“…The radical scavenging activity of RGP, DGP and GPE compared to standard substances AA and BHT was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay [ 38 ]. To prepare the ethanolic extracts of RGP and DGP, a quantity of each ground sample that provided 1 g of dry substance (d.s.)…”

Exploring new sources of natural antioxidants is of great interest to edible oil producers, in line with the toxicological problems generated by the use of synthetic antioxidants. This study assesses the potential of lyophilized Pinot Noir grape pomace extract (GPE) to enhance the sunflower oil stability against thermo-oxidative damage compared to BHT during a prolonged exposure to convective heat at 185 °C. Oil thermo-oxidation was monitored based on specific indices such as peroxide value (PV), para-anisidine value (p-AV), inhibition of oil oxidation (IO), total oxidation (TOTOX) value, conjugated dienes and trienes (CDs, CTs), but also by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), where absorbance ratios A 3009 cm−1/A 2922 cm−1 (RI), A 3009 cm−1/A 2853 cm−1 (RII), A 3009 cm−1/A 1744 cm−1 (RIII) and RIV = A 1744 cm−1/A 2922 cm−1 (RIV) were investigated. GPE showed a significant inhibitory effect on oil thermo-oxidation and this response was concentration-dependent. Substantial decreases in the investigated indices, compared to the control without added antioxidants, were obtained after 4 h and 8 h of heat exposure of the 800 ppm GPE sample: PV (47%; 42%), p-AV (38%; 33%), IO (54%; 46%), TOTOX (41%; 37%), CDs (46%; 39%), CTs (44%; 29%). Oil exposure to heat resulted in changes in RI–RIV attributed to the reduction in the degree of unsaturation, in response to primary and secondary lipid oxidation. FTIR spectroscopy can be used to differentiate untreated and heat-treated oils based on the absorbance ratios. An inhibitory effect close to that of BHT was achieved by 500 ppm GPE, while a dose of 800 ppm provided greater protection against thermo-oxidation. Our results promote GPE as a natural additive to limit the thermo-oxidative damage of plant oils.

“…Another study on the metabolomic profiling and antioxidant activities of Hyphaene thebaica found that the fruit exhibited antioxidant activities (Taha et al, 2020). A study by Thi et al (2020) on the screening for antioxidant activity of vegetable and fruit by-products found that most samples had weak antioxidant activity, and the effect of antioxidants on DPPH radical scavenging was due to their hydrogen donating ability (Thi et al, 2020). Based on the comparison with previous studies, it is evident that the current study aligns with the broader research landscape on antioxidant activities of fruits and their extracts.…”

The medicinal properties of fruits are closely related to their available phytochemicals, as well as antioxidant capacity. Many of the indigenous fruits have been traditionally used as folk medicine. This study aims to evaluate the phytochemicals, mineral elements, and antioxidant properties of five (5) commonly consumed desert fruits such as Hyphaene thebaica, Detarium senegalensce, Ziziphus jujuba, Dialium guineense and Diospyros mespiliformis. The phytochemicals, mineral elements, and antioxidants were carried out using standard methods of analysis. The result revealed that phytochemicals such as alkaloids, flavonoids, phenols, tannins, saponins, steroids, terpenoids, and glycosides were present in all five fruits studied with varied compositions. While the mineral elements such as Potassium (K), Magnesium (Mg), Calcium (Ca), Sodium (Na), Iron (Fe), Manganese (Mn), Zinc (Zn), and Copper (Cu) were present indicated that the fruits have substantial mineral elements, however, varied according to the fruits species studied, Hyphaene thebaica exhibits the highest elemental content. The DPPH inhibition properties emphasize the diverse antioxidant capabilities of the studied fruits in which Diospyrosme spiliformis (DS) emerges as a standout in DPPH inhibition activity, exhibiting robust antioxidant activity, closely followed by Dialium guineense (DG). The nitric oxide radical scavenging reveals a concentration-dependent response in the NO radicals scavenging activity for all the fruits and ascorbic acid. The findings conclude that the five desert fruits species revealed different phyto-constituents, mineral elements, Nitric oxide radical scavenging effect, and DPPH inhibition properties suggesting potential medicinal and nutritional properties of the five desert fruits.

“…They are rich in bioactive compounds, which can be utilized as novel, low-cost natural sources of antioxidants, antimicrobials, dietary fiber, enzymes, and food additives through different methods of extraction, purification, and fermentation ( Gowe, 2015 ; Kodagoda and Marapana, 2017 ). In a previous study, an ethanol extract of Coffea arabica sediment proved to be one of the most efficient extracts in antioxidant activity and inhibiting tyrosinase ( Hue et al, 2020 ), so it was studied further in this research. This study aimed to examine antioxidant activity and tyrosinase inhibition of an ethanol extract from Coffea arabica sediment and its various fractions.…”

Coffea arabica sediment, a popular agro-by-product from the coffee juice processing industry, contains many phytochemicals, and it is often discarded as waste. The antioxidant and anti-tyrosinase activities of an ethanol extract and its active fractions obtained from Coffea arabica sediment was studied. Additionally, whiteleg shrimp (Litopenaeus vannamei) was treated with the extract and fractions, and the quality during refrigerated storage was evaluated. The most active fraction (P<0.05) fraction III from the Coffea arabica sediment extract showed a total phenolic content of 116.5 mg gallic acid equivalent/g, an inhibitory concentration of 50% value of 27.3 μg/mL in the 2,2-diphenyl-1-picryl hydrazyl test, an absorbance of 3.7 (at 1.0 μg/mL) in the reducing power assay, and 79.5% inhibition for the tyrosinase inhibition test (at 100 μg/mL). Whiteleg shrimp treated with PD-3 and crude extract (CE) retarded the growth of bacteria and spoilage microorganisms in comparison to the control (P<0.05). Lower values in pH, thiobarbituric acid reactive substances, and total volatile base content were enumerated in samples treated with PD-3 and CE (P<0.05) compared to controls. Loss in freshness, protein content, and melanosis formation declined with CE and PD-3 treatments. Our findings showed that Coffea arabica sediment has antioxidant and antimicrobial properties. Also, it could be a promising treatment in melanosis prevention, and a natural additive for extending the shelf life of whiteleg shrimp during refrigerated storage; thus an alternative to traditional sulfites.
