Ikhofi ibangela ukwanda kwesisu esiswini, kodwa kunezindlela zokunciphisa
Ezinye izifundo ziye zaxhumanisa ikhofi ukusetshenziswa kwezinye izinzuzo zezempilo. Noma kunjalo, ikhofi ayithandi njalo izinhlelo zokugaya abantu. Eqinisweni, kungabangela izimpawu ezifana nokuphuza noma ukuphuza i-dyspepsia, i- acid indigestion , ne- reflux . Ngokuvamile, kungenxa yokuthi ikhofi ibangela ukwanda kwesisu esiswini. Lokhu kushiya abantu abajabulela ikhofi befuna izixazululo kule nkinga.
Nakhu lapho abacwaningi abangene khona ukufuna izimpendulo. Ososayensi baye balahleka ukuthi yiziphi izinhlanganisela ezitholakalayo ekhofi nokuthi zingahle zilungiswe ukuze zenze ikhefu elizwakalayo. Kungenzeka yini ukuphuza izinhlobo ezithile zekhofi ezinciphise ezinye zezinkinga zesisu ezithandwa ngabathandi bekhofi?
I-Coffee Acid Ephansi
Kule ngqungquthela, ikhofi ephansi ye-asidi ibhekisela kumazinga e-pH-aphansi amazinga e-pH ayama-acidic futhi aphakeme kakhulu ayisisekelo. Ukuqothula ubhontshisi wekhofi kuveza ikhofi engaphansi kwe-acidity kanye nokuphuza okubandayo futhi ihlinzeka ngalomphumela ngoba kunamakhemikhali ambalwa anikezwa ikhofi uma kubanda kakhulu.
Izinhlobo ezithile zekhofi nazo zisebenza ngokweqile ngokweqile, okungaba umphumela wokukhulelwa endaweni ephansi noma ukusebenzisa izindlela ezithile zokumisa. Ikhofi ye-asidi engezansi itholakala kuma-flavour ahlukahlukene kanye nezinketho zokugcoba.
Abanye abantu bangase bajabulele ukunambitheka kwekhofi ngendlela ephansi ye-asidi, njengoba ijwayele ukuba ishelele futhi ibe namandla kunekhofi elinama-asidi aphezulu.
Abanye bangaphuthelwa yiziphi izifundisi ezichaza ngokuthi "ukukhanya" kohlobo lwezinga le-pH langokwemvelo. Kodwa-ke, akunakwenzeka ukuthi yi-acid yangempela ekhofi eyenza ukuthi isisu sithukuthele. Ikhofi inokuqukethwe okuphansi kwe-asidi, ngokwesilinganiso, kunokuba, isibonelo, i- tomato juice nejusi le-orange .
Kungenzeka ukuthi akukho ukulimala ekuzameni ukubona ukuthi ikhofi ephansi e-asidi iyanciphisa izimpawu. Noma kunjalo, abukho ubufakazi obuhle bokuthi yi-asidi yangempela ukuthi abantu abaningi bathola inkinga ngokuphuza ikhofi.
I-Component Coffee Ewusizo Ebizwa ngokuthi i-N-methylpyridinium
Ingxenye yamakhemikhali okuthiwa yi-N-methylpyridinium (i-NMP) ingahlinzeka ngeminye imiklamo endleleni yokwenza ikhofi engasilethi kahle ngesisu. Ezinye izifundo zithole ukuthi ikhofi equkethe ukuphakama okuphezulu kwe-NMP ibangela ukuthi i-acid engaphansi kwesibindi ifihlwe, okusho ukuthi kunamanzi amancane esiswini okuletha izimpawu zokuphuza.
Lokhu kuphakamisa umbuzo: kungani singasebenzisi i-NMP njengokwelashwa ukwehlisa isisu se-esiswini? Iphuma, akulona lokho okulula. Ukubeka i-NMP ilungelo phezulu kwamangqamuzana wesisu akuzange kube nomthelela ofanayo, ngakho-ke kucacile ukuthi kuningi endabeni nokuthi ama-compounds ekhofi asebenza ndawonye ngendlela eyinkimbinkimbi yokuthonya ukukhululwa kwama-acast gastric.
I-Real Culprit Ingaba Ngama-Chlorogenic Acids
Ezinye izinhlanganisela zekhofi ezifundelwe imiphumela yazo ngesisu esiswini zihlanganisa (β) N-alkanoyl-5-hydroxytryptamides (C5HTs) kanye ne-chlorogenic acids (i-CGAs).
