Description
Technical field
The present invention relates to a kind of live keeping agents, more particularly, to a kind of anhydrous low temperature keep-alive live keeping agent of sea crabbing and its preparation
Method, application.
Background technology
Extra large crabbing, such as swimming crab, mud crab, Sea crab etc., it is full of nutrition due to unique flavor, it is deep by consumer's
It welcomes, the huge market demand.But extra large crabbing after capture due to environmental change, the time-to-live is short, easily dead rotten, mouthfeel
It is deteriorated with flavor, it is edible to be substantially reduced with economic value.Therefore, extend food of the time-to-live for the extra large crabbing of raising of extra large crabbing
It is of great significance with economic value.
The traditional keepalive method of extra large crabbing be it is on the rocks in babinet water cool down, and be uninterruptedly oxygenated, grasp in this way
Make the keep-alive time of extra large crabbing usually at 12 ~ 24 hours, but this method is extremely onerous, but also be cannot to extra large crabbing into
Row long-time and long-distance transportation.
Anhydrous low temperature keep-alive is a kind of current extra large crabbing keepalive method of hot topic, relative to traditional keepalive method, sea
The time-to-live of crabbing is longer, and extra large crabbing long range, long-time On Transportaion of Live, cost can be realized in the form of anhydrous packaging
It is low, but in entire storing and sales process of the extra large crabbing after fishing to launch, due to the change of living environment and condition
Change, or often have partially or completely death, to cause economic loss, therefore the actual effect of anhydrous low temperature keep-alive is simultaneously
It is undesirable.
The Chinese patent of Authorization Notice No. CN102084836B, authorized announcement date 2012.12.19 disclose a kind of three wart shuttles
Sub- crab specifically discloses from water preserving active method：The sequence of operations such as low-temperature treatment, packaging, the transport of swimming crab can make shuttle
Sub- crab is in height stress situation, so that its metabolism is in excited state, is stablized using addition in the seawater in method of the invention
Type vitamin C swimming crab can be made to be in narcosis and meanwhile can be effectively relieved its stress, improve survival rate.Its shortcoming exists
In：Using vitamin C as the live keeping agent of swimming crab, the stress reaction of crab body can only be alleviated, effect is single, when crab picks up from water
Between being packed, crab hypoxia death is easily caused, in addition, there is no bacteriostasis for vitamin C, in preserving process, microorganism
Easily mass propagation is to reduce the survival rate of crab.
Invention content
The present invention is to act on single, the problem of practical keep-alive effect difference to solve the extra large crabbing live keeping agent of the prior art,
Provide it is a kind of formula is scientific and reasonable, it is at low cost, the extra large crabbing time-to-live can be greatly prolonged and improve the extra large crabbing of survival rate without
Water low temperature keep-alive live keeping agent.
The invention also discloses a kind of preparation methods of the anhydrous low temperature keep-alive live keeping agent of extra large crabbing, and processing step is simple,
Operability is strong, low for equipment requirements, small investment, is suitble to industrialized production.
To achieve the goals above, the present invention uses following technical scheme：
A kind of anhydrous low temperature keep-alive live keeping agent of sea crabbing, consists of the following mass percentage components：5 ~ 10% sulfuric acid
Magnesium, 1.5 ~ 3.5% potassium chloride, 2.5 ~ 6.5% gypsum, 7.5 ~ 15% Rosmarinic acids, 0.0025 ~ 0.0065% aldosterone, surplus are water.
Inventor, by analyzing problem of the existing technology, creatively devises a kind of full on the basis of the live keeping agent of the prior art
The anhydrous low temperature keep-alive live keeping agent of new extra large crabbing, in live keeping agent of the invention, magnesium sulfate is used to promote crab body to arrange in temporary support
Go out excreta；Potassium chloride is for maintaining crab body intracellular osmotic pressure and acid-base balance, to extend the time-to-live；Gypsum is in certain journey
It can inhibit neural stress reaction on degree, vasopermeability reduced, to inhibit the activity of crab；Rosmarinic acid can be adjusted in crab body
The activity of various metabolic enzymes reduces oxygen demand, increases the activity of antioxidase, to lacking when picking up packaging to improve crab from water
The adaptability of oxygen stimulation, improves survival rate；Aldosterone can inhibit the metabolism of crab body, improve adaptation of the crab to external environment
Ability helps to extend the time-to-live.Formula is scientific and reasonable for live keeping agent in the present invention, is matched by the collaboration between each component
It closes, the time-to-live of extra large crabbing can be extended, and improve the survival rate of extra large crabbing, be conducive to the economic valence for further increasing extra large crabbing
Value.
A kind of preparation method of the anhydrous low temperature keep-alive live keeping agent of sea crabbing, the specific steps are：It is weighed respectively by said ratio
After component, stirred evenly after magnesium sulfate, potassium chloride, gypsum, Rosmarinic acid, aldosterone are mixed with water.Each component is straight
The live keeping agent that mixing can be obtained the present invention is connect, processing step is simple, and operability is strong, low for equipment requirements, small investment, is suitble to
Industrialized production.
A kind of application of the sea anhydrous low temperature keep-alive live keeping agent of crabbing in the anhydrous low temperature keep-alive of extra large crabbing live body.Specifically
Application method is：Extra large crabbing is placed in seawater before anesthesia by freezing when being stored up or temporarily being supported, is added the present invention's in the seawater
Live keeping agent, the additive amount of live keeping agent are the 3 ~ 4% of seawer quality, extra large crabbing are then carried out anesthesia by freezing, low temperature packaging is protected
It deposits.
Therefore, the present invention has the advantages that：
（1）By analyzing problem of the existing technology on the basis of the live keeping agent of the prior art, creatively devise
A kind of completely new anhydrous low temperature keep-alive live keeping agent of extra large crabbing, formula is scientific and reasonable, at low cost, passes through the collaboration between each component
Cooperation, can extend the time-to-live of extra large crabbing, and improve the survival rate of extra large crabbing, be conducive to the economy for further increasing extra large crabbing
Value；
（2）Each component is directly mixed to the live keeping agent that can be obtained the present invention, processing step is simple, and operability is strong, right
Equipment requirement is low, small investment, is suitble to industrialized production.
