The rose hip fruit, besides carotenoids and polyphenols, are also good sources of lipid substances (fatty acids, sterols and tocopherols), which can be used as functional foods instead of being discarded as waste. The aim of this review is to present an overview of the lipid characterization of rosehip seeds as affected also by the oil extraction procedure.</p> <p>The rosehip seeds oil is proven to be rich in polyunsaturated fatty acid (PUFA), sterols and tocopherols, which provide specific biological activities (anti-inflammatory, anti-obesity, antioxidant, anti-diabetic activity). In particular, the oil content of rose hip seeds ranges from 5 to 18 % and is composed of unsaturated fatty acids such as linoleic acid (36-55 %) which is the most abundant one, linolenic (17-27 %) and oleic acid (15-22 %) respectively. As for the sterols, its content ranges around 5 g/kg constituting predominantly B-Sitosterol, whereas, the tocopherols amount to around 1 g/kg with Y-tocopherol being the most abundant.</p> C.

ECOTYPES <p>In this study, phenolics and reducing sugar` compositions of fig fruits (27 Tunisian ecotypes) were analyzed. In addition, the antioxidant activity was determined by two methods; the ABTS and the DPPH assays. Phytochemical composition of the 27 fig ecotypes was found to be very diverse, as the total polyphenols varied from 51.50 (‘<em>Bouholi’</em>) to 100.23 (‘<em>Nasri’</em>) mg gallic acid equivalent/100 g fresh weight. Total flavonoids also varied from 0.33 (‘<em>Bayoudhi1’</em>) to 17.59 (‘<em>Soltani Ahmar’</em>) mg quercetin equivalent/100 g fresh weight, and total anthocyanins extended from 1.61 (‘<em>Besbessi’</em>) to 11.67 (‘<em>Zidi2’</em>) mg/100 g fresh weight. Additionally, DPPH % inhibition ranged from 11.37 (‘<em>Besbessi’</em>) to 64.73 % (‘<em>Bouharrag’</em>) and ABTS from 38.50 (<em>Sawoudi5</em>) to 676.13 (‘<em>Nemri’</em>). The ecotypes ‘Zergui’ and ‘Nasri’ had the highest contents of glucose (5.68 and 4.83 g/ 100 g FW, respectively) and fructose (5.43 and 4.69 g/ 100 g FW, respectively). The results also showed that fig fruits are a good and valuable source of natural antioxidants that can be used in food and medical sectors.</p> F. ALJANE, M.H. NEILY, A.

The experimental materials included raw tubers and peeled and unpeeled potato tubers that had been cooked. Analyses were conducted immediately after harvest and after 3 months of storage at 5°C and 8°C. Flesh colour significantly affected the AA and TP contents in tubers. The difference between the AA content in cream- and yellow-coloured tubers was 12.5%, and between cream and light-yellow tubers was 16.5%. Differences in TPs between the different flesh colours did not exceed 33%. Significant losses of AA were found in yellow- and light-yellow-fleshed tubers that had been peeled and cooked after harvest (44 and 46%, respectively). Cooking peeled tubers significantly decreased the antioxidant activity in potatoes regardless of the flesh colour and storage treatment. The unpeeled cooked tubers had significantly higher antioxidant activities than raw tubers after harvest. Irrespective of the flesh colour, high linear correlations were found between (AA)×(TE) for cooked peeled tubers. A significant determination coefficient (R<sup>2</sup>) was observed between (TPs)×(TE) for raw and cooked unpeeled light-yellow and yellow-coloured tubers. The linear relationship between TPs and TE after cooking was significant for unpeeled tubers. The greatest matching of the model characteristics of the interdependence of features (?<sup>2</sup>) (AA)x(TE) was 75%, and for the model TPs and TE 80%.</p> M. GRUDZIŃSKA; D.

