Abstract: The present disclosure belongs to the technical field of soft capsules, and particularly relates to a plant soft capsule and a preparation method and application thereof. The plant soft capsule with excellent performance is prepared from carrageenan, starch, a plasticizer and water by controlling the weight-average molecular weight of the carrageenan to be 1.2×106 to 2.0×106. Compared with a plant soft capsule in the existing technology, the plant soft capsule of the present discourse has lower production cost, and the product quality meets the requirements of gelatin soft capsules; and on the premise of high production efficiency, a low oil leakage rate is achieved, and the rupture time meets United States Pharmacopoeia (USP) standards. The plant soft capsule prepared according to the present disclosure can be filled with an active component as a content and used for preparation of a plurality of drugs, functional food or dietary nutritional supplements.
