Summary
Near-infrared (NIR) spectrophotometry accurately analyzes human milk
Area of Science:
- Nutritional Science
- Analytical Chemistry
- Biomedical Engineering
Background:
- Accurate human milk analysis is crucial for neonate nutrition.
- Current methods can be time-consuming.
- Near-infrared (NIR) spectrophotometry offers a rapid alternative.
Purpose of the Study:
- To validate the accuracy of NIR spectrophotometry for real-time analysis of human milk macronutrients (carbohydrate, fat, protein).
- To assess the feasibility of NIR for optimizing nutrient intake in high-risk neonates.
Main Methods:
- A prospective study involving 52 human milk samples.
- Analysis using the SpectraStar 2400 Near Infrared Analyzer.
- Calibration and validation against primary chemical analysis for fat, protein, and carbohydrate content.
Main Results:
- High correlation coefficients were achieved: 0.91 for carbohydrates, 0.95 for fat, and 0.95 for protein.
- Logistic regression analysis confirmed the accuracy of the NIR method.
- The validation set demonstrated strong predictive power.
Conclusions:
- NIR spectrophotometry is a feasible and accurate method for real-time human milk nutrient analysis.
- NIR technology holds potential for adjustable fortification of human milk.
- Optimizing nutrient intake for high-risk neonates can be enhanced through NIR analysis.
