title: Row orientation effects on chemical composition and aromatic profile of Syrah winter wines

description: Abstract Sunlight and heating influence leaf and grape metabolism and therefore wine quality. As a recent management tool, no information exists on the effects of grapevine row orientation on the wine composition of Syrah vines within the context of double pruning management, a technique used to transfer the grape harvest from the wet summer to the dry winter season. This is a first attempt to investigate the wine composition from north-south- (NS) and east-west- (EW) oriented Syrah winter vines. EW wine samples had higher total acidity, residual sugars, alcohol and color hue, whereas NS wines exhibited higher content of color intensity, anthocyanins, total phenolics, total phenolic index, ashes and pH. The identification of volatile compounds was tentatively performed and demonstrated the presence of alkanes, volatile phenols and alkyl sulfide in NS wines, while butyrolactone and beta-damascenone were found mainly in EW wines. Row orientation contributed to wine composition and could be used as a management tool for obtaining individual wine styles.

title: Obesity-associated Pathways of Anthocyanins

description: Abstract Anthocyanins have a great potential for human health, as a sub-group of phenolic compounds. Interactions of anthocyanin involved in digestion and thus in obesity consist of inhibition of pancreatic lipase, regulation of lipolysis and lipogenesis, activation of an activated protein kinase enzyme, controlling of digestion hormones (leptin, insulin, ghrelin, cholecystokinin, GIP, GLP-1). Anthocyanins are the compounds that can control metabolic syndrome and obesity by ameliorating lipid metabolism, increasing energy expenditure, suppressing food intake and inhibiting lipid absorption. In addition, the interactions with other compounds during the processing and/or in the intestinal canal can change their absorption capability and bioavailability. Activation of mitogen-activated protein kinase and cyclooxygenase (COX) enzymes, inflammatory cytokines signaling, free-radical scavenging activity are among the primary functions of anthocyanins playing role in the basic metabolic pathways. Anthocyanins also interact with gut microbiota that plays a role in many metabolic pathways. In the review, the effects of anthocyanins on the obesity-associated mechanisms in the metabolism are considered and summarized under the light of recent researches.

title: Modeling mass transfer during osmotic dehydration of different vegetable structures under vacuum conditions

description: Abstract Osmotic dehydration (OD) is a method to partially reduce moisture of food, aiming to improve the shelf life and the stability of the products. The mass transfer that occurs during this process can be enhanced with the application of reduced pressure in the first minutes of the osmotic dehydration (pulsed vacuum osmotic dehydration - PVOD). The present work aimed to study the vacuum effect on the kinetics of osmotic dehydration of vegetables (carrot, eggplant and beetroot) in terms of water loss, solids gain and water activity, in ternary solution. Moreover, mathematical modeling of experimental data obtained from the osmotic processes, was employed for correlating the mass transfer of the food product under the different conditions. An intensification of mass transfer was observed for carrot and eggplant in the vacuum treatments. This was related to their porous structure. The present work demonstrated a lack of fit of Fick’s second law for describing the dehydration kinetics of the eggplant.

title: Qualitative properties of cookies enriched with berries pomace

description: Abstract The purpose of this study was to investigate the qualitative properties of cookies with the addition of raspberry, red currants and strawberry pomace flour. Cookies were prepared by substitution of wheat flour with berry pomace flour (10%, 15% and 20%) and evaluated in terms of their proximate composition, physical characteristics, and functional and sensory properties. Berry pomace-supplemented cookies had significantly higher dietary fibre content and different fibre fractions NDF (neutral detergent fibre), ADF (acid detergent fibre), MADF (insoluble fibre fraction of modified acid detergent solution) as well as WSCs (water soluble carbohydrates) content. Correlation analysis results showed that cookie hardness was significantly correlated with dietary fibre content. The raspberry, red currant and strawberry flours contained 49.88%, 33.13% and 24.25% of dietary fibre, respectively. The colour of the cookies was measured using a Color Flex spectrophotometer. The average L*, a*, and b* values ranged from 37.35 to 68.29, from 7.08 to 13.18, and from 20.12 to 34.73, respectively.

title: Investigation of Listeria monocytogenes in workers, equipment and environments at Kaymak processing plants

description: Abstract Listeria monocytogenes is a nutrient-borne pathogen spread to processed products such as vegetables, fruits and dairy products. Especially in the dairy industry, the presence of L. monocytogenes poses a major problem in milk, dairy products and dairy plants. Infection caused by this bacterium is a serious threat to individuals such as immunosuppressed patients, newborns, the elderly and pregnant women. In this study, the presence of L. monocytogenes in Afyonkarahisar/Turkey in the samples taken from plants that produce three different kaymak types was investigated. For this purpose, a total of 87 samples taken from the kaymak production plant, the surfaces of the equipment in this plant and the employees were examined according to the ISO 11290-1 protocol. According to the results of our study, L. monocytogenes was detected in 8.33% of the 36 samples taken from the processing plant and 16.66% of the total of 24 pieces of equipment in the processing plant. L. monocytogenes was not detected in the workers’ hands, aprons or boots at all three plants. When the results obtained are interpreted, it is understood that this may pose a significant risk to public health if the necessary precautions are not taken in production of cream.

