| Summary: | [Display omitted]
•Higher total phenolic compounds values can be achieved when the processing time was longer (>8 min) and lower power intensity (<80 W) were applied.•Elevated values of total carotenoids can be obtained when the processing time was longer (>10 min) and power intensity was lower (<150 W) or when the time was shorter (<2 min) and power intensity was higher (>350 W).•Rheology demonstrates that the extracts were considered pseudoplastic, with assay 4 tending toward Newtonian behavior.•The conditions that would best provide the desired responses are: low power and short duration, as well as low power and extended duration.
The use of extracts rich in bioactive compounds is becoming increasingly common in the food, cosmetics, and pharmaceutical industries for the production of functional products. Araticum is a potential fruit to be analyzed due to its content of phenolic compounds, carotenoids and vitamins, with antioxidant properties. Therefore, this study aimed to investigate the effect of ultrasound on total phenolic compounds, total carotenoids, ascorbic acid, color, turbidity and rheology in araticum juice. Response surface methodology based on a central composite design was applied. Araticum juice was subjected to sonication at amplitude levels ranging from 20 to 100 % of the total power (400 W) at a constant frequency of 20 kHz for different durations (2 to 10 min). Morphological analysis was conducted to observe microscopic particles, and viscosity and suitability to rheological models (Newtonian, Power Law, and Herschel-Bulkley) were assessed. The ultrasonic probe extraction method was compared to the control juice. According to the responses, using the desirability function, the optimal conditions for extraction were determined to be low power (low amplitude) applied in a short period of time or low power applied in a prolonged time. These conditions allowed an ultrasonic probe to act on releasing bioactive compounds without degrading them. All three rheological models were suitable, with the Power Law model being the most appropriate, exhibiting non-Newtonian pseudoplastic behavior. |
