Xim Hloov Ntawm Dehydrated Qej Flakes

Lub cev qhuav dej qej slices yuav xim av rau qee yam thaum lub sijhawm ziab. Hauv kev tsim khoom lag luam, sulfite thiab lwm yam xim-tiv thaiv cov neeg ua haujlwm feem ntau yog siv rau kev kho ua ntej-soaking. Thaum lub sij hawm soaking, sulfite tuaj yeem cuam tshuam kev ua haujlwm ntawm cov enzymes cuam tshuam. Cov SO2 tso tawm tuaj yeem txo cov quinone rau phenol, thiab tom qab ntawd ua rau cov pa roj carbonyl pawg, yog li tiv thaiv cov polymerization ntawm carbonyl compound thiab tswj cov tshuaj tiv thaiv browning, kom cov khoom muaj xim zoo dua, tab sis kev siv ntau dhau ntawm sulfite yuav ua rau cov khoom lag luam. Cov seem ntawm SO2 yog siab dhau, yog li ua rau tib neeg noj qab haus huv.
Tam sim no, nyob rau hauv kev lag luam ntawm qhuav qej slices, sulfite tshuaj feem ntau yog siv los pre-soak lub qej slices kom tau lub cev qhuav dej qej slices nrog zoo xim. Thaum soaking nyob rau hauv sodium sulfite nyob rau hauv qhov sib txawv kub kub, lub L * thiab ib tug dehydrated qej slices Lub * qhov tseem ceeb tsis hloov loj, thaum lub b * tus nqi nce me ntsis nrog rau qhov kub thiab txias, thiab cov xim ntawm qej slices yog me ntsis. daj daj. Thaum lub hlais tuab yog 3 hli, qhov ΔE * tus nqi ntawm qej slices yog qhov loj tshaj plaws ntawm 40 degree, qhia tias cov xim ntawm lub cev qhuav dej qej slices nyob rau lub sij hawm no yog qhov txawv tshaj plaws ntawm cov xim ntawm lub cev qhuav dej qej slices soaked ntawm 20 degree. ; Thaum cov hlais tuab yog 5 hli, qhov ΔE * qhov tseem ceeb me dua, Nws qhia tau hais tias thaum lub ntsuas kub qis dua 50 degree, qhov sib txawv ntawm qhov kub thiab txias tsis muaj qhov cuam tshuam me ntsis rau cov xim ntawm lub cev qhuav dej qej slices.
