“…Other popular physiological solutions include α-modified Eagle’s [l] medium (α-MEM) and its variation, Dulbecco’s [m] modified Eagle’s medium (DMEM), which contain numerous bioorganic (alanine, aspartic acid, glycine, biotin, vitamin C, folic acid, riboflavin) and inorganic (CaCl 2 , KCl, NaCl, NaH 2 PO 4 ) components, 863 - 867 phosphate buffered saline (PBS) that contains only inorganic (CaCl 2 , MgCl 2 , KCl, KH 2 PO 4 , NaCl, NaH 2 PO 4 ) components 868 , 869 . Furthermore, artificial saliva, 870 - 872 synthetic urine 816 , 873 and simulated milk ultrafiltrate (SMUF) 874 - 877 solutions are available. They contain both bioorganic (e.g., xantan gum or sodium carboxymethylcellulose, sorbitol, etc.)…”

The present overview is intended to point the readers’ attention to the important subject of calcium orthophosphates. This type of materials is of special significance for human beings, because they represent the inorganic part of major normal (bones, teeth and antlers) and pathological (i.e., those appearing due to various diseases) calcified tissues of mammals. For example, atherosclerosis results in blood vessel blockage caused by a solid composite of cholesterol with calcium orthophosphates, while dental caries and osteoporosis mean a partial decalcification of teeth and bones, respectively, that results in replacement of a less soluble and harder biological apatite by more soluble and softer calcium hydrogenphosphates. Therefore, the processes of both normal and pathological calcifications are just an in vivo crystallization of calcium orthophosphates. Similarly, dental caries and osteoporosis might be considered an in vivo dissolution of calcium orthophosphates. Thus, calcium orthophosphates hold a great significance for humankind, and in this paper, an overview on the current knowledge on this subject is provided.

“…The estimated values were derived on the basis of the agreement between model calculation and experimental results in terms of pH, Ca 2+ activity and concentration. K ass and K sp values of ion species and compounds related to sodium hexametaphosphate (SHMP) were also included in EIS and DIS models and were shown in the accompanying paper (part II) (Gao et al, 2010).…”

“…[13,14] It is well known that the addition of ESs to milk and dairy products changes the calcium balance of the system, leading to a decline in calcium ion concentration, dissolution of CCP, and release of caseins from the micelles. [15,16] The decrease in free calcium ions and removal of CCP result in swelling and hydration of casein micelles. These phenomena have a great influence on turbidity and solubility of a dairy product.…”

This study aimed to investigate the effect of adding binary mixtures of disodium phosphate and tetrasodium pyrophosphate during milk powder production. Overall, the addition of disodium phosphate-tetrasodium pyrophosphate caused an increase in pH and a decrease in the acidity and turbidity of reconstituted milk samples. The decrease in turbidity was attributed to either dispersion or swelling of the casein micelles. The addition of mixtures containing the lowest amounts of tetrasodium pyrophosphate considerably reduced the insolubility index, whereas mixtures containing higher levels of tetrasodium pyrophosphate exerted a detrimental effect on solubility. Interestingly, microscopic observations showed large agglomerated particles in mixtures with the highest level of tetrasodium pyrophosphate. We hypothesized that the formation of casein calcium-pyrophosphate complexes led to the higher insolubility index in this mixture.
