Physicochemical properties, nutritional value, and antioxidant potential of jackfruit (Artocarpus heterophyllus) pulp and seeds from Cameroon eastern forests

Abstract

This work aimed to study the physicochemical, nutritional, and antioxidant characteristics of the pulp and seeds of the jackfruit collected in the East Cameroon region to reduce the malnutrition problems encountered in the said region. To achieve this work, we first administered a survey. We observed that 50 people from Bertoua knew the fruit among the 200 people surveyed. After that, the physicochemical characteristics and nutritional value of Artocarpus heterophyllus pulp and seeds from Bertoua were evaluated. Finally, the antioxidant compounds (total phenolic and flavonoid contents) and the antioxidant activities were evaluated through the DPPH free radical scavenging capacity, the ability to reduce ferric ions, and the hydroxyl radical scavenging ability using the aqueous, ethanolic, and hydro‐ethanolic extracts of these samples (pulp and seeds). Results (means ± standard deviation) were obtained in triplicate and analyzed statistically by the analysis of variance (ANOVA) at the 0.05 probability level. The results revealed that the jackfruit pulp has a water content (89.85% ± 0.49) significantly higher than that of seeds (60.075% ± 0.12). The pH of jackfruit pulp (5 ± 0) is significantly lower than that of seeds (6 ± 0). Jackfruit pulp had a carbohydrate content (54.39% ± 0.47) significantly higher than that of seeds (49.01% ± 0.43). The protein content of jackfruit pulp (18.35% ± 0.04) is lower than that of the seeds (21.66% ± 0.31). For mineral content, the maximum contents of K (848 mg/100 g ± 10.34) and Na (69.53 mg/100 g ± 0) were identified in the jackfruit pulp while those of Ca (132 mg/100 g ± 9.42), Mg (43.73 mg/100 g ± 9.12), and P (101.51 mg/100 g ± 4.02) were found in the seeds. However, all extracts possessed both antioxidant compounds (phenols and flavonoids) and antioxidant activities. In conclusion, the jackfruit appears to be a fruit that can improve the nutritional status of the populations of eastern Cameroon.

“…[29]. The mineral content is noteworthy because these values are comparable to mango, soursop, and jackfruit, ranging from 0.01 g/100 g to 0.42 g/100 g [30][31][32].…”
