Formulation and evaluation of guapeva jam: nutritional properties, bioactive compounds, and volatile compounds during storage

Abstract

The guapeva (Pouteria cf. gardneriana Radlk.) is a Brazilian fruit that belongs to the Sapotaceae family and is considered a source of natural antioxidants and phenolic compounds; Thus, the objective of this work was to investigate the use of guapeva in the form of jam stored at different temperatures (25 °C and 35 °C) and to evaluate the degradation kinetics regarding the physicochemical parameters, bioactive compounds, and volatile profile, during the storage period of 150 days, in low-density polypropylene packaging's. The stored jams were mainly influenced by the storage time variable, with significant reductions in titratable acidity, pH, color, vitamin C, carotenoids, ABTS •+ , DPPH, and volatile profile. The temperatures studied were not able to significantly affect the shelf life determined for the jams; however, the best temperature for storage stability of the guapeva jams was 25 °C since the most significant degradation of the compounds occurs with the use of 35 °C. The correlation between time and temperature had no significant effect on carotenoid content.

Estabilidade da atividade antioxidante e compostos bioativos da geleia de Araticum (Annona Crassiflora Mart.) em diferentes embalagens e temperaturas

“…É possível observar que a atividade antioxidante diminuiu expressamente nos doces armazenados a 35ºC em ambas as embalagens, de 76,53 no T0, para PP = 264,14 e PE = 206,50 g de geleia/g de DPPH, ao fim do armazenamento. A redução poderia ser explicada pela degradação de compostos bioativos termo sensíveis como antocianinas, flavonoides e ácido ascórbico em produtos submetidos a temperaturas acima de 20°C [15], [16]. Observou-se o incremento significativo do teor de carotenoides totais nos doces armazenados a temperatura de 35ºC, (Fig.…”

Fruits of the Brazilian Cerrado are a potential alternative for food tourism and regional development

“…During the harvest period of each native species, many families of producers, inhabitants of agricultural villages or on the outskirts of the cities, reduce other activities to dedicate themselves to extractivism, which guarantees them, for a few months, an income sometimes superior to that from other activities carried out during the year (Morais et al, 2022b). The extractive exploitation of fruit from Cerrado forms several productive chains.…”

“…Some of these fruits are already available to purchase and consume in large urban agglomerations (such as Brasília and São Paulo) and, thus, visible to a higher number of people by the domestic and international visitors and tourist flow. These highlighted attention fruits are pequi, baru, Cerrado cashew, buriti, araticum, bacupari, guapeva, and mangaba (Leão et al, 2017;Morais et al, 2020Morais et al, , 2022bOliveira et al, 2020).…”
