    • The present invention relates to a method for the preparation of starch particles in a two-phase system, which method comprises at least the following steps: a) a preparation of a first phase comprising a dispersion of starch in water; b) preparation of a dispersion or emulsion of the first phase in a second liquid phase, with the proviso that the second phase is not water; c) cross-linking of the starch present in the first phase; d) separating the starch particles thus formed. According to a first aspect of the invention the second phase consists of a hydrophobic liquid and step b) consists in forming an oil-in-water emulsion, which is then inverted to a water-in-oil emulsion. According to a second aspect of the invention, the second phase consists of a water- miscible non-solvent for starch. Starch particles of very small particles size can be produced in a controlled manner by means of this method.
    • 本发明涉及一种在两相体系中制备淀粉颗粒的方法,该方法至少包括以下步骤:a)包含淀粉在水中的分散体的第一相的制备; b)在第二液相中制备第一相的分散体或乳液,条件是第二相不是水; c)第一相中存在的淀粉的交联; d)分离由此形成的淀粉颗粒。 根据本发明的第一方面,第二相由疏水性液体组成,步骤b)包括形成水包油乳液,然后将其倒入油包水乳液中。 根据本发明的第二方面,第二相由用于淀粉的水溶性非溶剂组成。 可以通过该方法以受控的方式制备非常小粒径的淀粉颗粒。
