Whey protein
I-Whey protein iyinhloko yeprothini ecelwa ngokwenziwa kwawo ngesichitho esikhanyayo sokwenza isibindi somhlaba, etholakala njengombiko wemali engakaze kube ngowokwenza ubisi. I-prothini zikhona i-α-lactalbumin, β-lactoglobulin, i-serum albumin kanye ne-immunoglobulins.[1] I-Glycomacropeptide ikhona futhi isisebenziswe njengomkhiqizo wezigaba zesine, kodwa akuyona yeprothini. I-Whey protein kumele iqinisekise njengemkhiqizo wemfuzo yeprothini, futhi khona imiyalo yemindeni emikhulu ephambili kwaso. Uhlu lwezincwadi olukhombisa 2010 kwi-European Food Safety Authority Journal lwavumela ukuthi inkulumo edingekayo ayinikwa ikholwa lombiko.[2] Ngokokuthi ingozi yemisipha, I-Whey protein ibonisa ukuthi iyatholakala kangcono kumathiphu aphikisayo wemfuzo yeprothini, njengoba ikhona I-casein noma isoy.[3][4]
Ukwenziwa kwe-whey[hlela | Hlela umthombo]
Template:Main article Ukwenziwa kwe-whey kubuya uma umlilo usele waphakathi uma kuqashulwe ubisi ngenkathi ukwenza ubelele, kanye nezinto zonke ezibonakalayo ezizikhanyisiwe kwibisi ngemuva kokubayisha i-pH kuya ku-4.6 ngenkathi kwenziwa ubelele. Kungukwengeza yezinye i-5% yelactose ngamanzi kanye nezithakazelo zokunyakaza zibisi kanye nezinsimbi zokunyakaza.[5] Inkampani yangaphambili kuyenza ngokuthula ukucikidwa, noma isici seprothini sokuqinisekisa kubalwa yilactose, izinsimbi kanye nezinto ezikhiqizwe ezikungapheliyo ezizinsimbi.[6] Isikhombisa, ukulungiswa kwezimembwembe kuyotholakala izinsimbi ngezinsimbi, i-lactose kanye nezizwe ezifileyo ezindawo ezindawo ezizodwa ezisondelayo.[7]
Ukucikidwa kwe-whey kungashintsha ngokukhishwa. Ukucikidwa okukhulu (njengoba kwenziwe ezindaweni ezenzakalelayo ezenzakalelayo ngaphansi kwezinsimbi ezincane ngenxa yokuphakama kwe-72 °C ezinethiwele ngokufezekisa) kucikisa izinsimbi zewhey. Ngesikhathi ukuphakama kwe-whey protein yangaphambili akukhombisi ukuncikiswa uma kwenziwa umsele kanye nokuthunyelwa kombilisela noma uthutha i-bisi, ukucikiswa kweprothini kwe-whey kugxila izinhlamvu ze-protein ezine, futhi kushintsha umbilisela we-protein.[6]
