Título : Biological activity, antioxidant capacity and volatile profile of enriched Slovak chocolates Autor : Godočiková, Lucia; Ivanišová, Eva; Noguera Artiaga, Luis; Carbonell Barrachina, Ángel A.; Kačániová, Miroslava Resumen : Different kinds and types of chocolates produced in Slovakia with various fruit and nut enrichments were analysed regarding total polyphenols, flavonoids and phenolic acids contents using spectrophotometric methods and their volatile profile was analysed using gas chromatography–mass spectrometry. The method with 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing power method (FRAP) were used to measure antioxidant activity. Plain dark chocolate without any enrichment made by a traditional process contained the highest number of total polyphenols and phenolic acids and also had the highest antioxidant activity. Positive correlation was observed between antioxidant activity and total contents of phenolic compounds, flavonoids and phenolic acids. The enrichment with different kinds of fruits did not increase the number of bioactive compounds or antioxidant capacity of chocolates but created more attractive sensory profiles due to the presence of new volatile compounds.

Título : Antioxidant, antihemolysis, and retinoprotective potentials of bioactive lipidiccompounds from wild shrimp (Litopenaeus stylirostris) muscle Autor : García Romo, Joel Said; Noguera Artiaga, Luis; Gálvez Iriqui, Alma Carolina; Hernández Zazueta, Martin Samuel; Valenzuela Cota, Daniel Fernando; González Vega, Ricardo Iván; Plascencia Jatomea, Maribel; Burboa Zazueta, María Guadalupe; Sandoval Petris, Edgar; Robles Sánchez, Rosario Maribel; Juárez, Josué; Hernández Martínez, Javier; Santacruz Ortega, Hisila del Carmen; Burgos Hernández, Armando Resumen : The oxidative stress damage on cells is an example of roles in the pathogenesis of differentdegenerative diseases and the search of compounds that can slow this oxidation is continuous.The aim of this work was to obtain bioactive fractions from wild shrimp (Litopenaeus stylirostris)muscle, in order to evaluate their protective capacity and chemo-structurally characterize them.ABTS and DPPH, and FRAP assays suggested that bioactive fractions possess free radical-scavengingcapacity, and reducing power, respectively. An inhibitory effect observed on AAPH-induced hemo-lysis and results from an H2O 2-derived radicals-scavenging assay (retinoprotective) suggest thatthese fractions can exert their protective activity in human cells. UV–Vis, fluorescence, 13C-, 1H-NMR,and ESI-MS studies performed on the most bioactive fraction, suggests that their main componentsare eicosapentaenoic acid, dioctyl phthalate, and a possibly novel indolocarbazole alkaloid deriva-tive. These results suggest that these compounds are good candidates to further investigations aspossible chemoprotective agents.

Título : Functional and sensory properties of pistachio nuts as affected by cultivar Autor : Noguera Artiaga, Luis; Salvador, María D; Fregapane, Giuseppe; Collado González, Jacinta; Wojdyło, Aneta; López Lluch, David; Carbonell Barrachina, Ángel A Resumen : BACKGROUND Modern agriculture allows farmers to choose among different cultivars of the same fruit to fulfill their agronomic needs and consumers' demands; however, there are only a few studies that describe and compare key functional and sensory properties of different pistachio cultivars. The main objective of this study was to compare eight pistachio cultivars by analyzing key functional properties (phenolic compounds, polymeric procyanidins, antioxidant activity, and inhibition of α-amylase and β-glucosidase), aromatic compounds with gas chromatography–mass spectrometry (GC–MS), and by examining their sensory properties with a trained panel. RESULTS A combination of LC-PDA-MS-QTof (liquid chromatography photodiode array quadrupole time-off flight mass spectrometry) and electrospray ionization was used to determine two phenolic acids, nine flavonols, one anthocyanin, and three flavan-3-ols in pistachio cultivars, with a total concentration ranging from 500 to 6065 mg 100 g−1 dry weight (dw). The total polymeric procyanidins concentrations oscillated between 348 and 5919 mg 100 g−1 dw, (−)-epicatechin being the major monomer contributor. Pinene was the most abundant volatile compound (∼200 mg kg−1 dw), and, in the sensory analysis of samples, 23 sensory attributes were found to differ significantly among the cultivars. CONCLUSION The cultivar ‘Larnaka’ stood out as having the best functional profile (high polyphenolic content, high antioxidant activity, and high values of α-amylase and β-glucosidase inhibition), and the cultivars ‘Kastel’ and ‘Kerman’ showed the most attractive sensory properties, mainly the most intense flavor. © 2019 Society of Chemical Industry

