AB  - The aim of this study was to compare the sensory quality and acceptance of dried ready-to-eat beetroot snacks as a result of different drying methods applied: supercritical CO2-drying (scCO(2)-drying), frying, and freeze-drying. Descriptive sensory analysis, quality rating (10 assessors), and consumer acceptance testing (n= 102) were performed. Mean overall quality scores within the range of "very good" quality were found only in non-precooked scCO(2)-dried samples which were characterized by typical magenta color, low level of shape and surface deformations, pronounced brittleness and crispiness, and good rehydration during mastication. The other samples were in the range of "good" quality. The pre-cooking step before scCO(2)-drying negatively influenced the sensory quality parameters, particularly appearance. Around 60% of tested consumers showed a preference for the fried and non-precooked scCO(2)-dried samples. The drivers of liking were mostly related to the characteristics of the product, which was salted, fried, and crispy, with an oily and overburnt flavor, i.e., the product most similar to commercial potato chips products. Freeze-drying had a negative effect primarily on appearance and flavor. According to the sensory evaluation conducted, direct scCO(2)-drying without a pre-cooking step showed itself as a promising alternative drying technology in the production of dried beetroot snacks.

AB  - The aim of this study was to analyze the stability of sensory properties and secondary metabolites in supercritical-CO2 (scCO(2)) dried 'Elstar' apple cuts/snacks during twelve months of storage at 'room' temperature. Air-drying and freeze-drying were used as reference methods. ScCO2-dried apple packed in aluminum-polyethylene bags under nitrogen gas retained a high sensory and nutritional quality, and acceptance level until the end of the observed period. The overall acceptance scores of these apples after 6 and 12 months of storage remained in the range of neutral consumer attitude "neither like nor dislike". Packaging under nitrogen gas preserved the content of flavonols ( >= 0.14 g/kg), dihydrochalcones ( >= 0.10 g/kg), hydroxycinnamic acids ( >= 0.18 g/kg), triterpenes ( >= 5.72 g/kg), and proanthocyanidins ( >= 0.08 g/kg) in dried apple irrespective of the drying method applied. The comparison with the conventional drying processes demonstrated that scCO(2)-drying represents a promising alternative technology for the production of dried apple snacks. The study was assisted by the evaluation of consumer attitudes towards dried fruit and drying technologies. Freeze-drying, air-drying and scCO(2)-drying were recognized by the tested consumers as trustful drying-processes, with expressed interests in buying scCO(2)-dried products if the technology was scientifically proven as excellent in preserving nutrients, color and taste of food products.
