Tekinoroji yekugadzira hove yeCollagen
Collagen ndeimwe yemapuroteni makuru anoumba nhengo dzinobatanidza zvinhu zvipenyu. Mumakumi emakore achangopfuura, collagen yave ichishandiswa zvakanyanya muindasitiri yechikafu, yemishonga, yezvizoro, uye yezvekurapa. Kunyange zvazvo collagen yemombe nenguruve yaimbova sosi huru, collagen yehove ikozvino yava imwe nzira yakakurumbira. Zvikonzero zvakasiyana-siyana: kuwanikwa kwezvinhu zvakabikwa kubva mumarara eindasitiri yehove, njodzi yakaderera yezvirwere zvemhuka zvichienzaniswa nezvimwe mhuka dzinoyamwisa, uye kugamuchirwa kwakakura kwezvikamu zvehalal netsika munyika dzakasiyana-siyana. Chinyorwa chino chinotaura nezve tekinoroji yekugadzira collagen yehove, kubva pazvinhu zvakabikwa, matanho ekugadzirisa, nzira dzekubvisa, kusvika kuzvinhu zvemhando yepamusoro nematambudziko ekukura.
Mikana uye Manyuko eHove Collagen Raw Materials
Collagen yehove inowanzo kuwanikwa kubva muzvikamu zvehove zvinowanzoonekwa semarara, zvakaita seganda, makwati, mapfupa, uye dundira rekushambira. Ganda rehove chinhu chakakurumbira nekuda kwehuwandu hwaro hwakawanda hwecollagen uye nyore kugadziriswa. Makwati nemapfupa akapfumawo mucollagen, asi anoda nzira yakanyanya yekubvisa mineral nekuda kwehuwandu hwayo hwecalcium nephosphate. Kushandisa marara aya kunowedzera kukosha kubazi rehove ukuwo kuchideredza mutoro wezvakatipoteredza unokonzerwa nekurasa marara.
Rudzi rwehove dzinoshandiswa runogona kukanganisa hunhu hwecollagen inobuda. Hove dzemvura inotonhora dzinowanzo gadzira collagen ine kugadzikana kushoma kwekupisa kupfuura hove dzemunzvimbo dzinopisa nekuda kwekushanduka kwavo nekupisa kwekunze. Kugadzikana uku kwekupisa kwakakosha, kunyanya kune zvinoshandiswa zvinoda kudzikamiswa nekupisa, zvakaita se gelatin raw materials kana mamwe maformula ekushongedza.
Nheyo dzekutanga dzekugadzira Collagen
Kazhinji, kugadzirwa kwecollagen yehove kunovavarira kuparadzanisa collagen kubva mumatishu, kubvisa zvinhu zvisiri zvecollagen (mafuta, mamwe mapuroteni), uye kuwana chigadzirwa chakachengeteka uye chakasimba chinosangana nezvinodiwa zvekushandisa. Collagen inobuda inowanzo unganidzwa muzvikamu zviviri zvikuru: Acid Soluble Collagen (ASC) nePepsin Soluble Collagen (PSC). ASC inowanikwa kuburikidza nekubvisa acid, nepo PSC ichishandisa rubatsiro rwema enzymes (pepsin) kuwedzera goho nekutyora mamwe ma cross-link pasina kukuvadza zvakanyanya chimiro che triple helix.
Pamusoro pezvo, collagen hydrolysis inowanzoitwa mumaindasitiri kugadzira collagen peptides ine huremu hudiki, iyo inonyungudika mumvura uye iri nyore kugadzira zvinwiwa zvinoshanda kana zvekudya zvinovaka muviri.
Danho rekutanga: Kuchenesa nekugadzirira
Danho rekutanga rinoona kunaka kwekupedzisira kwecollagen. Zvinhu zvitsva zvinofanira kubatwa nekukasika patembiricha yakaderera kudzivirira kuparara kwemapuroteni nehutachiona nema enzymes endogenous. Maitiro akajairika anosanganisira:
1. Kuronga nekugeza kubvisa ropa, tsvina uye zvasara zvenyama.
2. Kucheka kana kuderedza saizi kuti nzvimbo yepamusoro iwedzere uye kuti kuburitsa kubudirire.
3. Kuchengetera zvinhu zvinotonhora (zvichitonhora kana kuti zvakaomeswa nechando) kana zvikasagadziriswa nekukasika, kuchengetedza collagen yakakwana.
