Laboratory Equipment to Test the Freshness of Shrimp

Dear All,

 

I am a QA Specialist in a meat processing company, in which we are engaged in marinated proteins - chicken, beef and seafood products. I would like to acquire a laboratory equipment which is capable to check the freshness of the shrimps - to determine if the shrimp delivered to our factory is young or old, which will be a Quality basis in acceptance or rejection of the incoming raw materials. 

 

Appreciate any feedback or anyone who has an idea about this Quality parameter?

 

Thanks in advance for your replies.

Hi Chris,

 

Many attempts over the years have been made to devise a routine, commercial instrument such as you mention for measuring "seafood" freshness. afaik without general success.

 

One current area of research effort seems to be involving e-nose, eg -

How about meat ?

Hi charles,

Thanks for this valuable information. We are actually having some problems with our shrimp products as customer complaints are coming in due to the presence of ammonia odor and after-taste, which appears after cooking the shrimp in our restaurant. I made some research and learned that this "chemical" taste signifies that the shrimps that were cooked are already old, and is impossible to detect during the processing stage. This is the main reason why I came to the idea of acquiring an instrument for freshness.

For our meat products such as chicken and beef we are actually importing them and we never had any issues on Quality for these products.

Thanks again for this info 😊

Chris
