Terpene Extraction

Terpene Extraction

A commercial investigation studying the extraction of terpenes from wood samples. Upon activation by a crewmember, dry wood samples interact with 6 mL of a 50/50 water and ethanol solution. The MixStix are then stowed until returning to earth where the samples are analyzed by the customer, Ardbeg.

Description

NanoRacks-Terpene Extraction in Microgravity (NanoRacks-Terpene) is a commercial investigation studying the extraction of terpenes from wood samples. Dry wood samples are placed in one end of the MixStix. Upon activation by a crewmember, the wood sample interacts with 6 mL of a 50/50 water and ethanol solution. The MixStix are then stowed until returning to earth where the samples are analyzed.

Space Applications

One of the key questions for space station utilization remains a) whether the unique environment of space can capture the interest of mainstream consumer companies; and b) whether by fostering greater understanding of complex molecules, researchers can shed light on the impact of gravity on basic materials.

Earth Applications

The company undertaking the research belongs to a multi-billion dollar consumer company which produces dozens of new products that contain terpenes and other compounds each year. These include beverages, perfumes and cosmetics. Synthetic variations of terpenes and terpenoids also greatly expand the variety of flavors used in food additives.

Another application is that the ingredients of terpenes have been shown to serve as natural agricultural pesticides. Hence, the understanding of terpenes extracted without gravity may well produce new understandings of a wide range of new products and processes. This is expected to be the first of several phases of research, all sponsored by the company.

Operational Requirements

The experiment is activated by flexing the liquid mixing containers. The experiment is then re-stowed until ready to return on 30S.

Operational Protocols

A crewmember removes the Velcro tabs to open the Module-9 lid. A MixStix is removed and the crewmember flexes it to break the internal reservoir and release the liquids (flex down the entire length of tube). The crewmember then shakes the MixStix to mix the liquids thoroughly. Repeat for all 24 MixStix. Crewmember notes the time of MixStix activation and replaces the tubes back in Module-9. The lid is replaced and secured with the Velcro tabs.
