Abstract

The invention discloses a freezing processing method of golden pomfret slices, which comprises the following steps of S1: removing fishy smell material, adding water into fructus Citri Limoniae and rhizoma Zingiberis recens, squeezing to obtain juice, and adding cooking wine, vinegar, crystal sugar and salt; s2: pretreating golden pomfret, removing scales and viscera of golden pomfret, washing with water, sequentially soaking in fishy smell removing material and ethanol, taking out after soaking, and sucking ethanol and water on the surface and inside of golden pomfret with gauze; s3: pre-freezing, namely cutting the treated golden pomfret into slices, and placing the slices in a refrigerator for gradient pre-freezing; s4: and (4) freezing, namely performing vacuum freeze drying on the golden pomfret slices pre-frozen in the step S3, and freezing again to finish the freezing processing operation of the golden pomfret slices. The processing method provided by the invention is short in time consumption, and the golden pomfret slices are subjected to fishy smell removal and sterilization in the processing process, and then subjected to gradient pre-freezing, drying and freezing processes, so that the golden pomfret slices are small in nutrition loss, fresh and tender in taste and free of fishy smell.

Description

A kind of frozen processing method of golden pompano piece
Technical field
The present invention relates to aquatic products preparing technical field, more particularly to a kind of frozen processing method of golden pompano piece.
Background technology
The avette Chang Ajigasawa of golden pomfret scientific name, the yellow cured silvery pomfret of local title, golden silvery pomfret.Golden pomfret is nutritious, and protein content is higher, And containing abundant unrighted acid, there is the effect of reducing cholesterol.Golden pomfret contains abundant trace elements of selenium simultaneously And magnesium, there is prevention effect to angiocardiopathies such as coronary sclerosis, and body aging can be delayed, there is the effect of anti-cancer.Its Meat is snow-white, delicate, tasty, has very high nutritive value, especially with wild golden pomfret, is even more pursued by a person sponging on an aristocrat.
The main marketing method of golden pomfret is divided into two kinds, i.e., chilled and fresh aquatic food, because eating habit, cost of transportation and risk are asked Topic, fresh and alive golden pomfret mainly consumes in south, and northern market is then in the majority with chilled golden pomfret.Entering for chilled golden pomfret Row prepare during most critical the step of be exactly freeze cutting process.And existing freeze cutting process is generally to golden pomfret meat The damage of matter is larger, makes that the quality of the golden pomfret after freezing is relatively low, and mouthfeel is harder, and fishy smell is heavier, directly affects golden pomfret Sale and production.In addition, existing Refrigeration Technique, it is necessary to cooling time it is universal longer.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of freezing of the golden pomfret piece proposed Processing method.
A kind of frozen processing method of golden pompano piece, comprises the following steps:
S1:Prepared by deodorization material, lemon and ginger are removed the peel, and adds water to squeeze the juice, and adds cooking wine, vinegar, rock sugar and salt, mixes Uniformly produce deodorization material;
S2:The pretreatment of golden pomfret, golden pomfret is scaled, removes internal organ, and rinsed 2~5 times with water, then water is dripped to not dripping, And be immersed in the golden pomfret after washing in the deodorization material prepared in S1 steps, and with soaking 10~20min at 0~5 DEG C, take Go out, drip water to not dripping, then golden pomfret is immersed in 3~5min in ethanol solution, take out, and with gauze by golden pomfret surface And internal ethanol and moisture blot, the golden pomfret after processing is produced;
S3:Precooling, the golden pomfret after processing is cut into slices, be placed in carrying out gradient precooling, gradient precooling journey in refrigerator Sequence is:5min, temperature are down to 10 DEG C, and 10min, temperature are down to 0 DEG C, and 20min, temperature are down to -10 DEG C, 40min, temperature Degree is down to -20 DEG C, and 70min, temperature are kept for -20 DEG C, that is, completes the precooling of golden pomfret piece;
S4:Freezing, the golden pomfret piece after precooling in S3 steps is first subjected to vacuum freeze drying, then at -30~-50 DEG C of freezings 1~3h, that is, complete the freeze cutting operation of golden pomfret piece.
Preferably, the quality of lemon is the 0.5%~1.5% of the quality of water after being removed the peel in the deodorization material, raw after peeling The quality of ginger is the 3%~6% of the quality of water.
Preferably, the weight part ratio of the cooking wine, vinegar, rock sugar, salt and water is:6~12 parts of cooking wine, 1~3 part of vinegar, ice 2~6 parts of sugar, 0.5~1.5 part of salt, 90~110 parts of water.
Preferably, the weight part ratio of the cooking wine, vinegar, rock sugar, salt and water is:10 parts of cooking wine, 2 parts of vinegar, 4 parts of rock sugar, 1 part of salt, 100 parts of water.
Preferably, the mass ratio of golden pomfret and deodorization material is 1 in the S2 steps:4~6.
Preferably, the vacuum of the vacuum freeze drying in the S4 steps is 10~20Pa, and drying time is 4~8h.
Processing method proposed by the present invention, it is time-consuming short, first golden pomfret is handled in process, by golden pomfret Fishy smell remove, while fresh and alive golden pomfret is sterilized, the mouthfeel of golden pomfret after freeze cutting is effectively improved, in processing procedure It is middle to play the effect of effective deodorization using the lemon of rational proportion, ginger, cooking wine, vinegar, rock sugar and salt, and salt Addition can tentatively be sterilized to golden pomfret, then coordinate follow-up ethanol to clean, and can significantly improve sterilizing function, and eat The addition of salt can also improve the mouthfeel of golden pomfret, it is eaten mouthfeel fresh and tender, first to golden pomfret piece before refrigeration operation Precooling is carried out, and precooling program is by the way of gradient cooling, it is possible to reduce snap frozen is to golden pomfret piece meat Influence, make the nutrition leak in golden pomfret piece small, and precooling processing can also accelerate the follow-up drying of golden pomfret piece and cold Freeze speed, shorten the freeze cutting time, improve golden pomfret piece production efficiency.
