Hypothesis
The study aims to evaluate the nutrient stability of the Nutrient-upgraded Rodent Food Bar (NuRFB) under different storage conditions over time.
Conclusion
The study confirms that NuRFBs maintain stable vitamin and lipid oxidation indices, ensuring adequate nutrition for rodents during spaceflight.
Supporting Evidence
- Vitamin D levels showed a minor decrease, but all vitamin levels remained above National Research Council minimum requirements.
- Food bars stored at 4 °C showed significantly higher thiamine levels than those stored at ambient temperatures.
- Minimal lipid oxidation was observed for up to 18 months, and no mold or yeast growth occurred.
Takeaway
This study shows that the food bars for mice in space stay nutritious for a long time, even when stored at room temperature.
Methodology
The study analyzed the nutrient levels and lipid oxidation of NuRFBs stored under various conditions over a period of 27 months.
Limitations
The small sample size of n = 1 limits the ability to draw definitive conclusions.
