Effect of Enrichment by Soy Isolate, Lentil Flour, Albumin and Spirulina platensis on the Quality Attributes of Industrial Noodle

In the present study, fortification of industrial noodles with lentil flour (7-35 %), soy protein isolate (SPI), albumin and Spirulina platensis microalgae were (at 1 to 5 %) and their physicochemical, rheological and sensory properties were evaluated. Treatments containing 1-5 % of S.platensis had higher ash, moisture, fat and protein content compared to treatments containing albumin, lentil flour, soy isolate content and control samples. Increasing the levels of S.platensis and lentil flour individually resulted in a decrease in the peroxide value. The lowest L * , a* and b* value were related to the treatments containing S.platensis, while the treatments containing lentil flour had the highest a * and b* and the highest a * was related to the treatments containing albumin. In all treatments, with increasing the level of all additives, the firmness increased and treatments containing SPI showed the highest firmness. However, the highest adhesion, gumminess and chewability were related to the treatments containing lentil flour and the highest gumminess and chewability were related to albumin. Different levels of albumin had the highest color scores compared to other treatments and control samples. The highest score of taste, texture and overall acceptance belonged to the treatments containing different levels (2 - 5%) of albumin. As a conclusion, it can be said that different levels of albumin had the most significant effect on the quality properties of industrial noodle samples, and in contrast, treatments containing spirulina did not show acceptable results in the quality tests evaluated.
