Spirulina production and processing refers to the cultivation, harvesting, drying, and conversion of spirulina biomass into value-added products such as spirulina powder, tablets, capsules, flakes, extracts, and fortified food ingredients. Spirulina is a blue-green microalgae (Arthrospira platensis) widely recognized as a superfood due to its exceptionally high protein content, essential amino acids, vitamins, minerals, antioxidants, and bioactive compounds. It is extensively used in nutraceuticals, functional foods, pharmaceuticals, cosmetics, animal feed, and health supplements.
Spirulina contains over 60-70% protein, along with phycocyanin, chlorophyll, iron, calcium, beta-carotene, and essential fatty acids. Due to its nutrient density and digestibility, spirulina is widely consumed as a dietary supplement for immunity enhancement, detoxification, weight management, sports nutrition, and malnutrition control. It is also used in fortified foods, beverages, cosmetic formulations, aquaculture feed, and poultry feed.
Spirulina production is primarily carried out using controlled cultivation systems such as open raceway ponds or closed photobioreactor systems. The manufacturing process involves culture preparation, controlled algae growth, harvesting through filtration or centrifugation, washing, drying at low temperatures, pulverization, and hygienic packaging. Advanced technologies such as paddle wheel raceway ponds, tubular photobioreactors, spray drying, freeze drying, and tablet compression systems are used to ensure high purity, nutrient retention, and consistent quality. Strict monitoring of pH, temperature, light intensity, and contamination is essential throughout the process.
India has emerged as a significant producer of spirulina due to favorable climatic conditions, low production cost, skilled manpower, and increasing demand from domestic nutraceutical and export markets. Government initiatives promoting nutrition, wellness, and alternative protein sources have further supported the growth of spirulina production units across the country.