Kuchena kwemaitiro kwakakosha nekuti collagen inowanzo shandiswa muzvigadzirwa zvinosangana nemuviri kana zvinonwiwa, saka mitemo yehutsanana uye kudzora kusvibiswa kweganda zvinofanirwa kuve zvakasimba.
Kubvisa mafuta uye Kubvisa mapuroteni
Zvinhu zvakaita seganda rehove zvine mafuta anogona kukanganisa kubviswa kwemafuta, kukonzera kunhuwa, uye kukurumidzisa kunhuwa. Nokudaro, kubvisa mafuta (kubvisa mafuta) kunoitwa, semuenzaniso nekunyika mune zvinonyungudutsa zvekudya kana nzira dzemvura/lipase enzyme, zvichienderana nekushandiswa kwakanangana nemitemo.
Kubvisa mapuroteni kunozoitwa kuderedza mapuroteni asiri ecollagen. Nzira inowanzo shandiswa inosanganisira kunyudzwa mu diluted alkaline solution (semuenzaniso, low-concentration NaOH) kwemaawa akati wandei kusvika kumazuva, nekuchinja kwemhinduro nguva nenguva. Danho iri rinobatsira kunyungudutsa globular proteins ne pigments, asi rinofanira kudzorwa zvakasimba kudzivirira kukuvadza collagen.
Kubviswa kwesimba remuviri (Zvikero neMapfupa Chete)
Kana zvinhu zviri mumakwara kana mapfupa, kubviswa kwemamineral kunodiwa kuti zvicherwa zvibviswe, kunyanya hydroxyapatite. Maitiro aya anowanzoitwa uchishandisa weak acid solution yakaita seEDTA kana organic/inorganic acids pasi pemamwe mamiriro. Kubviswa kwemamineral kwakakodzera kunoita kuti pave necollagen matrix iri nyore kubvisa uye inovandudza kuchena kwechigadzirwa.
Kubviswa kweCollagen: Nzira dzeAcid neEnzyme
1. Kubvisa Asidhi (ASC)
Kubvisa asidhi kunowanzo shandiswa acetic acid yakasanganiswa. Chinangwa ndechekusunungura chimiro che connective tissue, zvichiita kuti collagen inyungudike zvakanyanya. Maitiro aya anoitwa patembiricha yakaderera (kazhinji iri pasi petembiricha inobvisa collagen) kuchengetedza chimiro che triple helix. Mushure mekunyikwa nekukurunga kwenguva yakatarwa, mvura inobviswa inoseferwa kana kutenderedzwa kuti iparadzanise zvakasara zvakasimba.
Zvakanakira nzira iyi ndezvekuti iri nyore uye inodhura zvishoma. Zvisinei, goho rinogona kuderera nekuti collagen ine connection yakasimba hainyungudutswi nyore nyore neasidhi chete.
2. Kubviswa kweEnzyme Inobatsira (PSC)
Munzira yePSC, enzyme pepsin inowedzerwa mumamiriro ezvinhu ane acidic. Pepsin inobatsira kupatsanura nzvimbo dzisiri dzehelical (telopeptides) dzinowanzo shanda senzvimbo dzinobatanidza, zvichiita kuti collagen inyungudike zviri nyore. Nzira iyi inowanzo buritsa goho rakawanda kupfuura ASC uye inogona kuvandudza kuenderana kwekuburitsa kubva muzvinhu "zvekare" kana zvakawanda zvakabatana.
Matambudziko ePSC imutengo we enzyme uye kudiwa kwekudzora maitiro ekudzivirira kuora kwakanyanya kunoderedza kunaka.
Kucheneswa: Kunaya kwemvura, Dialysis, uye Kuomesa
Kana collagen yabviswa, danho rinotevera nderekuchenesa. Imwe nzira inowanzo shandiswa ndeyekutsvaira munyu, uchishandisa munyu (semuenzaniso, NaCl) kuti collagen ibude mumvura. Precipitate yacho inozopatsanurwa ne centrifugation yozonyungudutswazve mu dilute acid solvent.
