The study explored using visible and near infrared reflectance spectroscopy (NIRS) to detect fish meal adulteration with soybean meal.
Various proportions of soybean meal were added to fish meal to create test samples, with a focus on developing reliable qualitative and quantitative analysis models.
The best results showed a 96.12% correct identification rate of the adulterated samples, confirming the method's effectiveness with high R² values in quantitative assessments.
