It is a good idea to preserve seafood with dry ice pellets or dry ice blocks. In the summer, seafood is not easy to store and is prone to odor. But seafood is one of the most popular high-end foods in the summer, so in order to eat fresh seafood, people have tried all kinds of ways to preserve seafood, such as using ice cubes.
Hata hivyo, wakati wa majira ya joto ni moto, njia hizi za kuhifadhi dagaa hazifanyi kazi vizuri sana. Hivi majuzi, nilipokuwa nikila dagaa wakavu wa barafu kwenye hoteli, nilijifunza njia nzuri ya kuhifadhi dagaa kwa kutumia barafu kavu ya kaboni dioksidi. Nilijaribu mwenyewe na kuweka dagaa kwa muda mrefu. Inafaa kupendekeza.
How to preserve live seafood with solid dry ice blocks or dry ice pellets?
Seafood should be kept in a ventilated foam incubator, and the seafood and dry ice should be stored in a stack. First, put a layer of dry ice granules or dry ice blocks in a foam box, then lay a layer of hay on the dry ice, or well-breathed cotton or sponge, then place the crab and other seafood on it. The dry ice and crabs should be in a layered manner to keep the seafood alive for a long time.
The preservation of seafood requires a suitable temperature. Preserving live seafood must give seafood products a comfortable environment. Only when the temperature is right, the seafood will not die very quickly, too cold or too hot will be not good. Usually, the temperature is determined according to the characteristics of each kind of seafood. Therefore, dry ice products and live seafood cannot be directly contacted, because the dry ice temperature is extremely low, and the seafood will be frozen to death.
Why dry ice blocks can be used to preserve seafood?
Sababu kwa nini barafu kavu inaweza kuhifadhi dagaa wapya ni kwamba halijoto yake ni ya chini sana, inaweza kufikia digrii minus 78, na ni safi kimazingira, haina uchafuzi wa mazingira, na inafaa kwa usafirishaji na matumizi. Mbali na hilo, barafu kali kavu inaweza kubadilika kuwa gesi ya kaboni dioksidi, ambayo ina kazi ya kuzuia oksijeni na kuzuia kutu.
Gesi ya kaboni dioksidi ina mvuto maalum zaidi kuliko hewa, na inaweza kufunika uso wa dagaa, kucheza kizuizi cha oksijeni, kupunguza kiwango cha oxidation ya dagaa, na kuzuia ukuaji na uzazi wa bakteria, ambayo ni faida ya kipekee ya barafu kavu uhifadhi wa chakula na dagaa.
