Rennet - izakhiwo kanye isicelo. Uyini umthelela it has emzimbeni womuntu

Rennet kuyinto into eziyinkimbinkimbi organic olukhiqizwa esiswini lamathole, amawundlu nezinye izinkomo ezisanda kuzalwa. Kuyaziwa ukuthi ketshezi ikhuthaza ukuwohloka futhi kabusha ubisi lukamama, esebenzisa ithole. Kumele kuqashelwe ukuthi le enzayimu ngeke kutholakale ngemishini. Kule ndaba, kuba impela eqolo, kodwa ngempumelelo kakhulu ekulungiseleleni imikhiqizo yobisi.

isizinda Hlukanisa nokwesula enzyme

Uma ufuna ukupheka ekhaya ushizi noma cottage shizi nokusetshenziswa umkhiqizo esinjalo, angathengwa at ekhemisi. Ngokuvamile okufakiwe isithako edayiswa powder ukukhanya-grey noma elimhlophe, esingeyena iphunga noma umbala. Kufanele kuphawulwe ukuthi ekhemisi ngamaketanga ke ithengiswe ezingavamile kakhulu. Ngakho, ngenxa yokuntuleka kwezinhlelo ezibanzi umkhiqizo ekhiqizwa ingalungiswa rennet ekhaya. Ukuze wenze lokhu, rennet ekhishwe ngemva ekubulaleni ithole noma imvu kufanele ahlanze, nemikhawulo yomhlaba imigodi uthayi kufuthwe emoyeni futhi ushiye izinsuku ezimbalwa emthunzini noma endlini efudumele (18-20 degrees). Ngokulandelayo, umkhiqizo omisiwe kufanele zihambisana ephepheni omnyama futhi sigcine ukusetshenziswa ngqo. Ukuze ukulungiswa curd ushizi noma efiselekayo ukusebenzisa i-enzyme ezinjalo ngemva kwezinyanga 2-4 emva omiswe, ngoba fresh isithako isikhwehlela zingavela ikhambi esetshenziswa.

Yini rennet indima udlala ukukhiqizwa ushizi kanye neminye imikhiqizo yobisi?

Rennet ngokuvamile esetshenziselwa ukwenza ushizi. Ngempela, ngesikhathi ukukhiqizwa lo mkhiqizo kudinga ukwahlukaniswa okusheshayo yezingxenye amaprotheni fresh ubisi isiphuzo kusukela serum. Njengoba wazi, yalolu ketshezi isilwane inezigaba ezimbili: pepsin futhi chymosin. Futhi ngenxa yokuthi lezi enzyme izingxenye rennet uba kulethe ekulungiseleleni ushizi esihlwabusayo ithenda. Phela, ukulifaka ubisi curdled ngokushesha esasihlukanisa izingxenye amaprotheni we whey.

ukuthi abakhiqizi sizuze?

Naphezu kweqiniso lokuthi le ngxenye kuyabiza, futhi kunenkolelo eyaziwayo esetshenziswa abakhiqizi imikhiqizo yobisi. Ngemva ushizi ngaphandle rennet etholwe ngaphansi esihlwabusayo ithenda. Ngaphezu kwalokho, inqubo nobisi oluvuthwayo nokusetshenziswa ketshezi ishesha kakhulu, okuvumela imikhiqizo okuningi.

Kufanele kuqashelwe ukuthi le rennet ayinalo nhlobo ithonya phezu izakhiwo organoleptic yomkhiqizo wokugcina. Ngamanye amazwi, lo ushizi enziwe ukusetshenziswa yalolu ketshezi asishintshi umbala, ukunambitheka kanye uhlala namanje elimnandi. By endleleni, ngaphandle umkhiqizo yobisi kwakusho ngokuphelele ayiqondakali, senziwa usebenzisa i-enzyme noma cha.

Indlela yokwenza ushizi?

