Deca-triticale

Deca-triticale was a nutrient used by Space Pirates in the Phazon Mines operation. Deca-triticale was utilized in the Elite Nutrient Mix prepared for the Project Helix Elite Pirate test subjects. It would later be replaced with Phazon-corrupted Saturnine matter, which was viewed by the Pirates as a cheaper and more plentiful resource.

Trivia

 * In the real world, triticale is a grain hybrid of wheat and rye. Judging by the name, deca-triticale should have ten lobes per kernel. Why the Space Pirates would be using a human food in their experiments is unknown.
