Izinti Zengulube Ebilisiwe Eqandisiwe
Isingeniso somkhiqizo | Izinto zokusetshenziswa zivela ezilaheni kanye namabhizinisi abhalisela ukuthekelisa eChina.Izinto zokusetshenziswa ezingenisiwe zivela ikakhulukazi eFrance, eSpain, eNetherlands, njll. |
ukucaciswa | Ukucaciswa okwengeziwe, yamukela inkambiso |
izici | Isilinganiso samafutha kuya mncane ngu-3:7, amafutha kodwa anganamafutha. |
Faka isiteshi | Ifanele ukucubungula ukudla, uchungechunge lwezindawo zokudlela kanye nezinye izimboni. |
Izimo zokugcina | I-Cryopreservation ngaphansi kuka -18 ℃ |
Inyama eqandisiwe ibhekisela enyameni ehlatshiwe, epholile ngaphambi kokukhipha i-asidi, iqhwa, bese igcinwa ngaphansi kuka -18°C, kanti izinga lokushisa lenyama ejulile lingaphansi kuka -6°C.Inyama eqandisiwe yeqophelo eliphezulu ivamise ukuba yiqhwa ku -28°C kuya ku-40°C, futhi ikhwalithi yenyama kanye nokunambitheka akuhlukile kakhulu kulokho kwenyama esanda kuzalwa noma ebandayo.
Uma iqhwa emazingeni okushisa aphansi, ikhwalithi nokunambitheka kwenyama kuzohluka kakhulu, yingakho abantu abaningi becabanga ukuthi inyama efriziwe ayimnandi.Nokho, lezi zinhlobo ezimbili zenyama eqandisiwe zineshalofu isikhathi eside, ngakho zisetshenziswa kakhulu.
Ithonya le-Microbial
1. Ukusabela okuhlukahlukene kwamakhemikhali ezinto eziphilayo kunciphisa ijubane ngesikhathi se-metabolism yezinto ezincane emazingeni okushisa aphansi, ngakho ukukhula nokukhiqizwa kwama-microorganisms kancane kancane kuncipha.
2. Lapho izinga lokushisa lehla ngaphansi kwendawo yokuqandisa, amanzi ezinto ezincane eziphilayo nendawo ezungezile aba yiqhwa, okwandisa i-viscosity ye-cytoplasm, akhuphule ukugxila kwe-electrolyte, aguqule inani le-pH kanye nesimo se-colloidal samaseli, futhi amaseli.Ukulimala, lezi zinguquko zemvelo zangaphakathi nangaphandle ziyimbangela eqondile yokuvimbela noma ukufa kwe-microbial metabolism.
Umthelela wama-enzyme
Ukushisa okuphansi akuvimbi ngokuphelele i-enzyme, futhi i-enzyme isengakwazi ukugcina ingxenye yomsebenzi wayo, ngakho-ke i-catalysis empeleni ayimi, kodwa ihamba kancane kakhulu.Isibonelo, i-trypsin isenokusabela okubuthakathaka ku--30 ° C, futhi ama-enzyme e-lipolytic asengadala i-fat hydrolysis ku -20 ° C.Ngokuvamile, umsebenzi we-enzyme ungancishiswa ube yinani elincane ku--18 ° C.Ngakho-ke, ukugcinwa kwezinga lokushisa eliphansi kungandisa isikhathi sokulondoloza inyama.
