Summary

The natural colour pigment phycoerythrin is highly sought after by the plant-based meat industry as it is an analogue to haeme found in red meat. This project will investigate the production of phycoerythrin from sustainably cultivated native red seaweeds in at-sea or land-based cultivation systems. Initial investigations will include the development of a reliable analytical technique to quantify the pigment in red seaweed and the screening of native red seaweeds to identify taxa with a high yield of the pigment. Once suitable seaweeds have been identified investigation into production will occur, including the development of process conditions to promote production of phycoerythrin in cultivated seaweeds. The processing requirements will also be investigated with the development a proof-of concept scale process for extraction, purification, concentration, and stabilisation of the pigment extract.

Objective Summary

Undertake a comprehensive review of published literature on extraction and purification technologies for phycoerythrin from red marine seaweeds.
Develop a sensitive, reliable and high-throughput analytical technique for quantification of phycoerythrin from red marine seaweeds.
Identify native red seaweed taxa with a high yield of phycoerythrin.
Develop at-sea and or land-based cultivation systems and process conditions to enhance phycoerythrin production in cultivated seaweed biomass.
Develop and optimise a proof-of-concept pilot scale extraction, purification, concentration, and product stabilisation process.
Develop prototype product for industry trials and evaluation.
