Biochemical Composition and Sensory Evaluation of Desert Date Flowers (Balanites aegyptiaca Del) Infusion

Abstract

Desert date tea (DDT) is originated from the local Balanites aegyptiaca flowers infusion. Thus, the objectif of this work is to evaluate the antioxidant activity, phenolic contents and the sensory quality of DDT. The antioxidant activity was determined, total phenols and total flavonoids were quantified. Total phenols and flavonoids followed LC-MS analysis, and sensory evaluation were also carried out. Substantial quantities were recorded for both quantity of phenolic and flavonoids accounted for 3.06 mg galic acid /g and 21.60 mg rutin /g respectively. Compounds like narcissin, hirsutrin, quercetrin, ilixantrin, rutin, isorhamnetin and diverse flavone were identified. Lower antioxidant activity and overall acceptability of DDT were noticed than that of quercetin and commercial green tea. The sensory result showed again that the green tea and DDT scored almost the same in flavor character. It can be concluded that DDT could be widely used as a source of polyphenols with antioxidant and sensory quality potential; therefore, introducing numerous health benefits for the consumer.

Phytochemicals, Antioxidant Activity and Ethnobotanical Uses of Balanites aegyptiaca (L.) Del. Fruits from the Arid Zone of Mauritania, Northwest Africa

“…However, total flavonoids were significantly higher in the fruit of the arid site of Boutilimit (47.4 ± 6.4 mg QE/100 g DM) than the other sites. Literature data showed a wide range of bioactive compounds and antioxidant potential of B. aegyptiaca fruit pulp of various origins [37][38][39][40][41]. Polyphenol and flavonoid contents found in the present study were lower than those reported by Abdallah et al [37] in methanolic extracts of B. aegyptiaca fruit from Sudan (212 mg GAE/g DM and 11.5 mg QE/g DM, respectively).…”

Comparison of heglig ( Balanites aegyptiaca ) fruit parts in terms of bioactive properties, phenolic component, and mineral content

“…Total phenol and antioxidant activity values of B. aegyptiaca fruit pulp changed between 222.5–396 mg GAE/100 g and 340–750 µmol TEAC/100 g DM, respectively (Abdelaziz et al., 2020). As stated in previous studies, it is understood that various B. aegyptiaca fruit pulp are rich in various bioactive compounds and has antioxidant potential (Abdallah et al., 2012; Amadou et al., 2019). The polyphenol content of the methanolic extract of B. aegyptiaca fruit grown in Sudan was 212 mg GAE/g (dw) (Abdallah et al., 2012).…”

Phytochemical Analysis of the Desert Date Balanites aegyptiaca

“…In a recent study, the metabolomic profiling of B. aegyptiaca leaves showed high contents of bioactive secondary metabolites which was positively reflected in the antioxidant, antimicrobial and anticancer activity of their extracts (Khamis et al, 2020). Flowers of B. aegyptiaca showed high content flavonoids and phenolics which affect positively the antioxidant activity of flower extracts (Amadou et al, 2019). Very few studies were performed to use the phytochemical analysis from spectrophotometer combined with MVDA in metabolomic differentiation among different species of plants.…”
