Thina ukuphendula imibuzo. Kungani Apple mnyama phezu Imi?

Izwe elisizungezile amazing. Futhi uma izingane ziqonde kalula, neminyaka zijwayele izinto eziningi bese uyakhohlwa ngokuphepha. Ngenxa yalokho, imibuzo kakhulu elula ingane Ungabeka omdala kusanesiminyaminya. Ngokwesibonelo: "Kungani i amnyama apula Imi?" Le nqubo ezahlukene kakhulu, kodwa akuyona elula njengoba kubonakala efika kuqala. Phela, ezahlukene mnyama apula ngezindlela ezahlukene, futhi abanye musa mnyama.

Ukuphela the izinganekwane

Ngokuvamile, lapho bebuzwa ukuthi kungani Apple uthola amnyama cut, bezwa ukuthi kungenxa yensimbi equkethwe. Enye Yiqiniso esikoleni yokuthakwa kwamakhemikhali eyaziwayo ukuthi yensimbi has a (noma esimweni namachibi) Valence +2 futhi +3. Ngakho, ngo-apula, it has a kuqala degree of namachibi. Nokho, ngemva ahlabayo iyaqala ngenkuthalo mbeni emoyeni, equkethe-mpilo. Ngenxa yalokho, insimbi oxidized kuya ku-3 degrees, kanjalo zakha oxide. It kuvela ukuthi i aphula "nokugqwala". Futhi umbala olitholayo.

Nokho, noma yimuphi wemithi uyazi ukuthi akusiyo. Omunye apula isisindo mayelana 150-160 amagremu iqukethe 3.4 kuphela angu yensimbi. Ingabe leli nani ngokwanele ukumosha ukubukeka wonke izithelo? Lutho neze. Eqinisweni, it unesibopho kuyindaba ehluke ngophelele. Ngemva lokhu kwenzeka, futhi amagonandoda, nobhanana. Kodwa abanayo zalelo nani elikhulu lensimbi.

izimbangela kweqiniso

Ngakho kungani mnyama phezu apula cut, uma kukhona cishe awekho yensimbi? Ngemva umonakalo izithelo kwenzeka eziningi zamakhemikhali, ngenxa okuyinto elahlekelwa kwekhono yayo. Kodwa uma ukulandelela iketanga, usengakwazi ukuqonda imbangela yangempela.

Njengoba wazi, ama-aphula, njengabanye izithelo, abacebile Antioxidants. Amakhemikhali zabizwa iqembu polyphenol. Sinenkosi amagama ehlukene, kodwa munye - lokhu kwakwakhe kuyinto phenols ezahlukene (akumelwe kudidaniswe kanye nesihlungu). Yiqiniso, lokhu kukodwa kuyisizathu into akuphazamisi umbala i-apula, njengoba nje kungekho nto enemibala emihle. Kodwa namanje iqukethe polyphenol oxidase enzyme, ngemva kwalokho yikuphi ukulimala iqala ngenkuthalo uxhumana polyphenol. The main kulethe ukuphendula mpilo. Futhi ngenxa yalokho, ngo-apula sibaningi kwakhiwa quinone, futhi - a oxidizer eqinile. Lokho impendulo efanele umbuzo wokuthi kungani Apple uthola amnyama cut.

Indlela yokubhekana?

Yiqiniso, lokhu impahla apula amaningi ungathandi. Izithelo ngokushesha ulahlekelwa i ukubukeka ekhangayo, ngisho fresh lisikiwe nje imizuzu embalwa uqala ukubheka hhayi ekhangayo. Sekuyisikhathi eside abapheki beveza indlela yokubhekana nalesi yokusilela. Kuyinto ngokwanele ukuba usike deda lemon ikhasi ufafaze kalamula. Enye samuntu - is sehliselwe imizuzu 1-2 izithelo citric acid isixazululo. Ngenxa yalokho, i-apula akusho mnyama phezu cut.

Ukuze apple juice waqamba enye indlela. Ukuze wenze lokhu, mane nje pasteurized imizuzu 20-30 at 70-80 degrees. Ngenxa yalokho, ukuba wonakaliswe polyphenol oxidase. Ngakho, engasakwazi ukuqala inqubo namachibi ngokomthetho. Ukuze apula wonke ngale ndlela, ngeshwa, kungahlali.

I izindlela ezintsha zesayensi zokufunda

Kusobala ukuthi, ngokususa kwenye yezingxenye ezintathu ukusabela, kungenzeka ukuqinisekisa ukuthi emahhabhula hhayi mnyama. Ngeshwa, akunakwenzeka ukuba balahle polyphenol. Ngaphezu kwalokho, kunenkolelo ukuthi ziwusizo umzimba. Futhi into yokuqala ukuthi yafinyelelwa - ukuwakhipha kusuka ukuphendula oxygen. Ngenxa yalesi apula camera isakhi esithile esikhethekile, efana wax (ngokuvumelana nezindinganiso zamazwe ngamazwe ephawulwe E901-E913). Nokho, ngaphambi kokuba ukusetshenziswa izithelo anjalo ukudla enamathela okunxanelekayo hashaza.

Kodwa isayensi akemi namanje. Phela, sekuyisikhathi eside lwaziwa kungani Apple uthola amnyama cut. Ekwetfuleni izinhlobo ezintsha zofuzo-modified wafakazela ukuthi ngokususa lwe-enzyme-oxidant ingatholakala nje apula "engunaphakade '. ikhambi ephelele nezitolo ezinkulu nezindawo zokudlela. Ikakhulukazi ukuthi uthwebule kuphela ukuvimba izakhi zofuzo ezithile. Kukholakala ukuthi lobu buchwepheshe iyona ayinangozi kakhulu.