Ngemva rennet yengezwe ubisi, it is iguqulwe ibe ihlule obukhulu. Uma lokhu whey ahlukaniswa ingxenye amaprotheni. Uma ngalesi sigaba sime ukukhiqiza ke uthola ushizi ezihlwabusayo kakhulu. Uma-ke kuyadingeka ukuba enze ushizi okuqinile futhi flavorful, okusanhlamvu ifinyelele kumaphesenti athile nomswakama kumele ayifake Umumo amathuba nkinga lo serum, bese onomfutho futhi ithunyelwa pickling. I brine ezakhiwe Amabha kufanele kube izinsuku mayelana 10, ngemva kwalokho kwakudingeka ukubeka emashalofini for yokuvuthwa full (3 amaviki).

Rennet: Iyingozi uma umzimba?

Njengoba kushiwo ngenhla, kunzima ukunquma, senziwa ukuthi noma hhayi ushizi usebenzisa izidakamizwa. Phela, njengoba ingxenye umkhiqizo enzyme ezinjalo, ngeke umthole. Lokhu kungenxa yokuthi rennet akuyona eziqukethwe ushizi noma cottage shizi, njengoba isetshenziselwa kuphela ubisi curdling. Nokho, kufanele kuphawulwe ukuthi eyinkimbinkimbi kusho kususwe izisu amankonyane, kwamawundlu namazinyane, kusukela ekuqaleni kwawo-1990, waqala ukuveza enzyme efanayo (rennin) ngenxa ye-biotechnology zofuzo. yokukhiqiza wayo isimiso cishe kanje: ke akhishwa isakhi sofuzo isilwane okuyinto ukopishiwe izigidi izikhathi. Basuke-ke wabeka ku imvelo webhaktheriya which they etshalwa eyayenziwe. Okwamanje uhlala imiphumela alizichazi imikhiqizo okuye okulungiselelwe genetic engineering. Ngokuqondene nalokhu kancane kanzima ukusho ukuthi lokhu enzyme kuyalimaza noma cha.

Yini esikhundleni rennet?

Okwamanje, kunezinhlobo esikhundleni eziningana for rennet, asetshenziswa kabanzi ukulungiswa ushizi ehlukahlukene cottage shizi. Ukusebenzisa kwabo futhi ethandwa phakathi abakhiqizi yobisi. Ngokwesibonelo, e-Italy, ngaphezu rennet rennet, ukudala zisetshenziswa a ushizi elimnandi, nezinye enzyme ukuthi kukhiqizwa alimondi amawundlu, izingane noma amathole. izinto ezinjengalezi zinikela umkhiqizo ukunambitheka ethize piquant, kuyancomeka ngu gourmets.

Kufanele kuphawulwe ukuthi ukusetshenziswa non-isilwane izinto ngesikhathi ukupheka ushizi ikuvumela ukuzisebenzisa futhi abalandeli imifino. Ngakho, ngo-1960, abacwaningi baye isehlane zakulezi isikhunta Mucor miehei futhi Mucor pusilus, okuyinto kuhlelwe enzyme ofanele, kodwa umsebenzi ongaphakeme. Kancane kamuva nezindlela yokuthola izinto ezifanayo kusukela Bacillus licheniformis, Pseudomonas mixoides, Edothea parasitica nokunye. Ngemva kwamashumi eminyaka emithathu, ukuthuthukiswa isakhi sofuzo i-biotechnology ukuze kukhiqizwe ushizi ziye ngenkuthalo esetshenziswa rennin, okuyinto kwatholwa amabhaktheriya-amakhophi abasha ithole zofuzo. Njengoba yaziwa, it has a eliphakeme ubumsulwa, ukuzinza kanye umsebenzi kuka abomasum zemvelo. Okwamanje, usebenzisa le ngxenye wenziwe ezingaphezu kuka-60% no kanzima.

Ngaphezu kwalokho, namuhla kukhona yemifino rennet esikhundleni. Ngakho, esikhundleni, sebenzisa umpe amakhiwane noma utshani ukuziqalela. Nokho, ekukhiqizeni emikhulu imikhiqizo yobisi enzyme ezinjalo zisetshenziswa kakhulu kuyaqabukela.
