Thina ukuphendula imibuzo. Kutheni Apple mnyama phezu cut?

Ihlabathi esiphila iyamangalisa. Ke ukuba abantwana baqonde lula, kunye iminyaka sakuqhela izinto ezininzi kwaye ulibale ngayo ngokukhuselekileyo. Ngenxa yoko, imibuzo umntwana kakhulu elula uyakwazi ukubeka umntu omdala ngxi. Umzekelo: "Kutheni i emnyama apile kwi cut?" Le nkqubo ubhetyebhetye kakhulu, kodwa ayikho elula njengoko kubonakala xa efika kuqala. Ngapha koko, ezahlukeneyo ubumnyama apile ngeendlela ezahlukeneyo, kwaye abanye musa ziyacima.

Obase iintsomi

Amaninzi, xa bebuzwa ukuba kutheni Apple ufumana ubumnyama phezu cut, kwanabo bawevayo kungenxa intsimbi eziqulathwe. Enye ikhosi school of chemistry yaziwa kakuhle ukuba nsimbi a Valence (okanye igcwala karhulumente)-phinde ngo 2 no +3. Ngoko ke, ngo-apile, iba lokuqala elithile igcwala. Noko ke, emva kokuba ukugawula uqalisa ngenkuthalo kungena wadibana emoyeni, leyo oksijini. Ngenxa yoko, i intsimbi oxidized ukuba degrees-3, ke ngoko uze oxide. Kubonakala ukuba iapile i "irusi". Kwaye ke umbala lilelakhe.

Nangona kunjalo, naziphi na yemichiza uyazi ukuba akunjalo. Enye ubunzima yeso malunga 150-160 grams iqulathe milligrams 3.4 kuphela yentsimbi. Ingaba le mali ngokwaneleyo kuwabhuqa inkangeleko lonke iziqhamo? Ngokuqinisekileyo akunjalo. Eneneni, unoxanduva ngomnye umbandela ngokupheleleyo. Emva oku kuyenzeka, kunye namapere, kunye neebhanana. Kodwa awunalo inani elikhulu enjalo yentsimbi.

oonobangela weqiniso

Ngoko kutheni mnyama phezu apile cut, ukuba akukho phantse akukho yentsimbi? Emva umonakalo iziqhamo kwenzeka eziliqela ekudibaneni kwemichiza, ngenxa koko ulahlekelwa kwekhono yayo. Kodwa ukuba uphi na umxokelelwane, ungakwazi ukuqonda unobangela lokwenyaniso.

Njengoko usazi, ama-apile, njengezinye iziqhamo, baba zizityebi Antioxidants. Afana zabizwa iqela polyphenols. Baye amagama ahlukeneyo, kodwa ke mnye - le ephindeneyo phenols ezahlukeneyo (ukuba mazingabhidaniswa yityhefu). Kakade ke, oku kukodwa into aluchaphazeli umbala i-apile, njengoko kunjalo nje enemibala. Kodwa kunjalo iqulathe polyphenol oxidase enzyme, emva koko uqala nawuphi na umonakalo ukusebenzisana bayawafundisisa polyphenols. Yindlela asabela eyinhloko oksijini. Yaye ngenxa yoko, xa apile kumanani amakhulu kwakhiwa quinone, yaye - a oxidizer olomeleleyo. Yiloo nto ke impendulo echanekileyo umbuzo wokuba kutheni Apple ufumana ubumnyama phezu cut.

Indlela ukujongana?

Kakade ke, lo propati-apile ezininzi ongayithandiyo. Iziqhamo ngokukhawuleza alahlekelwe imbonakalo enomtsalane, kwaye fresh zakhutshwa nje imizuzu embalwa uqalisa ukukhangela zange ibenomtsalane kakhulu. Abapheki kudala kunyuka nge ngendlela ukujongana nale yeempazamo. Akwanelanga ukuba itshone miri lemon zixotyulwe afefe yejusi yelamuni. Enye ngobuwena - uvikivwa ukuba isisombululo citric acid imizuzu 1-2 iziqhamo. Ngenxa yoko, i-apile, akuthethi mnyama phezu cut.

Kuba apple juice usungule enye indlela. Ukuze wenze oku, ngobushushu nje imizuzu 20-30 kwi degrees 70-80. Ngenxa yoko, ukuba wonakaliswe polyphenol oxidase. Ngoko ke, akusekho ungakwazi ukuqala inkqubo namachibi xa umgaqo. Apples lonke ngale ndlela, ngelishwa, kungahlali.

Indlela zesayensi

Kucacile ukuba, ngokususa njengenye yeekhomponenti amathathu abasabela, kunokwenzeka ukuqinisekisa ukuba apile hayi engekabuyi. Ngelishwa, akunakwenzeka ukuba balahle polyphenols. Ukongeza, kukholelwa ukuba luncedo eziphilayo. Yaye into yokuqala kwaphunyelelwa - ngaphandle xa i-oksijini. Kuba isale into eyodwa, efana amafutha le apile (ngokomlinganiselo ngamazwe eliphawulwe E901-E913). Noko ke, ngaphambi kokuba ukusetyenziswa iziqhamo ezinjalo zokwaleka ukutya ayinqwenelayo siwabeka.

Kodwa inzululwazi na ukuma. Ngapha koko, oko kudala kwaziwa kutheni Apple ufumana ubumnyama phezu cut. Noqeqesha ngenkqubo iintlobo ezintsha zemfuza-eguqulwe wabonisa ukuba ngokususa i-enzayim ye-oxidant zingafumaneka apile "obungunaphakade" nje. Isisombululo Perfect ukuze noobhazabhaza beevenkile kunye zokutyela. Ingakumbi ukuba uyamthabatha zivale kuphela zofuzo ezithile. Bakholelwa ukuba oku yeyona engenabungozi.
