The invention relates to a preparation method of fresh jellyfish collagens. The preparation method comprises the following steps of: selecting fresh jellyfishes as raw materials, removing antennas, cleaning and cutting into small square blocks; adding the small square blocks into an acetic acid solution, dipping and extracting for 2-3 days; filtering and collecting a filtered solution; performing electrodialysis on the filtered solution and collecting desalted liquor; making the desalted liquor flow through an ultrafiltration membrane with molecular mass of 5000-10000 Da and performing ultrafiltration, purification and concentration to obtain a concentrated solution; and freezing and drying the concentrated solution to obtain collagen powder. The fresh jellyfish collagens which are prepared by the preparation method is extracted by using an acid process to furthest keep triple-helical structures of the fresh jellyfish collagens; and according to the preparation method, electrodialysis is carried out before performing ultrafiltration to remove high valent salts and coordinates with the ultrafiltration to reduce salt content of collagen products, so purity of the products is high. Crude collagen liquor has the advantage of low electrodialysis cost and is easy to achieve industrialization.
