Chemical characterization of different parts of noni (Morinda citrifolia) fruit and its freeze-dried pulp powder with emphasis on its bioactive compounds and antioxidant activities

Abstract

The aim of this study was to prepare the freeze dried powder of noni (Morinda citrifolia) pulp and determine the contents of bioactive and antioxidant capacity. Seed, peel, pulp and lyophilized powder were characterized in terms of physico-chemical, carotenoids, chlorophyll, sugars, ascorbic acid, phenolics, flavonoids and antioxidants contents. Phenolic compounds were determined by LC-MS. The lyophilized pulp powder showed high levels of phenolics and flavonoids (7486.38 µg GAE/g and 385.57 µg QE/g, respectively) and higher antioxidant activity for FRAP (10360.39 to 467970.40 mmol/100 g). Ascorbic acid has a higher concentration in the lyophilized powder (336.62 mg/100 g). Rutin, caffeic, artepillin C, quercetin-3-glucoside, kaempferol, vanillin and vanillic were the major compounds. The antioxidant effect present in the various components of the fruit was predominant, and the greater conservation of this potential was through the application of lyophilization. Thus, the noni may be considered as a good source of phenolics compounds having a high potential as natural antioxidants.

Valorization of the Noni (Morinda citrifolia) Seeds as Source of a Protein Concentrate and Its Physicochemical, Functional, and Structural Characterization

“…The main residue from the processing of the noni fruit is the seeds, which represent approximately 2.5% of its weight and contain considerable amounts of carbohydrates, proteins, oil, dietary ber and ash [22,23], as well as bioactive substances such as polyphenols, avonoids, and carotenoids [24]. Polyphenols possess antioxidant, antimutagenic and antitumor properties, avonoids have free radical scavenging capacity, anti-in ammatory, antiallergic, antiviral and anticancer properties, while carotenoids contribute to the health system due to cell communication, antioxidant activity, immune function, provitamin A activity and skin protection against ultraviolet damage [17].…”

Comparative Cytotoxic Assessment of Hydro-Methanolic Extracts Derived from Ripe Morinda citrifolia L. Fruit (Fresh, Dried, Pasteurized Juice) and Dried Seeds on Eukaryotic Normal and Carcinogenic Cellular Models

“…Noni seeds are also a potential source of functional food [7], and Noni seed oil (NSO) is non-toxic [8] and possesses a unique fatty acid composition, rendering it an attractive option for utilization in the food, pharmaceutical, and cosmetic industries. This offers potential benefits in terms of enhancing nutritional quality [9], structural attributes, aroma, and stability in various formulated food products [10,11].…”
