Whey demineralization

For more than 30 years, the EDR mode has been the process of choice in the desalination industry. It is today applied in other ED applications (e.g., whey demineralization) by other companies too (http //www.ameridia.com). 

The present ED industry has experienced a steady growth rate of about 15% since 15 years (Srikanth, 2004). The most important industrial ED application is still the production of potable water from brackish water. However, other applications either in the semiconductor industry for the production of ultrapure, that is, completely deionized water without the chemical regenerations of IERs or in the food industry (i.e., whey demineralization, tartaric stabilization of wine, fruit juice deacidification, and molasses desalting) are gaining increasing importance with large-scale industrial installations.

The ash content of human milk is only about 0.2% the concentration of all principal and several minor ions is higher in bovine than in human milk (Table 5.2). Consumption of unmodified bovine milk by human babies causes increased renal load and hence demineralized bovine milk or whey should be used for infant formulae. 

The yield and purity of the crystals are affected by the protein and mineral content of the starting material the highest purity and best yields are obtained from deproteinized-demineralized whey.

Despite the first industrial ED application in the food sector dated back to 1960 and concerned the demineralization of cheese whey for use in baby foods, the history of ED is longer than that usually acknowledged (Shaposhnik and Kesore, 1997). 

Demineralization of UF whey retentate as compared to UF whey permeate is generally slowed down by salt and/or proteins that build up onto and in the membranes (Perez et al., 1994). Finally, in the case of skim milk the aim of the ED process is not only to reduce the overall ash content, but also to increase the calcium/phosphate ratio to about 0.77 in skim milk powder used in infant formula (Batchelder, 1987), this goal being much easily achievable by replacing the conventional membranes with selective ones (Andres et al., 1995).

Further reduction in cost of the chitinous supplement was achieved in two experiments with young ruminating neifers where we supplemented whey-rich rations with raw and demineralized crab meals (91.). Statistical analysis showed no significant dietary effect on net weight gain or feed efficiency for either experiment. Diarrhea increased by including whey alone in the ration. In contrast, the inclusion of either raw or demineralized crab meal alone in trie ration induced constipation. The addition of crab meal and whey to the ration restored feces to normal.
