Abstract
The invention discloses a kind of defreezing methods of liquid nitrogen freezing flesh of fish, the preparation of the laying of preparation, cover film, the placement of the flesh of fish, defrosting environment including thawing apparatus and the defrosting processing of the flesh of fish, thaw to the liquid nitrogen freezing flesh of fish by the setting of control water flow size and thawing apparatus.Thaw the flesh of fish by the method for the invention, and cost is relatively low, and device easily prepares, and thaws minimum to the damage of the flesh of fish, and the nutritional ingredient for the guarantee flesh of fish that can be maximized, thawing time is shorter, practical value with higher.
Description
Technical field
The present invention relates to technical field of aquatic product processing more particularly to a kind of novel defreezing methods of the liquid nitrogen freezing flesh of fish.
Background technique
The aquatic products of liquid nitrogen flash freezer processing can keep higher freshness, taste and coloration, and it is thin to kill part
Bacterium reaches higher hygienic requirements.Due to preservation higher cost, it is usually used in preservation and treasures rare kind or high-value product.The flesh of fish
Food delicious as fine and tender taste, full of nutrition, very popular all over the world, especially some expensive fishes produce
Product, it is delicious in taste and full of nutrition, processed fish meat products can usually be saved by the way of liquid nitrogen flash freezer, be made with maximization degree
The flesh of fish is fresh-keeping, then needs to thaw to the flesh of fish when edible.
Currently used thawing mode has immersion method defrosting, microwave thawing, natural thaw and low temperature freezing process.Immersion method
Defrosting is that directly frozen food is put into normal-temperature water or cold water to thaw, and generally requires several hours to more than ten hour
It is able to achieve defrosting；Low temperature defrosting is thawed in the antistaling cabinet for be placed in frozen food 0-4 DEG C, since temperature is lower, one
As product be put into micro-wave oven and thaw, the time is short, but influences on food quality big.It can thus be seen that frozen food thaws
When the time required to it is longer, if user prepare cook frozen food when just thaw, can waste user's a large amount of time or
Quality comparison is big, causes user experience poor.In addition liquid nitrogen freezing quickly adds water thawing to will lead to the ice crystal breakage damage flesh of fish,
It is secondary as phenomena such as leading to myorrhexis uneven in temperature, damage the flesh of fish, it is therefore desirable to which a kind of novel thawing mode carries out water
Product thaws.
Summary of the invention
It is an object of the invention to for the shortcoming in the flesh of fish method of the above liquid nitrogen flash freezer, providing one kind can be
Do not destroy flesh of fish color, structure, under the premise of mouthfeel, the method that carries out the quick-thawing liquid nitrogen frozen flesh of fish.
In order to achieve the above object, the present invention provides a kind of defreezing methods of liquid nitrogen freezing flesh of fish, comprising the following steps:
(1) container prepares: taking a container as defrosting vessel, defrosting vessel are internally provided with temperature control device, in container
Equipped with water outlet and water inlet, by the water inlet in container to container internal water flooding；
(2) it pre-processes: a cover film being taken to be placed in vessel port top (endless totally-enclosed, there are gaps on both sides), and keep holding
Water level interface coincides with cover film lower part in device, so that liquid level is close to film；
(3) place: take the liquid nitrogen freezing flesh of fish, the flesh of fish be laid on film by single layer, keep the flesh of fish it is smooth and with covering
Film comes into full contact with；
(4) defrosting environment: container is put in sink, and there is the outlet pipe that can control flow in sink one end, can be by water flow
It is introduced on film, is secondly also equipped with multiple outlet pipes in sink two sides, control outlet pipe leather hose at a distance from the flesh of fish, and
The water flow of outlet pipe is set in advance.
(5) defreezing method: first opening the water flow of sink one end after control water temperature, control water is so that water flow infiltrates cover film
Stop water flow afterwards；Then two sides water flow is opened simultaneously, carries out flesh of fish defrosting, thawed and reach 0~4 DEG C to flesh of fish central temperature
When terminate thaw.
Preferably scheme, in step (1): container may generally be basin and other items, and upper end is opening.
Preferably scheme, in step (2): water level interface is parallel with membrane interface to coincide when being to thaw, not directly
Contact, preferably carries out heat transfer.It is endless it is totally-enclosed tap water forms interaction with water in container when being to thaw,
Lower layer's circulating water is formed, and controls temperature at 25-30 DEG C, faster completes course of defrosting.
Preferably scheme, in the step (2), cover film is made of upper layer cover film with lower layer cover film, and on
The material of layer cover film is PE or PP, and the material of lower layer's cover film is PVC, and two layers of cover film superposition is become in the present invention and is used
Cover film, defrosting vessel top is placed in, for placing the flesh of fish.
As a preferred option, in the step (2), the both sides of cover film exceed the vessel port, and the covering
Film is tilted down beyond the vessel port part, and the inclination angle with liquid level in container is 5 degree, and inclined angle can be such that part falls within
Water on cover film is more easily moved and leaves cover film；Cover film both ends exceed vessel port, and another both ends are narrower than setting for vessel port
Meter is so that there are gaps between cover film and vessel port, thus when water circulation, cover film upper part ground water energy and container
Internal water forms reflux cycle, accelerates the defrosting of the flesh of fish, and the inclination of cover film both ends can be convenient for water flowing.
Preferably scheme, in step (3): the flesh of fish being laid on film, while being that single layer is placed, is preferably guaranteed
Flesh quality.
Preferably scheme, in step (4): being greater than tap using leather hose and leather hose mouth, water can be effectively reduced
The impulse force of stream, and then flesh quality is more preferably protected, setting can preferably thaw for water flow 6-8L/ minutes, the flesh of fish after defrosting
Quality it is also more preferable.
Preferably scheme, in step (5): thawing to flesh of fish central temperature and reach 0~4 DEG C, generally can be carried out
Processing and eating.
Preferably scheme, in the step (3): water outlet is 0.5-0.6 meters apart from flesh of fish height.
The technical solution has technical effect beneficial below:
(1) defreezing method of the liquid nitrogen freezing flesh of fish of the present invention needs material simple (container uses dishware), convenient, Yi Shang
Hand, usage range are big.
(2) the less ice crystal of energy melts the damage to product for defrosting relatively conventional for liquid nitrogen freezing, and secondly product is cold
The hot uneven explosion generated, the present invention are thawed by the way of water flow, and maximization reduces the damage to flesh of fish structure, and
Nutrition loss is smaller, can preferably guarantee product quality.
(3) preferable to the Quality protection of product in the present invention, by controlling water flow 6-8L/ minutes and water outlet distance
0.5-0.8 meters of flesh of fish height, water flow should not be too large, and otherwise the impact force of water flow causes tremendous influence to flesh quality,
It is unsuitable too small, it is too low, otherwise cause thawing time too long, and then influence flesh quality.
