Tsev

1. Ua ntej nrog lub ntim ntawm cov dej qub los yog me ntsis ntxiv (cov kua nplaum dav dav thiab cov dej sib piv ntawm 1 mus rau 1.2-3.0, nws yog qhov zoo tshaj plaws los siv dej sov) kom ntub cov kua nplaum rau ob peb teev los yog li ntawd, ua kom cov nplaum nplaum mos. , thiab tom qab ntawd rhaub rau li 75 degrees, ua kom nws ua kua nplaum tuaj yeem siv tau.
2. Qhov piv ntawm cov kua nplaum thiab dej yuav tsum tau txiav txim siab raws li qhov xav tau viscosity.Cov dej ntau dua, qis viscosity, thiab dej tsawg dua, ntau dua viscosity.Thaum rhuab lub gelatin, qhov kub yuav tsum tsis txhob siab dhau, vim hais tias qhov kub tshaj 100 degrees yuav txo cov viscosity vim molecular degradation, thiab cov gelatin yuav muaj hnub nyoog thiab deteriorate.
3. Muaj cov kab ua paug hauv kev siv cov kua nplaum, yog li nws yuav tsum tau sib tov nrog dej thaum siv los kho viscosity thiab fluidity.da dej kub yuav tsum tau siv los ua kom sov cov kua nplaum.Nws yog kiag li tsis pub kom sov cov kua nplaum ncaj qha rau hauv lub thawv.
4. Cov gelatin yuav tsum tau khaws cia rau hauv qhov kub thiab txias ua ntej nws tuaj yeem siv tau.Yog li ntawd, thaum dej yuav tsum tau siv, qhov kub thiab txias ntawm cov dej thiab colloid yuav tsum yog tib yam, thiab dej txias yuav tsum tsis txhob ntxiv.Thaum siv gelatin, qhov ceev yuav tsum ceev thiab sib xws.Kho cov dej thiab gelatin kom tau qhov xav tau viscosity.
