Description

The processing method of the big silverfish of quick-frozen

Technical field: the invention belongs to food processing transportation technology field, be specifically related to the processing method for quick-freezing of a kind of big silverfish.

Background technology: silverfish (WhiteBait) is meant catfish seedling or brisling, has another name called silver bar fish, noodles fish, the residual fish of clam, plain rice fish.This small-sized silverfish normally in Mediterranean and the Atlantic Ocean catch.All have supply the whole year, but spring and summer during two seasons meat the most fertile.Fresh or frozen fish is all on sale.White is transparent slightly, and long only about 3 centimetres, entire body does not have squama, and one to property food applications as a whole i.e. (internal organ, head, wing etc. all do not remove, whole eating), and globality food is confirmed by international NI as a kind of natural " life prolonging food " at present.

Silverfish has big silverfish, Reganisalanxi, short kiss silverfish and few tooth weak point to kiss four kinds of silverfishes, and the above two are bigger, and both are less in the back.Whole fish is the stain except that two, and whole body is pure white, transparent, bone is soft, no squama.Concentrating on annual the middle ten days and the last ten days in mid-April to June term, is around here the busy season of fishing for.Silverfish is nutritious, and according to one's analysis, per 100 gram silverfishes contain protein 8.2 gram, fat 0.3 gram, carbohydrate 1.4 grams, 258 milligrams of calcium, 102 milligrams in phosphorus, 0.5 milligram of iron, 41 kilocalories of heats, and multiple nutrients compositions such as vitamin B1, B2, niacin.Fresh silverfish can be made into dried silver fiss through insolation, and its shape is as a tail jade hairpin, and color is prolonged constant.A mouthful dried silver fiss that produces is swung in Suzhou, and long body is flat less than two cun, and the fertile bone of meat is soft, and look has light in vain, classifies as top grade.Find a good sale in the America and Europe, enjoy high reputation.Silverfish meat exquisiteness, pure white fresh and tender, no spur, no fishy smell can be used to cook out the bright soup of multiple delicious good to eat dish.

Big silverfish extensively is distributed in master stream, the middle and lower reach of Yangtze River and attached lake in China, and its meat is tender delicious, and is nutritious, food a kind of special cucumber delicate fragrance arranged.General about 20 centimetres of big silver-colored fish length. no bone is stingless. and be the very high small-sized famous and precious fish of a kind of economic worth, at home and abroad market is well received.

Summary of the invention: the processing method that the objective of the invention is to propose the big silverfish of a kind of quick-frozen.

The present invention is achieved like this: processing method is mainly as follows: raw material processing+cleaning+draining+weighing+pack+dress box+quick-frozen+refrigeration; 1) raw material is checked and accepted: the raw material fish requires freshness fertilizer degree good, and bar shaped is complete, the true qualities color and luster, and eyeball is limpid, the muscle high resilience, no dirt mucus, fragrant obviously and free from extraneous odour unloads after the arrival immediately to job shop is rejected substandard products by the case inspection, free-hand grabbing by operating; 2) clean: with fish washer or manually float Xian, the big silverfish of adding is wanted evenly avoid the fish layer blocked up, clean with the phreatic water or the running water of cooling on the rocks back cleaning, picks up after cleaning several times repeatedly, and the front and back operation closely cooperates, and is overstocked; 3) pick inferior, draining: in the time of rinsing, remove the ice cube and the weeds that swim in the water surface, and pick out other fish and shrimp, the silverfish after the rinsing is put into the container that leaking hole is arranged at the bottom, draining 10-20 minute; 4) weighing: the big silverfish that drop is crossed water is by different size weighing pack, should look fish body size and drainage degree and adds and weigh 10%, goes in the carton silverfish is packed then, is emitted in the special-purpose frozen silver fiss dish quick freezing repository of in time making a gift to someone; 5) quick-frozen: silverfish coils that proper alignment is on the pipe support of quick freezing repository in order, and the quick freezing repository temperature should be dropped rapidly to below-25 ℃, after 15-16 hour, is freezing process and finishes when center temperature of fish reaches-15 ℃; 6) vanning and refrigeration: outbound immediately after quick-frozen finishes, the low temperature vanning, at the bottom of the carton, roof liner pad corrugated paper, external application binder bundle is beaten firmly, send into storage in the freezer immediately, cold store temperature should remain on-18 ± 2 ℃, stores and is no more than 12 months, freeze big silverfish central temperature when dispatching from the factory and be no more than-15 ℃, must transport with refrigerator car low temperature during the transhipment export trade.

The specific embodiment: the present invention is described in detail below in conjunction with embodiment.

Embodiment: 1) raw material is checked and accepted: the raw material fish requires freshness fertilizer degree good, bar shaped is complete, the true qualities color and luster, and eyeball is limpid, the muscle high resilience, no dirt mucus, fragrant obviously and free from extraneous odour, the raw material fish is unloaded immediately to job shop after arriving, reject substandard products by the case inspection, note free-hand grabbing, must guard against with hard device such as rake, spade, in order to avoid destroy the globality of fish body by operation; 2) clean: with fish washer or manually float Xian, the big silverfish of adding is wanted evenly avoid the fish layer blocked up. influence the rinsing quality, to clean with the phreatic water or the running water of cooling on the rocks back cleaning, pick up after the cleaning several times repeatedly, clean and want rapidly, the front and back operation closely cooperates, and can not overstock; 3) pick inferior, draining: in the time of rinsing, remove the ice cube and the weeds that swim in the water surface, and pick out other fish and shrimp, the silverfish after the rinsing is put into the container that leaking hole is arranged at the bottom, draining 10-20 minute; 4) weighing: the big silverfish that drop is crossed water packs by the different size weighing, must guarantee every bag of silverfish thaw net weight 500 grams or 1000 grams behind the drainage during weighing, therefore should look fish body size and drainage degree and add and weigh 10%, go in the carton silverfish is packed then, be emitted in the special-purpose frozen silver fiss dish, every dish is adorned 10 boxes, the quick freezing repository of in time making a gift to someone; 5) quick-frozen: silverfish coils that proper alignment is on the pipe support of quick freezing repository in order, and the quick freezing repository temperature should be dropped rapidly to below-25 ℃, after 15-16 hour, is freezing process and finishes when center temperature of fish reaches-15 ℃; 6) vanning and refrigeration: outbound immediately after quick-frozen finishes, low temperature vanning, every case 20 boxes. 10 kilograms or 20 kilograms of net weight.At the bottom of the carton, roof liner pad corrugated paper, external application binder bundle is beaten firmly, and indicates the name of an article, specification, weight, the date of production etc. send into immediately in the freezer and preserve.Cold store temperature should remain on-18 ± 2 ℃. and stack respectively by production batch, specification, store and be no more than 12 months.Freeze big silverfish central temperature when dispatching from the factory and be no more than-15 ℃, must transport with refrigerator car low temperature during the transhipment export trade.

The big silverfish of the inventive method processing does not have broken tripe or abdominal distention, does not have filthy mucus, and musculature is solid, and elasticity is good, and free from extraneous odour does not have yellow bar substantially; Freeze that piece is smooth, the ice clothing evenly, cleaning, calm dry oxidation and because of freezing the phenomenon that causes ice cube to turn black slowly, the silverfish form is fresh complete clear, shape is translucent.
