Jellyfish processing methods

Jellyfish, commonly known as jellyfish, stone mirror, wax, simarouba, bushy fish, jellyfish fresh and so on. So, how to further process the jellyfish after capture? The following and I specifically understand the jellyfish processing information.

Jellyfish Processing Methods

Traditional Jellyfish Processing Techniques

The traditional jellyfish processing method is to separate the jellyfish head from the jellyfish skin, and then process the jellyfish with three alums and two salts. First of all, the fresh jellyfish just caught, immediately into the porcelain tank or canvas bag, according to the fresh jellyfish body weight of 0. 2% ~ 0. 6% of the proportion of the preparation of alum, dissolved in water, marinated for 2 d, so that the fresh jellyfish astringent, discharge water, which is called / first alum 0. And then according to the body weight of the first alum jellyfish skin, add salt 12% ~ 20%, add alum 0. 5% ~ 0. 8%, and then pickled for 7 ~ 10 d, to further exclude water, which is called ? This is called "two alum and one salt". Then according to the weight of two alum jellyfish skin, add salt 20% ~ 30%, add alum 0. 2% ~ 0. 3%, and then marinate for 10 d. In this way, after 3 weeks, make the jellyfish skin moisture content down to 8% ~ 10%, that is, it will become a primary processed products. Alum is a strong dehydrating agent, the A l3+ in alum has a strong coagulation effect on protein, and the salt, in addition to the dehydrating effect, is mainly antiseptic. The reasonable proportion of the two dosages plays a decisive role in the quality indexes of jellyfish, such as color and luster, thickness, crunchiness, and product yield, etc. In general, the principle is to use the most suitable salt for the jellyfish, so as to reduce the moisture content of the jellyfish. The general principle is that the use of alum gradually from more to less, while the amount of salt gradually from less to more. It should be noted that the jellyfish must be left for a period of time, after the blood stains ooze out (i.e., rods and filaments appendages and other rotting off), and then the first alum treatment.

Common jellyfish products and processing

In addition to the traditional pickled jellyfish skin, a variety of jellyfish food has been developed in recent years.

Jellyfish soft canned jellyfish can be used as daily life of the people's small food, convenient instant food. The production process is: raw material acceptance? Soak? Rinse? Cutting silk? Rinse? Drain? Seasoning? Weigh and bag? Sealing? Sterilize and cool? Packing? Storage. Requirements: Jellyfish soaked in water for 24 h, during which the water change 2 ~ 4 times, until there is no brine flavor, and then rinse with running water.

Jellyfish powder, its process: raw material acceptance? Soak and rinse? Rough cutting? Centrifugal dehydration? Fine cutting? Drying? Packaging? Inspection? Storage. Characteristics: Fresh jellyfish of inferior grade can be used as raw material for processing; if pickled jellyfish is used, it should be repeatedly soaked and rinsed to fully remove the brine flavor. Jellyfish paste, the process is as follows: raw material acceptance? Soaking and cleaning? Crushing? Preparation? Concentration? Tanking? Venting and sealing? Sterilization and cooling? Inspection? Packing? Into the refrigerator.

Jellyfish oral liquid, the process is: raw material acceptance? Soak and rinse? Crushing? Hydrolysis? Hydrolyzed liquid refining? Filtration? Sterilization? Canning? Inspection? Finished product. The key to its technology is hydrolysis operation, can use enzyme hydrolysis, alkali hydrolysis and acid hydrolysis and other methods. In addition, the jellyfish can also be used as raw materials, the development and production of jellyfish capsules, jellyfish health wine, etc., so as to provide a variety of ways for the deep processing of jellyfish utilization.

