    Abstract:
    BACKGROUND: Spirulina microalgae have been added to food; however, there have been few reports on the methods used to protect the antioxidant potential against process conditions, and the effects on the sensory characteristics of products need to be better described. The aim of this study was to evaluate the influence on the technological properties, sensory profile, and acceptability of the pasta with free or microencapsulated Spirulina biomass added. Pasta formulations included: free Spirulina (FSP), microencapsulated Spirulina (MSP), and empty microspheres (EMP), which were compared with the control pasta (CP). RESULTS: The microencapsulation protected the antioxidant potential of Spirulina in 37.8% of the pasta cooking conditions. The microspheres presented low solubility in water (86 g.kg-1 ) and high encapsulation efficiency (87.6%), this being appropriate for addition to products that need cooking in water. The technological properties of pasta (water absorption, weight gain, firmness, and adhesiveness) were affected, but the overall acceptability index (85.13%) was not influenced by the addition of microspheres, despite changes observed in the sensory profile obtained by the CATA (check-all-that-apply). CONCLUSIONS: Spirulina could be added to pasta even without microencapsulation but the microencapsulation in alginate allows for the protection of the antioxidant potential of the biomass, representing a potential alternative for the bakery industry. © 2019 Society of Chemical Industry.
