Beta Coefficient Interpretation for Soybean Seed and powder

Mon, 04/18/2022 - 08:58

So, I have been taking data using NIR Hyperspectral Imaging for predicting protein on soybean seed and powder, but the problem is why my beta coefficient result for soybean seeds and soybean powder is different although I used the same sample? First I took captured the soybean seed samples then I grind the seed into powder and also capture it. Please help me if you guys know the answer or if you have any theory references that could explain that phenomenon.

Thank you

Hello Aulia,

Apologies for the confusion, but this forum is for spectroscopic observing and analysis of variable stars. No one here is likely to have the expertise to help you, but good luck with your interesting-sounding project.

Best regards,

Are you doing FT-NIR in cm-1…

Sara is correct, you may be barking up the wrong tree.

Still, I may be able to help.

Are you doing FT-NIR in cm-1? Or just plain old NIR spectrophotometry in nm? Is it reflection hyper spectral imaging with a handheld unit?

I can be of more use if you present the name and model number of your instrument.

Sounds like contamination during the grinding process.

You can contact me directly via this forum.
