Inkukhu ethosiwe: Lena yindlela esebenza ngayo ngokuphelele
Ochwepheshe be-American Chemical Society manje sebefakazele ngokwesayensi ukuthi kungani inkukhu ethoswe ngamafutha ashisayo inambitheka kangaka.
- Ngokusho kongoti, inyama eyosiwe kufanele yoswe emazingeni okushisa aphakathi kuka-150 no-190 degrees Celsius. Isizathu: Kuleli zinga lokushisa, uwoyela ukhiqiza lokho okubizwa ngokuthi ama-triglycerides.
- I-Triglycerides yizici eziyinhloko zamafutha omzimba womuntu. Ngakho inkukhu ethosiwe ayikona ncamashi ukudla okunempilo.
- Ososayensi baphinde bakhombe amagwebu akheka eduze kwenkukhu njengoba iyosa. Incazelo: Uma kushisa, amanzi aphuma ezitokisini zenkukhu futhi lawa akhe amagwebu emafutheni.
- Amagwebu abalulekile ekugazini kahle kwenkukhu. Zakha ungqimba lwesitimu nxazonke zenkukhu, ziyivikele emafutheni futhi zivimbele amafutha ukuthi angangeni enkukhuni ngesikhathi sokuthosa.
- Le nqubo ikhipha amanzi esikhumbeni futhi yenza uqweqwe lube luhle futhi lube crispy.
Inkukhu ethosiwe: Yingakho inuka kancane
Osokhemisi bangachaza nokuthi kungani inkukhu ethosiwe ngezinye izikhathi ingakhipha iphunga eliyinqaba lenhlanzi.
- Iphunga eliyinqaba libangelwa ukufakwa kwe-oxidation lapho inkukhu isabela nomoya-mpilo emoyeni.
- Inkukhu ethoswe ngobumnene inokunambitheka okumnandi, okunebhotela, namantongomane. I-oxidation yamanye ama-fatty acids, njenge-linoleic acid, ikhiqiza izinhlanganisela eziguquguqukayo ezingagcini nje ngokunuka kabi kodwa futhi zihamba kalula emoyeni - ngqo emakhaleni akho.
- Izinhlanganisela ezinjalo eziguquguqukayo ezivela ku-oxidation yama-fatty acids zihlanganisa i-aldehyde ne-carboxylic acid.
- Zombili zinephunga elimnandi. Futhi ngenxa yalokhu kuguquguquka, iphunga elimnandi lenkukhu ethosiwe likhishwa iphunga lezinhlanzi.
- Kodwa ungakwazi ukugwema kalula leli phunga lezinhlanzi. Sebenzisa i-fryer ejulile ngokwanele ukuze ucwilise inkukhu ngokugcwele emafutheni ashisayo.
- Uma inkukhu ilele ngokuphelele emafutheni, umoya-mpilo omncane ungafinyelela enkukhuni futhi i-oxidation ebangela iphunga lezinhlanzi ayenzeki.
- Ngendlela, kufanele futhi uguqule njalo amafutha ku-fryer ukuze ulondoloze yonke i-flavour yenkukhu. Lokhu futhi kususa ama-fatty acids mahhala akha ngesikhathi sokuthosa.
