Embodiment 1

[0039] A deep-sea fish processing method for reducing purine and mercury content, in parts by weight, the specific steps are as follows:

[0040] (1) First mash 1 part of ginkgo fruit, 1.5 parts of celery and 0.5 part of okra into a slurry, squeeze out the liquid, filter to obtain the filter residue and filtrate, the filter residue enters step (2), and add 0.002 parts of bromelain and 0.001 part of Chinese okra to the filtrate Protease, enzymatic hydrolysis, enzyme inactivation, centrifugation to get the first supernatant, add 0.008 part of ferrous chloride to the first supernatant, chelate, centrifuge, get the second supernatant;

[0041] (2) Then the filter residue is vacuum freeze-dried for the first time, then poured into 6 parts of deionized water, ultrasonically dispersed for 20 minutes, vacuum freeze-dried for the second time, ultrafinely pulverized to obtain ultrafine powder, and then polyethylene glycol 400 is used to Hydrophilic modification of superfine powder to make...

Embodiment 2

[0059] A deep-sea fish processing method for reducing purine and mercury content, in parts by weight, the specific steps are as follows:

[0060] (1) First mash 1 part of ginkgo fruit, 2 parts of celery and 0.3 part of okra into a slurry, squeeze out the liquid, filter to obtain the filter residue and filtrate, the filter residue enters step (2), add 0.004 part of bromelain and 0.0008 part of Chinese okra to the filtrate Protease, enzymolysis, enzyme inactivation, centrifugation to take the first supernatant, add 0.01 part of ferrous chloride to the first supernatant, chelate, centrifuge, take the second supernatant;

[0061] (2) Then carry out the first vacuum freeze-drying of the filter residue, then pour it into 4 parts of deionized water, disperse it by ultrasonic wave for 30 minutes, vacuum freeze-dry it for the second time, and ultrafinely pulverize it to obtain superfine powder, then use polyethylene glycol 400 to Hydrophilic modification of superfine powder to make hyd...

Embodiment 3

[0079] A deep-sea fish processing method for reducing purine and mercury content, in parts by weight, the specific steps are as follows:

[0080] (1) First mash 1 part of ginkgo fruit, 1.8 parts of celery and 0.4 part of okra into a slurry, squeeze out the liquid, filter to obtain the filter residue and filtrate, the filter residue enters step (2), add 0.003 part of bromelain and 0.0009 part of Chinese okra to the filtrate Protease, enzymolysis, enzyme inactivation, centrifugation to get the first supernatant, add 0.009 part of ferrous chloride to the first supernatant, chelate, centrifuge, get the second supernatant;

[0081] (2) Then the filter residue is vacuum freeze-dried for the first time, then poured into 5 parts of deionized water, ultrasonically dispersed for 25 minutes, vacuum freeze-dried for the second time, ultrafinely pulverized to obtain ultrafine powder, and then polyethylene glycol 400 is used to Hydrophilic modification of superfine powder to make hydrophili...

Abstract

The invention provides a deep-sea fish processing method for reducing purine and mercury contents. The deep-sea fish is treated by a treatment solution prepared by using ginkgo nuts, celery and okra in the processing process, so that the purine and the mercury in the deep-sea fish are effectively removed, the purine and mercury contents in quick-frozen products are greatly reduced, and the ediblesafety of the deep-sea fish is ensured. The treatment solution is prepared by the following steps: firstly, mashing the ginkgo nuts, the celery and the okra into pulp, squeezing the pulp to obtain liquid, filtering the liquid to obtain filter residues and filtrate, carrying out enzymolysis treatment on the filtrate to degrade contained proteins into micro-molecular polypeptide or amino acid, chelating the micro-molecular polypeptide or the amino acid with ferrous ions to form chelate, and finally obtaining a second supernatant containing the chelate, as well as polysaccharide, nuclease, etc.;and carrying out primary vacuum freeze drying, water dispersion, secondary vacuum freeze drying and superfine grinding treatments on the filter residues to prepare superfine powder, and uniformly dispersing the superfine powder into the second supernatant after hydrophilic modification to form the treatment solution.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a deep-sea fish processing method for reducing purine and mercury content. Background technique [0002] Deep-sea fish belong to more than ten families. They are characterized by large mouths and large eyes, and light emitters on one or more parts of their bodies. They are found in teleost fish in the depths of the ocean. The light emitters are used not only to trap prey, but also to Seduce a spouse. Deep-sea fish live in the deep-sea area below 100 meters, so the fishing method can only be ocean deep-sea trawling deep-sea fish, or hook fishing, and then catch on board, and freeze in time, and because its main components are protein and polyunsaturated fatty acids, Therefore, under the storage state of -18°C, there will be no loss of nutrients, and the freshness and quality of air inversion can be well preserved. Compared with freshwater fish and offshore fish, the possi...
