Task Development of Spaceflight Foods with High Microbial Concentrations (Completed)
Last Published:  07/29/22 01:33:24 PM (Central)
Short Title: High Micro Foods
Responsible HRP Element: Space Human Factors and Habitability
Collaborating Org(s):
Space Human Factors Habitability (SHFH) Element
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):
  1. To assess the current uses of live cultures in shelf stable foods
  2. To compare levels of microbial load in these foods/supplements to current requirements and assess additional risk, if necessary.
  3. To assess expected microbial load from bioregenerative produce and developed cleaning procedures.
  4. To investigate current literature and commercial operations to provide guidance in establishing microbiological requirements and testing methods for foods with high and diversified microbial concentrations.

All aims have been achieved.  The findings are documented in a final report that was issued in August of 2011.  The evidence contained in the report demonstrates a need for further research to determine the procedures necessary for growing and processing regenerative produce and development of specific cleaning methods to mitigate microbiological risks.  The report also provides a comprehensive list of potential probiotic products, which should be evaluated to determine preferred probiotic formulations for spaceflight, and notes that research should also be conducted to determine the specific microbial testing procedures for those formulations and to assess the risk of adding the formulation to the food system.
