[Distribution of nitrate- and nitrite-ions in a two-phase system of water-fat-free milk--anionic carboxyl containing polysaccharide].
The distribution of nitrate and nitrite ions between the equilibrium phases in the two-phase water--fat-free milk proteins--polysaccharide system has been studied. The partition coefficient was independent of the structure of the polysaccharide used (pectin, sodium salt of carboxymethylcellulose), its concentration, ionic strength of the solution and temperature, and was equal to 1.20 +/- 0.05. This can be explained by the absence of interactions between nitrate and nitrite ions and bipolymeric components of the system. The deviation of the Kd value from unit may be due to the different proportion of the solvent, water in the phases. The partition coefficient calculated with regard to this proportion was close to unit (1.06 +/- 0.05).
