“…Normally, produce obtained from TCS can reach a total bacterial count of 10 6 À10 9 cfu/g, which can be reduced by 2À3 log cfu/g after washing and sanitation practices. On purslane (Portulaca oleracea L.) grown in FL, the initial mesophilic load and Enterobacteria counts load was 2.7À3.0 log cfu/g and 2.1À2.2 log cfu/g, respectively, on processing day (Rodríguez-Hidalgo et al, 2010).…”

“…Besides, any preharvest condition that stresses a plant such as the non-aeration of the nutrient solution could affect the quality and shelf life of the final product. For example, in purslane grown in a floating system, it was demonstrated that aeration treatments did not significantly affect the gas changes pattern within packages, although shoots cultivated without aeration showed a slightly lower total antioxidant capacity during their shelf life (Rodríguez-Hidalgo et al, 2010a).…”

The objective of this research was to study the effects of growing cycle (spring vs. winter) and nutrient solution aeration [no aeration (NA), low aeration (LA) or high aeration (HA)] on yield, quality, and on shelf life as a fresh-cut product of watercress grown in a floating system. The growing cycles lasted 25 days in spring and 39 days in winter. In the spring cycle, the plants had significantly higher yield and antioxidant capacity and lower specific leaf area, total root length, root diameter, length of 0 to 0.5 mm diameter root, and oxalate content than in the winter cycle. The absence of aeration increased the antioxidant capacity and vitamin C content in both cycles. Several adventitious roots developed exogenously from the watercress stem at the nodes as a morphological adaptation to oxygen depletion, particularly in NA conditions. The nitrate, oxalate, Ca2+, K+ contents, and microbial populations were affected by both the cycle and the aeration conditions. Hue angle of the leaves was affected by both the cycle and storage time, and chromaticity and lightness were affected by the three factors (cycle, aeration, and storage time). The global quality was significantly higher (7.8 over 9 points hedonic scale) in the spring cycle than in winter, the score reflecting their marketable value (7.0 over 9 points). The mild dehydration problems observed in the winter cycle that led to a slightly lower overall product quality that could be the result of the development of thinner leaves and also the differences in the respiration rates compared with the spring cycle. In general, the spring cycle led to higher productivity, antioxidant capacity, and Ca2+ and K+ contents and lower oxalate content. Aeration slightly affected the quality of the final product, the plants grown in non-aerated conditions being richer in vitamin C and antioxidants and with lower nitrate content.

“…The use of soilless cultivation systems such as the floating system allows clean and safe vegetables to be obtained for the processing industry. Moreover, being relatively cheap, this technique can be easily implemented at commercial level and promotes efficient water use (Rodríguez-Hidalgo et al 2009). Indeed, its application for growing fresh-cut vegetables has increased steadily in recent years (Tomasi et al 2015), only inhibited by water quality and availability (Acosta et al 2011).…”

The response of watercress (Nasturtium officinale L.) to salinity has been scarcely addressed in literature despite its growing importance in the baby-leaf market and its wide cultivation in salt-affected agricultural regions. This work evaluates the effect of salinity (2.5, 5 and 10 dS m-1) on productive and quality features of watercress compared with another crop widely cultivated for the baby-leaf sector (lettuce, Lactuca sativa). In watercress, a linear relationship (R2=0.75) was observed between yield decrease and Cl– accumulation in leaves, whereas yield was not affected by salinity in lettuce. NaCl application increased Na+ accumulation at the expense of Ca2+ uptake in the leaf tissues of both crops, but also of K+ in watercress. Health-related features were improved by salinity (e.g. increased phenolics and reduced nitrates), especially in watercress, with limited sensorial quality evaluation effects.
