Non-Thermal Sanitation By Atmospheric Pressure Plasma (Completed)

Last Published: 03/26/21 03:34:00 PM (Central)

Task Book: Entry
Principal Investigator: Remiker, Ross

Short Title: Atmospheric Pressure Plasma

Responsible HRP Element: Space Human Factors and Habitability

Collaborating Org(s):

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Solicited

Aims:

To develop and evaluate a plasma reaction chamber prototype, with an optimized power supply and jet reactor, for fresh food sanitation.
To demonstrate sanitation of up to two servings of fresh food in minutes with minimal effect on taste and texture.
To develop operational procedures to ensure safe use of the Non-Thermal Sanitation By Atmospheric Pressure Plasma (NTSAPP).
To evaluate the impact of the hardware on International Space Station resources.

Deliverables (1)

Category: Technology or Tool
Subcategory: Systems Solutions, Prototype Hardware or Software

Description:

The final deliverable is a cold plasma prototype that has the capability to reduce the microbial load on fresh produce by several logs. The technology will be further evaluated for safety, resource use, and resiliency to determine its capability to contribute to gap closure and risk mitigation by providing a safe, low resource use, waterless solution to reduce the microbial load of fresh produce grown in a bioregenerative system in space flight.
