The present invention relates to a manufacture method for simulated vegetarian sea cucumbers. The simulated vegetarian sea cucumbers mainly comprise the following ingredients: water, konjac flour, trehalose and abalone starch. White material and black material manufacturing, combined ingredient stirring, mold forming and cooking are conducted to prepare the simulated vegetarian sea cucumbers, and simulated vegetarian food with different shapes can also be prepared according to different mold forming. Konjac in the manufactured simulated vegetarian sea cucumbers can effectively absorb cholesterol and bile acids, and can inhibit intestinal absorption of the cholesterol and bile acids. The simulated vegetarian sea cucumbers have special functions of lowering lipids and blood pressure, appetite promoting, relaxing bowels, supplementing calcium, balancing salt contents, clearing stomach and intestines, dispelling toxins, preventing cancers, etc., have good chewing properties, are closely connected in internal tissues, rich in flavor, and full and lifelike in the appearance, and have appearance characteristics of true sea cucumber animals.
