• Amaprotheni ayisisekelo se-powder
• Iyini impilo yeshalofu le-protein powder?
• Ngabe iprotheni powder ephelelwe yisikhathi ingakugulisa?
• Okubalulekile

Amaphrotheni izimpushana ziyisengezo esidume ngokumangazayo phakathi kwabantu abazi impilo.

Noma kunjalo, kuye ngokuthi isikhathi eside kangakanani lelo bhavu le-protein powder lisekhabhineni lakho lasekhishini, ungazibuza ukuthi ingabe kusalungile yini noma kuphephile ukusetshenziswa.

Lo mbhalo uxoxa ngokuthi ngabe iprotheni powder iphelelwa yisikhathi yini nokuthi ngabe kuphephile yini ukusebenzisa ngaphezu kosuku lokuphelelwa yisikhathi.

Amaprotheni ayisisekelo se-powder

Amaphrotheni izimpushana zinikeza indlela elula futhi engabizi kakhulu yokwandisa ukudla kwakho kwamaprotheni.

Yize ukunakwa okuningi kugxile emiphumeleni ezuzisayo yamaprotheni ekuzuzeni kwemisipha, ucwaningo luyaqhubeka nokuveza ezinye izinzuzo zokufakwa kwamaprotheni aphezulu, kufaka phakathi ukulahleka kwamafutha, ukuzinza koshukela wegazi, ukulawula umfutho wegazi, kanye nempilo yethambo (,,,).

Amaphrotheni izimpushana zivela emithonjeni ehlukahlukene, kufaka phakathi:

• ubisi - ngesimo se-whey noma i-casein
• isoya
• collagen
• ipea
• irayisi
• iqanda elimhlophe

Imikhiqizo ngokujwayelekile iqukethe umthombo owodwa wamaprotheni kepha ingaphinde inikeze amaprotheni emithonjeni eminingi ukunciphisa izindleko noma ukuguqula isilinganiso sokumunca.

Isibonelo, amanye ama-powders wamaprotheni angaqukatha womabili amaprotheni we-Whein-digesting fast and slow-digesting casein.

Amaphrotheni powders afaka namazinga ahlukahlukene ezinye izakhamzimba, njengamafutha, ama-carbs, amavithamini, namaminerali.

Futhi, ngokuvamile aqukethe izithasiselo, kufaka phakathi ukunambitheka kwemvelo nokwenziwe, izivikeli zokunambitheka nezithuthukisi, kanye nama-thickening agents ukunikezela ukuvumelana kwe-creamier ne-mouthfeel.

Amaphrotheni izimpushana zivela emithonjeni ehlukahlukene yezilwane nezitshalo. Imvamisa ziqukethe izithasiselo zokuthuthukisa nokulondoloza ukunambitheka nokuthungwa kwazo.

Iyini impilo yeshalofu le-protein powder?

Impilo eshalofini imvamisa ibhekisa ekutheni ukudla kugcina isikhathi esingakanani ngemuva kokukhiqizwa.

Abakhiqizi bokwengeza akudingeki ukuthi bafake usuku lokuphelelwa yisikhathi emikhiqizweni yabo ().

Kodwa-ke, izinkampani eziningi zinikela ngokuzithandela ngokuphelelwa yisikhathi noma ngesitembu "esihle kakhulu" kanye nosuku olwenziwe.

Kulezi zimo, kuya kumkhiqizi ukuthi asekele usuku lokuphelelwa yisikhathi kwemikhiqizo yabo nedatha ukukhombisa ukuthi ayidukisi ().

Besebenzisa isivivinyo sempilo eshisiwe esisheshayo, abacwaningi ocwaningweni oluthile bathole ukuthi i-whey protein powder inempilo eshalofini engaphezulu kwezinyanga eziyi-12 - kuze kufike ezinyangeni eziyi-19 ngaphansi kwezimo zokugcina ezijwayelekile, ezichazwa njenge-70 ° F (21 ° C) kanye Umswakama ongu-35% ().

Isivivinyo sempilo eshisiwe esheshayo kuyindlela yokulinganisa nokulinganisa ukuzinza komkhiqizo ngokuwugcina ngaphansi kwezimo ezicindezelayo, njengokushisa okuphezulu nomswakama.

Kwesinye isifundo, abacwaningi baphetha ngokuthi iprotheni ye-whey inempilo eshalofini yezinyanga eziyi-9 lapho igcinwe ku-95 ° F (35 ° C) kepha okungenani izinyanga eziyi-18 lapho igcinwe ekamelweni lokushisa, noma i-70 ° F (21 ° C) eno-45- Umswakama ongu-65% ().

Ukuthi ishelufu eliphakanyisiwe le-whey protein lisebenza yini kweminye imithombo yamaprotheni kuhlala kungaziwa, kepha kungenzeka kufane uma kugcinwa ngaphansi kwezimo ezifanayo.

