Hypothesis
The study aims to assess the reliability of a low-cost dispersive NIR spectrophotometer for quantifying moisture in commercial milk powder.
Conclusion
The study found that the low-cost NIR spectrophotometer can accurately determine moisture content in milk powder, making it suitable for use in the dairy industry.
Supporting Evidence
- The calibration model developed showed a high correlation coefficient of R2 = 0.9942.
- The NIR predicted moisture values were very close to those obtained from Karl Fischer titration.
- The study used 45 samples with moisture content ranging from 4-10% for analysis.
Takeaway
This study shows that a special light tool can help check how much water is in milk powder, which is important for keeping it fresh and tasty.
Methodology
The study used near infrared diffuse reflectance spectroscopy and Karl Fischer titration to analyze moisture content in milk powder samples.
