezela okuphezulu (ukucindezela) nokujikeleza okuncane (ukungavamile), namazinga kuye ngokuthi imvamisa. Ngesikhathi umjikelezo ophansi ocindezelayo, amagagasi aphakeme kakhulu e-ultrasonic enza ama-bubbles amancane avulekile noma aphuma emanzini. Lapho ama-bubbles athola umthamo lapho bengakwazi khona ukuwuthola amandla, awela phansi ngesihluku phakathi nomjikelezo ophezulu wokucindezela. Lesi simo sibizwa cavitation. Phakathi nokushisa okuphezulu kakhulu (cishe 5,000K) kanye nezingcindezi (cishe 2,000atm) kufinyelelwe endaweni yangakini. I-implosion ye-bubble cavitation nayo ibangele ama-jets ahlanzekile angama-280m / s velocity. [Suslick 1998] Ngalokhu kukhululeka kwe-sonolysis kwenzeka, izindonga zeseli ziphazanyiswa, futhi impahla ye-intracellular ikhishwa.

I-ultrasonically cavitation ekhiqizwa uphondo lwe-UIP1500hd - i-1.5kW idivayisi ye-ultrasonic. Ukuze kubonakale kangcono, uketshezi lukhanyisiwe ngokukhanya okwesibhakabhaka kusuka phansi kwekholomu yeglasi.

I-cavitation ye-Ultrasonic eketshezi

Isizinda se-ultrasonically esisize siyindlela engabizi, elula futhi ephumelelayo eqhathaniswa namasu ajwayelekile okukhipha. Izinzuzo eziyinhloko ze-ultrasound eziqinile-uketshezi lwamanzi zihlanganisa ukwanda kwezitshalo zokukhiqiza kanye ne-kinetics esheshayo. Isizinda se-Ultrasonic yisindlela esetshenziswa ngaso sonke isikhathi ukukhishwa kwezinto zokutshala ezisebenzisa izixazululo zamanzi futhi kuboniswe inqubo yesikhumba esheshayo futhi ephelele uma kuqhathaniswa nezindlela zendabuko ngoba indawo ephakathi kwesigaba esiqinile nesisetshenziselwa uketshezi ikhulu kakhulu ngenxa yokuphazamiseka kweseli futhi i-particle dispersion.
Ngokusetshenziswa kwe-sonication futhi ukushisa okusebenzayo kungancishiswa, okuvumela ukukhishwa kwezingxenye zokushisa ezibucayi. Uma kuqhathaniswa namanye amasu okukhishwa kwendabuko njengesizinda sokusizwa nge-microwave, amadivaysi e-ultrasound ashibhile futhi ukusebenza kwawo kulula. Ngaphezu kwalokho, isizinda esisizwa nge-ultrasonically singasetshenziswa nanoma iyiphi i-solvent, njengesizinda seSoxhlet, ngokukhipha izinhlobo eziningi zemvelo. [Wang et al. 2006] Uma kunesidingo, izinhlelo zokuqhuma izimboni zezinqubo zezimboni zikhona.
Inzuzo enkulu ye-ultrasonics iyinethonya ekubaluleke kakhulu kwemigomo yokucubungula: amplitude, isikhathi, izinga lokushisa, ingcindezi, kanye ne-viscosity. Ngakho-ke, inqubo yokukhipha ingahle iqinisekiswe ukuthi isakhiwo samacwecwe asilimazi.

Extraction Ultrasonic of Coffee Compounds

Isizinda esivunyelwe i-Ultrasound kuyindlela evamile esebenzisa ukuhlukanisa izinto eziphilayo ezivela emthini wesitshalo [Dong et al. 2010]. Ngokuphathelene nobhontshisi wekhofi, amakhemikhali e-caffeine kanye ne-antioxidant phenolic angase abe amakhemikhali ayigugu kakhulu ngenxa yezicelo zabo ezibanzi embonini ye-pharma kanye nokudla. Kodwa futhi i-flavonoids, i-chlorogenic acid ne-protocatechuic acid yiziqhumane ezisetshenziswa njengezithasiselo.
Ukusebenzisa izindlela zendabuko yesikhumba njenge-liquide-liquid liquid in solvents, ngokuvamile ukukhishwa kwesikhumba kwanda ngokushisa kwamazinga okushisa. Lokhu kubangela ukulimala kanye nokulahlekelwa kwekhwalithi yokukhishwa njengamazinga okushisa kuthinta ukuzinza kwama-phenolic compounds.
I-ultrasound-eyasizwa ngokuqinile-okuketshezi ketshezi iye yaboniswa njengendlela ephumelelayo yokugcina isikhashana. Amandla amakhulu e-ultrasonic ahlinzeka amandla afunekayo ukuze enze isizinda, ngakho-ke kuyadingeka ukuthi kungadingeki noma kungabi namancivents. Ukushisa kungenziwa ukulawulwa kahle njengoba i-bathed sonicated noma flow flow cell ingenziwa kahle (noma ukufutheka uma kunesidingo). Ngenxa yezinqubo zokukhipha nge-solvents, i-Hielscher Ultrasonics inikeza izinhlelo ze-ultrasonic eziqinisekisiwe ze-ATEX ne-FM eziqinisekisiwe.
Ngenxa yamandla amakhulu okuphuma kwe-ultrasound, futhi i-coffee already ground (i-coffee waste) isengumcebo ocebile ocebileyo. Njengoba i-coffee waste material ishibhile futhi itholakala ngesamba esikhulu, kuyinto ebonakalayo ebonakalayo yokufakelwa kwamakhemikhali asebenzayo asele. Nakuba okuqukethwe kwe-caffeine nezinye izingxenye zekhofi edoti kuncane kunomshini wekhofi ongasetshenzisiwe, isamba esikhulu sisalokhu futhi sincane. Ukuze ukhulule lezi zinhlanganisela kusuka emhlabathini wekhofi, ithonya eliphelele emiphakathini yokucubungula ibaluleke kakhulu. I-high-power ultrasound iyakwazi ukukhipha inani eliphakeme lehlanganisiwe esebenzayo ngaphakathi kwesikhathi esifushane sokucubungula.