Tevere, dialysis inoitirwa kubvisa munyu, acids, uye mamwe mamorekuru madiki. Dialysis inotora mazuva akati wandei, ichichinja mvura kana buffer nguva dzose. Danho rekupedzisira nderekuomesa, kazhinji uchishandisa freezer-drying kuchengetedza chimiro checollagen uye kugadzira upfu hwakagadzikana.
Padanho remaindasitiri, kuomesa kunogona kuitwawo nekupfapfaidza, asi kunofanirwa kugadzirwa nenzira yekuti tembiricha yekushanda kwechinhu isakuvadze collagen kana kukonzera kudonha kwakanyanya kweganda.
Kugadzirwa kweCollagen Peptide (Hydrolysis)
Kuti pagadzirwe ma collagen peptides, collagen inobviswa kana kuti collagen yacho inonyungudutswa uchishandisa ma enzymes chaiwo eprotease. Maitiro e hydrolysis anogadzira ma peptide madiki, anonyunguduka ane kunaka uye ruvara rwakasununguka kana akacheneswa zvakanaka. Ma peptide aya anoshandiswa zvakanyanya muzvinwiwa zvinoshanda, zvekudya zvinovaka muviri, uye muzvinobatanidza chikafu.
Kudzora kwakakosha padanho iri kunosanganisira mwero we hydrolysis, molecular weight profile, uye kubviswa kwemunhuwi wehove kuburikidza nekuchenesa kwakawedzerwa senge activated carbon kana mamwe matekiniki ekubvisa munhuwi.
Kuedzwa Kwemhando Yepamusoro uye Kuchengetedzeka
Kolajeni yakanaka yehove inofanira kusangana nezvinodiwa zvemuviri, zvemakemikari, uye zvehutachiona. Mimwe miedzo yakajairika inosanganisira:
- Huremu hwemapuroteni nemvura, kuitira kuti chigadzirwa chive chakasimba.
– Amino acid profile, kunyanya huwandu hweglycine, proline, uye hydroxyproline izvo zvinoratidza collagen.
- Kusimba uye kunyungudika, zvakakosha pakushandiswa kwechikafu uye kushongedza.
– Kuongororwa kwezvirwere zvidiki (TPC, coliform, mamwe majekiseni) kuti zvionekwe kuti zvakachengeteka here.
– Kuongororwa kwesimbi ine simba, kunyanya kana zvinhu zvakabikwa zvichibva mumvura dzine njodzi yekusvibiswa.
Uyezve, zvinhu zvakaita semunhuwi, ruvara, uye kuravira zvakakoshawo. Zvigadzirwa zvakawanda zve collagen yehove zvinoda munhuwi mudiki kuti zviite nyore kushandisa muzvigadzirwa zvakagadzirira kudyiwa.
Matambudziko uye Nzira dzeKubudirira
Kugadzirwa kwecollagen yehove kunosangana nematambudziko akati wandei: kusiyana kwemwaka muzvinhu zvakagadzirwa, hwema hwehove hunozivikanwa, kugadzikana kwekupisa kwakaderera kana tichienzanisa necollagen yemhuka dzinoyamwisa, uye mari inodiwa pakuchenesa kuti uwane mhando yepamusoro. Panguva iyi, matekinoroji ari kuramba achichinja, akadai sekushandisa ultrasonic-assisted extraction, high pressure extraction, kana enzyme combinations kuwedzera goho uye kuderedza kushandiswa kwemakemikari.
Kuenderera mberi, nzira yekuti "hapana marara" muindasitiri yehove inogona kuwedzera kugadzirwa kwecollagen sechigadzirwa chakakosha. Nekudzora kwakasimba kwemhando yepamusoro uye hunyanzvi hwekugadzira, collagen yehove ine mukana wakakura wekuva chinhu chinotungamira mukudya kunoshanda, zvizoro zvisingakuvadzi nharaunda, uye zvinhu zvipenyu zvinogara kwenguva refu.
Penutup
