SPIRULINA: A SPOTLIGHT ON ITS NUTRACEUTICAL PROPERTIES AND FOOD PROCESSING APPLICATIONS

Abstract

Spirulina, blue-green algae is now worldwide used as a dietary supplement owing to its richness in protein (50-60%), antioxidants, essential fatty acids, etc. The amino acid composition of Spirulina protein ranks among the best in the plant world, more than that of soya beans.  This review article serves as an overview of why Spirulina is considered as a ‘superfood’. Its methodologies of cultivation, richness in nutrients and bioactive components, therapeutic properties in the health food circuits, and versatile utilization in various food supplements are elaborately introduced. All possible fortification of Spirulina platensis emphasizing the elevation of nutrient levels in bakery products, beverages, dairy products, extruded snacks, energy bars, infant foods, and confectionaries is briefed. Beyond, these algae convert carbon dioxide into organic substances and produce oxygen during their growth in alkaline and saline water thereby not wasting fresh water and allowing the production in barren areas. Such an organism with a plethora of health profits to humans, animals and the environment is limitless and has probably more to offer in the future.