Título : Sensory and physico-chemical quality attributes of jujube fruits as affected by crop load Autor : Galindo, Alejandro; Noguera Artiaga, Luis; Cruz, Zulma N.; Burlo, Francisco; Hernández, Francisca; Torrecillas, Arturo; Carbonell Barrachina, Ángel A. Resumen : No information exists on the overall quality attributes of jujube fruits as influenced by crop load; besides, there are no studies describing the sensory profile of this fruit. For this reason, the aim of this study was to analyze the influence of the reduction of crop load (T1: one third of the crop load was removed; T2: two thirds of the crop load were removed) on the quality of jujube fruits. The quality parameters studied were: yield, fruit morphology, color, instrumental texture, minerals, volatile composition, and sensory profile. Results have demonstrated that reduction of crop load increased: (i) the intensity of characteristic sensory attributes of jujube fruits, such as sweetness, sourness, jujube-like, or fruity notes, and (ii) the contents of some volatile compounds, such as trans-2-hexenal, benzaldehyde, and 2-octenal, which are characterized by fruity notes. However, a reduction of crop load did not significantly affect any of the morphological parameters under study. Thus, the reduction of crop load increased the overall quality (intensity of key sensory attributes, and content of key volatile compounds) of jujube fruits.

Título : Preharvest treatments with malic, oxalic, and acetylsalicylic acids affect the phenolic composition and antioxidant capacity of coriander, dill and parsley Autor : El-Zaeddi, Hussein; Calín Sánchez, Ángel; Nowicka, Paulina; Martínez Tomé, Juan; Noguera Artiaga, Luis; Burló, Francisco; Wojdyło, Aneta; Carbonell Barrachina, Ángel A. Resumen : The effects of a preharvest treatment with malic (MA), oxalic (OA), or acetylsalicylic (ASA) acid at three concentrations (1, 2 and 3 mM) on the bioactivity and antioxidant capacity of coriander, dill, and parsley were investigated. The antioxidant capacity of the herbs extracts was assayed by spectrophotometric methods by using three different analytical methods: ORAC, FRAP, and ABTS; the effects of treatments were very positive in coriander, produced intermediate results in dill, and no effects were found in parsley plants. Polyphenol compounds were identified by LC-MS-QTof and quantified by UPLC-PDA-FL. Thirty phenolic compounds were identified in these three herbs. The major compounds were (i) coriander: dimethoxycinnamoyl hexoside and quercetin-3-O-rutinoside, (ii) dill: neochlorogenic acid and quercetin glucuronide, and (iii) parsley: apigenin-7-apiosylglucoside (apiin) and isorhamnetin-3-O-hexoside. The application of these three organic acids favored the accumulation of phenolic compounds in coriander plants, but had no significant positive effects on dill and parsley. The treatments leading to the best results in all three plants were the application of MA or OA at 1 mM.

Título : Irrigation dose and plant density affect the essential oil content and sensory quality of parsley (Petroselinum sativum) Autor : El-Zaeddi, Hussein; Calín Sánchez, Ángel; Martínez Tomé, Juan; Noguera Artiaga, Luis; Burló, Francisco; Carbonell Barrachina, Ángel A. Resumen : In the current study the influence of 3 irrigation treatments (ID0 as a control, ID1, and ID2), and 3 plant density treatments (PD0 as a control, PD1, and PD2) were investigated on the production (total yield), volatile composition of essential oil, and sensory quality of parsley (Petroselinum sativum). The results showed that the highest plant yield was obtained when using the highest values of both irrigation dose (ID2 = 1788 m3 ha−1) and plant density (PD2 = 7.41 plants m−2). Hydrodistillation technique was used to extract the essential oil of parsley shoots and GC–MS and GC-FID were used to identify and quantify the components of the essential oil, respectively. The results showed that the main compounds of the essential oil were β-phellandrene, 1,3,8-p-menthatriene, myristicin, myrcene, terpinolene, limonene, α-pinene, and α-phellandrene. The treatment ID1 (861 m3 ha−1) led to the highest concentrations of most of the main compounds: 1,3,8-p-menthatriene (150 mg kg−1), myristicin (46.8 mg kg−1), and myrcene (33.7 mg kg−1); a similar pattern was found for the plant density PD0 (5.56 plants m−2), with contents being 1,3,8-p-menthatriene (143 mg kg−1), β-phellandrene (130 mg kg−1), and myristicin (38.1 mg kg−1). Aroma attributes, such as parsley-like, citrus, and green grass significantly had the highest intensities in ID1 and PD0 plants. The final recommendation based on all data generated is to use the irrigation dose of 861 m3 ha−1 (ID1) and the plant density of 5.56 plants m−2 (PD0) for better yield and quality of the final product under the assayed conditions.

