Rennet - iimpawu kunye nesicelo. Yintoni na le obachaphazela ngayo umzimba womntu

Rennet lulwelo ezintsonkothileyo eziphilayo ethe yaveliswa esiswini lamathole, neemvana kunye nezinye iinkomo kuzalwa. Yinto eyaziwayo ukuba ubuncwane ikhuthaza yokuwa nokurisayikilisha ngobisi lukanina, esebenzisa ithole. Kufuneka kuqatshelwe kanjalo ukuba esi enzayim awukho ngeendlela ngumntu. Kule nkalo, oko luyabiza, kodwa esebenzayo kakhulu ekulungiseleleni iimveliso zobisi.

utsalo ezahlukileyo futhi omisa enzyme

Ukuba ufuna ukupheka itshizi ekhaya okanye cottage itshizi kunye nokusetyenziswa kwemveliso enjalo, oko zingathengwa ekhemesti. Ngokuqhelekileyo zingeniswe nto ethengiswa ngumgubo ekukhanyeni-ngwevu okanye ezimhlophe, nto leyo eye akukho ivumba okanye umbala. Kufuneka kuqatshelwe ukuba amatyathanga kwikhemesti nto wathengisa inqabile kakhulu. Ngoko, xa kungekho mveliso langabom kunokuqulunqwa rennet ekhaya. Ukuze wenze oku, rennet kufunxwa emva ngokubulawa ithole okanye imvana kufuneka zicocwe, kunye iziphelo mingxuma iqhina, yenyuse emoyeni ushiye iintsuku ezimbalwa emthunzini okanye kwigumbi efudumeleyo (18-20 degrees). Okulandelayo, imveliso womisa kufuneka isongelwe ngephepha emnyama sigcine ukuya kusetyenziso ngqo. Kuba nokulungiswa curd samasi okanye kunqweneleka ukuba usebenzise i-enzayimi emva kweenyanga 2-4 emva omiswe, kuba yencindi yinto entsha zingavela isisombululo esetyenzisiweyo.

Yiyiphi rennet kwendima ekuveliseni itshizi kunye nezinye iimveliso zobisi?

Rennet isoloko isetyenziswa ngokwenza netshizi. Eneneni, ebudeni kuveliswe le mveliso kufuna ukwahlukana ngokukhawuleza yeekhomponenti protein i fresh zesiselo ubisi serum. Njengoko usazi, le nto silwanyana iquka izinto ezimbini: pepsin kunye chymosin. Kwaye ngenxa yokuba la macandelo rennet enzyme kuvala ekulungiseleleni sisi okumnandi, nemfesane. Ngapha koko, yokuyifaka ubisi ngokukhawuleza curdled ngokwahlula amacandelo protein of the yintloya.

nokuba babhale sizuze?

Nangona isibakala sokuba eli candelo iyabiza, lisetyenziswa yi kubavelisi yeemveliso zobisi. Emva itshizi ngaphandle rennet wafumana nencasa ngaphantsi maxabiso. Ukongeza, inkqubo olungqumbululu ubisi kunye nokusetyenziswa kweziyobisi kakhulu ngokukhawuleza, nto leyo evumela iimveliso kakhulu ngakumbi.

Kufuneka kuqatshelwe ukuba rennet ayinalo ngenene azinampembelelo iimpawu organoleptic ye imveliso yokugqibela. Ngamanye amazwi, lo sisi wenza kunye nokusetyenziswa kwale nto ayithethi kutshintsha umbala, incasa kunye ihlala nangoku aqholiweyo. Hi ndlela leyi, ngaphandle imveliso yobisi kwakuthetha akunakwenzeka ngokupheleleyo ukuqonda, wenza ukuba usebenzisa enzayimi okanye hayi.

Indlela yokwenza sisi?

