Yuav ua li cas txiav txim siab qhov zoo ntawm gelatin?

Raws li ib qho khoom xyaw tseem ceeb uas siv dav dav, gelatinua lub luag haujlwm tseem ceeb hauv ntau qhov chaw xws li khoom noj, tshuaj, thiab kev lag luam tshuaj lom neeg. Yuav kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm gelatin, nws yog ib qho tseem ceeb kom tsim thiab siv cov qauv kev tshuaj xyuas nruj. Ntawm no peb qhia cov qauv kev tshuaj xyuas ntawm gelatin kom meej.

1. Kev Tshuaj Xyuas Pom

Ua ntej tshaj plaws, ua qhov kev tshuaj xyuas pom ntawm gelatin. Cov gelatin zooyuav tsum pob tshab los yog pob tshab, nrog rau xim sib xws, thiab tsis muaj cov khoom tsis huv, npuas, thiab cov ntxhiab tsw txawv txawv. Yog tias muaj teeb meem xws li xim tsis sib xws, muaj cov khoom tsis huv, lossis npuas nyob rau hauv cov gelatin, nws yuav qhia txog teeb meem hauv cov txheej txheem tsim khoom lossis cov khoom siv raw tsis zoo, thiab yuav tsum tau kuaj xyuas ntxiv.

1. Kev Ntsuas Khoom Siv Physicochemical
2. Kev Ntsuas Viscosity:Qhov viscosity ntawm gelatin yog ib qho cim qhia tseem ceeb rau kev ntsuas nws qhov zoo. Nrog cov khoom siv xws li lub rotational viscometer, qhov viscosity ntawm gelatin tuaj yeem ntsuas tau kom ntseeg tau tias nws ua tau raws li cov qauv tsim nyog.
3. Kev Ntsuas Lub Zog Gel:Lub zog ntawm gelatin qhia txog nws lub peev xwm los tsim ib lub gel. Siv cov khoom siv xws li lub tshuab ntsuas kev ntxhib los mos, lub zog ntawm gelatin tuaj yeem ntsuas tau kom ntseeg tau tias nws muaj cov yam ntxwv zoo gelling.
4. Kev Ntsuas Kev Yaj:Cov gelatin zoo yuav tsum yooj yim yaj thiab ruaj khov hauv cov tshuaj. Los ntawm kev sim solubility, qhov solubility thiab kev ruaj khov ntawm gelatin tuaj yeem soj ntsuam tau.
                                            
   
   1. Cov Cim Qhia Txog Kab Mob Me Me

   Yuav kom ntseeg tau tias gelatin muaj kev nyab xeeb, yuav tsum tau kuaj xyuas nws cov cim qhia txog kab mob me me. Qhov no suav nrog kev kuaj pom cov kab mob me me xws li tag nrho cov kab mob me me, cov kab mob coliform, pwm, thiab poov xab, kom ntseeg tau tias gelatin tsis muaj kuab paug thiab ua tau raws li cov qauv kev huv.
   

   1. Kev Tshawb Pom Cov Hlau Hnyav thiab Cov Khoom Phom Sij

   Cov hlau hnyav thiab cov tshuaj lom uas muaj nyob hauv gelatin ua rau muaj kev phom sij rau tib neeg txoj kev noj qab haus huv. Yog li ntawd, nws yog ib qho tsim nyog los nrhiav cov hlau hnyav thiab cov tshuaj lom hauv gelatin, xws li txhuas, arsenic, mercury, thiab lwm yam, kom ntseeg tau tias lawv nyob hauv qhov chaw nyab xeeb.

    

   Xaus lus, qhov cov qauv tshuaj xyuas gelatin rau kev npog ntau yam, suav nrog kev pom, cov khoom siv physicochemical, cov cim qhia microbiological, nrog rau kev kuaj pom cov hlau hnyav thiab cov tshuaj lom neeg. Los ntawm kev ua raws li cov qauv no, qhov zoo thiab kev nyab xeeb ntawm gelatin tuaj yeem ua kom ntseeg tau, muab kev lees paub rau nws cov khoom tsim thiab siv hauv ntau yam lag luam.

    

   Lanpu Gelatin, nrog 30 xyoo kev tsim khoom gelatin, muab cov khoom tsim nyog thiab Gelatin ntshiab los ntawm cov txheej txheem QC nruj thiab cov txheej txheem los muab cov gelatin zoo rau cov neeg siv khoom thoob ntiaj teb hauvcov khoom noj khoom haus, khoom noj khoom qab zib, khoom noj mis nyuj, nrog rau daim ntawv thov hauv cov tshuaj ntsiav mos thiab tshuaj ntsiav tawv.
