Fractionated agaroid compositions, their preparation, and use |
摘要 |
A process for fractionating agaroid compositions by dissolving the agaroid in a glycol, precipitating a first fraction by cooling and precipitating a second fraction by incorporating a nonsolvent to form two fractions substantially more soluble in water than the initial agaroid. Optionally the solubility of either fraction can be converted to conventional solubilities.
