Santamaría etal. (1975) investigated the coacervation phenomenon between gelatin and potassium arabinate. It was found that the yield of the coacérvate was greatest at pH 3.5-4.1 and when potassium arabinate was in excess compared with gelatin. The coacervation decreased in the presence of potassium halide and the effect depended mainly upon the salt concentration and also on the ionic radius of the anion. Theoretical and mathematical considerations were used to interpret the phenomenon.
