Abstract
The invention provides a heavy metal remover which comprises, by mass, 25-30 parts of sodium gluconate, 25-30 parts of sodium acetate, 25-30 parts of sodium citrate and 5-10 parts of sodium carbonate. The invention further provides a method for removing heavy metal in fishy products by the heavy metal remover. The ingredients of the heavy metal remover, namely sodium gluconate, sodium acetate, sodium citrate and sodium carbonate, are all natural and safe food additives harmless to human beings. The method includes making soak solution by the heavy metal remover and soaking fishy products in the soak solution. By the method, more than 50% of heavy metal in fishes can be removed. Accordingly, the method is simple and effective.
Description
Technical field
The present invention relates to fish products, particularly relate to heavy metal removing agent and utilize the method for heavy metal in its elimination fish products.
Background technology
Along with the modern development of industrial or agricultural, the discharge of municipal domestic waste and Industrial " three Waste " is increasing, industrial wastewater containing various chemical toxicants enters rivers,lakes and seas in a large number, heavy metal contaminants is constantly accumulated and is enriched with in fish body, human body is entered finally by food chain, human body is worked the mischief, and therefore, how removing the heavy metal in fish products becomes countries in the world all questions of common concern.
In traditional elimination fish products, the method for heavy metal has: adopt non-food stuff additive that fish products is processed, but treatment effect is bad, and bringing secondary pollution to fish products, these non-food stuff additives enter human body and can human body be worked the mischief equally.
Summary of the invention
Based on this, it is necessary to for Problems existing in background technology, it is provided that a kind of efficient, safe, harmless heavy metal removing agent.
Additionally, the present invention also provides for a kind of utilizing the method for heavy metal in above-mentioned heavy metal removing agent elimination fish products.
A kind of heavy metal removing agent, in mass fraction, composed of the following components:
Sodium gluconate 25 ~ 30 parts;
Sodium acetate 25 ~ 30 parts;
Sodium citrate 25 ~ 30 parts;
Sodium carbonate 5 ~ 10 parts.
A kind of utilize the method for heavy metal in above-mentioned heavy metal removing agent elimination fish products, comprise the following steps:
The sodium gluconate of 25 ~ 30 mass parts, the sodium acetate of 25 ~ 30 mass parts, the sodium citrate of 25 ~ 30 mass parts and the sodium carbonate of 5 ~ 10 mass parts are mixed, obtains heavy metal removing agent;
By soluble in water for described heavy metal removing agent, obtain soak;
Fish products being put in described soak and soak 12 ~ 14 hours, taking-up drains away the water, the fish products after being processed.
Wherein in an embodiment, in described soak, heavy metal removing agent is 1 ~ 1.5:100 ~ 120 with the mass ratio of water;
Wherein in an embodiment, described fish products is 1 ~ 1.2:5 ~ 8 with the mass ratio of water in described soak.
Wherein in an embodiment, described heavy metal is one or more in cadmium, lead, arsenic, hydrargyrum.
Above-mentioned heavy metal removing agent is made up of sodium gluconate, sodium acetate, sodium citrate and sodium carbonate, is all food additive natural safely, harmless.
Additionally, heavy metal removing agent is made soak, fish products is put into and wherein soaks, just can by the heavy metal removing of more than 50% on fish body, simple, efficiently, and without influence on the voluptuousness of fish body and mouthfeel.
Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below the specific embodiment of the present invention is described in detail. Elaborate a lot of detail in the following description so that fully understanding the present invention. But the present invention can implement being much different from alternate manner described here, and those skilled in the art can do similar improvement when without prejudice to intension of the present invention, therefore the present invention is by the following public restriction being embodied as.
A kind of heavy metal removing agent, is made up of the sodium gluconate of 25 ~ 30 mass parts, the sodium acetate of 25 ~ 30 mass parts, the sodium citrate of 25 ~ 30 mass parts and the sodium carbonate of 5 ~ 10 mass parts.
In this heavy metal removing agent, sodium gluconate, sodium acetate, sodium citrate, sodium carbonate are the food additive that safety is natural, harmless.
A kind of utilize the method for heavy metal in above-mentioned heavy metal removing agent elimination fish products, comprise the following steps:
S110, by the sodium carbonate mixing of the sodium gluconate of 25 ~ 30 mass parts, the sodium acetate of 25 ~ 30 mass parts, the sodium citrate of 25 ~ 30 mass parts and 5 ~ 10 mass parts, obtain heavy metal removing agent.
S120, by soluble in water for above-mentioned heavy metal removing agent, obtain soak.
Wherein, in soak, the mass ratio of heavy metal removing agent and water is 1 ~ 1.5:100 ~ 120.
Preferably, in soak, the mass ratio of heavy metal removing agent and water is 1:100.
It is appreciated that, in in immersion, the height of heavy metal removing agent concentration can be allocated according to the content of heavy metal on fish body, the important indicator that in soak, the height of heavy metal removing agent concentration will be elimination heavy metal, the heavy metal that can remove when concentration height is also more many, and the heavy metal removed when the concentration is low is more few.
S130, fish products is put in above-mentioned soak soak 12 ~ 14 hours, taking-up drains away the water, the fish products after being processed.
Wherein, fish products is 1 ~ 1.2:5 ~ 8 with the mass ratio of water in soak.
Preferably, fish products is 1:5 with the mass ratio of water in soak.
It should be noted that above-mentioned immersion is to be completely submerged in soak by fish products, fish products is more little with the more big then removal effect of mass ratio of water in soak, and the more little then removal effect of mass ratio is more big.
Adopting atomic absorption instrument, detect by GB heavy metal detection method, in the fish products after adopting heavy metal removing agent to process, on fish body, the heavy metal of more than 50% obtains elimination.
In the present embodiment, heavy metal is one or more in cadmium, lead, arsenic, hydrargyrum.
Above-mentioned utilize the method for heavy metal in heavy metal removing agent elimination fish products, adopt the scientific matching of these simple ion chelating agents in heavy metal removing agent, the mode exchanged by ion makes the heavy metal ions removal in fish body out, reduce the content of heavy metal, simply, efficiently, the heavy metal of more than 50% on fish body can be removed.
It it is below specific embodiment.
Embodiment 1
30g sodium gluconate, 30g sodium acetate, 30g sodium citrate and 10g sodium carbonate are mixed, obtains heavy metal removing agent.
1g heavy metal removing agent is dissolved in 100g water, makes soak.
20g fish products is put in above-mentioned soak and soak 12 hours, take out, drain away the water, the fish products after being processed.
Adopting atomic absorption instrument by GB heavy metal detection method, the fish products adopting heavy metal removing agent to process front and back to be detected, its result is in Table 1.
Table 1 fish products processes the content of front and back heavy metal
As can be seen from Table 1, no matter being ocean fishes or fresh-water fishes, the fish products after adopting heavy metal removing agent to process, on fish body, the heavy metal of more than 50% is obtained for elimination, and the content of beary metal of the fish products after process meets the requirements.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
