1, octopus whole processing method, characterized by the following raw materials are calculated according to the mass ratio, the steps are: 1) sorted according to specifications; 2) remove the viscera and then wash, wash the surface of the mud and sand and adherents; 3) in the eyes and eyes between the incision to the teeth position; 4) removal of smelly octopus; 5) salt kneading, according to the octopus: water: salt: monosodium glutamate = 150:120 ~ 180:8-15:0-0.2, the time 10 ~ 40min; 6) remove the remaining water after salt kneading, and then add secondary water and alum, the amount of water and alum for the octopus. Time 10 ~ 40min; 6) remove the residual water after salt kneading, and then add the second water and alum, add the amount of water and alum amount of octopus: water: second water: alum = 150:120 ~ 180:0 ~ 0.8, kneading and washing for 3 ~ 8min; 7) cleaning; 8) reconfirm the odor, to remove the odor of the octopus; 9) according to the specifications of the requirements of the sorting; 10) rinsing, in the boiling water into the octopus, add salt, the salt amount is The amount of salt is 0.8% to 1.5% of the amount of water, time is 1 to 6min; 11) cooling, first with running water for the first time to cool, and then use the water temperature is lower than 10 ℃ and add salt, acetic acid, Vc water for the second time to cool, octopus: water: salt: acetic acid: Vc = 100:80-120:0.8-1.5:0-0.075:0-0.15, the second time to cool time is 30 to 60min; 12) cleaning and sterilizing for 20-50s; 13) controlling the residual water; 14) weighing and arranging the plate; 15) quick-freezing at a temperature <-35℃.
