“…Recently, Pinto et al . (2022) also observed a decrease in TSS of Concord grape juice, extracted from organic and traditional cultivation system, after post‐harvest UV‐C treatment in comparison with control group. However, in V vinifera grapes, MeJa does not appear to promote significant differences in this parameter for wine.…”

Grape juice is a major source of potential health-promoting bioactive polyphenols, especially for children and those who do not consume wine. Since the subtropical climate may negatively affect the concentrations of grape polyphenols, especially anthocyanins, elicitors such as methyl jasmonate (MeJa) could be used to promote polyphenol biosynthesis. This work aimed at investigating the impact of MeJa treatment on grape juice produced via a traditional low-cost process from two Vitis labrusca cultivars and in two Brazilian regions. The untargeted LC-MS analytical protocol demonstrated that Isabel Precoce juices strongly benefited from MeJa treatment, especially regarding their anthocyanic profile, regardless of the cultivation region. Known MeJa markers in wine and V. vinifera grapes (flavanols, flavonols and stilbenes) in this experiment had mixed behaviours depending on the region/variety/cultivation. Moreover, it was found that all the detected hydroxycinnamates were influenced by the treatment, especially the concentration of their glucosides, which was increased. Glutathione, 2-S-glutathionyl caftaric acid and indole lactic acid glucoside were identified for the first time as MeJa treatment biomarkers in grape products, indicating a possible positive effect on juice antioxidant properties.

“…The evaluation of color parameters indicates that there was an increase in these parameters in all samples during the storage period. Anthocyanins are the pigments responsible for grape color [44]. The identification of anthocyanins in the prepared isotonic beverages showed the presence of acylated and non-acylated glycoside forms of malvidin, petunidin, peonidin, cyanidin, and delphinidin (Figures 1 and 2), with malvidin pigments predominating.…”

The aim of this study was the elaboration of isotonic drinks rich in bioactive compounds and antioxidant activity using organic ingredients and without synthetic additives. Grape juice was used as a natural source of sugars and phenolic compounds, combined with lemon juice and natural flavors from herb and spice extracts. The ingredients were diluted in two types of water with different mineralization, to which three different determined concentrations of salts (sodium chloride and potassium chloride) were added. The beverages had a sugar content ranging from 72.73 ± 0.23 to 78.43 ± 0.06 g/L, total soluble solids between 4.23 ± 0.06 and 4.83 ± 0.29 °Brix, and total acids from 1.75 ± 0.02 to 2.39 ± 0.08 g/L. Generally, antioxidant activity was higher in the beverages flavored with herb and spice extracts, ranging from 3.28 ± 0.01 to 4.27 ± 0.09 µmols Trolox equivalent/mL. Color intensity showed an increase of up to 129.39% in all samples during the storage period, being higher in beverages prepared with high-mineral water and having high pH values. The results of sensory analysis revealed that the flavored beverages had higher values of global perception than the controls. Thus, the functional properties of grape juice have been increased, and these beverages can be alternative natural and healthy products because their formulation is based only on organic and natural ingredients.

“…In this sense, grapes (Vitis labrusca L.) and their derivatives stand out, which have numerous nutritional, pharmacological and therapeutic benefits (Apostolou et al, 2013;Kim et al, 2013;Huang et al, 2015;Devi and Singh, 2017;Lopes et al, 2019), mainly due to the presence of phenolic compounds and their antioxidant activity (Fernandes et al, 2013;Maestre et al, 2013;Pinto et al, 2022).…”

“…Therefore, the present study aimed to verify the cytotoxic activities of diagnostic and therapeutic doses of I-131 in human hepatocellular carcinoma (HepG2/ C3A) and non-tumoral human lung fibroblast (MCR-5) cells. Also, to evaluate the radioprotective effects of whole grape juices produced from the conventional or organic production system, whether or not exposed to type C ultraviolet light irradiation (UV-C), which has been shown to increase the synthesis of flavonoids, anthocyanins and aromatic compounds (Cantos et al, 2001;Maurer et al, 2017;Pinto et al, 2022), without producing cytotoxic or mutagenic substances (Düsman et al, 2014).…”

Cytotoxicity of iodine-131 radiopharmaceutical in tumor and non-tumor human cells and radioprotection by integral juices of Vitis labrusca L.

Iodine-131 (I-131) radioisotope it causes the formation of free radicals, which lead to the formation of cell lesions and the reduction of cell viability. Thus, the use of radioprotectors, especially those from natural sources, which reduce the effects of radiation to healthy tissues, while maintaining the sensitivity of tumor cells, stands out. The objective of the present study was to evaluate the cytoprotective/radioprotective effects of whole grape juices manufactured from the conventional or organic production systems, whether or not exposed to ultraviolet (UV-C) light irradiation. The results showed that I-131 presented a cytotoxic effect on human hepatocellular cells (HepG2/C3A) at concentrations above 1.85 MBq/mL, after 24 and 48 hours of treatment, though all concentrations (0.0037 to 7.40 MBq/mL) were cytotoxic to non-tumor human lung fibroblast (MCR-5) cells, after 48 hours. However, grape juices (10 and 20 µL/mL) did not interfere with the cytotoxic effect of the therapeutic dose of I-131 on tumor cells within 48 hours of treatment, while protecting the non-tumor cells, probably due to its high antioxidant activity. In accordance with their nutraceutical potential, antioxidant and radioprotective activity, these data stimulate in vivo studies on the use of natural products as radioprotectants, such as grape juice, in order to confirm the positive beneficial potential in living organisms.
