Njengesixhobo esibalulekileyo sokongezwa kokutya kunye nesemizi-mveliso, uhlobo lwesayensi kunye nexabiso lokusetyenziswa kwegelatin kufuneka kuhlolisiswe ngokunzulu. Eli nqaku lihlola ngokucwangcisiweyo imithombo yayo yezinto ezikrwada, iipropati ze-physicochemical, iindawo zokusetyenziswa, kunye nobuchwepheshe bemveliso.

I. Imithombo yezinto eziluhlaza kunye nemigaqo yemveliso

I-Gelatin yimveliso ye-collagen eguqulwe ubushushu, efumaneka ikakhulu kwi-collagen components kwizicubu ezidityanisiweyo zezilwanyana. Imveliso yemizi-mveliso idla ngokusebenzisa amathambo, iileya zesikhumba, kunye nemisipha evela kwizilwanyana ezincancisayo ezifana neehagu kunye neenkomo. Ngokusebenzisa unyango lwe-acid-base okanye i-enzyme hydrolysis, i-collagen iyakhutshwa ize iguqulwe ubushushu ukuze kufunyanwe i-gelatin. Ukususwa kwe-polymerization yesakhiwo se-collagen ngexesha lokuveliswa kubalulekile ekwenzeni iipropati ezikhethekileyo ze-gelatin.

II. Iimpawu zeFizikokhemikhali

1. Iipropati Zomzimba
   I-Gelatin ibonakala njenge-solid ekhanyayo engenambala ukuya kwephuzi elikhanyayo, ekhoyo kwi-powder, flake, okanye kwi-granular. Ubunzima bayo be-molecular buphakathi kwe-50,000–100,000 Dalton, enobunzima be-1.3–1.4 g/cm³. Ibonisa iimpawu ze-electrolyte eziqhelekileyo ze-amphoteric, kunye ne-isoelectric point (pI) phakathi kwe-pH 4.8–5.2.
2. Ukuziphatha koxinzelelo lwe-hydration
   Indlela iGelatin evuvuka ngayo emanzini ilandela ithiyori kaFlory-Rehner: kumaqondo obushushu aphantsi, yenza inethiwekhi yejeli emanzi, ngelixa ukufudumala okungaphezulu kwama-35°C kubangela utshintsho oluvela kwi-helix ukuya kwi-coil, nto leyo edala i-thermal reversible sol. Le ndlela isuka kwisakhiwo se-triple-helix esenziwe yi-glycine-proline-hydroxyproline repeating sequences kwi-molecule chains zayo.

III. Iimpawu zokusebenza kunye nosetyenziso

1. Ishishini lokutya
   • Isilungisi seRheology: Yenza izakhiwo zenethiwekhi ezinemilinganiselo emithathu, inika i-elastic modulus (1–10 kPa) kwiitshizi kwaye ithintela ukukhula kwekristale yeqhwa (ubukhulu beenxalenye <50 μm) kwiidizethi ezikhenkcezisiweyo.
   • Isiqinisi se-Emulsion: Yehlisa uxinzelelo phakathi kweoyile namanzi ukuya kwi-10–20 mN/m, nto leyo ephucula uzinzo lwe-emulsion.
   • Iarhente yeGelling: Yenza iinethiwekhi zejeli ezinamandla e-200–300 Bloom, ezisetyenziswa ekunyibilikiseni imveliso yenyama kunye nokubumba iilekese.
2. Icandelo leMithi
   • I-Capsule Matrix: Ihambelana nemigangatho ye-USP, enexesha lokuqhekeka elingaphantsi kwemizuzu eli-15.
   • Indawo yePlasma: Uluhlu lokunqunyulwa kobunzima bemolekyuli yi-30–70 kDa.
   • Umthwali wezokuhambisa amayeza: Ivumela ukukhululwa okulawulwayo okunobuthathaka kwi-pH.
3. Izithambiso
   • Iarhente Yokwenza Iifilimu: Ivelisa iifilimu zokufumisa ezinobukhulu obuyi-1–5 μm.
   • Isiguquli seViscosity: Yonyusa i-viscosity yenkqubo ukuya kwi-500–2000 mPa·s.
   • Isiqinisi sokuSusa: Igcina amandla e-Zeta engaphezulu kwe-±30 mV.

IV. Uphuhliso kwiTekhnoloji yeMveliso yanamhlanje

Amashishini aphambili afana neGelken asebenzisa ubuchwepheshe obudibeneyo bokukhupha imveliso ukuphucula ukusebenza kwemveliso:

1. Ukwahlukana Ngomzimba: Iimembrane ze-Ultrafiltration (i-10 kDa yobunzima be-molecular cutoff) zivumela ukuhlukaniswa okuchanekileyo kobunzima be-molecular.
2. Ukufuma kwe-Ethanol Gradient: Uxinzelelo lotywala olulawulwayo (40–60%) luphucula ubumsulwa (>98%).
3. Ukuphucula i-Lyophilization: Igcina izakhiwo ezinemingxuma (imingxuma engaphezulu kwama-80%) kwaye ikhawulezisa isantya sokwakhiwa kwakhona (

V. Iindlela zeMarike kunye nemingeni

Imarike ye-gelatin yehlabathi ikhula ngokuthe chu kwi-5–6% ngonyaka, kunye neendlela eziphawulekayo:

• Iimveliso ezikumgangatho wamayeza ngoku zithatha i-35% yemarike.
• Ezinye iindlela zegelatin ezisekelwe kwizityalo ziphantsi kophuhliso olukhawulezileyo (isabelo sangoku <5%).
• I-Nano-gelatin (ubukhulu bamasuntswana angaphantsi kwe-100 nm) ibonisa ithemba kwiinkqubo zokuhambisa amayeza ezijoliswe kuzo.

Imingeni ephambili yeTekhnoloji:

1. Ukuphucula uzinzo lobushushu (ithagethi: ukunyamezelana kwama-80°C iiyure ezi-2).
2. Ukuqinisekisa ukhuseleko lweentsholongwane (amanqanaba e-endotoxin <0.25 EU/mg).
3. Ukuphuhlisa iinkqubo ezizinzileyo (ukunciphisa amandla ngama-30%).
