Calcium works with hydrocolloids like sodium alginate and gellan to form thin films around liquid ingredients. Description: Formalin or other aldehyde fixation forms protein cross-links that mask the antigenic sites in tissue specimens, thereby giving weak or false negative staining for immunohistochemical detection of certain proteins. Essentially, if you remove the H+ portion of citric acid and replace it with Na+ ions, you get sodium citrate. This is called constructed cheese in modernist cuisine. Examine the different forms of phosphate salts and some buffering system pH ranges. But these ions also difficult the proper hydration of the hydrocolloids which is necessary to form a gel.
