Sezvatinoziva tese, yogati inowanzo shandiswa sezvinowedzera zvekudya, uye gelatin ndeimwe yacho.
Gelatin inotorwa kubva kuprotein yecollagen inowanikwa zvakanyanya muganda remhuka, mutsinga nemapfupa. Iprotein yakasanganiswa ne hydrolyzed kubva ku collagen munyama yemhuka kana mu epidermal tishu. Mushure mekunge ganda remhuka kana mapfupa zvarapwa, gelatin, chigadzirwa che collagen chakasanganiswa ne hydrolyzed, chinogona kuwanikwa. Nemamwe mashoko, collagen inoshandurwa kuita chigadzirwa chinonyungudika mumvura mushure mekutyoka kwechikamu che intermolecular bonds nekuda kwe reinversion heating hydrolysis reaction.
Musiyano uripo pakati peganda reA neganda reB unokonzerwa nemusiyano uripo pakati pemaamino acids ane acidic nealkaline mugelatin nekuda kwekushandiswa kwakasiyana kwejeli. Nesimba rakafanana rejeli, jeli reB rine viscosity yakakura kupfuura jeli reA. Gelatin hainyungudike mumvura inotonhora, asi inogona kunwisa mvura nekuzvimba kusvika ka5-10. Gelatin inowedzera granularity uye kudzikira kwekugona kunwisa mvura. Gelatin inova gelatin solution mushure mekudziya tembiricha inodarika melting point yegelatin, uye gelatin inova jeli mushure mekutonhora.
Sechinowedzera chikafu, gelatin inodyiwainoshandiswa zvakanyanya mukugadzira yogati. Gelatin inobatsira pakugadzirisa uye kukora. Mhinduro dzeGelatin dzinoita kuti yogati ive yakakora uye ive nyore kuichengeta.
Zvichienderana nekupatsanurwa kweyogati, kushandiswa kwegelatin muyogati kunosanganisira zvinhu zvitatu:
1. Yogati yakasanganiswa: Chigadzirwa cheyogati yekare ndicho chinomiririra. Yogati yakasanganiswa chigadzirwa chisina kubviswa mumukaka mushure mekuvirisa. Gelatin inoita kuti zvigadzirwa zvive nemaumbirwo akatsetseka ayo zvimwe zvigadzirwa zvakaita sestachi dzakagadziriswa neasidhi zvakatadza kupa.
2. Yogati yakasanganiswa: Zvigadzirwa zvakajairika pamusika, zvakaita seGuanyiru, Changqing, Biyou, nezvimwewo, zvese zvinosanganiswa neyogati yakasanganiswa. Muzvigadzirwa zvakadaro, gelatin inonyanya kushandiswa sechinokora, uye pakutanga kwekugadzirwa, tinonyungudutsa gelatin mu65 ℃. Huwandu hwegelatin huri pakati pe0.1-0.2%. Gelatin inodzivirira homogenization uye kumanikidzwa kwekupisa panguva yekugadzira yogati, zvichipa chigadzirwa viscosity yakakodzera.
3. Kunwa yogati: Kunwa yogati kunoreva kuti tinoderedza viscosity yechigadzirwa kuburikidza nekuita kuti chive chakafanana mushure mekuvirisa. Nekuda kwekudzikira kweviscosity, inofanirwa kushandisa colloid kuti ive nechokwadi chekugadzikana kwechigadzirwa uye kuderedza kupatsanurwa kweyogati mukati menguva yakatarwa. Izvi zvinogona kuitwawo nedzimwe colloid.
Mukupedzisa, kuwedzera gelatin muyogati kunogona kudzivirira kupatsanurwa kwe whey, kuvandudza kurongeka uye kugadzikana kwechigadzirwa chapera, uye zvakare kuita kuti chionekwe zvakanaka, kunaka uye magadzirirwo akanaka. Gelken inokwanisa kupa gelatin yemhando yepamusoro yeyogati.
