It is reported that Hongze County, Huai'an City, Jiangsu Province has a professional cooperative of freshwater products cultured by the lake. The company uses the “micro-frozen fresh-keeping†technology production line to clean and package the products such as grass chicken and silver fish into bags and finally into the cold storage. Through this "micro-frozen preservation" technology, the cell membrane in the food is not frozen and cracked, and the organism is in a micro-frozen state, and then the food is kept fresh by refrigeration. Compared with traditional freezing, the products after “micro-frozen†can maintain their fresh quality after long-term storage and transportation.
The live fish is quickly frozen into "ice sputum" by "fresh frozen liquid". It can be slowly moved by putting it into normal temperature water. Because it can make the cell membrane of frozen food not rupture, it can still be kept after long time storage and transportation. Fresh quality, this new "micro-frozen preservation" technology has received extensive attention at home and abroad in recent years. The Lake Fresh Aquatic Products Breeding Professional Cooperative located at the intersection of Ninghuai Expressway in Sanhe Town has such a “micro-frozen preservation†technology production line. A few days ago, the reporter went into the lake freshwater product breeding professional cooperatives to find out.
In the cooperative's processing workshop, the workers are busy cleaning and packaging the products such as grass chicken and silver fish. After packaging, a bag of grass chicken and silver fish are packed into the cold storage. Sun Jun, the chairman of the cooperative, told the reporter: "These are all products that are to be frozen. Unlike ordinary freezing, these products are still authentic even after half a year or even a year. This is our advantage."
Sun Jun’s Lake Freshwater Aquaculture Professional Cooperative was established in April 2012. It is mainly engaged in the processing, storage, transportation and sales of Hongze Lake aquatic products such as river otters, silver fish and shrimp, as well as native products such as grass hens and ducks. In the food industry chain, the preservation process has always been a difficult problem in the industry. According to Sun Jun, the food preservation methods commonly used in the market are mainly vacuum packaging or freezing. These technologies solve the "long-term" problem of food preservation, but it is difficult to balance "freshness". Some foods cannot reach food due to fresh-keeping problems. Safety standards. Some foods are processed too fine, and frozen and chilled foods produce ice crystals during the freezing process, and nutrients are lost. The cell membrane in the food treated by the "micro-frozen preservation" technology is not frozen and cracked, and is in a state of micro-freezing of the organism, and then the food is kept fresh by refrigeration. Compared with traditional freezing, the products after “micro-frozen†can maintain their fresh quality after long-term storage and transportation.
The Lake Freshwater Aquaculture Professional Cooperative also formed a cooperative relationship with Shanghai Four Seasons Datong Company. Four Seasons Datong Company is a listed company, mainly engaged in the sales of agricultural products. Its products are sold throughout the country, covering more than 240 supermarkets in Nanjing alone. The ingredients of Four Seasons Datong Company come from “Five Lakes and Four Seasâ€, and Hongze Lake's aquatic products are one of its sources. After the cooperation, the Hongze Lake aquatic products purchased by the Four Seasons Datong Company will be directly treated in the “fresh-frozen†treatment of the Lake Freshwater Aquaculture Professional Cooperative, and then shipped to all parts of the country. This cooperation made Sun Jun’s cooperatives busy at once. Sun Jun said: "The orders of the Four Seasons Datong Company are particularly large, which directly reduced the processing volume of our cooperative products by three or four times. Our existing cold storage has not been able to meet such a large demand, and plans to invest in the expansion of the cold storage."
Nowadays, the lake fresh aquatic product breeding cooperatives have successfully exported Hongze Lake aquatic products to Japan and South Korea with the technical advantage of “micro-freezing and fresh-keepingâ€. Last year alone, cooperatives exported more than $2 million in sales and achieved sales in the domestic market of several million. For the future, Sun Jun has his own plans: "The next step, I hope to communicate with scientific research institutions in Nanjing, Huai'an and other places, actively seek new development ideas, and learn more advanced technologies and techniques in aquatic product processing. It is best to work together. Carry out scientific research activities or develop a series of products together to continuously enhance market competitiveness. At the same time, we will hire specialized technicians and professional marketing teams to further enhance the economic benefits of our cooperatives."
