Abstract

The prsent invention utilizes waste produced by producing fish product and low-value small miscellaneous fishes, including fish head, fish bone, fish skin, fish scale, fin, fish tail, fish blubber and internal organ except fish gills and fish bile, as raw material and adopts the processes of preparing material, pulverizing, washing, drying, cooking, adding flavouring material, adding perfume to remove fishy taste, adding coagualting agent and stabilizing agent, and makes them into various fish products, such as fish jelly, fish vermicelli, fish flour, fish ball and fish soup material, etc. with rich nutrients, amino acids, protein and trace elements, of calcium and phosphorus, etc. necessary for human body.

Description

The processing method and the product of a kind of fish products leftover bits and pieces and low-value small fish

Technical field

The invention belongs to aquatic food and preparation method, the processing method and the product of particularly a kind of fish products leftover bits and pieces and low-value small fish.

Background technology

At present, leftover bits and pieces and low-value small fish after the fish products processing because of no edibility, and have special stench flavor, remove raw meat and handle complexity, and the cost height is used for producing fish meal, fish oil, feed more or makes industrial raw material.A large amount of edible nutritional resources are wasted and cause environmental pollution easily.Once useful fish scale is partly made the report of enriched fish scale juice in the prior art, but fish scale is the few part in the leftover bits and pieces, does not fundamentally solve wasting of resources problem.Yet there are no the whole leftover bits and pieces (except the fish cheek, the fish courage) that utilize after fish are processed by retrieval and make raw material, carry out the method for deep processing and food prepared therefrom.

Summary of the invention

The invention provides a kind of deep working method and reach according to this and the food of production, to improve stock of fish utilization rate fish products leftover bits and pieces and low-value small fish.

For reaching above-mentioned purpose, adopted following technical scheme:

1, get the raw materials ready and pulverize: raw materials used for the head of fish, bone, skin, squama, fin, tail, fat, internal organ (except the cheek, the courage) and there is not the small fish of edibility, above-mentioned raw materials is cut into about 2cm ²Fine grained chippings.

2, rinsing and draining: after fragment raw material water is cleaned up, be about ethanol 2%, soaked 10 minutes in the mixed aqueous solution of acetic acid 5% in concentration, use the clear water rinsing white only again, no mucus, no dirt to fish matter, no watery blood, the mucus of molten peeling fish skin, fish body, drain well then;

3, spices dipping; Pulverize spices such as ginger, cloves, fennel, three naphthalenes a little that decocting boils, mix evenly, flooded 15 minutes with the raw material that drains.The spices consumption is decided on the source and the kind of raw material.

4, decoct: with the raw material of dipping in 1:(3～5) ratio add water, insert in the sealed high-pressure vessel and decoct about 120 ℃ of decoction temperature, pressure about 10.30 * 10 ⁴Pa is advisable, and about 20 minutes of time, allows more nutrition hydrolysis.If need the more calcium of stripping, can add acetic acid in right amount.

5, filter: elimination bone slag and insoluble matter, remove oil slick, filtered fluid is natural coagulation at normal temperatures, and this liquid can be used as fish tundra slurry.

6, modulation: freeze system's food with obtaining fish behind above-mentioned magma adding flavor enhancement, coagulating agent, the stabilizing agent, encapsulate at last.

Modulator approach:

A, work make things convenient for fish to freeze: fish tundra slurry is added citric acid, transfer PH3.5～4.2 scopes, add fruit juice or essence, milk powder or fresh milk etc., be packaged in the jelly cup with flavor enhancement, coagulating agent (Na-alginate, gelatin, agar etc.).After solidifying, under 50 ℃, then do not freeze or the fruit juice fish is frozen and other flavor fish is frozen for the fruity fish from dissolving;

B, make the snack dish: fish tundra slurry is transferred about PH6 with edible sodium hydroxid, added salt, sugar, monosodium glutamate, flavoring, starch, soybean protein etc., mix well, cook gelatinization;

C, add corresponding filler, excipient (flour, starch, dextrin etc.), can develop more widely fish and freeze series food (as: fish meal silk, fish face, fish agar, fish soup material etc.) by fish tundra slurry.

Advantage of the present invention:

1, the leftover bits and pieces with fish is a raw material, and processing factory is supporting with fishery-ies product, can turn waste into wealth, and additional income has reduced waste, has saved resource, has also solved problem of environmental pollution simultaneously, can create than large economy benefit and social benefit.

2, not have raw meat odorless mouthfeel good for this cold fish jelly food, and nutrition is complete, contains natural components such as necessary amino acid of human body and protein and calcium, squama, is easy to absorption of human body, has improved the value of fish.

3, this fish was both frozen and can make instant food, can make the snack dish again, also can be used for culture of bacteria as peptone.

Embodiment

The preparation embodiment of fish tundra slurry:

Get the leftover bits and pieces of 10kg silver carp or other fish, stripping and slicing is pulverized and is 2cm ²Size, the acetic acid mixed aqueous solution of putting into 2% ethanol and 5% soaked 10 minutes, went mucus, watery blood fair and clear to fish matter with the clear water rinse, no dirt, taking-up drain well.With cloves 5g, each 5g of fennel, three naphthalene 3g, 10 liters of ginger 100g crushing and water-addings, decoct out fragrance slightly, soak rinsing and drained raw material 15～20 minutes, add water to 3～5 times of raw material, insert and carry out the high temperature decoction in the high-pressure bottle, temperature is about 120 ℃, and pressure is 10.30 * 104Pa, decocts 25 minutes to osteomalacia, fish scale is rolled, and soup juice is strong and do not have fishy smell.Filter juice with double gauze, treat cold slightly, remove degrease and can obtain magma.This magma is modulated by aforementioned manner, can obtain required fish slurry series food.

Claims

1, the processing method and the product of a kind of fish products leftover bits and pieces and low-value small fish, successively through the pulverizing of getting the raw materials ready, rinsing drain, decoct, operation such as modulation processes, it is characterized in that: raw materials used for the head of fish, bone, skin, squama, fin, tail, fat, internal organ (except the cheek, the courage) and there is not the small fish of edibility; Raw material also must flood with spices before decocting operation after rinsing drains, and the concrete practice is that ginger, cloves, fennel, three naphthalenes, four flavor spices are pulverized, and boiling is mixed evenly with the raw material that drains, and floods 15 minutes in order to remove its stench flavor.
