Smooth golden fleece (Urospermum dalechampii (L.) F.W. Schmidt) and prickly golden fleece (Urospermum picroides (L.) Scop. ex F.W. Schmid) are two wild edible plants used in traditional cuisine and folk medicine. In this research, the domestication of both species was tested for the first time using a floating system and two plant densities (412 and 824 plants m−2) to evaluate yield and quality. Some quality traits were also compared in cultivated plants and wild ones gathered in grasslands. The results show that both species are suitable for cultivation, although prickly golden fleece showed highest total phenols (132 mg 100 g−1 fresh weight—f.w.) and total antioxidant activity (0.19 mg 100 g−1 f.w.). At low sowing density, smooth golden fleece showed a nitrate content of about 7200 mg kg−1 f.w., 38% higher than plants of the same species grown at high density and plants of prickly golden fleece. These results suggest that high density can be used to optimize yield in two harvests. By permitting modulation of nutrients and a product without soil residues, the floating system used in this study proved suitable for growing U. dalechhampii and U. picroides as new vegetables for the ready-to-eat production chain.

The study aimed to assess the influence of three cooking methods (boiling, steaming, and microwave-cooking) on (i) composition in individual phenolic compounds, (ii) total phenolic content (TPC), and (iii) total antioxidant activity (TAA) of eight Mediterranean wild edible species (Asparagus acutifolius, Asphodeline lutea, Beta vulgaris, Helminthotheca echioides, Sonchus oleraceus, Taraxacum officinale, Urospermum picroides, Urtica dioica). In raw greens, several caffeic acid derivatives (chicoric, caftaric, chlorogenic, neochlorogenic, 1,5-and 3,5-dicaffeoylquinic acids) and flavonoids (glycosides of apigenin, luteolin, quercetin, isorhamnetin, kaempferol) were identified. Cooking treatments did not affect qualitative phenolic composition, while quantitative changes were recorded in some phenolic compounds and in TPC. Generally, boiling decreased TPC and TAA, while chicoric, caftaric, chlorogenic acids and quercetin-3-rutinoside increased in some species after steaming and microwave-cooking, showing positive correlation with TAA. Results confirmed steaming and microwave-cooking as mild procedures able to increase antioxidant capacity of some species, producing beneficial effects on their nutraceutical properties.

Wild rocket (Diplotaxis tenuifolia L. DC) is an emerging vegetable which market requires high-quality standards that can be obtained through appropriate cultivation techniques such as the right level of nitrogen and the application of biostimulant substances. These include strobilurins, marketed mainly as fungicides that can have complementary positive effects on the yield, quality and resources’ use efficiency of many crops. For this reason, a trial in an unheated greenhouse, in Southern Italy, to evaluate the possibility of using Azoxystrobin to improve the production of wild rocket subjected to different nitrogen inputs, was carried out. Two N levels (40 and 140 kg ha−1), Azoxystrobin-based biostimulant (Azo+) and control without Azoxystrobin (Azo−) were compared. The yield, morphological characteristics, nitrogen and water use efficiency (NUE, WUE), antioxidant activity, the content of dry matter, chlorophyll, carotenoids, phenols, and nitrates were assessed. A higher N level resulted in a 16.3% yield increase that was matched by a 12.5% reduction in NUE, 15.8, 7.3, and 16.1% increases in yield WUE (Y_WUE), biomass WUE (B_WUE), and irrigation yield WUE (IY_WUE), respectively, and a worsening of some qualitative characteristics such as a 8.5% rise in nitrates, and a decline by 11.5, 10.1, and 26.1% in the carotenoids, phenols, and antioxidant activity, respectively. Azo+ increased the yield by 10.3%, NUE by 8.9%, and Y_WUE, B_WUE, and IY_WUE, by 13.9, 9.1, and 13.8% respectively. Moreover, Azo+ improved some qualitative characteristics such as total phenols (+9.4%), chlorophyll (+15.2%), carotenoids (+9.7%), and antioxidant activity (+17.4%), while it did not affect the nitrate content. Azoxystrobin can be an additional tool available for farmers to ensure high-quality standards of wild rocket.

Ligninolytic enzymes from white-rot fungi, such as laccase (Lac) and Mn-peroxidase (MnP), are able to degrade aflatoxin B1 (AFB1), the most harmful among the known mycotoxins. The high cost of purification of these enzymes has limited their implementation into practical technologies. Every year, tons of spent mushroom substrate (SMS) are produced as a by-product of edible mushroom cultivation, such as Pleurotus spp., and disposed at a cost for farmers. SMS may still bea source of ligninolytic enzymes useful for AFB1 degradation. The in vitro AFB1-degradative activity of an SMS crude extract (SMSE) was investigated. Results show that: (1) in SMSE, high Lac activity (4 U g−1 dry matter) and low MnP activity (0.4 U g−1 dry matter) were present; (2) after 1 d of incubation at 25 °C, the SMSE was able to degrade more than 50% of AFB1, whereas after 3 and 7 d of incubation, the percentage of degradation reached the values of 75% and 90%, respectively; (3) with increasing pH values, the degradation percentage increased, reaching 90% after 3 d at pH 8. Based on these results, SMS proved to be a suitable source of AFB1 degrading enzymes and the use of SMSE to detoxify AFB1 contaminated commodities appears conceivable.

