Aims:
  1. To formulate nutrient requirements for meal replacement beverages and bars along with guidelines for consumption.
  2. To develop beverage(s)  meeting nutrition, sensory, and shelf life requirements for space food system.
  3. To develop bar(s)  meeting nutrition, sensory, and shelf life requirements for space food system.
  4. To demonstrate reduced upmass of the food system and reduced trash volume by incorporation of the beverages and bars.

The final deliverable was a report that contributed to gap closure by informing the capabilities and limitations of producing macronutritionally balanced meal replacement options that are both acceptable and provide a savings in mass, volume and crew time over a traditional breakfast or lunch meal. The meal replacement bar prototypes nearly doubled caloric density, and bar and beverage options demonstrated shelf stability ranging from 48-96 weeks. Menus that include meal replacements were generated based on the ISS 10-day standard menu, and mass savings ranged from 11-25% when one meal was replaced each day. Packaging savings ranged from 16-18% when one meal was replaced each day. Further development and acceptability testing will determine the extent that these products can be implemented into the food system and the resulting total mass savings.