Herein, we evaluated the effect of the same pre-treatment on the quality attributes of the same dried ‘Annurca’ apple samples rehydrated at two temperatures. Specifically, slabs were initially pre-treated in a dipping solution containing trehalose, sodium chloride, sucrose. Then, they were dried by using a convective dryer at 50°, 55°, 60°, and 65°C, and rehydrated at 30° and 70°C by immersion in water. The combination of pre-treatment, drying at 65°C and rehydration temperature of 30°C enabled to obtain the best preservation of rehydration indices (i.e, water absorption capacity), structure and colour properties. On the contrary, the highest antioxidant activity (EC<sub>50</sub>) in treated samples was found at the lowest drying temperatures (50° and 55°C) among those investigated and rehydration temperature of 30°C. The PCA provided different behaviours among untreated and treated dried apples when rehydrated at 30° and 70°C, demonstrating that this pre-treatment combined with drying/rehydration temperatures influenced the quality attributes of rehydrated samples.</div> B.

The aim of this study was to investigate the psychochemical, rheological, and sensory properties of voluminous breads enriched by different amounts of purslane powder (0, 5, 10, and 15%) were compared to a control group. The results showed that, with an increase in the concentration of Purslane in samples, water absorption capacity, stability under mixer, and softening level increased. Adding 15% of purslane powder decreased farinograph quality number significantly. Addition of purslane powder also improved resistance to extension and decreased extensibility, energy, and viscosity of the dough significantly. In terms of sensory properties, the sample with 15% purslane powder obtained the minimum score and other samples had acceptable conditions in terms of different sensory properties like taste, texture, color, odor, and general acceptability. In summary incorporation of purslane in voluminous bread is feasible and the optimum percentage of the purslane powder is 10% for the best acceptance in sensory evaluation.</div> M.

These compounds are released in the environment as a complex mixture of various congeners which shown significant physico-chemical differences, as well as different environmental fates. PCDD/PCDF mixtures change spatially and temporally in the environment and biota, complicating the risk assessment and regulatory control for human and animal exposure. Considering the well-known role of honeybees as bioindicators for pesticides, heavy metals and other chemicals, the present study has been developed to assess the use of honeybees and honeybee products in biomonitoring projects about PCDD/PCDFs. &nbsp;Three Dadant-Blatt type beehives, located since March 2017 in the headquarter of Ducati Motor Holding S.p.A. (Borgo Panigale, Bologna, Italy) have been used as monitoring stations. Honeybees, honey and beeswax have been sampled and analyzed for PCDD/PCDFs detection in June and in September of the same year. Among the analyzed matrices, beeswax has shown the highest WHO-TEQ values, probably due to its lipidic nature capable of accumulating fat-soluble, non-volatile, persistent organic pollutants. Hexaclorodibenzo-p-dioxin (HxCDD), usually measured in vegetables and fruits, has been detected only in honey samples. Maximum levels of PCDD/PCDFs are settled by Commission Regulation (EC) No 1259/2011 of 2 December 2011, but only on animal-derived products. Considering the role of dietary-model adopted by the consumers on toxic substances dietary intake and associated exposure risks, limits on botanical derived products are needed. But more controls about bee-products are advisable also in order to reduce the exposure risk for bees and for protecting biodiversity.</p> S.M.R. TULINI, R.M. SPECCHIA, O.R. LAI, C. MUCCIOLO, M.

WINE <div>The effects of pretreatment (pectinase and CaCO<sub>3</sub>) and chaptalization (sugar and puree concentrate) on the quality of apricot wine were investigated. Pectinase-treated apricot wines had increased amounts of total phenolics, flavonoid compounds, as well as antioxidant activities. The apricot wine chaptalized with puree concentrate and treated with pectinase (PCP) showed the highest total acidity and some organic acid contents, which resulted in the strongest sourness. In contrast, the apricot wine treated with pectinase and CaCO<sub>3</sub> (SCPC and PCPC) showed the lowest total acidity and least sourness. Antioxidant activities of PCP and PCPC wines were higher than other wines, and other pectinase-treated wines were also higher than the control wine. Volatile higher alcohols and terpenes increased in all the pectinase-treated wines, whereas volatile ester compounds were decreased. Sensory evaluation showed that SCPC, PCP, and PCPC wines obtained significantly high flavor scores, and SCPC and PCPC wines obtained the highest overall preference scores.</div> K.-T. CHOI, S.-B.

