Information about fortified pasta with <em>S. platensis</em> microalgae is very low. <em>S. platensis</em> microalgae powder at a level (% W/W), 0.0, 0.25, 0.5, 0.75 and 1 %, was added in pasta formulation. Protein, iron, microbial and sensory properties of product were analyzed. Microbiological testing of the samples, was conducted according to the national standard methods. Sensory evaluation was conducted by 60 panelists using hedonic method. The results showed that different levels of microalgae <em>S. platensis</em> powder had a significant effects on chemical parameters of pasta (<em>p</em><0.05). Also&nbsp;interaction of microalgae powder on microbial features of pasta was not significant (<em>p</em>>0.05). Sensory evaluation test indicated greater acceptability of pasta fortified with microalgae<em> S. platensis</em> powder at a concentration of 0.25%, as compared to the control sample. With the addition of 0.25% of <em>S. platensis</em> microalgae powder to pasta formulation, while reaching enriched product, nutritional value and sensory characteristics of pasta heals and a functional food will be available to the community.
