Txhua tus neeg hla dej yeej paub tias qee hom ntses yuav tsum muaj cov xwm txheej tshwj xeeb, hauv qib uas tsim nyog ntawm acidity hauv dej. Yog tias cov dej tawv dhau, nws yuav tsum muaj acidified los ntawm kev qhia tshuaj. Yuav ua li cas yuav ua rau nws?
Cov Lus Qhia
Kauj ruam 1
Lub cev pH qib uas tsim nyog rau kev yug tsiaj feem ntau ntawm cov ntses thoob dej ntses yog li 6 txog 9. Cov ntsev uas txiav txim siab qhov nyuaj ntawm cov dej ua rau nws ntau alkaline, thiab cov organic zais ntawm ntses softer thiab ntau cov kua qaub.

Yog tias cov dej yog qhov nyuaj dhau, feem ntau nws ua tiav acidified los ntawm kev qhia qhov yuav tsum tau ntawm kev daws cov kua qaub: acetic, orthophosphoric thiab lwm yam. Ua ntej koj yuav tsum npaj ib qho kev daws teeb meem ntawm cov acid tsim nyog los ntawm kev ntxiv cov kua qaub poob los ntawm kev poob rau hauv dej (tsis yog piv txwv). Tom qab ntawd, siv cov raj xa dej, cov kua qaub yog ntxiv rau hauv dej, saib xyuas kev hloov pH siv ntsuas taw qhia. Rau txoj haujlwm no, nws yog qhov zoo dua yuav tsum siv ob peb litres dej los ntawm cov thoob dej yug ntses, ntxiv cov kua qaub, siv qhov ntsuas tsim nyog ntawm qib acidity, thiab tom qab ntawd, yog tias txhua yam ua tiav qhov tseeb, rov qab xa dej mus rau hauv lub thoob dej. Qhov no yuav tsum ua kom tsis txhob ua mob rau ntses yog tias dej ntau acidic.

Koj tuaj yeem nce cov acidity ntawm dej los ntawm kev ntxiv tov ntawm sodium dihydrogen phosphate NaH2PO4 lossis potassium KH2PO4. Cov ntsev no ua rau kom muaj cov tshuaj tiv thaiv acidic vim qhov pib ntawm cov txheej txheem hydrolysis. Txaus 20-30 gram ntawm ib qho ntawm cov ntsev twg hauv 100 liv dej kom tau txais cov kua dej me ntsis nrog pH theem ntawm 5, 8-6, 5.

Yog hais tias cov dej yog distilled lossis muaj ntsev me me heev rau nws, koj tuaj yeem sim ua kom acidify nrog peat decoction. Boil 10-20 g ntawm peat nyob rau hauv ib liter ntawm distilled dej rau 30 feeb. Tom qab ntawd lim cov kua thiab khaws cia rau hauv tub yees. Txhawm rau nce lub acidity, ntxiv cov kua rau hauv dej kom txog thaum nws hloov Golden xim av.
Kauj ruam 5
Yog tias, ntawm qhov tsis sib xws, koj xav txo qhov acidity ntawm dej, ntxiv cov tshuaj uas muaj cov tshuaj tiv thaiv alkaline rau nws, piv txwv li, sodium bicarbonate - ci dej qab zib. Yuav kom tau dej nrog cov tshuaj tiv thaiv me ntsis, nws txaus los ntxiv 3 rau 8 gram ntawm cov tshuaj rau hauv 100-thoob dej yug ntses.
