Estimating the term…
Mineral-containing polymeric compositions of matter having high aqueous dispersibility, and methods of synthesizing the same, are disclosed which permit nutritionally important elements such as calcium, magnesium, phosphorus, potassium, iron and certain trace elements to be added in aqueous form to foods of all types without adversely affecting taste qualities. The compositions generally are high molecular weight species having moieties of the generalized formula ##STR1## wherein M.sub.1 and M.sub.2 are polyvalent metals, A.sub.1 and A.sub.2 are respectively taken from the group consisting of hydrogen, ammonium and the alkali metals, and X is an organic acid moiety having at least three carboxyl groups therein (preferably citrate). The synthesis preferably includes the steps of admixing in water a metal cation source, a potassium phosphate source and an organic acid, followed by heating and further agitation. Dispersibility of the compositions is enhanced by the use of adjuncts such as hydroxyl sources (e.g., sugars, starches or the like), or amino acids, whey, and caseinates. Edible forms of the compositions hereof find particular utility as nutritional fortificants in traditional or ersatz foods, either for human or animal consumption; in addition, the compositions may be very useful in fertigation or foliar plant nutrition programs where minerals are applied to the soil and/or emergent plants. Nonedible forms can be useful in virtually any context wherein dispersibility is desirable.
A composition of matter which includes a moiety of the generalized formula ##STR6## wherein M.sub.1 and M.sub.2 are polyvalent and respectively taken from the group consisting of arsenic, silver, aluminum, barium, bismuth, mercury, lead, antimony, tin, beryllium, cadmium, cobalt, chromium, selenium, silicon, strontium, titanium and vanadium,
A water dispersible composition of matter which is a polymer or quasi-polymer having a molecular weight exceeding 300,000 and includes a moiety of the generalized formula ##STR8## wherein M.sub.1 and M.sub.2 are polyvalent and respectively taken from the group consisting of arsenic, silver, aluminum, barium, bismuth, mercury, lead, antimony, tin, beryllium, cadmium, cobalt, chromium, selenium, silicon, strontium, titanium and vanadium, and