Emva kokuba rennet idityaniswe ukuba ubisi, oko iguqulelwa yaba lihlwili ashinyeneyo. Xa oku yintloya siyahlukana kwicandelo protein le. Ukuba kweli nqanaba zokumisa, ngoko ufumana sisi esimnandi kakhulu. Ukuba lufunelwa ukwenza itshizi eqinileyo elimnandi, ingqolowa lifikelele ipesenti ethile ukufuma kufuneka ufakwe kwi imilo amathuba ekufunxeni i-serum, uze emva koko zixinaniswe kwaye wathumela pickling. Le anetyuwa akhiwa imivalo kufuneka ube malunga iintsuku ezili-10, emva koko ke kufuneka ukuba ezishelfini for lokuvuthwa ezipheleleyo (3 iiveki).

Rennet: eziyingozi xa umzimba?

Njengoko kukhankanyiwe ngasentla, kunzima ukumisela, yenziwa ukuba okanye hayi sisi usebenzisa iziyobisi. Ngapha koko, njengenxalenye imveliso loo enzyme an, awusoze kufumana. Oku kungenxa yokuba rennet ayiqukethanga lo sisi okanye cottage itshizi, njengoko isetyenziswa kuphela ubisi olungqumbululu. Nakuba kunjalo, kufanele kuqatshelwe ukuba ukuntsonkotha koko zokususwa wayo ukusuka nezisu amathole abaselula, iimvana, namatakane eebhokhwe, ukususela ekuqaleni kuka-1990, baqalisa ukuvelisa i-enzayim efanayo (rennin) ngenxa biotechnology yemfuza. Umgaqo layo lemveliso malunga ngolu hlobo lulandelayo: ukuba licatshulwa gene isilwanyana iyakotshwa izigidi amaxesha. ke zithe zafakwa kokusingqongileyo iintsholongwane apho bazibonise ngokuzenzela. Okwangoku kuhlala iziphumo ayicacanga kwi iimveliso zilungiselelwe yi ubunjineli yemfuza. Ngokunxulumene nale kancinane nzima kuthi ukuba lo enzyme yingozi okanye hayi.

Yintoni indawo rennet?

Okwangoku, kukho abantu bokubabambela eziliqela rennet, zisetyenziswa ngokubanzi ukwenzela ukulungiselela sisi ezahlukeneyo cottage sisi. ukusebenzisa kwabo kwakhona ethandwa phakathi nabavelisi zobisi. Umzekelo, e-Italy, ukongeza rennet rennet, ukudala zamasi esivumba asetyenziswa, kunye nezinye enzayim ziveliswa iiamangile iimvana, namatakane okanye amathole. izinto ezinjalo banikela imveliso incasa ethile piquant, kakhulu yi gourmets.

Kufuneka kuqatshelwe ukuba ukusetyenziswa kweziyobisi non-isilwanyana xa upheka sisi ikuvumela ukuba usebenzise kubo kunye nabalandeli imifino. Ngoko ke, ngo-1960, abaphandi lineminyaka amagciwane e fungi Mucor miehei kunye Mucor pusilus, ezo kuhlelwe enzayim ezifanelekileyo, kodwa umsebenzi ophantsi. kamva kancinane kuphuhliswa iindlela zokufumana izinto ezifanayo licheniformis inegciwane, mixoides Pseudomonas, Edothea parasitica njalo njalo. Emva kweminyaka engamashumi amathathu, kunye nophuhliso gene biotechnology ekuveliseni zamasi ziye ngenkuthalo kusetyenziswa rennin, leyo yaveliswa iintsholongwane-iikopi abaselula gene ithole. Njengoko yaziwa, ukuba abe ntumbuluko ephakamileyo, uzinzo kunye umsebenzi ngaphezu enjekeni yendalo. Okwangoku, esebenzisa eli candelo yenziwe ngaphezu kwe-60% ye no nzima.

Ukongeza, namhlanje kukho abantu bokubabambela rennet yemifuno. Ngoko ke, endaweni, sebenzisa incindi ngamakhiwane okanye ingca starter. Noko ke, kwimveliso elikhulu-isikali iimveliso zobisi loo enzymes zisetyenziswa kunqabile kakhulu.
