Abstract
The present invention relates to aquatic products processing technology field, and in particular to a kind of drying method of large yellow croaker.Comprise the following steps：（1）Pretreatment：The large yellow croaker thawed after fresh large yellow croaker or freezing after fishing for removes internal organ and the fish gill, and with cleaning fluid that fish body surface and internal washing is clean, quickly drains；（2）Immersion：Pretreated large yellow croaker is put into soak, aided at 30 40 DEG C so that after 15 60min of ultrasound immersion, fish body to be pulled out, it is standby,（3）Surface treatment：Formed on fish body surface using smearing or sprinkling and dry oil reservoir,（4）Dry：The 1min of rapid draing 0.5 first at 100 120 DEG C, then with 50 60 DEG C of 1 2h of drying of circulating air form, then by the flesh of fish, backlight is dried 23 days at 20 30 DEG C.This method is used to large yellow croaker processing is dried, and facilitates the preservation of large yellow croaker.This method processing time is short, retains preferable to the color and luster of large yellow croaker, and the flesh of fish will not be caused to darken in processing procedure.
Description
Technical field
The present invention relates to aquatic products processing technology field, and in particular to a kind of drying method of large yellow croaker.
Background technology
Large yellow croaker is warm warm nature coastal waters mass migration fish, is mainly inhabited in bank and the offshore waters within 80 meters
Lower floor.Usually perch compared with abysmal area, laid eggs to coastal waters migration the 4-6 months, littoral forage is dispersed in after spawning, be food with fishes and shrimps etc..
The shoal of fish that lays eggs is afraid of strong light, happiness adverse current, the good less muddy waters of transparency.Being floated when dawn, dusk or spring tide more, daytime or small
The time of tide sinks.Adult fish mainly ingests various small fishes and crustacean（Shrimp, crab, mantis shrimp class）.The reproduction peak period intensity of feeding shows
Reduction；Reproduction terminates rear intensity of feeding increase.The zooplankters such as juvenile fish staple food Copepods, oppossum shrimp, Phosphorus shrimps.Rheum officinale meat quality of fish compared with
Good and delicious, " sweet ＆ sour boneless yellow croaker " is banquet delicacies.Most of marketing fresh, other salt marsh go to wash down solarization after internal organ salt marsh into " melon dried fish "
It is drying into " dried yellow croaker " or can be made.Air bladder can be drying into rare food " fish maw ", can make again " yellow croaker glue ".Large yellow croaker liver
Containing vitamin A, for the good raw material of cod-liver oil processed.Otolith can be made medicinal.
In current rheum officinale fishery -ies product, often drop large yellow croaker and be fabricated to dried fish, it is common practice to use day illumination
The form penetrated is dried, and this mode is due to relying on artificial experience, and often quality is uneven, and big after drying
Yellow croaker color is deteriorated, and nutrition leak is serious, and the drying time is long in addition, heavy dependence weather conditions.
One application is 201510096245.3, and Publication No. 104605003A Chinese patent discloses a kind of air bladder
Drying means, fresh fish fish glue is splitted, and removes blood vessel and mucous membrane, is cleaned, with milk to be dried under reduced pressure.The consumption of milk is 100g fresh fish fish glues
Plus 100-300g milk, being dried under reduced pressure is less than 60 DEG C and is dried under reduced pressure, and it is pressure in below 2kPa to be dried under reduced pressure.
Require different because air bladder is different from the purposes oppressed, therefore to dried mouthfeel and dry mass, and be somebody's turn to do
Although air bladder can be dried for the method for patent, this method is not suitable for large yellow croaker is dried.

This method mainly pays attention to pickling for the flesh of fish, and pickling process changes the original taste of large yellow croaker.And it is processed
Overlong time, is unfavorable for scale and production.
The content of the invention
The invention aims to solve the above problems, there is provided a kind of drying method of large yellow croaker.
The drying method of the large yellow croaker of the present invention, for large yellow croaker to be dried into processing, facilitates the guarantor of large yellow croaker
Deposit.This method processing time is short, and color and luster preferably, will not cause the flesh of fish to darken.This method is simply dried the flesh of fish
Processing, does not change original taste of the flesh of fish.After this method is handled, the flavor loss of large yellow croaker is less, more protects
Original taste is stayed.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of drying method of large yellow croaker, comprises the following steps：
