I​n Singapore, to enhance food security, the “30 by 30” goal calls for an increase in capability and capacity to grow 30 per cent of total food needs locally and sustainably by 2030. In the land-scarce city state, meeting this goal through traditional food and protein production methods alone will be challenging.

The “Urban Microalgae-Based Protein Production” project sets out to establish a resilient and sustainable agri-food platform for microalgae-based food products. Taking a whole value-chain approach, the project combines emerging microalgae concepts with technological and process innovation, with a goal of developing a tangible food product concept.

While meat and seafood are viable sources of protein, the resource-intensive nature of their production continues to put a strain on the environment. In recent years, meat and seafood alternatives have become more available. However, the commonly used key ingredients of soy or wheat come with significant needs for arable land. 

Microalgae, on the other hand, have a very low demand for land, among other advantages. From the perspective of nutrition, microalgae-based food products are good sources of protein and vitamins, with well-balanced amino acid profiles and good ratios of polyunsaturated fatty acids. What is needed to make microalgae-based protein more commercially viable are innovative processes to improve the supply-chain eco-efficiency, as well as an R&D platform for food concept development. 

Novel Proteins for Food and Feed project

This whole-value chain approach brings together expertise from the Novel Proteins for Food and Feed project at the Swiss Federal Institute of Technology (ETH) Zurich’s World Food Systems Centre, as well as the Department of Food Science and Technology at the National University of Singapore (NUS) and the Singapore Institute of Food and Biotechnology Innovation at Agency for Science Technology and Research (A*STAR).

Ultimately, consumer acceptance of the microalgae-​based food concept depends on whether the cost, nutrition, taste, texture, and smell are sufficiently tailored to the preferences of the local market. For those reasons the team is taking a reverse engineering approach, and co-​creating food concepts by incorporating consumer insights as well as collaborating with relevant partners.

The partners include Swiss and Singapore-​based food producers Nestlé and ingredient processing companies including Bühler, Givaudan, Planted Foods, and Sophie’s Bionutrients. Additionally, the Singapore Food Agency is playing advisory role and providing feedback on the project’s R&D direction and decisions.

  • July 19, 2024: A three-year development effort, the Ethiopian Bio and Emerging Technology Institute — in collaboration with the Ministry of Innovation and Technology and the Oromia Agricultural Research Institute — has recently launched the nation’s first microalgae (spirulina) research and production center at the Adami Tulu Agriculture Center, from an investment of 8.2 million birr ($142,600 USD).

  • July 17, 2024: A study from the University of New Hampshire has found that integrating farmed shrimp with oysters and seaweed in integrated multi-trophic aquaculture (IMTA) systems significantly reduces nitrogen levels. This could make shrimp farming more responsible and potentially support the growth of the U.S. industry. READ MORE...
  • July 15, 2024: Atlantic Sea Farms, a Maine-based leader in farmed seaweed, has harvested a record-breaking 1.3 million pounds of farmed seaweed in the 2024 harvest season. The company, which partners with fishing families to farm kelp in Maine, Rhode Island, and Alaska, has expanded both the supply of domestic line-grown kelp, as well as the market for their traceable, regeneratively farmed products to American consumers, chefs, and CPG companies since 2019.

  • July 12, 2024: Researchers have created tiny, vehicle-like structures which can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming. Two types of vehicles were created: the “rotator,” which spins like a wheel, and the “scooter,” which was intended to move in a forward direction but in tests moved more surprisingly. READ MORE...
