Description:
The data was collected from frozen-thawed, minced meat samples (pork, beef, chicken, lamb and mixtures of 2-50% pork with the respective other meat) using five NIR sensors in reflection and not precessed any further.
Description of the sampling procedure, processing of the samples as well as measurement settings are according to Mueller-Maatsch et al. (2021, https://doi.org/10.5445/KSP/1000128686) .
