• Umgca wezantsi

Iiproteni zomgubo zizinto ezithandwayo ezithandwayo phakathi kwabantu abazi impilo.

Okwangoku, kuxhomekeke kubude beyiphi ityhubhu yomgubo weprotein kwikhitshi lakho lekhitshi, usenokuzibuza ukuba ingaba ilungile okanye ikhuselekile ukusetyenziswa.

Eli nqaku lixoxa ngokuba iprotein powder iphelelwa lixesha kwaye ikhuselekile ukuba ingadlula ngaphaya komhla wokuphelelwa kwayo.

Iiprotheni ezisisiseko somgubo

Iiprotein powders zinika indlela elula kwaye engabizi kakhulu yokwandisa ukutya kwakho kweprotein.

Nangona ingqwalaselo enkulu ijolise kwimpembelelo yeprotheni yokufumana izihlunu, uphando luyaqhubeka nokutyhila ezinye izibonelelo zokutya okuphezulu kweprotein, kubandakanya ukulahleka kwamafutha, ukuzinza kweswekile yegazi, ulawulo lwexinzelelo lwegazi, kunye nempilo yethambo (,,,).

Iiprotein powders zivela kwimithombo eyahlukeneyo, kubandakanya:

• ubisi - ngohlobo lwewhey okanye ikesi
• isoya
• collagen
• ertyisi
• irayisi
• iqanda elimhlophe

Iimveliso zihlala zinomthombo omnye weprotheni kodwa zinokubonelela ngeprotein evela kwimithombo emininzi ukunciphisa indleko okanye ukutshintsha inqanaba lokufunxa.

Umzekelo, ezinye iipowder powders zinokuqulatha ii-whey ezikhawulezayo ukucola kunye neprotein yokugaya ukutya.

Iiprotein powders zikwabandakanya amanqanaba ahlukeneyo ezinye izakha mzimba, ezinje ngamafutha, iikhabho, iivithamini kunye neeminerali.

Ngapha koko, ngokubanzi ziqulathe izongezo, kubandakanya iincasa zendalo kunye nezokufakelwa, abakhuseli bevumba kunye nezixhasi, kunye neearhente zokuqina ukuze zibonelele ngokuhambelana kwe-creamier kunye ne-mouthfeel.

Iiprotein powders zivela kwimithombo eyahlukeneyo yezilwanyana- kunye nemithombo esekwe kwizityalo. Bahlala benezongezo zokuphucula kunye nokugcina incasa kunye noburhabaxa.

Buyintoni ubomi beshelfoli yeprotein powder?

Ubomi beShelf ngokubanzi bubhekisa ekutyeni okude kugcina umgangatho olungileyo emva kwemveliso.

Abavelisi bokuxhasa akufuneki babandakanye umhla wokuphelelwa kwiimveliso zabo ().

Nangona kunjalo, iinkampani ezininzi ngokuzithandela zibonelela ngokuphelelwa lixesha okanye "okugqwesileyo" ngesitampu kunye nomhla owenziweyo.

Kule meko, kuxhomekeke kumenzi ukuba axhase umhla wokuphelelwa kweemveliso zabo nedatha ukubonisa ukuba ayilahlekisi ().

Uvavanyo olukhawulezileyo lwashelf-life, abaphandi kolunye uphononongo bafumanise ukuba i-whey protein yomgubo inobomi obungaphezulu kweenyanga ezili-12-ukuya kuthi ga kwiinyanga ezili-19 phantsi kweemeko zokugcina eziqhelekileyo, ezichazwa njenge-70 ° F (21 ° C) kunye Ukufuma okungama-35% ().

Uvavanyo olukhawulezileyo lwashelfini yindlela yokulinganisa kunye nokuqikelela uzinzo lwemveliso ngokuyigcina phantsi kweemeko zoxinzelelo, ezinje ngeqondo lobushushu eliphezulu kunye nokufuma.

Kwesinye isifundo, abaphandi baphetha ngelithi iprotein ye-whey inobomi bethuba leenyanga ezili-9 xa igcinwe kuma-95 ° F (35 ° C) kodwa iinyanga ezili-18 ubuncinci xa igcinwe kubushushu begumbi, okanye i-70 ° F (21 ° C) ine-45- Ukufuma okungama-65% ().

Nokuba ubomi beshelfu obucetyiswayo beprotey ye Whey busebenza nakweminye imithombo yeprotini kuhlala kungaziwa, kodwa kusenokwenzeka ukuba kuyafana ukuba zigcinwa phantsi kweemeko ezifanayo.

