Abstract

The present invention relates to a processing method for aquatic products, particularly to a processing method for cutting octopuses into pieces, which has the advantages of particular process and good quality of products. After octopuses are cleaned, and the octopuses are cut from the positions between two eyes to the positions of teeth. Odorous octopuses are removed, the rest are kneaded with salt, and water which is left after the rest are kneaded with salt is removed. Secondary water and alum are added to the octopuses, after the octopuses are cleaned for the second time, the octopuses are blanched and cooled, and then the heads, the teeth, and the toes of the octopuses are removed, and the feet of the octopuses are divided. After the divided feet of the octopuses are cut into pieces, the pieces of the octopuses are sterilized, soaked and cleaned. The present invention has the advantages that raw material is carefully chosen, technological conditions and processing steps are optimized, the present invention ensures that octopuses become instant food, each nutrient component of products can be kept in maximum without the extraction of any chemical medicine, and octopuses prepared with the method of the present invention has fine quality in color, flavor, and taste and is convenient for people to eat, the products of the present invention have high added value and is suitable for the development and the industrial production of finishing processing products, a whole instant octopus is more suitable for various groups to deal with in other ways as required, and the products of the present invention have good economic and social benefits.

Description

Octopus cutting method

Technical field

The present invention relates to a kind of processing of aquatic products method, especially relate to a kind of processing method of octopus segment.

Background technology

Octopus is commonly called as eight band octopus, has 142 kinds at least, and China is one of its main place of production.Octopus is the high aquatic products of content of taurine in the food; reach 31.2 μ mol/g; be equivalent to 390mg/100g and (see document: Chen Yuzhen; content of taurine in the food; amino acid and living resources (J); 1994,4), exceed much than fruit, vegetables, seed, nut, cereal, meat, dairy produce and other marine products.Medium-sized and small enterprises science and technology magazine is the interim process of octopus being extracted natural taurine of having introduced at 2000 the 6th: it is clean to shell, and homogenate adds 3 times of water gagings and boils 1h; leach juice, residue adds water boil 0.5h, merges juice; concentrate, add HCl and transfer pH to 3, make the acidic protein precipitation; centrifugation; parting liquid transfers to pH to 10 with 20%NaOH, wash-out again, and fluid decompression in upper reaches concentrates; add ethanol, placement is separated out taurine and is recrystallized.

Existing octopus is difficult to control microbiological indicator because of being subjected to condition restriction such as process technology and process equipment, and nutrition runs off serious, color is inharmonious, converted products is difficult to be accepted by the consumer, therefore generally is difficult to cause added value of product low to its deep processing.

Summary of the invention

The objective of the invention is to be difficult to carry out deep processing at existing octopus, problem such as added value of product is low provides that a kind of technology is fastidious, the octopus cutting method of good product quality.This processing technology by dehydration, concentrate, effect such as enrichment, need not any chemicals to extract, can keep each nutritional labeling of product to greatest extent: amino acid content reaches 39.86%, and content of taurine is up to 1000-1950mg/100g.Its content is 3-5 times of general chemistry extraction method.

Step of the present invention is (content of raw material all calculates by mass ratio):

1), octopus is removed cleans dried earning behind the internal organ;

2), between the order of octopus and order, cut to the tooth position;

3), remove odorous octopus;

4), salt is rubbed;

5), the surplus water after removing salt and rubbing, add secondary water and alum again and continue to rub and wash;

6), clean;

7), the octopus of dropping into after cleaning in boiling water carries out blanching;

8), cooling;

9), decaptitate, tooth, toe;

10), divide foot;

11), segment;

12), cleaning and sterilizing;

13), dipping;

14), clean.

In step 4), the time that salt is rubbed is 15～40min, is preferably 25～35min; Octopus: water: salt=150: (100～200): (8～15) are preferably octopus: water: salt=150: 150: 12; Preferably with monosodium glutamate, its content is octopus: monosodium glutamate=1000: (0.5～2) is preferably octopus: monosodium glutamate=1000: 1.2.

In step 5), the content that adds secondary water and alum is octopus: secondary water: alum=150: (100～200): (0.5～1), rubbing the time of washing is 3～10min, is preferably octopus: secondary water: alum=150: 150: 0.75, rubbing the time of washing is 5min.

In step 7), the content of water is octopus: water=130: (550～700), the blanching time is 100～200s, is preferably octopus: water=130: 600, and the blanching time is 120～150s; During blanching preferably with salt, salt: octopus=(7～9): 150, be preferably salt: octopus=8: 150.

In step 8), preferably divide secondary cooling, cooling for the first time is with flowing water cooling 5～30s, the water temperature of cooling is preferably lower than 10 ℃ for the second time, be 25～60min cool time for the second time, when cooling off for the second time preferably with salt, acetic acid and V _c, octopus: salt: acetic acid: V _c=100: (1.2～2.2): (0.045～0.12): (0.07～0.2).

In step 11), every section best 2.5～12g.

In step 12), available 80PPM disinfectant sterilization 20～40s is preferably 30s.

In step 13), octopus: water: salt: acetic acid=100: 100: (1～1.5): (0.03～0.08), dip time 15～40min.

Therefore because the present invention is selected raw material has been optimized process conditions and processing step, obtains very outstanding effect:

1, product enters meticulous moldeed depth processing by roughing; make octopus become ready-to-eat food; need not any chemicals extracts; each nutritional labeling that can keep product to greatest extent: amino acid content reaches 39.86%; content of taurine is up to 1000-1950mg/100g; its content is 3-5 times of general chemistry extraction method; changed the high-load 2-tarine of original high protein for easily being absorbed by the people; it all has very big effect to softening blood vessel, reduction cholesterol, prolongation life; color, smell and taste are best in quality; instant enjoys people to like.

2, after tested, the safety and sanitation level height of the product after processing, total number of bacteria is about 1000/g, and pathogenic bacteria such as Escherichia coli are negative, and meet relevant quality requirement.

3, added value of product height: the present invention makes product develop into deep processing increment from former fish, is suitable for the exploitation and the industrialization of intensely processed products, and instant integral octopus is more suitable for each kind of groups and deals with in addition as required.Impel processing of aquatic products to develop to variation and high added value direction, its economical, societal benefits are self-evident.
