|NASA Research Announcement
- To compare two methods to measure food acceptability/quality in microgravity. The current standard, of using a 9-point hedonic scale for overall acceptability, will be compared to the Labeled Affective Magnitude (LAM) scale to determine which method provides more accurate data for use in future reformulations for NASA food items.
- To learn how effects observed in spaceflight are related to those observed in ground-based tests.
- To learn how affective scale type (LAM or Hedonic) affects the quality of affective data output.
The LAM scale has been shown to allow greater discrimination of highly preferred items and have greater correlation with product usage.
The proposed testing would primarily utilize the prepackaged food system that is already provided on orbit. Test ballots can be provided in paper or electronic form. No additional mass or volume to conduct this study.
Prior to the flight testing, sensory data conducted to-date on the Astronaut population will be gathered. Additional ground sensory evaluation testing will be conducted with the astronaut population using the LAM scale.