Kuzo zombini ezi meko, uninzi lweepowder powders kwintengiso ziqulathe izongezo ezonyusa ubomi beshelfifu, njenge-maltodextrin, i-lecithin, kunye netyuwa, evumela ubomi beshelfu malunga neminyaka emi-2 (8,).

Ngokusekwe kuphando olukhoyo, i-whey protein yomgubo inobomi beshelfu yeenyanga ze-9-19 xa zigcinwa phantsi kweemeko eziqhelekileyo. Uninzi lweepowder powders ziqulathe izongezo ezandisa ishelufu ukuya kuthi ga kwiminyaka emibini.

Ngaba iprotein powder ephelelwe yisikhathi inokugulisa?

Ngaphandle kobisi olungumgubo lweentsana, ukuphelelwa okanye ukusetyenziswa kwemihla ayizizo izikhombisi zokhuseleko kodwa ngumgangatho (10).

Iiprotein powders kukutya okuphantsi kokufuma, okuthetha ukuba abathambekele kakhulu ekukhuleni kwebacteria ().

Ngelixa ukutya ipowder powder kungekudala emva kokuphelelwa kwayo kunokwenzeka ukuba kukhuselekile ukuba imveliso igcinwe ngokufanelekileyo, iipowder powders zinokuphulukana nomxholo weprotheni kunye nobudala.

Olunye uphononongo lubonise ukuba i-amino acid lysine ekwiprotheni ye-whey yehle ukusuka kwi-5.5% ukuya kwi-4.2% kwiinyanga ezili-12 xa igcinwe kwi-70 ° F (21 ° C) kunye ne-45-65% yokufuma ().

Nangona kunjalo, iprotein yomgubo esetyenzisiweyo kolu phando ibingaqulathanga nasiphi na isongezo ekuthi iimveliso ezininzi kwintengiso ziqulathe ukwandisa ubomi beshelfufu.

Kuyenzeka ukuba umgubo weprotein uhambe kakubi ngaphambi komhla wokuphelelwa kuluhlu, ngakumbi ukuba awugcinwanga phantsi kweemeko zokugcina ezipholileyo nezomileyo.

Umzekelo, olunye uphononongo lubonise ukuba xa iprotein ye-whey igcinwe kwi-113 ° F (45 ° C) kangangeeveki ezili-15, kwabakho ukwanda okukhulu kwi-oxidation, ekhokelele kwimveliso yeekhompawundi ezahlukeneyo ezibangela utshintsho olungathandekiyo kwincasa (12) .

Ukuxutywa - ukusabela kwamafutha aneoksijini- kunyuka ngexesha lokugcina kunye nokonakalisa umgangatho weeprothini. Amaqondo obushushu aphezulu afanelekile kwi-oxidation, uphando lubonisa ukuba i-oxidation inyuka nge-10-fold kuyo yonke i-50 ° F (10 ° C) ukwanda ().

Iimpawu zokuba umgubo weprotein uhambe kakubi kubandakanya ivumba elibi, incasa ekrakra, utshintsho kumbala, okanye ukugoba ().

Ngokufanayo nokutya ukutya okonakeleyo, ukusebenzisa ipowder powder ngolunye okanye nangaphezulu kwezi mpawu- nokuba ungaphelelwa lixesha - kunokukugulisa.

Ukuba uqaphela nayiphi na imiqondiso yokuba umgubo wakho weprotein uhambe kakubi, kungcono ukuba ulahle ngaphandle.

Iiprotein powder kulindeleke ukuba ikhuseleke ngokukhawuleza emva komhla wokuphelelwa kwayo ukuba akukho zimpawu zibonakalisileyo. Nangona kunjalo, umxholo weprotheni weeprotein powders unokuhla ngokobudala.

Umgca wezantsi

Iiprotein powders zizongezo ezidumileyo ezivela kwimithombo eyahlukeneyo yezilwanyana kunye nezityalo.

Nangona uphando lubonisa ukuba iprotein ye-whey inobomi beshelufu yeenyanga ze-9-19, uninzi lweeprotein zabavelisi bomgubo lubala umhla wokuphelelwa kweminyaka emi-2 emva kwemveliso, enokwenzeka ukuba yenzeke ngenxa yezongezo ezandisa ubomi beshelfini.

Ukutya iiprotein kungekudala emva komhla wokuphelelwa kwayo kunokwenzeka ukuba kukhuselekile ukuba akukho zimpawu zokuba ihambe kakubi, ebandakanya ivumba elibi, incasa ekrakra, utshintsho kumbala, okanye ukugoqana.

Ukuba le miqondiso ikhona, kungcono ukuphosa ibhafu yakho kwaye uthenge entsha.
