Kungani i-nitrogen isetshenziswa ekukhiqizweni kwe-margarine?

Lapho kukhiqizwa i-margarine, ukwethulwa kwe-nitrogen (noma amanye amagesi angasebenzi njenge-hydrogen) kusekelwe kakhulu kulezi zizathu ezilandelayo ezibalulekile:

1. Ukwandisa isikhathi sokuphila kweshelufu (i-antioxidation)

• Ukuvimbela ukuminyana kwamafutha: Uwoyela wemifino noma amafutha ezilwane kukhilimu wokwenziwa aqukethe ama-fatty acid angagcwele, avame ukuminyana lapho evezwa umoya-mpilo, okuholela ekugugeni (okukhiqiza iphunga elibi). Ukungenisa igesi ye-nitrogen kungasusa umoya-mpilo osephaketheni, kudale indawo engenawo umoya-mpilo, kubambezele kakhulu inqubo yokuminyana.

• Ukunciphisa ukuthembela kuma-antioxidant okwenziwa (njenge-BHA, i-BHT): Lokhu kunciphisa isidingo sama-preservatives amakhemikhali futhi kuhlangabezana nesidingo sabathengi "selebula elihlanzekile".

2. Ukuthuthukisa ukuthungwa nokunambitheka

• Ukwanda kokuthamba: Ngokufaka ngokushesha igesi ye-nitrogen emafutheni, kwakheka amabhamuza amancane, okwenza ukhilimu wokwenziwa ube lula futhi ube mnene kakhulu ekuthungeni, usondela ekuthungeni okuthambile kokhilimu wemvelo.

• Ukulawula ukuqina: Isakhiwo se-foam ye-nitrogen sisiza ekuqiniseni isimo somkhiqizo, okwenza kube lula ukuwusebenzisa (ikakhulukazi ukhilimu wokwenziwa othambile).

3. Ukuvimbela ukukhula kwamagciwane

• Ukuvinjelwa kwamagciwane asebenzisa umoya-mpilo: Amabhaktheriya amaningi kanye nezikhunta zidinga umoya-mpilo ukuze zande, futhi indawo engenawo umoya-mpilo inganciphisa ingozi yokungcoliswa kwamagciwane futhi yandise isikhathi sokuphila komkhiqizo.

4. Izinzuzo zenqubo kanye nezindleko

• Ukufaka igwebu ngokomzimba: Uma kuqhathaniswa nezinto ezifaka imvubelo ngamakhemikhali, ukugcwalisa i-nitrogen kuyindlela ebonakalayo engadingi izithasiselo ezengeziwe futhi inezindleko eziphansi ngenkathi ingathinti ukunambitheka.

• Ukuvikelwa kokupakishwa: Ukugcwaliswa kwe-nitrogen ngaphambi kokupakishwa kungavimbela umkhiqizo ukuthi ungaguquki ngenxa yengcindezi ngesikhathi sokuthuthwa.

Incazelo eyengeziwe:

• Ukuphepha kwe-nitrogen: I-nitrogen (N₂) iyigesi engasebenzi, ayinambala futhi ayinaphunga, ebanga u-78% wokwakheka komoya. Ayinangozi emzimbeni womuntu futhi ayihambisani nezithako zokhilimu wokwenziwa.

• Ezinye izinhlelo zokusebenza: Amasu afanayo asetshenziswa nasekupakisheni ukudla okufana nama-potato chips nekhofi ukuze kulondolozwe.

Ngokugcwalisa nge-nitrogen, i-margarine ingaba nokuthungwa okungcono, ukubukeka, kanye nesikhathi sokuphelelwa yisikhathi esingcono kunokhilimu wemvelo, kuyilapho ihlangabezana nezidingo zokukhiqiza kwezimboni.
