Influence of preservation methods on the bioactivity of mangaba (Hancornia speciosa Gomes) from the Brazilian savannah

Abstract

This study aimed to evaluate the behavior of the bioactive compounds and the antioxidant activity of raw mangaba fruit (Hancornia speciosa Gomes), in addition to the influence of preservation methods (freezing, lyophilization, and foam layer drying) on these biocompounds. Samples were evaluated for ascorbic acid, phenolic compound, and carotenoid content and total antioxidant activity by the DPPH, ABTS, and FRAP methods. The analyses were performed in triplicate for each sample and the results were expressed as the mean ± standard deviation. A significant correlation was observed between the content of total phenolic compounds and the total antioxidant activity, as determined by the FRAP method, which showed that the content of ascorbic acid contributed to the antioxidant activity of the samples. The lyophilization process produced the best results for ascorbic acid (372.80 mg/100 g), phenolic compounds (408.86 mg AGE/100 g), and carotenoids (0.19 mg/100 g). Therefore, as mangaba may be consumed as both a fresh fruit and in a processed form, new markets can be conquered, enabling the fruit to be used as functional food.

Bioactive profile of mandacaru fruits and cytotoxicity against the L929 cell line

“…Vitamin C concentration determined for mandacaru fruit was low mean values 18.2 mg. 100 g -1 (pulp) and 27.5 mg.100 g -1 (peel), when compared to other fruits also found in Caatinga, such as mangaba (193.07 mg. 100 g -1 ) (Paula et al, 2019), with the concentration found for mandacaru pulp being twice the result found in the fruit peel.…”

Pharmaceutical, food potential, and molecular data of Hancornia speciosa Gomes: a systematic review

“…The studies on the methods used for the preservation of the nutritional compounds (freezing, drying, pasteurization, and lyophilization) were also grouped with the bioactive and antioxidant activities of the pulp (Paula et al 2019;Zitha et al 2020) to short postharvest longevity which is a characteristic that limits the commercialization of the fresh fruit. The potential of latex was also reported as a biomaterial for a biomembrane with angiogenic, anti-inflammatory, and antibacterial activities (Almeida et al 2019), as well as anti-biofilm activities in the regeneration of skin wounds (Bonete et al 2020).…”

“…The fruits are harvested mainly by extractivist that chosen them from natural populations in local communities. H. speciosa research on domestication and agronomic techniques for sustainable and commercial cultivation is still in its early stages (Paula et al 2019 ). There are indications that commercial plantations are being established in the Northeast and Midwest regions.…”

“…Regarding the lipophilic phytochemicals present in mangaba, there are the carotenoids with variations from 0.18 to 1.26 mg [ 42 , 43 ], and also some of the volatile compounds mentioned above. The carotenoids and anthocyanins, both present in the fruit, are natural plant pigments, thus giving them yellowish and pinkish colorings, besides their antioxidant capacity and therapeutic action [ 44 ].…”