Jellyfish toxicity principle

Jellyfish venom can cause varying degrees of damage after stinging the human body, such as the sea wasp jellyfish, stinging filaments can be secreted class Cobra venom, the most harmful to humans, stings can cause death in 5 minutes. Monkcap jellyfish contains hypnotic toxin. Hypnotoxin? This toxin is composed of peptides and proteins and small molecules containing nitrogen, and after stinging the human body, the patient will not be able to get rid of the pain for many days. There are common sand jellies floating in the Yellow Sea along the coast of China with cold currents, which can secrete peptide toxins. Jellyfish toxin in the storage and distribution of the capsule, 1 gram of the capsule contains 55 million single capsule, generally in the fishing, processing and handling of its toxicity can quickly disappear. Animal experiments have confirmed that jellyfish toxin on the mood conduction system of mammals, crustaceans have damage to the heart, and can lead to small intestine smooth muscle contraction in rodents. It is found that jellyfish toxin is tetra-ammonium complex, 5-hydroxytryptamine and peptide substances with strong histamine reaction. Its vasodilator and enhance the permeability of capillaries than 5 a hydroxytryptamine effect of 10 and 15 times, respectively, but also smooth muscle contraction, or the occurrence of hypersensitivity, resulting in severe pulmonary edema and anaphylactic shock, people were stung by jellyfish due to the size of the toxicity and the amount of toxin as well as the individual sensitivity to the degree of symptoms are different.

Symptoms of toxicity

The human skin is the most vulnerable to sting, usually in a few minutes of electric shock-like tingling sensation, a few hours after the injury area gradually electric shock-like tingling sensation, a few hours after the injury area gradually appeared in a linear arrangement of erythematous rashes, itchy and burning pain, light can be healed in about 20 days. Patients with strong sensitivity may have localized erythema, edema, wheals, blisters, petechiae, or even epidermal necrosis. The systemic manifestations of the patient may include irritability, chills, abdominal pain, diarrhea, depression and chest tightness and shortness of breath. In severe cases, coughing and wheezing episodes, spitting white or pink foamy sputum, and accompanied by signs of anaphylactic shock such as weak pulse, skin bruising and drop in blood pressure. If the rescue is not timely, this kind of sting patients can die in a short time.

Case

July 29, 1987, the wind blew a large number of stings into the Beidaihe beach bathing. The long tentacles of the jellies were like the hair of a young girl, and their round ? head? Jade-like lovely, a contraction of swimming is more elegant and moving, many bathers were confused, have to catch it with their hands, hold it. However, it is precisely in this? intimate embrace? in, more than 600 people were stung; a young woman called Li Yunfen was extremely poisoned, and died after rescue.

August 11, 2014, from Mudanjiang to Dalian tour of men and friends to the Xinghai Bay bath. In the sea heard the call for help, swim over and found a girl, there is a big jellyfish beside him, there is a tent open so big, he bravely pushed away from the jellyfish, but he was stung. Later that night, the man passed away without rescue.

Sting statistics

China's vast sea area, every year in July and September there are a considerable number of jellyfish sting cases, before the main fishermen fishing jellyfish, swimming in the waterfront play water stings patients. For example, Qinhuangdao seashore has been stung by more than 3,400 patients in recent years. According to the tourist resort Beidaihe seaside hospital statistics, since 1989 5 years, **** admitted to be stung patients 3030 cases, which caused sudden anaphylactic pulmonary edema accounted for 0.3%, there are 4 cases of death (all accompanied by severe shock).

Prevention of stings

The most important thing to prevent jellyfish stings is to avoid contact with jellyfish, especially the operation of the fishermen to do a good job of personal protection, do not be paralyzed. When fishing, try to use tools without direct contact with jellyfish whiskers, there is a specific sensitivity of the body should be prohibited to work in the sea. During the jellyfish season, buoys should be set up in tourist spots along the seashore, and warning signs should be set up along the seashore to publicize the situation. In addition, publicity broadcasts should be made to enhance the knowledge and ability of tourists in self-protection. If swimmers or boaters find jellyfish in the sea, they must not touch them, not to mention fishing, because once an accident occurs in the sea, it is not easy to rescue them. Once stung by jellyfish, the injured must not panic, as long as the timely hospital treatment, generally can be faster and healed. On the contrary, if the stings are improper initiatives or careless paralysis, it is easy to drowning, bruises or due to untimely treatment and the danger and aggravation of the condition.