Secondary metabolites content showed a significant difference among the evaluated parts. Multivariate data analysis (MVDA) classified the parts into three groups based on their metabolomic profiling and the total antioxidant capacity (TAC) of their extracts. The highest content of secondary metabolites, particularly in the leaves and fruits, was reflected in the DPPH radical scavenging activity and consequently in the IC<sub>50 </sub>of their extracts. The leaves and fruits extracts showed the lowest IC<sub>50</sub>, followed by the male parts extract (62.8, 78.9 and 134.4 ?g/ ml, respectively). Individual polyphenols were also determined by HPLC, which revealed the dominance of rutin, spigenin-7-</div> <div>glucoside, vanillic and rosmarinic acids, and kaempferol in the leaves. p-hydroxybenzoic, caffeic, syringic, sinapic, and cinnamic acids and chrysin were the dominant polyphenols in the male parts extract. Ferulic acid, luteolin and apigenin were the dominant polyphenols in the fruits extract. Medemia argun extracts showed very strong antiproliferative activity against hepatocellular carcinoma (HepG-2) and lung cancer cell lines (A549). Of the three parts that showed very strong antiproliferative activity, the male parts extract showed prominent antiproliferative activity against HepG-2, while the leaves extract showed more prominent activity against A549 (IC<sub>50 </sub>was 0.587 and 1.038?g/ml, respectively). The leaves and fruits extracts showed antimicrobial activity against Bacillus subtilis and Staphylococcus aureus (Gram-positive bacteria) and Pseudomonas aeruginosa (Gram-negative bacteria). The male parts showed moderate antibacterial activity only against B. subtilis. No extracts affected the growth of Escherichia coli, Candida albicans and Aspergillus flavus.

However, the medicinal efficacy of <em>C. songaricum</em> collected in different seasons varies greatly, and the difference in the transformation and accumulation of its major metabolites is still unclear. In this paper, UPLC-QTOF/MS and NMR were used to study the metabolomics of <em>C. songaricum</em> in different growth stages, so as to explore the metabolic differences and regularity of<em> C. songaricum</em> in different phenological periods during one cycle. The results showed that there were thirty and sixteen compounds with significant differences based on UPLC-QTOF/MS and NMR, respectively, which were distributed in flavonoids, organic acids, sugars and amino acids. Among them, the content of secondary metabolites such as catechins and procyanidins accumulated more in the Unearthing (U), and Maturing (M) stages, while other differential compounds accumulated more in the Tubercle (T), Sprouting (S) and Atrophy (A) stages.

SEED OIL LIPID COMPOSITION <p>The most common food using hemp (<em>Cannabis sativa</em> L.) is hempseed oil (HSO) because it is a rich source of nutrients with nutritional and functional beneficial effects for human body. Harvesting time can affect the quality of HSO, consequently the aim of this study was to evaluate the composition of lipid fraction, fatty acids, tocopherols and sterols, during ripening. Two cultivars, <em>Futura 75</em> and <em>Carmagnola</em>, were collected at three ripening stages during August and September 2015 and their lipid composition was determined by analytical techniques. Among the fatty acid identified, the linoleic acid was the preponderant, followed by oleic, a-linolenic and palmitic acid. Linoleic:a-linolenic acid and polyunsaturated:saturated fatty acid ratios decreased and increased, respectively, in both varieties with ripening. y-tocopherol was the preponderant tocopherol identified, <em>Futura 75</em> showed the highest content in the middle of maturation while <em>Carmagnola</em> at the beginning. B-sitosterol was the predominant sterol identified in both varieties, followed by campesterol, <sub>5</sub>-avenasterol, stigmasterol and <sub>7</sub>-stigmasterol. Total sterol content increased and decreased with ripening in <em>Futura 75</em> and <em>Carmagnola</em>, respectively. The study confirms that ripening stage affects the quality of hempseed oil, important parameter to consider for hemp seed producers.</p> S. MARZOCCHI, M.F.
