Embodiment 1

[0032] A method for quick deacidification of Peruvian squid assisted by ultrasonic waves, the method steps are as follows:

[0033] (1) Thaw the frozen squid at room temperature to a semi-thawed state, remove the skin and viscera, wash the squid carcass with clean water, drain and cut into slices with a thickness of 10mm, and set aside;

[0034] (2) Mix sodium carbonate, sodium citrate, sodium pyrophosphate, sodium tripolyphosphate, and table salt in an appropriate proportion, add an appropriate amount of deionized water, stir well to fully dissolve, and prepare a mass percentage concentration of 0.5% pyrophosphoric acid Sodium, 0.3% sodium carbonate, 0.5% sodium citrate, 0.5% sodium tripolyphosphate, and 1% table salt are used to remove acid, for later use;

[0035] (3) Add the squid slices obtained in step (1) to the deacidification solution prepared in step (2) according to the ratio of material to liquid 1:2, and first ultrasonically treat it for 60 minutes, and the ultras...

Embodiment 2

[0042] A method for quick deacidification of Peruvian squid assisted by ultrasonic waves, the method steps are as follows:

[0043] (1) Thaw the frozen squid at room temperature to a semi-thawed state, peel off the skin and internal organs, etc., wash the squid carcass with clean water, drain and cut into slices with a thickness of 20mm, and set aside;

[0044] (2) Mix sodium carbonate, sodium citrate, sodium pyrophosphate, sodium tripolyphosphate, and table salt in an appropriate proportion, add an appropriate amount of deionized water, stir well to fully dissolve, and prepare a mass percentage concentration of 0.5% pyrophosphoric acid Sodium, 0.3% sodium carbonate, 0.5% sodium citrate, 0.5% sodium tripolyphosphate, and 1% table salt are used to remove acid, for later use;

[0045] (3) Add the squid slices obtained in step (1) to the deacidification solution prepared in step (2) according to the ratio of material to liquid 1:3, first ultrasonic treatment for 40 minutes, and t...

Embodiment 3

[0049] A method for quick deacidification of Peruvian squid assisted by ultrasonic waves, the method steps are as follows:

[0050] (1) Thaw the frozen squid at room temperature to a semi-thawed state, peel off the skin and internal organs, etc., wash the squid carcass with clean water, drain and cut into 5mm thick slices, and set aside;

[0051] (2) Mix sodium carbonate, sodium citrate, sodium pyrophosphate, sodium tripolyphosphate, and table salt in an appropriate proportion, add an appropriate amount of deionized water, stir well to fully dissolve, and prepare a mass percentage concentration of 0.5% pyrophosphoric acid Sodium, 0.3% sodium carbonate, 0.5% sodium citrate, 0.5% sodium tripolyphosphate, and 1% table salt are used to remove acid, for later use;

[0052] (3) Add the squid slices obtained in step (1) to the deacidification solution prepared in step (2) according to the ratio of material to liquid 1:1, and first ultrasonically treat it for 30 minutes, and the ultra...

Abstract

The present invention belongs to the field of aquatic product processing and mainly relates to an ultrasonic wave assisted rapid acid removal method of Peruvian squids. Firstly, frozen Peruvian squids are semi-thawed, the thawed squids are peeled, internal organs are removed, the treated squids are washed, the washed squids are cut into slices, an acid removal liquid is added (the acid removal liquid consists of sodium pyrophosphate at a mass percentage concentration of 0.2-0.8%, sodium carbonate at 0.1-0.5%, sodium citrate at 0.2-0.8%, sodium tripolyphosphate at 0.2-1% and edible salt at 0.5-2%), the squids are firstly pretreated with ultrasonic wave, then the pretreated squids are soaked and rinsed, and after the soaking, the squids are rinsed with running water. The method is simple in technology and convenient in treatment, can also effectively improve the sour taste and bitter taste of the Peruvian squids, and improves the product quality of the squid products.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and in particular relates to a method for quick deacidification of Peruvian squid assisted by ultrasonic waves. Background technique [0002] Peruvian squid, commonly known as the American giant red squid, belongs to the family Squididae ( Ommastrephidae ) American squid ( Dosidicus ). The squid has a large body and grows rapidly. It is one of the largest and most abundant squid species discovered so far. Peruvian squid is a high-protein, low-fat aquatic product. It is also rich in vitamins, calcium, iron and other minerals. Its color, meat quality, and flavor are similar to abalone, but the price is low. The proportion of edible parts is higher than that of ordinary squid. The edible portion of fish was about 20 percent higher. But the Peruvian squid accumulates a lot of lactic acid and NH 4 Cl, lead to the obvious sour taste of squid muscle, which seriously affects its taste and ...
