Abstract
The invention discloses a kind of dead fish block deodorization processing methods, including pre-process, deploy deodorization liquid, miniflow impregnates, adjusts pH, is flushings, air-dried and etc..The present invention can effectively with the substance for generating fishy smell or react or combine or be allowed to lose activity or directly remove or odour masking；To achieve the purpose that smelling removal.
Description
Technical field
The present invention relates to a kind of dead fish block deodorization processing methods, belong to food processing technology field.
Background technique
The flesh of fish is the good source of good protein, vitamin and mineral, and full of nutrition, delicate mouthfeel bullet is soft, especially
It is suitble to old man and children, there are many healthcare functions to human body.Counted according to FAO, 75% or more of world's total aquatic product production be by
It is sold after processing, marketing fresh ratio accounts for total output less than 25%.Since raw material fishing gear has a fish like smell this difference and other meats
Particularity, deodorization just become a key technology in fish product processing, and the purpose is to be elimination fishlike smell to greatest extent to fish system
The influence of product quality.
Fishlike smell refers to trimethylamine oxide, δ-aminovaleric acid, hexahydropyridine class, aldehydes, ketone or the fat that fish contain
The special odor that the ingredients such as acids generate, caused by the metabolism and corruption and breeding environment as fish meat protein.Belong to and compares
Complicated Combination smell, this bad smell are that multiple compounds mix showed smell.In the prior art for
The processing technique of fishlike smell develops to the green day of natural products from physico-chemical process such as initial embedding, absorption, acid-alkali salts
Right deodorization method, biological method of microbial fermentation etc., and due to fishlike smell complicated component, the fishlike smell of variety classes raw material fish
Object is closed also to have any different, therefore, single deodorization method effect has limitation, if acid-alkali salt method is specifically to be carried out using the method impregnated,
It is, in opposing stationary state, to carry out by Premeabilisation of cells principle in soak with to deodorant object that it, which is impregnated, and deodorization is uneven,
Deodorization effect is to be improved under same soaking time.In addition, for dead fish fishy smell in contrast, it is more difficult than the fishy smell of live fish
With removal.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of more reasonable dead of technological design
Fish block deodorization processing method.
To achieve the above object, the technical solution adopted by the present invention is that: dead fish block deodorization processing method, including walk as follows
It is rapid:
(1) it pre-processes: collecting still edible dead fish, concentration goes scale, decaptitating, removes internal organ, and then stripping and slicing is spare；
(2) deploy deodorization liquid: modulation deodorization liquid, by basyleave: the coptis: peppermint: clear water is 3-5:8-10:15-20:80-100's
It is cooling after weight ratio infusion 1-3h, 0.5-0.8 times of rice washing water is added, stirring evenly and salt modulation salinity is added is 1%；
(3) miniflow impregnates: impregnating 4-6h for being sent into special soaking device by the fish block of step (1) processing, soaking device
In be previously implanted the prepared deodorization liquid of step (2), make the liquid in soaking device with temperature 32-35 in soaking process
DEG C, circulated in speed 0.1-0.5m/s, and manually oxygenation makes the oxygen in water body up to saturation；
(4) it adjusts pH: after miniflow impregnates, quick lime is added in the deodorization liquid into soaking device, stirs evenly, quick lime
Additional amount is so as to adjust the pH to 12-14 of deodorization liquid, then impregnate 2-3h；
(5) it rinses, air-dry: 5-8min will be rinsed by the fish block cold boiling water of step (4) processing, and then air-dried.
Preferably, above-mentioned special soaking device includes impregnating cylinder, is fixed with hollow shaft, hollow shaft impregnating center in cylinder
Upper to be fixed with multiple fish block cleat assemblies by swivel bearing, each fish block cleat assembly is adapted by box-like bottom and with box-like bottom
The folder lid of cooperation is constituted, the one end Jia Gai and box-like bottom one end it is hinged, both other end snapping, wherein bottom offers in box-like bottom
Multiple tracks sliding slot, box-like bottom and folder lid are reticular structure and are respectively and fixedly provided with the matched filter of size on the inside of box-like bottom and folder lid
The hollow part of net, hollow shaft is connected with the space between fish block cleat assembly, and the box-like bottom in fish block cleat assembly is to incline
Shape obliquely；It is corresponded in hollow shaft and is respectively fixed with an oscillating deck at the fish block cleat assembly position of different height, oscillating deck is logical
It crosses support shaft to be fixed in hollow shaft, support shaft one end is fixed with hollow shaft by swivel bearing, bearing block, the support shaft other end
Stretching hollow shaft is outer, impregnates barrel outside weld is connected to oscillating rod, passes through swinging so that the fish block into hollow shaft orients for oscillating deck
Into in corresponding fish block cleat assembly, blanking chute is fixed with by rack above the hollow part of hollow shaft；Hollow shaft bottom
Portion is fixed on the output shaft of rotating electric machine；It is corresponded on impregnating cylinder inner wall and is fixedly arranged above one in each fish block cleat assembly
Flushing nozzle, all Flushing nozzles are connected with pump by pipe influx on same water inlet pipe, on water inlet pipe.
Compared with prior art, the beneficial effect that the present invention has is:
1, using deodorization soak of the invention, keep appropriateness temperature, oxygen and improve pH value, can effectively with generate fishy smell
Substance or react or combine or be allowed to lose activity or directly remove or odour masking；To achieve the purpose that smelling removal.
It can be widely used in various aquatic products；
2, it using related deodorization device of the invention, may be implemented slowly to revolve when impregnating deodorization with the speed of 0.1-0.5m/s
Turn hollow shaft, hollow shaft drives the rotation of fish block cleat assembly, deodorization liquid is pushed to form miniflow, passes through during miniflow impregnates
90 ° of rotating fish block cleat assembly improves the uniformity of deodorization within the same deodorization time, to optimize deodorization effect；
3, lead to after miniflow is soaked for a period of time and adjust the discharge that pH method further promotes fishy smell substance, then rushed and selected with warm water
And air-dry, to more effectively remove remaining fishy smell in the above process；
4, the design of special deodorization equipment is fed, it can be achieved that disposably passing through blanking chute hollow part into hollow shaft, entrance
Fish block enters in corresponding fish block cleat assembly under the action of oscillating deck, realizes automatic charging, while because fish block is in fish block folder
In board group part, deodorization substance is effectively prevent to deposit on fish block surface, guarantees the configuration of surface of fish block.
