“…Increase in phenolic, flavonoid, and vitamin C contents in SA‐treated plants did not always occur because it depended on the SA concentration. Increased vitamin C content also contributed to the ROS scavenging activity [21,24] . The phenolic, flavonoid, and vitamin C contents of wheatgrass extracts treated with SA, up to a certain concentration (1.00 mM), were increased.…”

This study was undertaken to determine the influence of salicylic acid (SA) on the bioactive phytochemicals and antioxidant capacity of wheatgrass extract in the organic growing medium. Wheatgrass was cultivated in SA‐enriched organic growing medium, obtained from acetylsalicylic acid (aspirin) of various concentrations (0 [control], 0.25, 0.50, 1.00, and 2.00 mM) in a plant growth chamber by controlling atmosphere (20/15 °C, day/night), light (14/10 h, light/dark; light intensity 150 μmol m−2 s−1, using quantum dot light‐emitting diodes), and atmospheric moisture (60 %) for 10 d. The 0.25 mM SA‐treatment showed the highest impact on germination rate, wheatgrass length, weight, yield, and chlorophyll content. Levels of bioactive phytochemicals, mainly phenolic compounds, flavonoids, β‐carotene, and vitamin C, were the highest in the 1.00 mM SA‐treated wheatgrass extract. The DPPH radical and nitrite‐scavenging capacities were the highest in the 1.00 mM SA‐treated wheatgrass extract. The 0.50 mM SA‐treated wheatgrass extract showed the highest superoxide dismutase‐like capacity, whereas the 2.00 mM SA‐treated wheatgrass extract showed the highest anthocyanin content and ABTS radical‐scavenging capacity. Therefore, it might be suggested that the appropriate levels of SA‐treatment were between 0.5 and 1.0 mM to enhance the bioactive phytochemicals and antioxidant capacity of wheatgrass.

Reggio Calabria province (South Italy) is known for being almost the only area of cultivation of the bergamot fruit, grown principally for its essential oil, but today much studied for the health benefits of its juice. The biometrics and physico-chemical properties of the three (Citrus bergamia Risso) existing genotypes namely Castagnaro, Fantastico and Femminello were studied during fruit ripening from October to March. Castagnaro cultivar had the biggest and heaviest fruit during this harvest period. °Brix (7.9–10.0), pH (2.2–2.8) and formol number (1.47–2.37 mL NaOH 0.1 N/100 mL) were shown to be influenced by both the genotype and harvest date. Titratable acidity (34.98–59.50 g/L) and vitamin C (ascorbic acid) (341–867 g/L) decreased during fruit ripening. The evolution of flavonoids such as neoeriocitrin, naringin, neohesperidin, brutieridin and melitidin was studied both in bergamot juice and in the bergamot cloudy juice which is the aqueous extract of bergamot during fruit processing. Bergamot cloudy juice contained a higher quantity of flavonoids compared to the juice. This study gives important information regarding the cultivar and the harvest date for producers who want to obtain the highest juice quantity or the highest juice quality from the bergamot fruit.

BACKGROUND Red onion is popular in cuisines worldwide and is valued for its potential medicinal properties. Red onion is an important source of several phytonutrients such as flavonoids, thiosulfinates and other sulfur compounds, recognized as important elements of the diet. Nowadays, there is the need of producing food enriched in health benefit compounds. In this study, pads of sulfur bentonite (SB) with the addition of orange residue (OR) or olive pomace (OP) were used to improve the quality of red onion. The experiment was conducted for 3 months in the field to evaluate the phytochemicals of differently amended red onion. RESULTS Treated plants were better in quality than controls. Antioxidant activity, detected as DPPH, ORAC and ABTS, was highest in plants grown in the presence of SB enriched with agricultural wastes, particularly SB‐OR. Polyphenols increased in all treated plants. The volatile fraction was clearly dominated by sulfur compounds that are strictly related to the concentration of the aroma precursors S‐alkenyl cysteine sulfoxides. The greater amount of thiosulfinates in treated compared with untreated onion evidenced that SB pelletized with agricultural wastes can represent a new formulation of organic fertilizer able to improve the beneficial properties of onion. The results highlighted that the best red onion quality was obtained using SB‐OR pads. CONCLUSION The use of SB bound with agricultural wastes represents a novel strategy to increase bio‐compounds with beneficial effects on human health, to enhance the medical and economic values of sulfur‐loving crops, with important consequences on the bio and green economy. © 2019 Society of Chemical Industry
