Abstract

Edible gels are a promising form of functional food suitable for seniors, who often face difficulties with swallowing and insufficient nutrient intake. Their structure allows for the incorporation of bioactive compounds with good gastrointestinal absorption and subsequent health benefits. The aim of this study was to evaluate the sensory acceptability of prototypes of edible gels enriched with bioactive substances and to propose recipe optimisation. Curcumin, known for its antioxidant and anti-inflammatory effects, was selected as the model bioactive compound. The gel matrices were prepared using two polysaccharides, arabinogalactan or beta-glucan and two flavours (apple pulp or vanilla). Each variant was produced in two versions, without bioactive substances or with added curcumin resulting in eight samples. The samples were stored at 4 °C and equilibrated to room temperature for 2 hours before evaluation. Eighty senior participants (40 in Slovakia, 40 in the Czech Republic) aged 65 and over took part in the sensory evaluation, assessing anonymised samples presented in random order. The evaluation was conducted in accordance with ISO 8589:2007 guidelines, using descriptive analysis with a 9-point hedonic scale (1 = very poor, 9 = very good). The results showed that edible gels represent a promising platform for the application of geroprotective agents for seniors. Arabinogalactan in combination with fruit flavours proved to be the best accepted matrix, while beta-glucan and curcumin require technological interventions to improve the sensory profile. From a practical point of view, these results are relevant for the development of new functional foods intended for the aging population.
