NPAJ GELATIN YOG DAB TSI THIAB YUAV SIV LI CAS?
Cov nplooj gelatin (cov ntawv gelatin)yog ib qho flake nyias, pob tshab, feem ntau muaj nyob rau hauv peb qhov kev qhia, 5 grams, 3.33 grams thiab 2.5 grams. Nws yog ib qho colloid (coagulant) rho tawm los ntawm cov ntaub so ntswg ntawm cov tsiaj. Lub ntsiab tivthaiv yog protein thiab xim yog pob tshab; nws yuav tsum tau tsau rau hauv dej txias ua ntej siv, thiab nws yuav yaj saum toj no 80 ° C. Yog tias cov kua qaub nyob rau hauv cov tshuaj yog siab dhau, nws tsis yooj yim rau khov, thiab cov khoom tiav lawm yuav tsum tau khaws cia rau hauv qhov chaw txias, thiab qhov saj muaj zog zoo heev thiab elasticity.
Cov nplooj gelatin muaj 18 hom amino acids thiab 90% collagen, uas nplua nuj nyob rau hauv kev noj qab haus huv thiab kev zoo nkauj. Lawv muaj kev tiv thaiv colloidal zoo heev, kev ua haujlwm ntawm qhov chaw, viscosity, zaj duab xis tsim, ncua, buffering,infiltration, stability thiab yooj yim soluble hauv dej.
Cov nplooj gelatin tsis muaj ntxhiab tsw, yog li lawv feem ntau siv rau hauv kev tsim cov khoom qab zib zoo. Lawv yog cov khoom xyaw tseem ceeb rau cov khoom qab zib Western, xws li mousse cake, tiramisu, pudding, thiab jelly.
Cov ntawv gelatin yog cov khoom xyaw khov thiab yog qhov kev xaiv zoo tshaj plaws rau kev ua mousse ncuav mog qab zib. Vim tias cov jelly thiab mousse ua los ntawm hmoov isinglass muaj qhov saj me ntsis ntawm isinglass, nws yuav cuam tshuam rau qhov saj me ntsis, tab sis cov ntawv gelatin yuav tsis cuam tshuam, vim nws tsis muaj xim thiab tsis muaj saj, yog li feem ntau cov khw noj mov kim heev siv cov ntawv gelatin.
Dosage ntawm gelatindaim ntawvsCov lus qhia dav dav: Qhov piv txwv ntawm cov tshuaj siv yog 1:40, uas yog, 1 daim ntawv gelatin 5 grams tuaj yeem ua rau 200 grams ntawm cov kua dej sib xyaw ua ke, tab sis qhov piv no tsuas yog qhov piv txwv yooj yim ntawm cov kua dej uas tuaj yeem sib xyaw ua ke; yog tias koj xav ua jelly rau pudding, feem ntau pom zoo kom ua haujlwm ntawm qhov piv ntawm 1:16; yog tias ua mousse, feem ntau siv 10 grams ntawm cov ntawv gelatin rau 6 nti thiab 20 grams rau 8 nti.
Yuav siv li casnplooj gelatin: Ua ntej siv, muab dej txias rau hauv (dej khov zoo tshaj thaum nws kub). Tom qab tshem nws tawm, nias cov dej tawm, do thiab yaj rau hauv dej kub, thiab nchuav cov kua gelatin uas yaj lawm thiab do kom sib npaug rau hauv cov kua uas xav tau kom sib xyaw.
Cov Lus Qhia:1. Sim tsis txhob muab cov ntawv gelatin sib tshooj thaum nws tsau, thiab tshem cov dej tawm tom qab nws tsau; 2. Qhov kub yuav tsum tsis txhob siab dhau thaum lub sijhawm ua kom sov, txwv tsis pub qhov gelatinization effect yuav txo qis. 3. Thaum cov ntawv gelatin nyob rau hauv daim ntawv kua, cia nws txias rau kev siv. Lub sijhawm no, them sai sai rau lub sijhawm. Yog tias nws ntev dhau, nws yuav rov khov, uas yuav cuam tshuam rau qhov zoo ntawm cov khoom tiav. 4. Khaws cia rau hauv qhov chaw qhuav, txwv tsis pub nws yuav tau txais dej noo yooj yim.