Kunoma ikuphi, izimpushana eziningi emakethe ziqukethe izithasiselo ezandisa impilo yeshalofu, njenge-maltodextrin, i-lecithin, nosawoti, okuvumela impilo yeshalofu cishe iminyaka emibili (8,).

Ngokuya ngocwaningo olutholakalayo, i-whey protein powder inempilo yeshalofu yezinyanga eziyi-9-19 lapho igcinwa ngaphansi kwezimo ezijwayelekile. Iningi lama-powders we-protein aqukethe izithasiselo ezinweba impilo yeshalofu kuze kube yiminyaka emi-2.

Ngabe iprotheni powder ephelelwe yisikhathi ingakugulisa?

Ngaphandle kwefomula yosana, ukuphelelwa isikhathi noma ukusetshenziswa kwezinsuku akuyona inkomba yokuphepha kepha ikhwalithi (10).

Amaphrotheni izimpushana ukudla okuphansi komswakama, okusho ukuthi azijwayele ukukhula kwegciwane ().

Ngenkathi kudla iprotheni powder kungekudala ngemuva kosuku lokuphelelwa yisikhathi kungenzeka kuphephile uma umkhiqizo ugcinwe kahle, amaprotheni powders angalahlekelwa okuqukethwe kwamaprotheni ngobudala.

Ucwaningo oluthile lukhombisile ukuthi i-amino acid lysine ephrotheni ye-whey yehle isuka ku-5.5% yaya ku-4.2% ezinyangeni eziyi-12 lapho igcinwe ku-70 ° F (21 ° C) nomswakama ongu-45-65% ().

Kodwa-ke, i-protein powder esetshenziswe kulolu cwaningo ibingenazo izithasiselo ezinemikhiqizo eminingi emakethe equkethe ukwelula impilo yazo eshalofini.

Kungenzeka futhi ukuthi i-protein powder ihambe kabi ngaphambi kosuku lokuphela kwesikhathi esisohlwini, ikakhulukazi uma ingagcinwanga ngaphansi kwezimo zokugcina ezipholile nezomile.

Isibonelo, ucwaningo oluthile lukhombisile ukuthi lapho amaprotheni e-whey egcinwa ku-113 ° F (45 ° C) amasonto ayi-15, kube nokwanda okukhulu kwe-oxidation, okwaholela ekukhiqizweni kwamakhemikhali ahlukahlukene abangela ushintsho olungathandeki kunambitha (12) .

I-oxidation - ukusabela kwamafutha anomoya-mpilo - kuyanda ngesikhathi sokugcina futhi kulimaza ikhwalithi yamaprotheni izimpushana. Amazinga okushisa aphezulu alungele uketshezi lwe-oxidation, ucwaningo luphakamisa ukuthi i-oxidation inyuka ngo-10-fold kuyo yonke i-50 ° F (10 ° C) ukwanda ().

Izimpawu zokuthi i-protein powder ihambe kabi ifaka iphunga elibi, ukunambitheka okumunyu, ushintsho kumbala, noma ukuhlangana ().

Ngokufanayo nokudla ukudla okonakele, ukusebenzisa i-protein powder ngoyedwa noma ngaphezulu yalezi zimpawu - kungakhathalekile usuku lokuphelelwa yisikhathi - kungakugulisa.

Uma ubona noma yiziphi izimpawu zokuthi i-protein powder yakho ihambe kabi, kungcono ukuyilahla.

Amaphrotheni powder kungenzeka aphephile ukuthi awadle ngemuva nje kokuphela kokuphela kwawo kwesikhathi uma kungekho zimpawu zokuthi konakele. Kodwa-ke, okuqukethwe kwamaprotheni ama-powders we-protein kungancipha ngobudala.

Okubalulekile

Amaphrotheni izimpushana yizithasiselo ezidumile ezivela emithonjeni ehlukahlukene yezilwane nezitshalo.

Yize ucwaningo luphakamisa ukuthi i-whey protein inempilo yeshalofu yezinyanga eziyi-9-19, abakhiqizi abaningi be-protein powder babhala usuku lokuphelelwa yisikhathi seminyaka emi-2 ngemuva kokukhiqizwa, okungenzeka ukuthi kwenzeke ngenxa yezithasiselo ezandisa impilo yeshalofu.

Ukudla amaprotheni ngemuva nje kosuku lokuphelelwa yisikhathi kungenzeka kuphephe uma kungekho zimpawu zokuthi konakele, okubandakanya iphunga elibi, ukunambitheka okumunyu, ushintsho kumbala, noma ukuhlangana.

Uma ngabe lezi zimpawu zikhona, kungcono ukuphonsa ubhavu wakho bese uthenga okusha.
