Description

Fresh-preserving method for shrimp and crab food

The present invention relates to the preservation method of aquatic products such as a seed shrimp crab.

Aquatic products such as shrimp crab are the food that broad masses like, delicious flavour is nutritious.But the preservation of shrimp crab, fresh-keeping problem never is resolved.The shrimp crab mostly is freezing preservation before this, but the shrimp crab nutritive value after freezing reduces greatly, and it is bad that taste becomes.For many years, people are just gone on the market season the shrimp crab, just can buy fresh shrimp crab, and the listing phase is very short; Has only the freezing shrimp crab other seasons.

The purpose of this invention is to provide a kind of keeping fresh at normal temperature method, the aquatic products such as shrimp crab through this method is handled can keep its delicate flavour the long period at normal temperatures, and when edible, needn't handle, and can promptly tear open instant, convenient and healthy.

Preservation of fishery method provided by the invention comprises cleaning, solution impregnation, and packing vacuumizes operations such as processing, boiling sterilization processing; At the matting water dirt of aquatic products band is rinsed well; The aquatic products of wash clean are put into maceration extract, normal temperature dipping 2-6 hour; Maceration extract is the aqueous solution that contains salt and condiment, wherein contains salt 1-8%, acetate (or citric acid) 1-2.5%, and sugar 1-10%, and add a little Chinese prickly ash, condiment such as ginger; Dipping finishes, and aquatic products are pulled out from maceration extract, and in the food-packaging bag of packing into and vacuumize, seal, vacuum should be greater than 700 millimetress of mercury in the bag; Again food bag is put into steamer, boiling 20-40 minute, temperature was controlled at 100-105 ℃, is cooled to normal temperature storage at last.

Preservation method provided by the invention also can be by cleaning, packing vacuum-pumping and sealing, and operations such as boiling sterilization are carried out; Can determine the choice of impregnation process operation and the preparation of maceration extract as required.

Preservation method provided by the invention is preserved shrimp crab half a year and is not still lost delicate flavour, and can store at normal temperatures, is easy to keeping and transportation.Preservation of fishery method provided by the invention, technology is simple, processing ease, energy savings, product can promptly be torn open instant, convenient and healthy.This preservation method is widely used in the Preservation Treatment of shrimp, crab, fish, shellfish.

Embodiment 1

Get one of sea crab, scrub clean, put into the maceration extract dipping 2 hours; Maceration extract contains salt 5%, and sugar is 1%, and other is with Chinese prickly ash, ginger a little; Behind the dipping, crab is pulled out from liquid, vacuumizes vacuum 710 millimetress of mercury, envelope then in the food-packaging bag of packing into; Food bag behind the envelope was put into the steamer boiling 30 minutes, 102 ℃ of steamer temperature; Be cooled to normal temperature storage at last.

Embodiment 2

Get two of extra large shrimps, clean, put into the maceration extract dipping 4 hours; Maceration extract contains salt 8%, and other is with Chinese prickly ash, condiment such as ginger; Shrimp is pulled out from maceration extract, in the food-packaging bag of packing into and vacuumize, and vacuum 700 millimetress of mercury, envelope was put into the steamer boiling 15 minutes then; Be cooled to room temperature storage at last.
