Hi all,

 

I have a question please, is there any kind of "Testing kit" that can help us determine if raw chicken were previously frozen?

My understanding from a client's lab is that you would need a "density" analysis and no, I have no idea how this works.


Kind regards,

I think the only way to detect previously frozen meat is under a microscope as the cell structure will have changed.

How about water activity? Wouldn't it be different in thawed and fresh chicken? Logically, it should be, no?

Thanks for replying. 

A chicken company (client) is asking if there is any testing that can help them identify the raw material they use, it is a good direction to check with labs maybe.

That's an idea! I will try to find if there is any literature published one this topic.

Thanks!

I am not sure, maybe there is something out there about this.

I will try to look around. Thanks :)
