Background
Antarctic krill is a single organism that lives on the earth in Antarctic, is known to be the most abundant resource, is nutritious, and is called the largest animal protein pool on earth. According to statistics, the biological resource amount of the antarctic krill is about 6-10 million tons, and meanwhile, about 3.42-5.36 million tons of shrimps can be bred every year. The fishing of the antarctic krill is started in the 60 th 20 th century abroad, and the fishing of the antarctic krill is firstly carried out in 2009 in China. The fishing place is far away from the Antarctic sea area, and the Antarctic krill is rich in low-temperature autolytic enzyme, so that quick freezing after fishing is an important method for preserving the Antarctic krill. However, due to the distance factor of the fishing place of the antarctic krill, the freezing storage time of the antarctic krill is far longer than that of common aquatic products, in the long-term freezing storage process, the growth of a large number of irregular ice crystals can influence the binding state between protein molecules and binding water, part of the binding water is separated and converted into the ice crystals, so that the interaction between the water and the protein is caused, the original tissue structure of the protein is influenced, and meanwhile, the protein denaturation causes the reduction of water retention, and the thawing yield and the product processing quality of the antarctic krill are influenced.
The antifreeze is a substance which is added into food and can prevent the food from being frozen and damaged so as to achieve the effect of long-time preservation, glycerol is firstly added into aquatic products in Japan to prevent protein denaturation in the aquatic products, and at present, phosphate and sucrose or sorbitol are used as the antifreeze. Phosphate such as sodium tripolyphosphate, sodium hexametaphosphate, sodium pyrophosphate or a mixture thereof and other phosphorus-containing antifreeze are used as the freezing protection of aquatic products, the addition amount of the phosphate needs to be strictly controlled, and the additive effect generated by eating various aquatic products for a long time can also cause excessive phosphorus intake to influence the calcium-phosphorus balance of a human body and harm the health; sucrose and sorbitol are not beneficial to obese patients and diabetic patients due to their high sweetness and high glycemic index. Therefore, in consideration of the current healthy consumption trend and some special groups, the development of a novel composite antifreeze agent which is green and healthy and is suitable for antarctic krill is of great significance.
Terahertz wave is specially designated 1011～1013Hz, the wavelength is 30 um-3 mm, and the electromagnetic wave, water molecule group and various micro-particles between microwave and infraredAnd molecules and the like absorb the terahertz waves and generate same-frequency resonance with self vibration waves, and the dissolving capacity of water is enhanced under the action of the same-frequency resonance waves.

Comparative example 10
The specific implementation steps are as follows: soaking 500g of Antarctic phosphorus shrimp meat in 1000g of solution for 1h at 4 ℃, and draining water after soaking; the solution is purified water without any added antifreeze component.
The Antarctic krill soaked and drained in the examples and comparative examples of the present invention was used as a sample and stored in a freezer at-18 ℃ for 3 months.
Index measurement:
(1) thawing loss rate: namely, after each sample is frozen and stored for 3 months, the sample is completely thawed at 4 ℃, and the quality changes before and after thawing. The lower the thawing loss rate, the less juice loss and the lower the loss.
Thawing loss rate (mass before thawing-mass after thawing)/mass before thawing × 100%
(2) Water retention: namely, after each sample is frozen and stored for 3 months, the sample is completely unfrozen at 4 ℃, the surface moisture is wiped off, and the sample is centrifuged for 20min at 3000g, and the mass changes before and after centrifugation. The smaller the mass change value before and after centrifugation, the larger the water holding capacity, indicating that the water holding capacity of antarctic krill after frozen storage is better.
Water holding capacity is defined as mass after centrifugation/mass before centrifugation × 100%
Data for thaw loss and water retention reflect the degree of protein denaturation from the side.
Thus, table 1 was prepared: thawing loss rate and water retention of each example and comparative example
Table 1: thawing loss rate and water retention of each example and comparative example
Comparative example 8 is a conventional common antifreeze, comparative example 7 is a commercial antifreeze, and the literature shows that trehalose has a sweetness of about 45% of that of sucrose, and is slowly absorbed in vivo and has a gentle glycemic response.
As can be seen from table 1, the thawing loss rate of the samples treated by the examples of the present invention was controlled to be 10% or less after 3 months of freezing, which is generally lower than that of each comparative example; the water binding capacity is more than 70 percent, and is generally higher than that of a comparative example. From the data of the thawing loss rate and the water retention, the most preferred example is example 3, which has a thawing loss rate of 6.6%, which is much lower than comparative example 10 as a control, and a water retention of 77.3%, which is much higher than comparative example 10 as a control, and which is superior to the conventional formulation of antifreeze (comparative example 8) and the commercial antifreeze (comparative example 7), and also has a significant enhancing effect compared to example 1 which has the same formulation but is not subjected to the terahertz treatment. From the viewpoint of formulation rationality and industrial production cost, the most preferable example is also example 3, while the formulation is more complicated, and the effect of comparative example 9 in which more different components are added is not remarkable, much less superior than example 3.
Therefore, the composite antifreeze agent suitable for the antarctic krill and the application thereof can better slow down the protein denaturation of the antarctic krill in the freezing process, protect the protein structure, reduce the juice loss per se and enhance the water holding capacity; the method can reduce the cost loss in the industrial production and transportation processes, improve the processing characteristics, improve the processing quality of subsequent products, and has the characteristics of safe components, low sweetness and simple use method.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
