The global Single Cell Protein Industry is set for significant growth in the coming years, driven by increasing awareness of sustainable protein sources, rising demand for alternative food and feed ingredients, and advancements in biotechnological innovations. The shift toward environmentally friendly protein production is accelerating the adoption of SCP across various industries, including food, animal feed, and biofuel production.

Market Definition and Scope

Single-cell protein refers to microbial biomass or extracted proteins derived from microorganisms such as algae, fungi, bacteria, and yeast. These proteins serve as an alternative to traditional protein sources and are utilized in human nutrition, animal feed, and industrial applications. SCP is gaining popularity due to its high protein content, rapid production rate, and minimal land and water requirements, making it a viable solution for addressing global food security challenges.
