[Microalgae Spirulina in human nutrition]

Area of Science:

• Nutritional Science
• Phycology
• Biotechnology

Context:

• Spirulina microalgae (Spirulina platensis, Spirulina maxima, Spirulina fusiformis) is recognized for its nutritional value, providing high-quality protein, essential fatty acids, vitamins, and minerals.
• Despite compositional variability in open reservoirs, Spirulina demonstrates efficacy in disease treatment and prophylaxis through experimental and clinical studies.
• Cultivation methods, particularly in closed photobioreactors, allow for enrichment of Spirulina biomass with bioavailable trace elements.

Purpose:

• To highlight Spirulina's nutritional profile and therapeutic potential.
• To explore the enrichment of Spirulina biomass with essential trace elements.
• To position Spirulina biomass as a key component in novel bioactive food supplements.

Summary:

• Spirulina microalgae is a nutrient-dense food source, rich in protein, iron, gamma-linolenic acid, carotenoids, and B vitamins.
• Clinical and experimental evidence supports Spirulina's role in the treatment and prevention of various diseases.
• Cultivation, especially in photobioreactors, enhances Spirulina with bioavailable trace elements like iron, iodine, and selenium.

Impact:

• Spirulina serves as a valuable supplementary food and a potential therapeutic agent.
• Enriched Spirulina biomass represents a promising ingredient for developing new bioactive food supplements.
• This research underscores the potential of microalgae in functional foods and nutraceuticals.
