It can be eaten the next day at low temperatures.

1. Collection and processing

Between August and October, jellyfish often float in groups on the sea and can be used Net fishing. After catching, the mouth and wrist are processed into "jellyfish heads".

Fresh jellyfish heads can be soaked in clean water first, change the water frequently to remove saltiness and sand, and then chop into small pieces.

Pickling jellyfish heads can be roughly divided into four steps: ① Initial alum: Place the jellyfish heads for 5 hours to allow blood to ooze out as much as possible, then add an appropriate amount of seawater at a rate of 6.5kg of alum powder per 100kg Stir to make the alum content uniform and ensure quality. ② Dialum: Take out the primary alum jellyfish heads and drain them for 1-2 hours, then add 12-14kg of salt and alum mixture [100: (2.5-3)] per 100kg to marinate. First sprinkle a little salt and alum mixture on the bottom of the bucket, and then marinate layer by layer (each layer is about 20cm thick). Put the salt and alum mixture in each layer. After marinating, add salt to the top layer. After 5-6 days, the two-alum product is ready. ③Trialum: Take out the dialum jellyfish head and drain it for 1 hour. Add 12-14kg of salt and alum mixture [100: (1-1.5)] for every 100kg and marinate. The method is the same as the dialumin process. After 6 days, the trialumite product is ready. . ④ Drying: Take out the three-alum jellyfish heads from the bucket, pile them on the clean ground with a height of 1.5m, and drain the brine for 1 week. Turn it over from top to bottom once in the middle to drain the brine quickly. Pickled products.

2. Preparation method

"Depu Materia Medica": "Bleach off the lime alum." Currently, soak the jellyfish in clean water for 2-3 days, change the water every day, and wait After blanching, remove, chop and dry.

Morphological characteristics

1. Jellyfish: Jellyfish are usually light blue to cyan blue when they are alive. The umbrella is hemispherical, with a diameter of generally 25-45cm and a maximum of about 50cm. The umbrella body is thick and the edges gradually become thinner. The surface of the outer umbrella is smooth. There are 8 notches on the edge of the umbrella, and there is 1 sensor inside each. It is located between the notches at the ends of the main spoke and the intermediate spoke. Each 1/8 of the umbrella edge has 14-20 lobes. The inner umbrella has well developed concentric ring muscles. There is a horseshoe-shaped gonad in each of the four interradials, and a small wart-like protrusion in the lower cavity. They are alternately arranged with the four oral pillars and converge toward the center to form a prismatic wrist disk, from which they extend outward. There are 8 pairs of shoulder boards with flat left and right sides, each with 40-50 filaments. There are 8 wing-shaped orifices downward from the shoulder plate. Each orifice has 150-180 filaments and 30-35 rods. There are many suction openings on the wrinkles on the edge of the arm. There are 16 radial tubes in the central gastric cavity of the inner umbrella, namely 4 main spokes, 4 intermediate spokes, and 8 secondary spokes. They are connected to each other through their inner and outer branches (only the secondary radial tubes do not branch on the inside), forming a Net-like, and all extend to the edge of the umbrella. Four radial tubes extend from the main spoke position at the bottom of the stomach cavity, each branching downwards to eight oral wrists, and branching multiple times into the suction port to communicate with the outside world. The mouth and wrist appendages are milky white or translucent, sometimes the mouth and wrist and shoulder plates are reddish brown, and the mouth is brown. Gonads yellow. However, the color of male individuals is slightly lighter than that of female individuals.

2. Yellow-spotted jellyfish: The adult body is generally milky white, with yellowish-brown spots on the surface of the outer umbrella. The diameter of the umbrella reaches 21-45cm, and the maximum is about 54cm. The center of the umbrella is thick and the edges become thinner. The surface of the outer umbrella is rough, with numerous small and pointed conical yellow-brown protrusions (this is a significant difference from the previous species). There are 8 oblong lobes every 1/8 of the umbrella edge. There is one gonad in each of the four interradials of the inner umbrella. The genital papillae in the lower cavity are large, oval, and have spike-like protrusions on the surface. There are 8 mouth and wrists, three-winged, with many short rod-like appendages, the ends of which are swollen and spherical. The wrist ends and appendages on the wrists are yellowish brown, and the mouth, wrists and gonad folds are milky white.
