Abstract
The invention discloses a kind of processing method for freezing and taking the lead Penaeus Vannmei, it is realized by following scheme：Shrimp sudden death living, cleaning and sterilizing soaks fresh-keeping, freezes water or ice and plating water glaze containing bio-preservative in plating water glaze, immersion preservation process and contains 0.3 0.5g/L nisins with water（nisin）, 0.5 1.0g/L chitosans, 35 g/L ε polylysines (ε PL), the hexyl resorcins of 0.005 0.01g/L 4（4‑HR）, 0.5 1.0 g/L L ascorbic acid（Vc）.Of the invention to suppress shrimp head polyphenol oxidase activity and microbial reproduction by low temperature control and compound bio preservation technology, solution freezing takes the lead Penaeus Vannmei course of defrosting shrimp head and easily blackhead red head phenomenon occurs, improves quality and outward appearance that prawn is taken the lead in freezing.
Description
Technical field
It is specially a kind of to freeze the processing method for taking the lead Penaeus Vannmei the present invention relates to preservation of fishery technology.
Background technology
Penaeus Vannmei is a kind of higher aquatic products of nutritive value, but Penaeus Vannmei is easily corrupt, is difficult storage
Hide, generally require chilling treatment, and use after traditional cold-storage and fresh-keeping method processing, course of defrosting Prawn head easily occur blacking,
Red change phenomenon, red change blacking greatly reduces the quality and appearance of South America prawn, has a strong impact on the sale of freezing prawn
Value.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of processing method for freezing and taking the lead Penaeus Vannmei, for solving to lead to
Cross the prawn of conventional method cold storage, the problem of blacking and red change easily occur for defrosting occiput.
In order to solve the above technical problems, the processing method that Penaeus Vannmei is taken the lead in a kind of freezing that the present invention is provided, passes through
Following scheme is realized：
A, shrimp sudden death living：Fresh and alive Penaeus Vannmei is put into the frozen water that water temperature is 0-2 DEG C, while logical CO2Gas is sudden
Extremely；
B, cleaning and sterilizing：Cleaning removes silt, weeds, and prawn then is transferred into ozone concentration for 0.8-1.0ppm, water
Temperature is soaking disinfection 3-5min in 0-5 DEG C of Ozone Water.
C, soaks fresh-keeping：Prawn after cleaning and sterilizing is pulled out and is put into heat-preserving container, one layer of shrimp, one layer of ice, then pour into containing life
10-15min is soaked in the frozen water of thing antistaling agent；
D, freezes plating water glaze：By soak it is fresh-keeping after prawn pull draining 3min out, carried out below -350 DEG C quick-frozen, make shrimp
Body core temperature is down to less than -180 DEG C, immediately after disk stripping plating water glaze, that is, obtains freezing and take the lead Penaeus Vannmei product.
Further, streptococcus lactis containing 0.3-0.5g/L in above-mentioned water or ice and plating water glaze water containing bio-preservative
Element（nisin）, 0.5-1.0g/L chitosans, 3-5 g/L epsilon-polylysines (ε-PL), 0.005-0.01g/L 4- hexylresorcinols two
Phenol（4-HR）, 0.5-1.0 g/L L-AAs（Vc）.
Further, above-mentioned cleaning water temperature is 0-2 DEG C.
The present invention suppresses shrimp head polyphenol oxidase activity by low temperature control and compound bio preservation technology and microorganism is numerous
Grow, solve freezing and take the lead Penaeus Vannmei course of defrosting shrimp head easily blackhead red head phenomenon occur, improve the quality of prawn with
Outward appearance.
Brief description of the drawings
Fig. 1 is step flow chart of the invention.
Fig. 2 is comparative experimental data figure of the invention.
Embodiment
Many details are elaborated in the following description to fully understand the present invention.But the present invention can be with
Much it is different from other manner described here to implement, those skilled in the art can be in the situation without prejudice to intension of the present invention
Under do similar popularization, therefore the present invention is not limited by following public specific embodiment.
With reference to the accompanying drawings and examples, the embodiment to the present invention is described further.
Embodiment 1
In the present embodiment, with reference to accompanying drawing, the present invention will be described in detail.The present invention passes through low temperature control and compound life
Thing preservation technology suppresses shrimp head polyphenol oxidase activity and microbial reproduction, solves freezing and takes the lead Penaeus Vannmei course of defrosting shrimp
Easily there is reddish tone blackhead phenomenon in head, improves the quality and outward appearance of freezing prawn.
The processing method that Penaeus Vannmei is taken the lead in a kind of freezing that the present invention is provided, is realized by following scheme：
A, fresh and alive Penaeus Vannmei is put into the frozen water that water temperature is 0-2 DEG C, while logical CO2Gas is died suddenly.
B, cleaning and sterilizing：Cleaning removes silt, weeds, and prawn then is transferred into ozone concentration for 0.8-1.0ppm, water
Temperature is soaking disinfection 3-5min in 0-5 DEG C of Ozone Water.
C, soaks fresh-keeping：Prawn after cleaning and sterilizing is pulled out and is put into heat-preserving container, one layer of shrimp, one layer of ice, then pour into containing life
10-15min is soaked in the frozen water of thing antistaling agent.
D, freezes plating water glaze：By soak it is fresh-keeping after prawn pull draining 3min out, carried out below -350 DEG C quick-frozen, make shrimp
Body core temperature is down to less than -180 DEG C, immediately after disk stripping plating water glaze, that is, obtains freezing and take the lead Penaeus Vannmei product.
As the preferred embodiment of the present invention, 0.3- is contained in water or ice and plating water glaze water containing bio-preservative
0.5g/L nisins（nisin）, 0.5-1.0g/L chitosans, 3-5 g/L epsilon-polylysines (ε-PL), 0.005-
