Abstract

The gummy industry is showing a growing interest in adding novel ingredients to conventional formulations since consumers are looking for healthier and more nutritious products. Thus, this work aimed to develop sucrose-free gummy candies without artificial food dyes and incorporated with Spirulina biomass and freeze-dried açai pulp (FDAP) at concentrations of 1%, 3%, and 5%. Gummy candy enriched with 5% Spirulina (GSP5) showed the nutritional (increase of 36.7% and 414.3% in protein and mineral contents, respectively) and functional increments (0.081 mg GAE g−1 of phenolic compounds and 11.4% DPPH scavenging activity) when compared to control (GC; 0% Spirulina). Gummy candy added with 3% FDAP (GAC3) showed 1.7% lipids, 0.4% minerals, 0.190 mg GAE g−1 of phenolic compounds, and 27.0% DPPH scavenging activity. The acceptability index was satisfactory for both formulations GSP5 (78.7%) and GAC3 (83.8%). Therefore, Spirulina biomass and FDAP could be used as innovative ingredients in sucrose-free gummies manufacturing.

Novelty impact statement

The addition of Spirulina biomass and freeze-dried açai pulp in gummy candies improved their nutritional and functional value. Spirulina biomass addition increased gummy candies protein and mineral content, whereas gummy candies enriched with freeze-dried açai pulp exhibited antioxidant capacity up to 36% and the highest phenolic content. Besides, the sensory evaluation of gummy candies indicated a high acceptability index of around 80%.