Título : Comprehensive Analysis of Chlorella vulgaris and Arthrospira platensis: Algae for Food Well-Being and Sustainable Agriculture Autor : Čmiková, Natália; Vukić, Milena D.; Vukovic, Nenad L.; Havlík, Jaroslav; Noguera Artiaga, Luis; Carbonell Barrachina, Ángel A.; Jančo, Ivona; Vinciguerra, Vittorio; Garzoli, Stefania; Kačániová, Miroslava Resumen : This study investigates the nutritional and bioactive properties of Chlorella vulgaris (chlorella) and Arthrospira platensis (spirulina) to explore their potential applications in food sector and sustainable agriculture. The study involved comprehensive metabolite profiling using nuclear magnetic resonance (NMR) spectroscopy, analysis of volatile organic compounds via gas chromatography (GC), and carotenoid quantification through high-performance liquid chromatography (HPLC). Risk elements and mineral content were determined using inductively coupled plasma (ICP) analysis, while the fatty acid profile was assessed by gas chromatography−mass spectrometry (GC−MS). Antioxidant activity was evaluated using DPPH and ABTS assays. The antimicrobial potential was assessed using disc diffusion and minimum inhibitory concentration (MIC) methods, along with antibiofilm activity tested against plant phytopathogens. Results showed that C. vulgaris contains high levels of sucrose (18.47 mg/g), while A. platensis has elevated glutamate (7.73 mg/g) and lactate (3.65 mg/g). The volatile compound analysis of C. vulgaris and A. platensis showed that both algae are predominantly composed of alcohols, C. vulgaris 63.56% and A. platensis 60.81%. A. platensis exhibited superior antioxidant efficacy compared to C. vulgaris. Both algae showed the largest zones of inhibition against Xanthomonas arboricola and the filamentous fungus Monilia fructigena. In addition, both species showed strong antibiofilm activity against P. megaterium. The results indicate that both algae are rich in valuable bioactive compounds with potential applications in sustainable agriculture and food production. Extracts from C. vulgaris and A. platensis demonstrated promising antimicrobial and antioxidant properties, highlighting their potential as natural biocontrol agents and alternatives to synthetic pesticides and additives. Their incorporation into agricultural systems could help reduce environmental impact and support the development of more sustainable food systems.

Título : Effects of two rootstocks (Pistacia Vera L. and Pistacia Atlantica Desf.) on the yield, morphology, chemical composition, and functional properties of two pistachio varieties ("mateur" and "Achoury") Autor : Ouni, Samiha; Chelli-Chaabouni, Azza; Noguera-Artiaga, Luis; Hernández, Francisca; Ben-Hamda, Hmida; Ouerghui, Imen; Carbonell-Barrachina, Ángel A.; Rhouma, Ali Resumen : The low diversification of rootstocks can be a problem in reducing the adaptation of pistachio to the Tunisian climatic and soil conditions. Nowadays, the most used rootstock is Pistacia vera; however, the autochthonous Pistacia atlantica could be a good alternative.The aim of this work was to study the effect of two different rootstocks Pistacia veraand Pistacia atlanticaon the quality and functionality of two pistachio cultivars (the local variety “Mateur” and the Syrian one “Achoury”). The different parameters studied were: morphological (size, weight), chemical (minerals and fatty acids) and functional (total phenolic content, and antioxidant activity: ABTS+, DPPH•, and FRAP). The pistachios are a good source of minerals (especially Ca and K 19.9 and9.8 g kg-1, respectively, and Fe 54.5 mg kg-1), polyunsaturated fatty acids (oleic and linoleic acids), and phenolic compounds (16.0 g GAE kg-1). The combination P. atlanticaand variety “Mateur” led to proper values of tree yield, nut dehiscence, morphology (length and width), and oleic acid content. Thus, it can be concluded that the use of the local rootstock P. atlanticaled to promising results and can be a good option due to its higher adaptation to the local climatic and soil conditions.

Título : Chemical composition, mineral content and antioxidant capacity of phenolic extracts and essential oils of Lavandula stoechas L. Autor : Asmaa, Noureddine; Abdelaziz, Gherib; Boulanouar, Bakchiche; Carbonell-Barrachina, Ángel Antonio; Cano-Lamadrid, Marina; Noguera-Artiaga, Luis Resumen : Lavandula stoechas L. from the west of Algeria were analyzed for their chemical composition, mineral content, total phenol and flavonoid contents, and also the antioxidant activity of the essential oils and methanol extract. Many essential minerals including potassium, magnesium, sodium and trace elements, such as iron, zinc, copper and manganese were determined. The total phenol and flavonoid contents in Lavandula stoechas were determined spectrophotometrically as 9.74 mg ± 0.48 gallic acid equivalents / gram of plant, and 4.615 mg ± 0.18 rutin equivalents / gram of plant for polyphenols and flavonoids respectively. The essential oils extracted by water distillation leads to extract 1.36 % dw, its composition identified by the GC-MS analysis was characterized by high proportions of α-fenchone (39.0 %), camphor (18.5 %), bornyl acetate (7.79 %), viridiflorol (4.55 %), and myrtenyl acetate (3.32 %). Our results show, in all tests of antioxidant capacity, that methanol extract has power to scavenging free radicals and reducing metals, better than Lavandula stoechas essential oils.
