“…Finally, the results are consistent with what is reported in the literature for artichoke and other plant species: the quantities of polyphenols in artichoke heads vary depending on the cultivar, environmental conditions, and phenological phase [ 1 , 4 , 7 , 49 , 53 , 54 , 55 , 56 ].…”

Globe artichoke is an ancient herbaceous plant native to the Mediterranean Basin. The edible part of the plant is limited to the fleshy leaves (bracts) and receptacle of a large immature inflorescence (head) that has been shown to be a rich source of bioactive compounds. Nutritional and pharmacological properties of artichoke heads and leaves are attributed mainly to polyphenolic compounds and inulin present at high concentration. In this study, polyphenols were investigated in two artichoke cultivars (Opal and Madrigal) in response to four nitrogen rates and foliar applications of biostimulating products under drip irrigation. Field experiments were carried out over two growing seasons (2015–2016, 2016–2017) in Policoro (MT), Southern Italy, on a deep clay soil in sub-humid climate conditions. Phenolic compounds were isolated and characterized by means of high-performance liquid chromatography with photodiode array detection and electrospray ionization/mass spectrometry (HPLC-DAD-MS/MS) analysis. In both cultivars, caffeoylquinic acids were more abundant when a dose of 100 kg ha−1 of ammonium nitrate was provided, whereas apigenins were not affected by nitrogen fertilization. Luteolins increased in cv Opal and decreased in cv Madrigal following N fertilization. The application of biostimulants (3 L ha−1) favored the accumulation of polyphenols, in particular of caffeoylquinic acids and apigenin, in artichoke heads in both cultivars. The results obtained highlight some positive aspects related to the synergistic effect of nitrogen fertilization and biostimulant foliar application.

“…The 4 °C chilling storage increased the shelf life: from 14 days for unpacked to a minimum of 28 days for packed artichokes, which exhibited neither off‐odour nor injury after this period. These results are in agreement with those of Bianco24 who reported a 7‐days shelf life for artichokes stored at 20 °C, and these of Di Venere et al ,25 who reported a 5‐week shelf life for packed artichokes with polypropylene film. A continuous weight loss was observed with prolonged storage for unpacked artichokes.…”

“…Meanwhile, the use of modified atmosphere packaging delayed the onset of the rapid decrease of FOS content in yacon and resulted in higher FOS content, with MAP 1 having a higher content than MAP 2. This result aligns with the study of Di Venere, et al (2004), in which the modified atmosphere packaging of 'winter' artichoke heads, with the use of plastic films, contributed to counteracting the decline of inulin during storage. FOS content decline was similar for both room temperature and 10°C, showing that low temperatures do not suppress the degradation of FOS, but merely slow down the onset or conversion of FOS degradation.…”

The yacon tuber has gained interest due to its health-promoting components, such as high amounts of fructooligosaccharides (FOS) and phenolic compounds with strong antioxidant properties. However, the high water content and the soft, delicate internal tissues render it highly perishable, leading to significant losses during postharvest handling. The packaging and storage temperatures, two important factors in maintaining quality when storing fresh yacon tubers, were studied. The results showed that modified atmosphere packaging (MAP) combined with low temperature (10Â°C) had positive effects on the visual quality of yacon. Weight loss and shriveling were reduced in MAP compared to the unpacked yacon under room and 10Â°C storage temperatures. The use of MAP under room temperature for an extended storage period was limited by the development of disease and the occurrence of root sprouts and surface cracks in yacon, which reduced its visual quality. FOS hydrolysis by fructan exohydrolase occurred during storage, leading to higher amounts of fructose, glucose, and sucrose. The use of MAP regardless of storage temperature delayed the onset of rapid FOS decline. The total phenolic contents in the range of 4.84-5.98 mg Gallic acid equivalent per gram dry sample and antioxidant activity of yacon did not decrease relative to its initial content. Yacon could be stored at 10Â°C in conjunction with MAP to maintain quality and extend the shelf life of fresh yacon tubers.