Ucwaningo olulodwa lubonise ukuthi uma okuqukethwe kwe-NMP ekhifini kuphakeme futhi okuqukethwe kwe-C5HT ne-CGA kwakungaphansi, kwakukhona isisu esincane esakhiwe ngabahlanganyeli bokufunda.
Ngakho-ke, kuyilapho i-NMP ingumakhi oyinhloko ekufuneni ikhofi engabangeli izimpawu, ukuba khona kwe-C5HT no-CGA ezindaweni eziphansi nakho kunomphumela. Inhlanganisela engcono kakhulu yokuthola isisu sekhofi enomsoco isisu futhi iyoba enye ephansi e-chlorogenic acids futhi ephakeme ku-NMP.
Ukwengeza ubisi kukhofi kungasiza futhi ukuba ube nesisu esiningi kakhulu, okungenani kulabo abakwazi ukuthola ubisi. Uma ubisi lengezwe ikhofi, amaprotheni amaningana obisi, okufaka i- α -casein, β -casein, κ -casein, α -lactalbumin, ne- β -lactoglobulin, izobopha ama-aclor chlorogenic. Njengoba i-chlorogenic acid iboshelwe iphrotheni, ngeke isenze umsebenzi wayo ukwandisa isisu se-asimende ngoba ayitholakali kalula (okuyisilinganiso sokuthi kalula i-compound ixhunyiwe ngumzimba).
Ukuthola Ukulinganisela Ngakwesokudla Ukukhwabanisa Okumnyama
Ngokuphambene nalokho okungase kubonakale kuyiqiniso, yizinhlobo ezibomvu ezibomvu ezingaba yikhofi elula esiswini. Ucwaningo lubonisa ukuthi ukugcoba okumnyama, kuqhathaniswa nokugcoba okuphakathi, kwandise okuqukethwe kwe-NMP futhi kwehla okuqukethwe kwe-chlorogenic acid.
Kulabo abafuna ikhofi lula kakhulu esiswini, i-roast ebomvu, okungenzeka ibe nezinhlanganisela ezimbalwa ezandisa isisu esiswini kanye namanye amakhemikhali ayanciphisa isisu esiswini, izonikeza ithuba elikhulu kunazo zonke zekhofi engenzi kubangele izimpawu.
Ikhofi elibili elivuthiwe
Abenzi bama-coffees abanjwe kabili bathi inqubo lapho ubhontshisi babo abaphathwa khona kungabangela ikhofi elula esiswini. Lapho abantu abaningi becabanga ngokudla okuvutshiwe bacabanga ngama-probiotics, kodwa ikhofi eqhutshwe ngale ndlela ngeke ikwazi ukufaka noma iyiphi ibhaktheriya ezuzisa uhlelo lokugaya.
Ikhofi ivame ukuvuthwa kanye, kepha abanye abakhiqizi bafaka ukuvutshelwa okwesibili, futhi ngezinye izikhathi kuthiwa "ukufakela kabili" noma "Ukufiswa kwe-Double Kenya" ngoba ikhofi evela eKenya iyaziwa ngale nqubo. Umqondo wukuthi ukuvutshelwa kabili kungasusa " amanothi abuhlungu "futhi wenze ikhofi ibe yinto enhle kakhulu kubantu abanezinkinga zokugaya ukudla.
I-aclor chlorogenic ekhofi okungenani ingxenye ebangela ukunambitheka okubabayo. Ngakho-ke, lo mqondo uwukuthi, okuncane okubabayo ikhofi, ambalwa ama-chlorogenic acids akhona. Kodwa-ke, abukho ubufakazi bokuthi ukuvuthwa okubili kabili kunciphisa inani le-chlorogenic acids, noma ukwandise okuqukethwe kwe-NMP, kokubili okudingekayo ukudala ikhofi eyanciphisa ukukhiqizwa kwe-asidi yesisu.
Ikhofi elihlaza (ama-coffee bezinhlamvu ezingavuthiwe)
Ikhofi eluhlaza yizinhlobonhlobo zebhontshisi yekhofi ezingakaze zithole inqubo yokugaya. Ngaphandle kokugaya ubhontshisi, i-aclor chlorogenic kanye nomthamo we-NMP wekhofi ephuziwe ngeke kuguqulwe, futhi umphumela uwukhofi olungenayo izinzuzo ekunciphiseni ukukhiqizwa kwe-acid esiswini.
Ukwengeza, ikhofi ekhishwe kubhontshisi engavunyelwe ingaba nokunambitheka okubabayo, ngenxa yokuqukethwe okuphezulu kwe-chlorogenic acid.