I-Ultrasonication iyindlela ephumelelayo yokukhipha ama-active, ama-flavour nezinye izingxenye ze-intracellular ezisuka kumangqamuzana wemifino.

I-caffeine extraction

I-caffeine ingathiwa i-stimulant evame ukusetshenziswa kakhulu. Njengoba i-caffeine ingadli kuphela ikhofi yokuphuza, i-caffeine extract isetshenziswa embonini ukuphatha omunye umkhiqizo nge-caffeine njengokwengeza. Ngakho-ke kuyoba khona ukudala ikhofi enamandla noma ukwakha iziphuzo ezithambile (isib. Cola), iziphuzo zamandla noma ezinye ukudla (isib. Ushokoledi).
Kodwa i-caffeine ayisebenzisi nje kuphela njengokwengeza ku- Ukudla ukukhiqizwa, kuyisakhi esibalulekile esisebenzayo emithi yokwelapha kanye. Isicelo esivamile sokukhishwa kwe-caffeine sib. Ukuhlanganiswa kwezidakamizwa ezikhanda ikhanda kanye ne-migraine noma ekunciphiseni ubuhlungu.
Ukukhipha i-caffeine, i-alkaloid esemqoka ekhofi, i-ultrasonication iyindlela efanelekayo. UWang nozakwabo [Wang et al. 2011] wathola ukuthi kudingekile isikhathi esifushane sokususa ukuze kufinyeleleke esimweni esigcwele, uma kusetshenziswa i-ultrasonication. Lokhu kusho ukuthi i-ultrasound inqubo ephumelelayo kakhulu yokugcina i-caffeine.

Amakhemikhali aphunga namnandi

Amakhemikhali efihlekile wekhofi yingxenye ewusizo kakhulu yebhontshisi eyosiwe futhi unikeza ikhofi yayo iphunga eliyingqayizivele nephunga elimnandi. Ikhwalithi yekhofi enomswakama ingathuthukiswa kakhulu ngokufaka amafutha wekhofi ephosiwe emakhaleni ekhofi.
Ucwaningo lokuqhathaniswa, ukuhlola ukukhishwa kwamakhemikhali e-phenolic kusuka ku-strawberries, kubonise ukuthi isizinda se-ultrasonic sibangela ukungcola okuncane kwezimo ze-phenolics futhi inqubo yokucubungula ngokushesha kakhulu uma kuqhathaniswa nezinye izindlela zokufakelwa kubandakanya indlela eqinile-amanzi, amanzi aphansi nokusizwa nge-microwave. [Herrera et al. 2005]
Ukufunda kukaWang kanye nozakwabo [Wang et al. 2011] kubonisa ukuthi imvamisa ephansi, amandla amakhulu e-ultrasound asebenza ngokuphumelelayo ngokukhipha ama-flavour yekhofi. Ikakhulukazi ye-4-Tridecanone ne-2-Methoxy-3-Methylpyrazine, bathola isizinda se-ultrasonic esilula kakhulu futhi sisebenzisekayo ukuthola izithelo eziphakeme kakhulu. Ngaphezu kwalokho, kuboniswa ukuthi izinga lokushisa kumele lilawulwe njengezingxenye ze-flavour components zivutha kakhulu emazingeni okushisa aphezulu. Bafinyelele imiphumela emihle yokukhipha izinga lokushisa phakathi kwama-35 ~ 65 ° C ngaphansi kwe-irradiation encane kakhulu yesikhathi esifushane.

Isizinda se-tea

Imiphumela etholakala yi-ultrasonically isizinda esisizwa nayo iyakwazi ukukhishwa kwamathisimu wetiye (isib. Amaqabunga amahlamvu aluhlaza). Ucwaningo olwenziwa ngu-Xia et al. wabonisa okuqukethwe okunamandla kakhulu kwetiyi polyphenols, i-amino acid ne-caffeine ekuthwaleni i-tea infusions nge-ultrasonically kunelabo abatholwa yi-extraction evamile. Lokhu kubangela imiphumela ethuthukisiwe ngesikhathi sokuhlolwa kwe-organoleptic okwenzeka: ikhwalithi yokuzwa itiye ukumnika nge-ultrasonic-kusiza isizinda kwakungcono kunokwesekwa kwetiyi ngokukhipha okujwayelekile. [Xia et al. 2005]

Abakwa-Hielscher ultrasonicators, isib. UP200S (esithombeni), baphumelela kakhulu ekukhishwe kwezindaba zangaphakathi.