Processing tomato is a widespread crop in the Mediterranean area where often there are problems of high salinity of irrigation water with considerable harmful effects on yield. Pyraclostrobin is a strobilurin based fungicide (PBF) having a broad range of applications. Strobilurins are reported to have biostimulant effect on plant mitigating abiotic stress. Therefore, the objective of this work was to investigate the ability of PBF to improve gas exchange parameters, chlorophyll, activity of antioxidative enzymes as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), yield characteristics, and water use efficiency (WUE) of tomato under salinity. A two-year research was carried out in Southern Italy, on tomato cv Coronel grown in pots under plastic greenhouse, to compare two soil salinity levels (electrical conductivity, ECe = 1.1 and 5.4 dS m−1) in combination with or without PBF. As expected, salinity had harmful effects on physiological and biochemical parameters of tomato that in turn affected yield and WUE, but improved fruit quality. In fact, salinity reduced fruit mean weight (19.0%) and yield (21.4%), and increased fruit blossom-end rot (55.7%), total soluble solids (18.2%) and dry matter (18.5%) content. Overall, PBF increased leaf chlorophyll content (6.1%) and the activity of SOD, POD, CAT and APX, mainly under salinity. Moreover, it reduced stomatal conductance (12.5%) and transpiration (11.7%), but improved assimilation rate (7.8%) and intrinsic WUE (23.3%), that in turn increased yield (8.1%) and yield WUE (6.5%). The improvement in yield produced by PBF was highest in salt stressed plants. In view of the positive effects of PBF, its use should be promoted in defence programs of tomato crop, above all in areas with salinity problems.

The cultivation of wild asparagus does not require many input because it adapts very easily to adverse pedoclimatic conditions. The main limit to its cultivation is the long time necessary for germination and the low germinability of seeds. In this study, the effect of cold plasma pretreatment on wild asparagus seed germination was evaluated. Seed plasma pretreatments (mixtures of O2/N2 applied for different times) were compared with conventional ones, namely: soaking (water), priming (polyethylene glycol), and hormonal (gibberellic acid). The effects of seed stratification and temperature on germination were also investigated. The stratification reduced the time required for germination of about 180 d. Plasma treatment, gas feed with 20–80% O2/N2 for 1 min, resulted more effective in increasing the germination percentage (by 15%) and reduced of 5 d the time to reach half of maximum germination percentage (T50). This performance is related to both the increase in water uptake and the fungal disinfectant properties of plasma treatment. This study confirms that the application of cheap and eco-friendly cold plasma technology could provide improvements in the cultivation of wild asparagus.

Postharvest treatments with extracts from two wild edible plants (Orobanche crenata and Sanguisorba minor), water solutions of two inorganic salts (calcium chloride, CaCl2, and sodium bicarbonate, NaHCO3), and their combination (i.e., extracts with added CaCl2 or NaHCO3), were assayed to control sweet cherry postharvest diseases. Three extract concentrations for each plant were assayed, corresponding to 0.170, 0.340, and 0.510 g dry matter/mL and to 0.125, 0.250, and 0.500 g dry matter/mL for S. minor and O. crenata, respectively. At the lowest and the highest concentrations tested, S. minor extract was able to inhibit rot development in stored fruit by 79 and 89%, respectively, with an efficacy comparable to that of CaCl2 and NaHCO3; for O. crenata extract such inhibition ranged between 64 and 76%, respectively. A dose effect was observed only for O. crenata. Moreover, the level of control was not improved by the combined application of plant extracts and salts. HPLC analysis of O. crenata extract showed verbascoside as the main phenolic compound, being about 95% of total phenolics; S. minor phenolic pattern appeared to be more complex, due to the presence of caffeic acid derivatives, quercetin-3-glucoside, kaempferol-3-glucoside and other quercetin, kaempferol, and luteolin derivatives, as well as many other unidentified compounds. Residues of phenolics resulting from plant extracts in treated sweet cherries after storage were below the analytical limit of detection. The study demonstrated that S. minor and O. crenata extracts might represent an alternative organic mean for controlling sweet cherry postharvest decay

