Abstract

The invention relates to deep processing technology for manufacturing a crab essence product by pretreating, cooking, crushing, stirring, pelletizing eriocheir sinensis (Chinese mitten crab, Eriocheir sinensis) serving as a raw material, and salt, gourmet powder and the like serving as auxiliary materials and other steps. In the product, the content of crab meat and crab cream reaches over 15 percent; and the product has original characteristic flavor and characteristic sense of the crab, lasting and rich smell, and is convenient for preservation.

Description

A kind of production technology of Eriocheir sinensis crab highly finished product

Technical field

The present invention relates to a kind of production technology of Eriocheir sinensis crab highly finished product.

Background technology

The Eriocheir sinensis industry is Jiangsu Province's fishery products largest industrial sector, also is the main producing region of Chinese Eriocheir sinensis, the annual production of Jiangsu Eriocheir sinensis account for Chinese Eriocheir sinensis annual production about 70%.Jiangsu Province's Eriocheir sinensis cultured area reached 4,260,000 mu in 2007, and output reaches 250,000 tons, and the output value reaches 14,400,000,000 yuan.But,, easily corrupt because river crab has (1) high-moisture; (2) self hard first Li Ao is difficult to Mechanized Processing and handles; (3) seasonal strong, listing in a large number simultaneously; (4) local flavor easily scatters and disappears, difficult storage; Characteristics such as (5) small dimension (hair) crab utilization rate is low, relevant technical research and product rarely in report, appear on the market.In recent years, some Eriocheir sinensis breed processing enterprises in Taihu Lake, Jiangsu Province, Gehu lake, Gu Chenghu, basin, Hongchehu Lake have carried out certain technical research at the low present situation of middle small dimension Eriocheir sinensis utilization rate; Introduced technology such as fence is fresh-keeping, high-moisture is fresh-keeping, it is on sale that development product mainly contains little ancestor converted products market such as frozen crab, crab piece, wine preserved crab, crab lake.

The Eriocheir sinensis of China is cultured and is of long duration, even to this day as if on the development bottleneck of industry, draw close, product market price glides gradually, getting more and more of Eriocheir sinensis raiser loss, industrial transformation upgrading and high-tech cultivation demand are strong, thereby the deep processing industrialization seems even more important.The deep processing industrialization that Eriocheir sinensis crab (meat, Huang) is smart, high added value with realization characteristic aquatic products is a purpose, study by tackling problems in key technologies, develop novel healthy water product, return and sell in season, fill a hole in the market, prolong the breed processing industry chain of river crab, promote the development of local fishery economic.

Summary of the invention

The technical problem that solves

The problem that the present invention mainly solves is to utilize the river crab of small dimension to prepare the crab highly finished product with crab characteristic flavor on basis, characteristic color.

Technical scheme:

The technical step that the present invention relates generally to is as follows:

1, pre-treatment:

Get fresh and alive Eriocheir sinensis, carefully scrub the dirts of removing in crab shell, chela, the step such as silt.Crab is ripe.

2, adopt crab meat, crab oil:

Manual crab meat and the crab oil of stripping respectively.

3, the preparation of crab meat powder, crab oil powder:

Crab meat powder: after the crab meat drying of taking, be ground into powder with high speed disintegrator.

Crab oil powder: get standby crab oil, break into even pasty state with the high speed beater.

4, crab juice preparation:

Accessory substance crab shell, crab meat bits place the water of former boiling crab, continue to boil, and the flavor components such as free amino acid, aliphatic acid of crab are extracted, and become crab juice.

5, auxiliary material preparation:

Auxiliary material mainly contains sucrose, salt, monosodium glutamate, flavour nucleotide disodium (I+G), dextrin, cornstarch, and after 60 ℃ of oven dry, high speed disintegrator is pulverized (15000 rev/mins, 1 minute time), 40 order sieving for standby.

6, breading, granulation

Step 1: add salt and I+G earlier, add antioxidant (TBHQ), spice, crab perfume ingredient again, stir.

Step 2: add crab oil powder, monosodium glutamate, sucrose, anticaking agent, stir.

Step 3: add crab meat powder, cornstarch, dextrin, stir.

Step 4: add a small amount of crab juice in the mixed powder, granulation in granulator, the dry finished product that gets.

7, finished product packing

Finished product generally adopts polybag and iron flask to pack, and requires the packaging material must not be influential to the smart local flavor of crab.

The specific embodiment

1, pre-treatment:

Get fresh and alive Eriocheir sinensis, single weight 100g-150g, industrial water meet the requirement of " GB 5749 drinking water sanitary standards ", carefully scrub the dirts such as silt in crab shell, chela, the step.The crab of cleaning is placed food steamer, and 100 ℃ of boilings are about 15 minutes.

2, adopt crab meat, crab oil:

After crab to be cooked is cooled to room temperature, strip crab meat and crab oil respectively by hand, refrigerate standby.

3, the preparation of crab meat powder, crab oil powder:

The crab meat powder: the crab meat of taking placed in 60 ℃-65 ℃ the air dry oven, be dried to crab meat moisture about 15%, product shows slightly brown.Dried crab meat is pulverized (15000 rev/mins, 1 minute time), 40 order sieving for standby with high speed disintegrator.

The crab oil powder: get standby crab oil, foreign material such as manual removal black film break into even pasty state with high speed beater (15000 rev/mins, 1 minute time).

4, crab juice preparation

Get accessory substance crab shell, the crab meat bits that crab meat, crab oil produce and place the water of former boiling crab, cover completely and continue to boil 30 minutes, the flavor components such as free amino acid, aliphatic acid of crab are extracted, become crab juice, 80 orders filter, and crab juice (or concentrating the back) cooling is standby.

5, breading, granulation

Step 1: at first add salt and I+G, after mixer stirs, add antioxidant (TBHQ), spice, crab perfume ingredient, stir.

Step 2: add the crab oil powder, stir, next adds monosodium glutamate, sucrose, anticaking agent, stirs.

Step 3: add the crab meat powder, stir, add cornstarch, dextrin subsequently, stir.

Step 4: stir on the limit in mixed powder, and the limit adds a small amount of crab juice, stirs.Whole reinforced, the process that stirs, mix was finished with interior in about 15 minutes.

Step 5: shift out powder, granulation in granulator, about 30 minutes of 65 ℃ of-70 ℃ of dryings, 14 eye mesh screen vibration screening, finished product.

6, the smart formula for a product of crab

The smart formula for a product table of table 1 crab
