Embodiment 1

[0024] A processing method of frozen cut octopus, the steps are as follows:

[0025] 1) Use fresh octopus, which requires good freshness, normal smell, natural octopus color and no serious mechanical damage, and the octopus should be guts removed;

[0026] 2) Rough washing: Use the same amount of water as the raw material to wash in a rolling washing machine for 10 minutes;

[0027] 3) Salt rubbing treatment: add 3% salt, 0.2% alum, and then add 5% water, and stir for 40 minutes in a rolling salt rubbing machine;

[0028] 4) Wash the octopuses one by one with running water on a special washing table, and remove the sand in the suction cup;

[0029] 5) Remove the head and neck: Cut the octopus's head and lower feet with a knife;

[0030] 6) Carry out blanching treatment: boil for 120 seconds in 95~100℃ water;

[0031] 7) Cool the boiled octopus in ice water below 10°C for 15 minutes, so that the temperature of the octopus center reaches 15°C or less;

[0032] 8) Step 7) Cut the eight legs o...

Embodiment 2

[0038] A processing method of frozen cut octopus, the steps are as follows:

[0039] 1) Use frozen octopus as raw material. The octopus requires good freshness, normal smell, natural octopus color and no serious mechanical damage. The frozen raw material is thawed in a thawing machine and the octopus is removed by hand;

[0040] 2) Rough washing: Use the same amount of water as the raw materials to wash in a rolling washing machine for 12 minutes;

[0041] 3) Salt rubbing treatment: add 3.5% of the raw material mass, and then add 6% water and stir for 45 minutes in a rolling salt rubbing machine;

[0042] 4) Wash the octopuses one by one with running water on a special washing table, and remove the sand in the suction cup;

[0043] 5) Remove the head and neck: Cut the octopus's head and lower feet with a knife;

[0044] 6) Cut the eight legs of the lower foot into pieces and cut into pellets according to the specifications;

[0045] 7) Rinse the diced octopus with clean running water, and...

Abstract

A processing method of frozen diced octopuses comprises the following steps: 1) removing internal organs of octopuses, performing crude washing; 2) performing salt-coating treatment; 3) cleaning the octopuses one by one, removing sand in sucking discs; 4) removing heads and necks; 5) performing blanching treatment; 6) cooling the boiled octopuses to reach a central temperature of less than 15 DEG C; 7) cutting and dicing the lower eight feet of each octopus treated in step 4) or step 6); 8) rinsing the diced octopuses, freezing in a single freezing machine below -30 DEG C to reach a central temperature of less than -18 DEG C; 9) weighing, coating with ice, and packaging to obtain the frozen raw diced octopuses or frozen blanched diced octopuses. The preparation technology of the invention is simple, reasonable, and easy to operate; the prepared frozen diced octopuses is not only convenient for eating, excellent in sensory indexes, good in color and taste, but also stable in product quality, and long in shelf life, has the characteristics of health, safety, and nutrition, not only enriches the kinds of octopus processing products, but also has great significance on promoting the development of aquaculture industry.

Description

Technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a processing method of frozen cut octopus. Background technique [0002] Octopus (English name octopus), also known as stone dwelling, octopus, sitting octopus, stone sucking, watching tide, dead cow, belongs to the octopod of the mollusk phylum Cephalopod, and is the general name of the octopod cephalopod. Because there are eight wrists on the head, and there are membranes between the wrists, which are of different lengths, there are two rows of sessile suction cups on the wrists, and the suction cups have no handles, so they are called "eight wrists." [0003] Octopus is rich in protein, minerals and other nutrients, and is also rich in anti-fatigue, anti-aging, and can extend human life and other important health factors-natural taurine. "Compendium of Materia Medica" records: "The octopus and the stone distance are two things, like a squid, but the taste is more ...
