Kev haus dej haus cawv

Raws li kev solubility ntawm cov dej qab zib, nws yog qhov zoo tshaj plaws los siv dej sov ntawm ib ncig ntawm 60 degree rau kev sib tov. Qhov no yog vim hais tias cov khoom noj khoom haus muaj nyob rau hauv cov khoom noj khoom haus muaj feem ua rau decomposition thiab spoilage ntawm qhov kub thiab txias, xws li vitamin C yaj hauv 100 degree dej, uas poob 83 feem pua ​​​​hauv 10 feeb; Protein raws li cov dej qab zib xws li mis hmoov yuav cuam tshuam los ntawm qhov kub thiab txias, thiab cov protein yuav hloov los ntawm lub xeev sol mus rau lub xeev gel, uas ua rau cov av qis, uas yuav cuam tshuam rau cov khoom noj siv mis.
Vim yog qhov nrawm nrawm ntawm cov vitamins B nyob rau hauv lub teeb pom kev zoo, nws raug nquahu kom siv khob iav tsaus lossis khob opaque thaum npaj cov dej haus uas muaj cov vitamins B1 thiab B6 (xws li kua txiv hmab txiv ntoo) kom txo cov zaub mov poob; Cov tshuaj aqueous ntawm vitamin C yuav sai sai oxidize hauv huab cua. Yog li ntawd, thaum npaj cov dej haus uas muaj vitamin C siab (xws li kua txiv kab ntxwv thiab kua txiv qaub), nws yog ib qho tseem ceeb uas yuav tsum tau haus dej kom sai li sai tau thiab tsis txhob cia lawv ntev heev.
Nws yog qhov zoo tshaj plaws tsis txhob sib tov nrog dej kub vim hais tias cov khoom noj khoom haus muaj nyob rau hauv cov dej qab zib yog nquag decomposition thiab spoilage ntawm qhov kub thiab txias. Kev tshawb fawb tau pom tias ntawm 100 degree, vitamin C yaj hauv dej poob 83 feem pua ​​​​hauv 10 feeb; Txawm li cas los xij, cov dej haus uas muaj protein ntau xws li mis hmoov yuav raug cuam tshuam los ntawm qhov kub thiab txias, thiab cov protein yuav hloov los ntawm lub xeev sol mus rau lub xeev gel, uas ua rau cov sediment thiab cuam tshuam rau qhov zoo. Yog li ntawd, raws li kev solubility ntawm cov dej haus, nws yog qhov zoo tshaj plaws los siv dej sov ntawm ib ncig ntawm 60 degree rau kev sib tov.
Tsis tas li ntawd, vim yog qhov decomposition sai ntawm vitamin B nyob rau hauv tshav ntuj, nws raug nquahu kom siv khob iav tsaus lossis khob opaque thaum npaj cov dej haus uas muaj cov vitamins B xws li B1 thiab B6 (xws li jujube kua txiv) kom txo cov as-ham poob; Vitamin C aqueous daws tuaj yeem oxidize sai hauv huab cua. Thaum npaj cov dej haus uas muaj vitamin C (xws li kua txiv kab ntxwv thiab kua txiv qaub), tsis txhob cia nws zaum ntev dhau ua ntej haus.
