| Summary: | History aside, traditional mayonnaise faces a rising animal welfare concern dietary approach and remains dependent on cold environments throughout the supply chain due to food safety. Nowadays, consumers are able to find alternative formulas from vegetable sources with relevant emulsifying capacity. However, sensory characteristics may differ from the traditional expected product. A mixed system composed of the innovative ingredient heterotrophic white <i>Chlorella vulgaris</i> and a disruptive emulsifier, yeast protein extract (YPE), was assessed to transform traditional coriander mayonnaise into an analog product. The effect of pH and salt (NaCl) content was also evaluated. The mixed system depicts a promising stability since the average Sauter diameter of both is similar (7.94 μm and 7.49 μm), also observed in the unimodal droplet size distribution. Viscoelastic behavior has slightly different responses for the plateau model (278.951 Pa and 252.053 Pa), while increasing the salt content reflects an approximation regarding firmness (0.059 N and 0.057 N) and adhesiveness (0.372 N.s and 0.361 N.s). Introduction of microalgae increases bioactivity, mainly TPC (+118.84 ugGAeq/g) and antioxidant activity—RSA (+31.29 ugTEAC/g) and FRAP (+35.26 ugTEAC/g). Despite the color deviation, the sensorial analysis of both products enlightened the absence of major perception. |
