This type of imaging can also understand information such as "fat/lean content, tenderness, freshness, pH, and more," according to P&P Optica.


By compiling data over time, the imaging tech gets smarter using machine learning and can be correlated to indicate more than what foreign material is present, but can also suggest something about production methods. This data can be tailored "on-the-fly," says the company, to get specific information for unique applications.

At a rate of 20,000 pounds of chicken in a single hour, hyperspectral imaging is a promising contender in the effort to make processing more reliable with its ability to look deeper.
