Potential of Chlorella Growth Factor (CGF) in Food and Feed Applications


Recently, scientists at CSIR-Indian Institute of Chemical Technology (IICT) have spotlighted the potential of Chlorella Growth Factor (CGF), a protein-rich extract derived from the microalgae ‘Chlorella sorokiniana’, as an ideal ingredient for a wide range of food and feed applications.


Facts for Prelims

What are Chlorella Growth Factor (CGF) and Chlorella Sorokiniana?

Chlorella Growth Factor (CGF):
  • Rich in Nutrients: CGF is abundant in high-quality amino acids and proteins, making it a promising alternative for both human and animal nutrition.
  • Essential Components: Contains vital amino acids and nutrients such as peptides, nucleotides, polysaccharides, vitamins, and minerals, surpassing commercial soy meal.
  • Extraction Process: Obtained through a non-chemical autolysis method, preserving the integrity of amino acids and other valuable elements.
  • Benefits to Animal Feed: Enhances egg quality when added to chicken feed, indicating its potential as a superior protein supplement for animals.
  • Sustainable Crop: Microalgae like Chlorella sorokiniana are viewed as “under-exploited crops,” not competing with traditional food crops for resources, thus offering a sustainable solution for meeting the growing global demand for high-quality protein.
Chlorella Sorokiniana:
  • Unique Characteristics: This oval-shaped, single-celled algae stands out in the microscopic world due to its active growth capability.
  • Self-Contained Organism: Each cell is a complete organism, containing all the essential nutrients required for life, making it self-sustaining.
  • Rapid Reproduction: Can multiply rapidly, expanding from one cell to 24 cells within 24 hours when exposed to sufficient sunlight and nutrients.
