    • The present invention is directed to seamless capsules and methods for making seamless capsules having a high oil content as described herein. More specifically, the present invention is directed to seamless capsules, and methods for making seamless capsules, made from a process involving the steps of: (a) preparing an emulsion comprising oil, water, an emulsifier, and at least one of a water-soluble monovalent metal salt, polyvalent metal salt, and an acid, wherein said oil is present in an amount of at least 50% by weight of said emulsion; with the proviso that said emulsion does not contain marmelo mucilage; and (b) adding portions of said emulsion to an aqueous gelling bath comprised of at least one ionic polysaccharide thereby encapsulating said portions of said emulsion in a polysaccharide gel membrane, and optionally (c) drying the resulting capsules by removing water.Improved methods are described for preparing seamless capsules comprising oil and water emulsions containing high concentrations of oil, where the emulsions are suitable for encapsulation into capsules of a polysaccharide gel. Of particular interest are emulsions of oil and water, where the oil is present in an amount of at least 50% by weight of the emulsion and the capsule is, for example, an alginate gel. Oils that are a pharmaceutical active agent, a nutritional supplement or a food; or oils that act as a carrier therefore, are also of particular interest. According to a preferred embodiment of the present invention the emulsion may contain further solid or liquid or gaseous components and be mixed to a dispersion before the encapsulation. The capsules of the invention are suitable for a variety of applications, e.g., pharmaceutical, nutraceutical, veterinary, agricultural, cosmetic, or food applications.
    • 本发明涉及无缝胶囊和制备具有高油含量的无缝胶囊的方法,如本文所述。 更具体地说,本发明涉及无缝胶囊和制造无缝胶囊的方法,该方法包括以下步骤:(a)制备包含油,水,乳化剂和至少一种水溶性乳液的乳液, 可溶性一价金属盐,多价金属盐和酸,其中所述油以所述乳液的至少50重量%的量存在; 条件是所述乳液不含马尔默粘液; 和(b)将所述乳液的一部分加入到由至少一种离子多糖组成的水性凝胶浴中,从而将所述乳液的所述部分包封在多糖凝胶膜中,并任选地(c)通过除去水干燥所得胶囊。 描述了用于制备包含含有高浓度油的油和水乳液的无缝胶囊的改进方法,其中乳液适于包封在多糖凝胶的胶囊中。 特别令人感兴趣的是油和水的乳液,其中油以乳液的至少50重量%的量存在,并且胶囊是例如藻酸盐凝胶。 作为药物活性剂,营养补充剂或食物的油; 或作为载体的油也是特别有意义的。 根据本发明的优选实施方案,乳液可以含有另外的固体或液体或气体组分,并且在包封之前与分散体混合。 本发明的胶囊适用于各种应用,例如药物,营养,兽医,农业,化妆品或食品应用。
