as a delicious seafood, abalone is loved by consumers for its unique taste and nutritional value. however, due to the high water content of abalone, it is prone to spoilage and mechanical damage during storage and transportation. in order to solve this problem, many manufacturers use liquid nitrogen quick-freezing technology to preserve abalone to maintain its taste and quality. this article will introduce the application and advantages of liquid nitrogen quick freezing technology in abalone preservation.

abalone preservation problems

abalone has a high water content, which makes it susceptible to microbial contamination and mechanical damage, which accelerates spoilage. traditional preservation methods are difficult to solve this problem, so liquid nitrogen quick freezing technology has become an important solution.

principle of liquid nitrogen quick freezing technology

liquid nitrogen quick-freezing technology uses the low-temperature properties of liquid nitrogen to quickly expose abalone to extremely low temperatures. the temperature of liquid nitrogen can reach minus 196 degrees celsius, which can quickly freeze abalone and inhibit the growth of microorganisms and enzyme activity.

this helps maintain the freshness, taste and nutritional value of the abalone.

advantages of liquid nitrogen quick freezing technology

maintaining quality: liquid nitrogen quick-freezing technology can quickly reduce the temperature of abalone to extremely low levels, reducing the risk of spoilage and maintaining the freshness and taste of abalone.

inhibit the growth of microorganisms: liquid nitrogen at extremely low temperatures can effectively inhibit the growth of bacteria and mold and extend the shelf life of abalone.

reduce mechanical damage: liquid nitrogen quick freezing technology can not only freeze abalone, but also form a protective ice layer to reduce mechanical damage during transportation and storage.

the importance of thawing correctly

although liquid nitrogen quick-freezing technology can maintain the taste and nutritional value of abalone, the thawing process is equally important. proper thawing methods can preserve the quality of abalone to the greatest extent. it is recommended to use the gradual thawing method.

for example, place abalone in the refrigerator to defrost slowly to avoid adverse effects on the taste caused by rapid temperature changes.

liquid nitrogen quick-freezing technology plays an important role in abalone preservation. it can effectively maintain the taste and quality of abalone. for consumers, liquid nitrogen quick-frozen abalone provides a fresh, delicious and convenient option.

however, when purchasing and cooking abalone, proper thawing method is equally important to ensure the best eating experience. liquid nitrogen quick-freezing technology will continue to play an important role in the seafood industry and meet people's demand for high-quality seafood products.
