Ukuhlanganisa Ubisi Ngenkathi Yokugaya Insimbi
Ukwenza ushizi kuhilela izinyathelo eziningi, kodwa empeleni kuyindlela nje yokuguqula uketshezi oluqinile. URennet udlala indima ebalulekile ekwenzeni lokhu kwenzeke.
I-Rennet isetshenziselwa ukugcoba, noma ukwehlisa ubisi ngesikhathi senqubo yokuhlola. I-chymosin (ebizwa ngokuthi i-rennin) yi-enzyme esetshenziselwa ukukhiqiza i-rennet.
Ngemuva kokuba ubisi luqoqwe, inqubo yokwenza isilwane iqala ngokungeza amasiko okuqala aguqula i-lactose (ushukela wobisi) abe yi-lactic acid.
Le nqubo ishintsha izinga le-acidity yobisi futhi iqala inqubo yokwandisa ubisi ngokuqinile. Okulandelayo, i-rennet yengezwa ukukhuthaza ukuqina okukhulu nakakhulu ukuze amafolda afomu futhi ahlukaniswe no-whey (uketshezi).

I-Rennet itholakala komunye wemithombo emine ngezansi. Kodwa-ke, i-US Food and Drug Administration (FDA) ayidingi abahloli bezinhla zokucacisa uhlobo luni lwe-rennet abayisebenzisayo.
I-Stomach Lining of Calf, Ewe noma Kid (Baby Goat)
I-chymosin ye-enzyme itholakala ekugumbeni kwesisu kwezilwane ngoba kuyasiza ekugayeni ubisi lwawo. I-Rennet eyenziwe nge-chymosin yezilwane ivame ukubizwa ngokuthi "i-rennet yendabuko" kumalebula ashizi , kodwa, njengoba kuboniswe ngenhla abakhiqizi abadingeki ukuthi bachaze uhlobo luni lwe-rennet abayisebenzisayo.
Izilwane azibulawa ngakho abacuki bangakwazi ukukhiqiza i-rennet. Kunalokho, lezi zilwane zithengiselwa inyama futhi njengendlela yokusebenzisa sonke isilwane, izakhi ze-enzyme zesisu nazo zikhishwe ekukhiqizeni i-rennet.
I-rennet yezilwane ayithinti ngokuqondile i-flavour of ushizi.
Plant Rennet
I-rennet esekelwe ezitshalweni itholakala ku-cardoon thistle, i-artichoke, izinhlanzi nezinye izitshalo. Izitshalo zimanzi emanzini ukuze zithathe i-enzyme eqina efana ne-chymosin. I-rennet ye-Plant-based ingaba inselele ukusebenza nabo ngezizathu ezimbili.
Enye, amandla esitshalo se-rennet akahlali njalo. Ukwazi ukuthi kungakanani okumele ukengeze ngesikhathi senqubo yokuhlakulela ukugcoba ubisi kungaba nzima.
Ezimbili, izitshalo ze-rennet zithinta ukunambitheka kwesizi. Lokhu kungaba yinto enhle. Izinhlobo eziningi zama-ushi ezivela ePortugal zenziwa ngokusebenzisa i-renist rennet, okunikeza ushizi i-flavour ehlukile neyingqayizivele. Ezinye izibonelo yiTorta del Casar, Azeitao , uSerra da Estrela noSerena. Kodwa-ke, i-rennet ye-thistle nayo ingenza futhi ushizi ube yimifino emnandi noma ebabayo , okuyisizathu esithile abanye abahlaziyi bezigwema.
Abakhiqizi abaningi abasebenzisa i-rennet esetshenziselwa izitshalo bazocacisa lokhu kwilebula, nakuba kungadingeki. Uma kungekho elebula, i-cheesemonger ekwaziwa ngokuvamile izokwazi uma ushizi lwenziwe nge-rennet yemifino. Buza esitolo sakho se-ushizi noma uhlole lolu hlu oluthile lwezinyosi ezenziwe nge-rennet yemifino.
I-Genetically-Engineered Rennet noma i-Fermentation-Yenziwe i-Rennet
Ukwenyuka komhlaba jikelele kwemfuno yezinkomo zendabuko i-rennet kwaholela ekwenzeni olunye uhlobo lwe-rennet, olusebenza kanye ne-rennet yezilwane kepha lungenziwa ebhokisatri.
Ama-chromosomes e-chymosin akhishwa esitokisini sezilwane zesilwane bese efakwe emasimini amasiko asebenza njengesibamba.
Isiko lesivakashi sikhuthaza ukukhula kwama-enzyme amasha e-chymosin. Ama-enzyme amasha e-chymosine ahlukaniswa futhi ahlanzwe.
Nakuba ukukhiqizwa ngokwezakhi / izitshalo ezenziwe ngokwezakhi zofuzo ezikhiqizwa i-rennet zivela esitokisini sesilwane, kubhekwa njengento yaso, isizukulwane esisha se-enzyme uma uthanda. Ngakho-ke, kubhekwa njengobungani bemifino. Kodwa-ke, izimvini nezitshalo kumele zizinqumele uma zizodla lolu hlobo lwe-rennet. Ukugwema kungenzeka kungabi lula; lolu hlobo lwe-rennet ebiza izindleko futhi oluthembekile lisetshenziselwa kakhulu ekuhloliseni.
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 ingenza inqubo yokugaya izinhlanzi ibe nzima futhi unike ushizi ukunambitheka okubabayo.
I-rennet yezilwane zendabuko kanye ne-rennet yezakhi zofuzo ngokuvamile iveza imiphumela ehambisanayo; i-rennet ye-microbial ayikho.
Hhayi nje izinyosi ezinzima ezine-rennet kuzo. Iningi lamanzi athambile kanye noshizi olusha lwenziwa ngokusebenzisa i-rennet kanye. Kukhona okunye okwehlukile, noma kunjalo, njenge-ricotta ne-quark, okuvame ukungenayo i-rennet. Ungenza futhi izinhlobo eziningana ushizi ekhaya uhlanganiswe ne-asidi esikhundleni se-rennet:
- Ushizi we-Yogurt ozenziwe
