CMYK nutraceuticals from Algae Printing
Algae have long been a compact source of health food because of their high content of beneficial nutrients or ‘nutraceuticals’: Chlorella for its chlorophylls and carotenoids; Spirulina for its phycobiliproteins; Dunaliella for β-carotene and Haematococcus pluvialis for astaxanthin. There is an interrelation between colour and light and this is at play in these algal nutrients as their role in nature is to act as photopigments within the photosynthetic apparatus to capture a specific region of the visible spectrum thereby giving rise to a characteristic colour. The health benefits of many of these molecules comes from their anti-oxidant activities.
The development of Algae Printing opens up the possibility of ‘printing out’ health-food strains on edible paper like rice paper and create organic algal supplements for personalized consumption, with photopigments being used for functionality (nutraceuticals) as well as for aesthetic coding. Selecting a CMYK range of health-food strains, one can design personal supplementary recipes in a visual and contemporary language. In the urban environment, algae could be grown like herbs for personal consumption and so add a new dimension to modern food culture.

Algae at the intersection of social and natural ecologies
Without easy access to fish, meat or vegetables on arid land, the traditional use utilised local wild blooms of the freshwater cyanobacterium Spirulina adapted to alkalinity. From harvesting, dewatering, making of Dihé (blocks of dried cells) to selling them in their local market or using them in their family recipes, the traditional process still continue to play a socio-cultural, economic role in the tribal lives. However, in the face of climate change (Gore 2006), such traditional systems can become victim.
The farming and production of modern algal supplements are far removed from cultural or social ecologies of the consumers due to industrial manufacturing and climate-specific cultivation. Using closed culture systems, Algae Printing is a way to bring back the socio-cultural dimension by once again humanising the bioprocessing scale and method. In the context of the urban environment, digital printing serves equivalent to such social practice.