Ingabe i-Caffeine Content Matter?
Yiziphi abaphuza ikhofi abaningi abakujabulela ngekhofi akuyona imfihlo: kungumuthi we-caffeine. Ibeka ukuvuka nokuhamba ekuseni, futhi kwabanye, ntambama futhi.
Kodwa-ke, ucwaningo oluningi lubonisa ukuthi i-caffeine ayibonakali iyinkinga lapho ecubungula imiphumela yekhofi esiswini. Ucwaningo oluthile olwalubheka izinhlobonhlobo zekhofi ezihlukahlukene kanye nomphumela wazo ekukhiqizeni kwe-asidi yesisu esetshenziselwa ama-coffees afana nokuqukethwe kwe-caffeine ukuze ngisho nenkundla yokudlala. Kucatshangwa ukuthi ama-bioactive compounds athola ikhofi ekhulisa noma eyanciphisa amajusi okugaya esiswini angase ahlanganyele nomunye nomunye kungakhathaliseki ukuthi i-caffeine ingakanani ekhofi.
Imiphumela Yomuntu ngamunye: Uzifaka Kanjani?
Esinye isiqephu se-puzzle yilokho umuntu ngamunye aziphendulela kumakhemikhali kanye nokuqukethwe kwe-caffeine ekhofi. Nakuba izincomo ezibanzi zingenziwa ezifundweni zesayensi, ikakhulu lezo ezifaka izinamba ezinkulu zabantu, kunezinhlobo ezihlukahlukene zemizimba ezingathonya indlela umuntu oyedwa oyithinta ngayo izinhlanganisela zekhofi.
Kunomkhawulo kulokhu kuhluka, ngakho-ke kungase kungabi kubaluleke kakhulu kubantu abaningi, kodwa lokhu kusho ukuthi kungase kube nesilingo nesiphambeko esihilelekile. Ikhofi umuntu afunga ngalo futhi uyakwazi ukuphuza ngaphandle kokushaya isisu kungase kungasebenzi ngendlela efanayo kumuntu wonke. Lokhu kusho ukuthi ukuzama izinhlobo ezahlukene kungaba yingxenye yokuthola ikhofi elula ukugaya.
Imfihlo Yokubheka Ikhofi Engeke Yenze Isimo Sokushaywa Kwesisu
Ngokusekelwe ocwaningweni olutholakalayo, kufushane, nansi okungasiza.
- Hamba ubomvu obumnyama. Kungase kubonakale sengathi ubumnyama ikhofi, izimpawu ezingaphezu kwesisu ezingase zilethe, kodwa okuphambene empeleni kuyiqiniso. Ukupheka ikhofi kuveza okuhle kakhulu kumakhemikhali wemvelo okwenyusa ukukhiqizwa kwesisu esiswini.
- Sebenzisa indlela yokubanda okubandayo. Ukuphuza kwamafutha kuzoholela kukhofi enamazinga aphansi kuwo wonke ama-compounds atholakala kukhofi. Lokhu kusho ukuthi izingxenye zekhofi ezenza ukwanda kwe-asidi esiswini zizobe ziphansi.
- Engeza ubisi. Yiqiniso, lokhu akuyona inketho kulabo abanomsoco kuya kwezimbuzi noma abawugwema ngenxa yokungabekezeki kwe- lactose (esinye isisusa sokukhushulwa kwesisu), kodwa singasiza kulabo abangenayo inkinga yobisi. Ama-proteine omuncu ahlangene namanye amakhemikhali ekhofi avame ukwandisa isisu esiswini.
Izwi elivela
Ngenkathi sekuye kwahlolwa ukuthi kungani izinhlobo ezithile zekhofi zingabangela ukukhiqizwa okungezansi kwe-acids esiswini kunezinye izinhlobo, kusengaphezulu okuningi ukufunda ngale nqubo eyinkimbinkimbi.
Ukuthola ikhofi ephakeme eNMP futhi ephansi kuma-aclor chlorogenic kungase kubangele izimpawu ezimbalwa zesisu ngemuva kokuphuza. Lokhu kungase kwandiswe ngokusebenzisa indlela yokubanda okubandayo nokufaka ubisi. Kodwa-ke, inani elithile lokulinga nephutha lingadingeka ngoba abenzi bekhofi abavakali ngokujwayelekile i-NMP kanye ne-chlorogenic acid okuqukethwe ngobhontshisi babo! Njengoba kunezinhlobo eziningi zama-coffees emakethe, noma kunjalo, kungenzeka ukuthi kube neyodwa ehambisana nokucasula kwesisu esincane.
