How to prepare lime juice

Due to the chemical and alkaline properties of lime powder, this substance itself should not enter the body directly or come into direct contact with the skin of the hands, but lime water should be prepared and used for various applications. To prepare lime water, we must pour 1 kg of hydrated lime in 5-6 glasses of water and after stirring, give enough time for the lime powder to settle. Since hydrated lime does not dissolve in water; Therefore, it settles at the bottom of the container and a white or milky liquid remains above it, which is called lime water. Lime water has the properties that we need from hydrated lime for edible applications.
