Abstract

The invention discloses a fresh-keeping method of freshwater fishes. The fresh-keeping method comprises the following steps: feeding and slaughtering the freshwater fishes, blending a salting solution, salting the freshwater fishes, and freezing and storing. According to the fresh-keeping method disclosed by the invention, the freshwater fishes are fed with a saline solution before being slaughtered and the freshwater fishes are rinsed with the saline solution after being slaughtered and washed, so that fish flesh cells reach an optimal salting-in state; the fish flesh muscle cells are protected at freezing, storage and unfreezing phases, and are at a stable state all the time, so that the loss of cytochylema in the muscle cells can be reduced. Meanwhile, the fishes are salted with the salting solution prepared from pure water, table salt, white granulated sugar and I+G, so that the fish flesh muscle cells can keep moisture at the freezing, storage and unfreezing phases; especially, water loss of the fish flesh muscle cells is reduced after the fish flesh muscle cells are unfrozen, and the disadvantage that the umami is reduced, caused by freezing, storage and unfreezing steps can be made up.

Description

A kind of preservation method of fresh-water fishes
Technical field
The present invention relates to a kind of preservation method of fresh-water fishes, more particularly to a kind of natural pickling of fresh-water fishes freezes fresh-keeping Method, belongs to food storage preservation field.
Background technology
Fresh fish has good water-retaining property, Fresh & Tender in Texture, delicious flavour quality characteristic, but through the fresh of cooling freezing storage The slightly long fresh fish of fish, particularly storage time, the good water-retaining property and tenderness of fish is reduced when cooking after defrosting, especially delicious taste Road is greatly reduced.But the freezing of fish is again to have to adopt in processing of aquatic products, therefore the fresh-keeping always water of fish The technical barrier in product field.Existing freezing method, including ultralow temperature freeze, fresh chemically etc., although can be to a certain extent The freshness of fish is kept, but has that fresh-keeping effect is not good or cost is too high or there are the defects such as potential chemical contamination hidden danger, needed for this A kind of natural preservation method is invented, fresh-water fishes can be made after certain hour freezing, still can be kept substantially during culinary art Fresh fish good water-retaining property, Fresh & Tender in Texture, delicious flavour characteristic.
The content of the invention
It is an object of the invention to provide a kind of preservation method of fresh-water fishes, the preservation method can make light after freezing storage When water fish is used for cooking techniques after thawing, good water-retaining property, Fresh & Tender in Texture, delicious flavour characteristic that fresh fish has can be still kept.
To reach above-mentioned purpose, a kind of preservation method of fresh-water fishes that the present invention is provided comprises the steps:
(1) nursing of fresh-water fishes and process is butchered:The fresh-water fishes fished for are put into nursing 4~6 hours in physiological saline, so After slaughter and gill and fish scale, rinsed with physiological saline again after cleaning, it is standby after draining away the water;
(2) modulation of pickling liquid:Appropriate salt, white granulated sugar and I+G are dissolved in pure water, pickling for fresh-water fishes is obtained Liquid;
(3) fresh-water fishes are pickled:Fresh-water fishes are put into pickling liquid, are pickled in the cooling condition;
(4) freeze and cold storage:Fresh-water fishes after pickling are placed in refrigerating chamber and are suddenly frozen, taken out after fully charge and load vacuum Bag, then enters to freeze storehouse storage.
Further, the weight ratio of pure water, salt, white granulated sugar and I+G described in step (2) is 100:0.9~1.0: 1.0~1.2:1.0~1.4.
Further, carry out in the cooling condition pickling described in step (3) and refer to and pickled at 2~4 DEG C, when pickling Between be 6~8 hours.
Further, the temperature of refrigerating chamber described in step (4) is -38~-40 DEG C, freezes temperature -18~-20 DEG C in storehouse.
The present invention using before fresh-water fishes are slaughtered with physiological saline feed, and slaughter cleaning after floated with physiological saline again Wash, fish body can be made to keep a kind of normal physiological status, flesh of fish cell to reach the molten state of optimal salt, freezing thereafter, cold storage Flesh of fish myocyte makes it all the time in stable state with the protection of defrosting stage, so as to reduce the stream of muscle cell inner cell liquid Lose.On the other hand, pickling liquid of the invention is adopted to be dissolved in pure water by appropriate salt, white granulated sugar and I+G and is obtained, white granulated sugar Flesh of fish myocyte can be made freezing, cold storage and defrosting stage remain moistening, particularly reduce and oppress myocyte's after thawing Dehydration, and a certain amount of I+G can make up due to freezing, cold storage and caused by thawing delicate flavour decline, therefore fresh-keeping side of the invention When method can make fresh freshwater fish be used for cooking techniques Jing after freezing storage, still can keep good water-retaining property that fresh fish has, it is Fresh & Tender in Texture, The characteristic of delicious flavour.
