Food Safety Risk Analysis: Scientific Interpretation on the Use of Yufuling in Aquatic Products

What is Fish Floating? What are the possible risks of using Yufuling in aquatic products? Recently, media reports mentioned that fish floating spirit may be added in the process of aquatic product cultivation and transportation
.
A few days ago, the State Food and Drug Administration released the 16th issue of “Food Safety Risk Analysis” in 2015, organizing relevant experts to interpret the fish floating spirit used in aquatic products
.
(1) What isYufulingYufuling is commonly known as "solid hydrogen peroxide", and its product names include granular oxygen, large granular oxygen, and solid oxygen-increasing tablets
.
The main ingredient of this type of product is generally sodium peroxycarbonate, mostly in the form of tablets, and a small amount is sold in the form of powder
.
After being put into water, Yufuling will be hydrolyzed into sodium carbonate and hydrogen peroxide.
At this time, sodium carbonate will increase the pH value of the water.
Under the alkaline condition of hydrogen peroxide, it is easier to release oxygen, thereby increasing the dissolved oxygen in the water
.
The role of Yufuling is generally to increase oxygen in an emergency.
When it is continuously cloudy or the light is strong, you can control the balance of microorganisms in the water body and improve the water quality by adding this type of chemical oxygenator
.
During the transportation of live aquatic products, the use of fish floating spirit can quickly provide fish, shrimp, crabs, etc.
with the necessary and sufficient oxygen for their respiration, which not only prolongs their lives, but also makes them sluggish due to lack of oxygen.
The fish and shrimps become active
.
(2) Whether the decomposition products of Yufuling meet the national standard.
There is no relevant national standard for Yufuling oxygen-enhancing products, and because they do not have the function of treating fish diseases, they cannot be treated as a fishery medicine in a strict sense
.
However, from the perspective of its main decomposition product hydrogen peroxide, it meets the relevant national standards
.
China’s Ministry of Agriculture Announcement No.
235 "Maximum Residue Limits of Veterinary Drugs in Animal Foods" stipulates that hydrogen peroxide is a "drug that is allowed to be used in animal foods but does not require a residue limit"; China’s National Food Safety Standards for the Use of Food Additives "Standard" (GB 2760-2014) stipulates that hydrogen peroxide is a "processing aid that can be used in all kinds of food processing, and the residual amount does not need to be limited
.
"(3) What are the possible risks of using Yufuling in aquatic products?From the perspective of public opinion, it is believed that Yufuling has two main safety risks
.
One is that some of the hydrogen peroxide and sodium carbonate produced by the decomposition of Yufuling in the water body may be absorbed by the fish's body surface or enter the muscles through the gills, which poses hidden dangers
.
In fact, these two substances generally have no negative impact on the quality and safety of fish products, and there is currently no experimental evidence and reason that fish floating spirit can cause harm to the human body
.
The second is that as a chemical, Yufuling may contain heavy metals such as lead and arsenic, which poses hidden dangers
.
Some unscrupulous traders may use sodium peroxycarbonate, a chemical product that does not meet the requirements, to replace fish floats.
In this case, there may indeed be a risk of introducing harmful ingredients such as heavy metals
.
However, the area of ​​fishing ponds generally ranges from 10 to 200 acres, and the water body is large.
To achieve the long-term aeration effect of the whole pond, the cost of using fish-floating chemical oxygenators to increase oxygen is much higher than that of commonly used machinery.
Method to increase oxygen, so the use time of Yufuling is usually short, and the dosage is relatively small
.
In the process of transportation and circulation, the use time of Yufuling chemical oxygenator is generally relatively short
.
Since it takes some time for heavy metals to accumulate in fish, overall the risk of heavy metal residues caused by the use of fish floating spirit is not high
.
　　Therefore, experts suggest that the formulation and revision of relevant regulations and standards for fish floating spirit fishery inputs should be further promoted, and corresponding national standards, industry norms, use and circulation requirements, etc.
should be formulated to standardize industrial development, ensure food safety, and improve consumers’ awareness of aquatic products.
Trust in quality and safety
.
At the same time, carry out risk monitoring of Yufuling products, investigate and deal with the illegal acts of replacing Yufuling as a fishery input with sodium peroxycarbonate produced from industrial-grade raw materials, and eliminate hidden risks
.
The safety risks brought by the use of Yufuling in the breeding and circulation of aquatic products are limited.
Consumers do not need to worry too much, but only pay attention to buying aquatic products through formal channels