Efficient utilization of saline land for food cultivation can increase agricultural productivity and rural income. To obtain information on the salt tolerance/susceptibility of wild chicory (Cichorium intybus L.), the influence of salinity (0–260 mM NaCl) on chicory seed germination and that of two salinity levels of irrigation water (100 and 200 mM NaCl) on plant growth, antioxidative enzyme activity, and accumulation of proline and malondialdehyde (MDA) were investigated. The trials were performed outdoors, in pots placed under a protective glass covering, for two consecutive years. Seeds showed a high capacity to germinate in saline conditions. The use of 100 mM NaCl solution resulted in 81 % germination, whereas seed germinability decreased below 40 % using salt concentrations above 200 mM NaCl. Wild chicory showed tolerance to medium salinity (100 mM NaCl), whereas a drastic reduction in biomass was observed when 200 mM NaCl solution was used for irrigation. MDA, present in higher amounts in leaves than in roots, decreased in both tissues under increasing salinity. Proline content increased remarkably with the level of salt stress, more so in roots than in leaves. In salt stress conditions, the activity of antioxidant enzymes (APX, CAT, POD, SOD) was enhanced. The electrophoretic patterns of the studied enzymes showed that the salinity of irrigation water affected only the intensity of bands, but did not activate new isoforms. Our results suggest that wild chicory is able to grow in soil with moderate salinity by activating antioxidative responses both in roots and leaves.

The quality of leafy vegetables has to be guaranteed for consumers over the whole postharvest period, usually limited to 5–7 days. The analyses to evaluate the quality of vegetables are very time- and resource consuming, so the use of qualitative markers can be much useful. The aim of this work was to evaluate the use of thermoluminescence (TL) parameters as qualitative markers of fresh-cut leafy vegetables during the shelf life. TL is a technique consisting of a cooling, followed by the progressive warming, of a preilluminated sample to reveal the different types of charge pairs as successive emission bands, which are resolved better than the corresponding decay phases recorded at constant temperature. Experiments were performed on rocket (Diplotaxis tenuifolia L.) stored at 2 °C for 7 days. During storage, several changes in TL glow curves were found. The position of the peaks showed a shift to higher temperature. The area of the peaks, relating to the photosystem II (20–65 °C), grew up lightly; whereas in the temperature range that detects lipidic peroxidation (65–140 °C), the TL emission became more than twice. These changes demonstrated that, during the shelf life, a progressive destabilization of PSII centres occurred and that lipid peroxidation products were accumulated in membranes. TL could be used to estimate the damages immediately after as well as during the storage period. This is the first time that TL was used to evaluate the quality of fresh-cut vegetables products during the shelf life.

A cationic soluble peroxidase isoenzyme (CysPrx) has been purified and characterized from artichoke (Cynara cardunculus subsp. scolymus (L.) Hegi) leaves by combination of aqueous two phase extraction, ion exchange chromatography, and gel filtration. The purification fold was 149 and the activity recovery 5.5%. CysPrx was stable from 5 to 45 °C with a pH optimum around 5.5; the pI was 8.3 and the MW of 37.7 ± 1.5 kDa. MALDI-TOF MS analysis provided partial peptide sequences and resolved CysPrx isoenzyme into two putative isoforms. The presence of these isoforms was confirmed by the isolation of full-length cDNA encoding CysPrx that generate two slightly different sequences coding for two putative CysPrx: CysPrx1 and CysPrx2. The obtained MS peptides showed a 35% coverage with 100% identity with the two CysPrx deduced protein sequences. A molecular modeling analysis was carried out to predict in silico the protein structure and compare it with other plant Prx structures. Considering that CysPrx is quite stable, the study carried out in this paper will offer new insights for the production of the recombinant protein for utilization of CysPrx as an alternative Prx for food technology, biomedical analysis and bioremediation.

The yeast population dynamics in olive wastewaters (OMW), sampled in five mills from Salento (Apulia, Southern Italy), were investigated. Three hundred yeasts were isolated in five industrial mills and identified by molecular analysis. Strains belonging to Geotrichum, Saccharomyces, Pichia, Rhodotorula and Candida were detected. Five G. candidum strains were able to grow in OMW as the sole carbon source and to reduce phenolics, chemical oxygen demand (COD) and antimicrobial compounds. One G. candidum isolate was selected for whole-cell immobilization in calcium alginate gel. The COD and phenolic reduction obtained with immobilized cells showed a 2.2- and 2-fold increase compared to the removal obtained with free cells, respectively. The immobilization system enhanced yeast oxidative activity by avoiding the presence of microbial protease in treated OMW. To our knowledge, this is the first report on G. candidum whole-cell immobilization for OMW bioremediation.

Peroxidases are part of a large group of enzymes associated with cell wall biosynthesis, response to injury, disease, resistance and wound repair. Among peroxidase isoenzymes, a soluble cationic peroxidase (ALSP), not yet described, has been partially purified and characterized from artichoke leaves. The enzyme was shown to be a glycoprotein with a molecular weight of 51 000 and an isoelectric point of 9. The substrate specificity of the ALSP is characteristic of class III (guaiacol‐type) peroxidases. The ALSP was partially purified by ammonium sulfate precipitation, gel filtration, affinity chromatography, anionic exchange high‐performance liquid chromatography and isoelectrofocusing. The increase in specific activity was 43 times compared to the crude extract as estimated by the guaiacol assay. Three ALSP fragments were sequenced by tandem mass spectrometry de novo sequencing method. Copyright © 2007 Society of Chemical Industry
