Dab tsi yog qhov txawv ntawm industrial gelatin thiab edible gelatin?

1. Qhov zoo sib xws ntawm industrial gelatin thiab edible gelatin:

Ob qho tib si noj tau thiab muaj gelatin yog cov proteins.

2.Qhov txawv ntawm industrial gelatin thiab edible gelatin:

Lub extraction ntawm edible gelatin thiab industrial gelatin tsis muaj teeb meem.Qhov sib txawv tseem ceeb yog nyob rau hauv cov khoom siv raw.Lub edible gelatin yog muab rho tawm los ntawm cov tsiaj tawv nqaij tshiab thiab cov pob txha.Industrial gelatin siv cov ntaub ntawv raw xws li tawv tawv.

Noj gelatin, raw cov ntaub ntawv yog tshiab, tsis-spoilage, tsis muaj tshuaj kho mob, tsiaj tawv nqaij (npua, nyuj thiab lwm yam tsiaj tawv nqaij yog nplua nuj nyob rau hauv collagen) ua, boiled tawm ntawm cov kua nplaum.Ob qho khoom siv raw thiab cov khoom kawg yog huv si.Gelatin muaj nuj nqicollagen.

Muaj gelatintsis belongs rau qeb ntawmzaub mov additives.Ua ntej tshaj plaws, cov khoom siv raw ntawm cov khoom siv gelatin tsis ua raws li cov qauv kev noj qab haus huv.Qhov thib ob, cov txheej txheem ua tsis tau raws li qhov yuav tsum tau ua ntawm kev nyiam huv ntawm zaub mov.Cov khoom lag luam muaj cov hlau hnyav hnyav xws li arsenic, mercury, lead lossis residual chemical Cheebtsam, uas yeej tsis noj tau.

Tom ntej no, peb xav qhia koj txog kev tsim txom ntawm kev lag luam gelatin rau tib neeg lub cev.Qhov teeb meem ntawm kev lag luam gelatin yog plaub hau zoo nkauj.Cov gelatin tau muab rho tawm los ntawm cov tawv nqaij thiab cov pob txha thiab tuaj yeem siv rau jelly thiab ice cream, khoom qab zib.Muaj gelatin muab rho tawm los ntawm cov tawv tawv uas muaj ntau cov hlau hnyav xws li txhuas, mercury, rau tib neeg lub cev lub siab, lub raum, tawv nqaij, ntshav, thiab lwm yam uas yuav ua rau cov kab mob xws li ntshav qab zib, nephritis, neuritis thiab txawm tias mob qog noj ntshav. tib neeg lub cev tom qab ncav cuag ib qho nyiaj ntawm nws.

Yog li yuav ua li cas thiaj paub qhov txawv ntawm cov khoom lag luam gelatin thiab cov khoom noj khoom haus gelatin?

Koj tuaj yeem ua nws thawj zaug hauv peb txoj kev.

1. Cov khoom lag luam gelatin feem ntau yog cov khoom tsis zoo, ntau impurities, me viscosity thiab toughness, yog li nws yog qhov tshwj xeeb tshaj plaws.Yog tias koj pom saum toj no hauv cov khoom koj yuav, koj tuaj yeem txiav txim siab tias muaj gelatin ntxiv.

2. Cov khoom lag luam gelatin, feem ntau muaj cov xim ci.Vim tias cov khoom noj khoom haus gelatin yog pob tshab, dawb, thiab huv heev, thaum muaj gelatin yog tag nrho ntawm impurities.Yog tias muaj gelatin siv, cov tuam txhab lag luam yuav ntxiv cov tsw qab, thiab cov xim pleev xim rau daim npog qhov tsis huv, yog li cov xim ci dua, qhov yuav ua tau los ntawm kev lag luam gelatin.

3.Cov khoom ua los ntawm cov khoom siv gelatin feem ntau tsis zoo, cov khoom siv, kev siv tshuab thiab ib puag ncig vim tias lawv tau ua los txo cov nqi.
