In addition, the composition can be easily formulated, and thus can be used in various dosage forms at a high content even without using a specific other ingredient to formulate the effective ingredient.

The invention discloses a lipid liquid crystal and application of the lipid liquid crystal in controlled release of anthocyanin. The lipid liquid crystal is prepared from an oil phase, anthocyanin and water, wherein the oil phase is prepared from glyceryl monolinoleate, glyceryl monooleate, mannosylerythritol lipid and linoleic acid; wherein the oil phase part contains the following components in percentage by mass: 1.0-3.6% of linoleic acid and the balance of a mixture of glyceryl monolinoleate, glyceryl monooleate and mannosylerythritol lipid, and the mass ratio of the glyceryl monolinoleate to the glyceryl monooleate to the mannosylerythritol lipid is 8.5: 1: 0.5; 25-40% of an aqueous solution containing anthocyanin; the change of the crystal form structure of the lipid liquid crystal is induced by adjusting the pH condition to control the release rate difference of the anthocyanin, so that the controlled release is realized. The lipid liquid crystals of the present invention are particularly suited for shipping and targeted delivery of anthocyanins.
