Embodiment 1

[0013] 1. Overwashing: After the fresh and live sandworms have fully washed the body surface sediment, use a 10cm long blunt bamboo stick or steel needle to turn the sandworms over from the tail to the snout in a basin filled with sea water, and remove Wash the internal organs until there is no residue;

[0014] 2 Sand removal: use scissors to cut off the rostrum of the sandworm, pull apart the chordate nerve embedded in the longitudinal lines of the body wall, and use an ultrasonic cleaner ( Model KQ-250DB) Ultrasonic cleaning with pure water for 1min, during this period, stir with an electric mixer at 10rpm, the sand particles hidden in the grains and gaps of the sandworm body wall will sink to the bottom;

[0015] 3. Blanching water: Put the sandworms after desanding treatment into hot water at 70°C, blanch in water for 90 seconds, stir continuously during this period to make the heat even, remove and drain;

[0016] 4. Drying: Arrange the drained sandworms in a sand net,...

Embodiment 2

[0020] 1 Overwash: After the live sandworms have fully washed the body surface sediment, use a 15cm-long blunt bamboo stick or steel needle to turn the sandworms over from the tail to the snout in a basin filled with sea water, and remove Wash the internal organs until there is no residue;

[0021] 2 Sand removal: use scissors to cut off the rostrum of the sandworm, pull apart the chordate nerve embedded in the longitudinal lines of the body wall, and use an ultrasonic cleaner ( Model KQ-250DB) Ultrasonic cleaning with pure water for 2 minutes, stirring with an electric mixer at 10rpm during the period, the sand hidden in the grains and gaps of the sandworm body wall will sink to the bottom;

[0022] 3. Blanching water: Put the sandworms after desanding treatment into hot water at 90°C, and blanch them for 60 seconds. During this period, keep stirring to make the heat even, remove and drain;

[0023] 4. Drying: Arrange the drained sandworms in a sand net, put them in an oven...

[0027] 1. Overwashing: After the fresh and live sandworms have fully washed the surface sediment, in a basin filled with sea water, use a 20cm long blunt bamboo stick or steel needle to turn the sandworms over from the tail to the snout, and remove Wash the internal organs until there is no residue;

[0028] 2 Sand removal: use scissors to cut off the rostrum of the sandworm, pull apart the chordate nerve embedded in the longitudinal lines of the body wall, and use an ultrasonic cleaner ( Model KQ-250DB) Ultrasonic cleaning with pure water for 3 minutes, stirring with an electric mixer at 15rpm during the period, the sand hidden in the grains and gaps of the sandworm body wall will sink to the bottom;

[0029] 3. Blanching water: Put the sandworms after desanding treatment into hot water at 100°C, blanch in water for 30 seconds, stir continuously during this period to make the heat even, remove and drain;

Abstract

The invention discloses a processing method of dried sand-free sipunculus nudus. The processing method comprises following steps: step (1), turning washing: fresh and alive sipunculus nudus with sand on the body surface washed off is taken and is poked to overturn from the tail to rhynchodaeum by a blunt-end bamboo stick or steel needle which is 10-20 cm long, viscera are removed until no residues are left, and the sipunculus nudus is cleaned; step (2), sand removing: the rhynchodaeum of the sipunculus nudus in the step (1) is cut off by a pair of scissors, ventral nerve cords embedded in longitudinal lines of the body wall are pulled open, an ultrasonic cleaner performs ultrasonic cleaning for 1-3 min, an electric mixer performs mixing under 10-15 rpm during ultrasonic cleaning, and accordingly, sand grains hidden in the lines and gaps of the body wall of the sipunculus nudus are sunk to the bottom; step (3), blanching: the sipunculus nudus subjected to sand removing treatment in the step (2) is put in hot water at the temperature of 70-100 DEG C and blanched for 30-90 s, and the sipunculus nudus is continuously stirred for uniform heating during blanching and then is fished out and drained; step (4), drying: the sipunculus nudus drained in the step (3) is arranged in a mesh, put in a drying oven at the temperature of 45-55 DEG C and subjected to blast drying until the moisture content is 8.96%-11.87%. The sand content of the dried sand-free sipunculus nudus is lower than 0.1%, the taste is fine and smooth, and a sand feeling is avoided.

Description

technical field [0001] The invention relates to a processing method for sand-free sandworm dry products, and belongs to the technical field of marine product processing. Background technique [0002] Checkered Starworm (Sipunculus nudus) , commonly known as "sand worm", also known as "sand intestine worm", produced in the mud and sand of coastal beaches, is a high-protein rare seafood specialty. Domestically, it is mainly distributed in Guangdong, Guangxi, Hainan, Fujian and the coastal areas of Shandong, among which Beihai City and Zhanjiang City in the Beibu Gulf have the largest resources. The name of sand worms is ugly, but its nutrition, taste, and medical and therapeutic value are no less than other rare seafood treasures, and it has the reputation of "ocean wormwood". In recent years, with the gradual maturity of sandworm nursery and breeding techniques, the production of sandworms has increased year by year. Except for a small number of sandworms that are sold live...
