The invention provides compound mature vinegar micro-capsules as well as a preparation method and an application thereof. The compound mature vinegar micro-capsules comprise the following two parts: capsule cores and capsule walls; the capsule cores are prepared from the following raw materials: concentrated mature vinegar, a Chinese magnoliavine fruit extract, a astragalus root extract and a liquorice root extract; and the micro-capsules are prepared by the following steps: embedding the capsule cores in the capsule walls, and carrying out spray-drying. The antioxidant components of the concentrated mature vinegar and the traditional Chinese medicine extracts synergistically react, so that the micro-capsules have stronger free radical scavenging activities and better liver-protecting and health-caring functions. The micro-capsule technology is utilized, so that the antioxidant components therein are better protected so as to prevent oxidation and enhance stability; the micro-encapsulation ensures better dispersibility and sustained release of the active ingredients, so that the active ingredients can effectively and lastingly enter the sites of action to play the liver-protecting and health-caring roles; moreover, the micro-encapsulation shields strong smells of the edible vinegar and the traditional Chinese medicines, so that the color, the luster and the taste of the final products are improved.