title: Synergistic effects of unripe raspberry extracts (Rubus chingii) and antibiotics against three bacteria

description: Abstract Dried unripe raspberries (Rubus chingii), a kind of Chinese herbal medicine, have been used for many years in China. They were prepared as unpurified raspberry extract (URE) by ethanol extraction, and purified raspberry extract (PRE) by macroporous resin. Synergistic effects between the URE (or the PRE) and ampicillin, erythromycin, tetracycline or streptomycin against Escherichia coli, Staphylococcus aureus and Salmonella enterica were carried out using checkerboard microdilution and time-kill curves, respectively. The results showed that all pairwise combinations revealed synergistic effects, with 0.10 ≤ fractional inhibitory concentration index ≤ 0.50 and more than 2 × log10 reduction in colony-forming units/mL. In particular, the erythromycin concentration in the combinations was reduced to 1/50-1/100 of its dose alone while retaining its effectiveness against S. aureus and E. coli. The synergistic effects of raspberry extracts and four antibiotics against three bacteria were related to the abundance of polyphenols in the extracts, especially ellagic acid. The extracts may be a dietary supplement and/or natural antimicrobials.

title: Physical and sensory characteristics of salty cereal bar with different binding agents

description: Abstract The purpose of this study was to evaluate different binding agents for the preparation of salty cereal bars and to characterize them regarding their physical and sensory parameters. Four formulations of cereal bars were developed using collagen, guar gum, xanthan gum and psyllium as binders, which were evaluated for instrumental color and texture. The results of the instrumental analysis revealed that the cereal bars presented characteristic color and crispness for this type of product and the microbiological analyzes ensured food safety. Sensorially, the cereal bars showed good acceptability, especially the bars made with psyllium and xanthan gum binders in the parameters of appearance, texture, flavor and color. The different binders showed technological efficiency in the elaboration of salty cereal bars, but xanthan gum and psyllium were the ones that best corresponded to the expected attributes.

title: Comparative assessment of antioxidant activity and biochemical composition of four seaweeds, Rocky Bay of Abu Qir in Alexandria, Egypt

description: Abstract The current study estimated the antioxidant activity and biochemical composition of four seaweeds; Toania atomaria (Phaeophyta), Padina pavonia (Phaeophyta), Jania rubens (Rhodophyta) and Corallina elongate (Rhodophyta). The highest total antioxidant activity was observed with ethanol extract of T. atomaria (44.6 ± 1.6 mg ascorbic acid equivalents/g crude extract). Among the four seaweeds, ethanol extract of T. atomaria has recorded the highest value in ferric reducing antioxidant power (FRAP) assay (32.3 ± 0.0 mg ascorbic acid equivalents/g crude extract). The uppermost level of carbohydrates was (20.4% ± 0.4 and 19.5% ± 0.7 dry wt.) in P. pavonia and T. atomaria. Proteins were maximum (10.5% ± 0.6 and 8.0% ± 0.0 dry wt.) in P. pavonia and T. atomaria. The results detected that T. atomaria had the largest amounts of lipids (5.92% ± 0.09 dry wt.). The polyunsaturated ω6 essential fatty acids were recorded in T.atomaria, P. pavonia, and J. rubens (11.39%, 8.09%, and 6.28%), and ω3 essential fatty acids were recorded in T. atomaria and P. pavonia (0.65% and 0.97%). The seaweeds are interesting candidates for medicinal, pharmaceutical, and nutritional applications owing to their antioxidant activities, biochemical composition; they are not widespread in the coastal waters of Egypt and has few studies, especially T. atomaria.

title: In-vitro bioaccessibility of antioxidant properties of bee pollen in Turkey

description: Abstract The study aims to determine certain physicochemical properties (moisture, ash, titratable acidity, pH, and color), total phenolic content, antioxidant capacity (CUPRAC, ABTS, DPPH) and bioaccessibility of 20 bee pollen samples (10 unpackaged and 10 trademarked products in their original packages) sold in Turkey. The total phenolic content of the bee pollen samples was detected as 147.10-462.02 mg GAE/g and bioaccessibility ranged from 36.91% to 77.87%. The highest total value for antioxidant capacity was assessed as 83.24-257.27 μmol TE/g by the CUPRAC method. When the bioaccessibility of the antioxidant capacity of bee pollen was compared among the methods, the highest value (95.76%) was obtained for the sample M by the CUPRAC method. Antioxidant capacity and bioaccessibility of the unpackaged bee pollen samples were lower than those of the trademarked products. Based on overall evaluations, it can be deduced that bee pollen known for its potential beneficial effects on health may well be used as a functional food additive in the production of various food products with its high antioxidant and bioaccessibility features.

title: Production of a novel probiotic date juice with anti-proliferative activity against Hep-2 cancer cells

description: Abstract Date fruit is the ancient discovered and consumed fruit. Worldwide, Egypt is the largest producer of date. Besides its health benefits, many recent studies have proved its antioxidant, anticancer and anti-inflammatory effect. Currently, probiotic fermented fruit juices have a great attention especially for lactose intolerance patients. This study assessed the survival of two probiotics (Lactobacillus acidophilus and L. sakei) in the date juice. Phenolics characterization was performed by HPLC. Anti-proliferative activity of fermented juice against Caco-2 and Hep-2 cell lines was also evaluated. Under cold storage, L. sakei was still live for 2 weeks at 1.8 x 107 CFU/mL. In contrast, L. acidophilus reduced from 5.2 x 106 CFU/mL to below the minimum value of probiotic products just after 1 week. L. sakie significantly multiplied the total phenols and antioxidant activity in the juice compared to the unfermented juice. Interestingly, probiotic date juice exhibited an antitumor activity against larynx cell lines (Hep-2) with no activity against Caco-2. Date juice was proved to be suitable for probiotic and as potential larynx anticancer juice. Therefore, the developed juice is recommended to contribute to the available probiotic foodstuffs.
