Single-cell protein (SCP) refers to protein-rich biomass derived from microorganisms like yeast, bacteria, algae, and fungi. It is used as a food source or feed supplement.
- Importance and Significance:
- Sustainability: SCP can be produced using non-arable land, using waste materials like agricultural residues, making it an eco-friendly and sustainable source of protein.
- Nutritional Value: SCP is rich in proteins, amino acids, vitamins, and minerals, making it a valuable nutritional supplement.
- Alternative Protein Source: It can be used to address protein malnutrition in areas where traditional animal-based protein is scarce or expensive.
- Animal Feed: SCP is used as animal feed, especially in aquaculture and poultry industries, offering a cost-effective and high-protein alternative to traditional feeds.
- Human Food: SCP can be processed into food ingredients like protein powders, meat substitutes, or nutritional supplements. It is particularly important in regions where food security is a concern and can provide a sustainable source of protein for humans.
SCP’s production process typically involves growing microorganisms on organic substrates like methane, glucose, or waste materials, followed by harvesting and processing to make the protein suitable for consumption. It serves as a potential solution to address food shortages and provide high-quality protein to meet the growing demand.
