A process is provided for treating a solution, gel, or suspension of pectin starting material having a degree of esterification greater than about 60% with a cation-containing preparation to obtain at least a first fraction having a higher degree of calcium sensitivity and a second fraction having a lower degree of calcium sensitivity than said pectin starting material. The resultant composition has a degree of esterification greater than about 60% and a ratio of calcium sensitive pectin to the sum of calcium sensitive pectin and non-calcium sensitive pectin greater than about 0.60. Compositions using citrus pectin have a degree of esterification less than about 80% and a ratio on non-calcium sensitive pectin to the sum of calcium sensitive pectin and non-calcium sensitive pectin greater than about 0.60. These compositions are used, for example, in admixture with foodstuffs, in personal hygienic devices, and in cosmetics.
A process comprising treating a solution, gel or suspension of pectin starting material having a degree of esterification greater than about 60% with a cation-containing preparation to obtain at least a first fraction having a higher degree of calcium sensitivity and a second fraction having a lower degree of calcium sensitivity than said pectin starting material wherein the cation-containing preparation comprises a cation that is a metal ion derived from salts selected from the group consisting of alkaline earth metal salts, alkali metal salts, transition metal salts, and mixtures thereof.
