Description
(1) technical field:
The invention belongs to technical field of aquatic product processing, are related to the quality holding conditioning of a kind of flesh of fish color and musculature
Processing method belongs to field of food.
(2) technical background
China is world fisheries big country, and fishery resources are abundant, and annual output occupies the first in the world for years.
Flesh of fish fine and tender taste, delicious flavour is full of nutrition, but fishy smell or bilgy odour are heavier;In addition, due to endogenous in the flesh of fish
Property enzyme and microorganism effect, fish process transporting procedures in flavor deterioration and it is putrid and deteriorated be difficult to control, to influence it
The development of processing industry.
Conditioning food (Prepared foods) is also referred to as to be with agricultural production, livestock and poultry and aquatic products etc. for convenience of prepared food
Primary raw material, after industrialization pre-treatment and configuration processing, the food of packing and selling.The feature of conditioning food maximum is to sell
By the simple cooking, it can be served, convenient and quick.In recent years, the preconditioned food consumption amount in China grows continuously and fast, because
This, research and development deliciousness, safety and the high-quality flesh of fish of nutrition conditioning product have boundless market prospects.
(3) summary of the invention
The purpose of the present invention is to provide a kind of qualities of flesh of fish to keep cooking processing method, and fish body is added by pretreatment
Work, using quick freezing, the flesh of fish conditioning product after can making freezing storage has the muscle texture quality of fresh fish.
In order to achieve the above objectives, the quality that the present invention provides a kind of flesh of fish keeps cooking processing method, specific as follows:
(1) live fish pre-processes
Live fish after capture first rests 2~48 hours in 20-25 DEG C of water, and then live fish is transferred in ecological ice-temperature water,
The water temperature of the ecological ice-temperature water is -2 DEG C~1 DEG C (preferably -2 DEG C~0 DEG C), meanwhile, it is passed through CO in water, rests 1~24 small
When;
The live fish includes freshwater fish and seawater fish, and including but not limited to silver carp, bighead, Tilapia mossambica, grass carp etc. is light
The fishs such as water fish and cultivation yellow croaker, orange rock-fiss;
In the present invention, live fish is put into ecological ice-temperature water, can coerce flesh of fish muscle fibril and generate cold stress and shrink makes
Muscle fibre density improves, and is passed through CO in water, is to form carbonyl myoglobin using the effect of CO and living body flesh of fish myoglobins,
To reach color development purpose.
Further, when being passed through CO, final concentration of 0.001~20ppm of CO in ecological ice-temperature water, preferably 0.02~
0.25ppm;
Further, the mass ratio of live fish and ecological ice-temperature water is 1:2~10.
By this step, fish body muscle fibre can be allowed to generate cold events phenomenon, the muscle segment of muscle fibril is by unfolding state
2.10~2.30 μm become 1.80~2.10 μm of contracted state
(2) fish body pre-treatment
The fish that step (1) is handled well blood of scaling is removed into internal organ, is cleaned, is drained, be cut into the required flesh of fish;
The flesh of fish type includes but are not limited to fillet, fish section, full fish, fish head, fin etc..
Fillet general thickness is 5~30cm having a size of 3~4mm, the general length dimension of fish section;
(3) the pulsed breathing tumbling of the flesh of fish and the clothing that covers on flesh of fish surface consolidate film
The flesh of fish that step (2) is handled well is transferred to vacuum tumbler, tumbling liquid is added, vacuumizes carry out knead-salting, institute
Stating knead-salting is to carry out pulsed breathing to pickle, program are as follows: vacuumize tumbling 0.5~1 hour, make micro in flesh of fish myocyte
The expansion of gas decompression, then open valve Rapid degassing makes the gas of expansion restore reset condition to normal pressure, then vacuumizes tumbling
0.5~1 hour, opening valve Rapid degassing to normal pressure, thus circulation repeatedly carries out breathing marinated, then discharges, drains;
