I-Rennet Yasebenzisa Ukwenza Ushizi Kungaba Izilwane, Izitshalo Noma Izibungu
I-Rennet isetshenziswa ngesikhathi senqubo yokuhlola ukugcoba, noma ukunqanda, ubisi zibe ngamakhanda. U-Rennet ngokwejwayelekile uvela ezilwaneni. Ngokuqondile, i-enzyme ebizwa ngokuthi i-chymosin noma i-rennin ethathwe isilonda esiswini sethole, i-ewe noma i-kid (imbuzi yebhongo). Ukusebenzisa isilwane rennet ukwenza ushizi kungaba yinkinga uma ungumvuno.
Nakuba kungavamile, ushizi olunomsoco owenziwe ku-rennet oluvela ezitshalweni noma ezincane ze-rennet iyatholakala.
Plant Rennet
Ngokuvamile, i-rennet esetshenziselwa ukutshala isitshalo ivela ekhadini le-cardoon thistle, ama-artichokes noma ama-nettles. Izitshalo zimanzi emanzini ukuze zithathe i-enzyme eqina efana ne-chymosin. Amaningi amaningi aseSpanishi nesiPutukezi asenziwa ezitshalweni ze-rennet.
I-rennet yezitshalo ingaveza imiphumela engavumelani phakathi nenqubo yokuhlakulela uma umkhiqizo ongeke uqaphele. I-rennet yezitshalo nayo ingathinta ukunambitheka kwe-ushizi, okungaba into enhle noma embi, kuye ngokuhloswe kwe-cheesemaker.
I-Microbial Rennet
Ezinye izibunji zine-enzyme efana ne-chymosin. La ma-enzyme akhishwa ebhodini yokwenza i-rennet ye-microbial. I-rennet ye-Microbial ayisetshenziswanga kakhulu ngoba ayinikezi imiphumela eqhubekayo. Kuyinkimbinkimbi ukusebenzisa ngesikhathi senqubo yokuhlola, futhi ushizi olwenziwe nge-micronetal rennet lungakha ama-flavour angathandeki.
I-rennet ye-microbial ingahle ishintshwe ngokofuzo. Ukwenza i-rennet enezakhi zofuzo, ama-chromosomes e-chymosin akhishwa esitokisini sezilwane zesilwane bese efakwa zibe yizinkwa zesilonda ezisebenza njengezivakashi.
Isiko lesivakashi sikhuthaza ukukhula kwama-enzyme amasha e-chymosin. Ama-enzyme amasha e-chymosine ahlukaniswa futhi ahlanzwe.
Nakuba i-rennet yezofuzo ezakhiwe ngokofuzo ivela esitokisini sesilwane, kubhekwa abanye ukuba babe nobungani bemifino. I-rennet ene-genetically engu-gene iyisizukulwane esisha se-enzyme esizalwe esitokisini sezilwane, kodwa hhayi empeleni umkhiqizo wesilwane ngokwawo.
Ngingazi kanjani ukuthi ushizi luyenziwa nge-Rennet yemifino?
I-FDA ayidingi abahloli bezinhla ukucacisa uhlobo luni lwe-rennet abayisebenzisayo. Kodwa-ke, i-rennet eyenziwa nge-chymosin yezilwane ivame ukubizwa ngokuthi "i-rennet yendabuko" elebula le-cheese, kuyilapho abaningi abakhiqizi abasebenzisa i-rennet yezitshalo basho "u-renist plant" noma "isitshalo se-rennet" noma "i-rennet yemifino" kulelebula.
Ukubheja kwakho okuphephile kakhulu ukuthenga ushizi esitolo se-cheese nama-cheesemongers abanolwazi. Kufanele bakwazi ukukhomba wonke ushizi esitolo esingeke senziwe kusuka ku-rennet yezilwane. Ukuze uthole isiqondiso esengeziwe, thinta lolu hlu oluyingxenye yezitshalo zobunikazi ezenziwe nge-rennet yemifino.
