Abun da ke ciki da Halayen Whey
Gabaɗaya, whey ya ƙunshi kusan kashi 93-94% na ruwa da kuma kashi 6-7% na daskararru masu narkewa. Waɗannan daskararru sun ƙunshi lactose (kimanin kashi 70-75% na jimillar daskararru), furotin whey (kimanin kashi 10-15% na daskararru), ma'adanai (toka), da ƙananan abubuwa kamar bitamin masu narkewar ruwa da acid na halitta. Manyan sunadaran da ke cikin whey sune β-lactoglobulin, α-lactalbumin, albumin na serum na bovine, immunoglobulins, da lactoferrin. Halayen whey suna da tasiri ta hanyar nau'in tsarin ƙera: sweet whey yana samuwa ne daga enzyme coagulation (rennet) a cikin yin cuku, yayin da acid whey yana samuwa ne daga acid coagulation (misali, yin yogurt ko sabon cuku). Acid whey yana da ƙarancin pH da kuma ma'adanai daban-daban, don haka dabarun sarrafawa na iya bambanta.
Kalubalen Muhalli da Dalilan Sarrafawa
Whey yana da ƙimar BOD mai yawa (Biochemical Oxygen Buƙatar) da COD (Sinadarin Oxygen Buƙatar) , musamman saboda yawan lactose da ke cikinsa. Idan aka zubar da shi kai tsaye, whey na iya rage iskar oxygen da aka narkar a cikin ruwa da kuma lalata yanayin halittu. Saboda haka, sarrafa whey ba wai kawai ƙoƙari ne na ƙara ƙima ba, har ma da mafita don rage gurɓatawa. Fasaha ta zamani tana neman cire abubuwa masu mahimmanci daga whey da kuma amfani da sauran sassan ta hanyar fermentation ko canza makamashi.
Matakan Asali na Sarrafa Whey
Sarrafa whey gabaɗaya yana farawa da haske da kuma raba kitse . Wannan matakin zai iya amfani da na'urar raba centrifugal don cire ƙananan ƙwayoyin cuta, ragowar curd, da kitse.
