title: Trace analysis of environmental endocrine disrupting contaminant bisphenol A in canned, glass and polyethylene terephthalate plastic carbonated beverages of diverse flavors and origin

description: Abstract Bisphenol A (BPA) is a hazardous contaminant demonstrating endocrine disrupting properties, and assumed to be involved in the pathogenesis of various cancer diseases for instance prostate, lung and breast cancer. The objective of the present study was to estimate the BPA amounts in carbonated beverages from the Saudi Arabian market for the first time using an authenticated technique based on solid-phase extraction and ultra-performance liquid chromatography-tandem mass spectrometry. A total of thirty-four carbonated beverages of different flavors, origin and packaging materials were studied. The beverage production periods were from February 2018 to July 2018 containing volume (250-1000 mL), packaging materials were of canned, glass and polyethylene terephthalate (PET) plastic. BPA amounts in canned (0.64-11.41 µg/L), glass bottled (1.92-29.56 µg/L) and PET plastic bottled (0.37-21.83 µg/L) were obtained with recovery (97.64-99.96%). Relatively, glass bottled has offered higher amounts of BPA compared to PET plastic bottled and canned samples. The unforeseen presence of BPA especially in glass bottled emphasizes the ubiquity of such compound beside the food fabrication chain, far off to the food packaging materials. Thus, a further knowledge on BPA amounts in glass bottled samples, in addition to threat assessment studies, is essential to defend human health.

title: Investigation of ultrasound pretreatment time and microwave power level on drying and rehydration kinetics of green olives

description: Abstract In this study, the effect of ultrasound (US) combined microwave (MW) drying of green olive slices was studied. Olive samples were exposed to ultrasound (5 and 10 minutes; 32 KHz) at room temperature before dried at microwave at 3 different power level (180W, 450 W and 800 W). The drying and rehydration characteristics and quality parameters of olives were determined by comparing with obtained by non-ultrasound pretreated MW dried samples. Midilli et al and Diffusion models were the most suitable models for US-MW drying with the highest R2, and lowest RMSE and chi square values. Total phenolic compounds (TPC) of olive slices reduced during drying in all treatments, however TPC of ultrasound pretreated samples were relatively higher those non treated samples dried at same microwave. Increasing of microwave level and ultrasound time decreased the total drying time up to B.5. This study showed that US-MW can be a useful combine drying method for olive slices which decreased the drying time and improved the qualitative properties of olives.

title: Increase in conjugated linoleic acid content and improvement in microbial and physicochemical properties of a novel kefir stored at refrigerated temperature using complementary probiotics and prebiotic

description: Abstract The present study was aimed to determine the effects of Lactobacillus acidophilus LA-5, L. paracasei 431, and Bifidobacterium lactis BB-12 with lactulose on values of conjugated linoleic acid (CLA) and microbial, physicochemical, and sensory properties of a novel kefir. Thirteen groups were evaluated on days 1, 7, and 14 at 4 oC. The interaction between probiotics and lactulose reduced pH to 4.5 in the first week and slightly decreased on day 14 (4.35). The syneresis value was decreased by increasing the lactulose dose. The interaction could not remarkably increase probiotic survival; the greatest and lowest values were 7.18 and 7.81 log CFU/mL, respectively. The greatest and the lowest lactic acid value was 2.77 and 1.47 g/100 mL, respectively, in kefirs supplemented with L. acidophilus LA-5 and L. acidophilus LA-5+ L. paracasei 431+ B. lactis BB-12. A 4-fold increase in the acetic acid value (0.592 g/100 mL) was observed in kefirs supplemented with B. lactis BB-12 along with L. acidophilus LA-5 and L. paracasei 431 (G12). It is concluded that adding 5% lactulose along with L. acidophilus LA-5+ L. paracasei 431 to kefir could valuably increase the CLA value (3.51-8.07 ppm) and give it more acceptability of flavor, odor, and syneresis.

title: Influence of roasted and unroasted terebinth (Pistacia terebinthus) on the functional, chemical and textural properties of wire-cut cookies

description: Abstract The study aimed to access the effects of roasted and unroasted terebinth (0, 10, 20, 30, 40, and 50%) added to cookies to improve their physical, chemical, functional, and textural characteristics. The addition of terebinth to the cookie formulation significantly increased the ash, protein, fat, total dietary fiber, total phenolic matter, and antioxidant content and decreased the phytic acid content of the cookie samples. With the addition of roasted and unroasted terebinth, it was determined that L*, b* values of cookies decreased, a* value increased, and all color values were lower than control group. In addition, it was found that the diameter and thickness values of cookies with terebinth addition decreased, and the spread ratio increased. The hardness of cookies produced in the study decreased after terebinth addition. The data obtained in this study showed that using terebinth has potential applications in baked goods without adverse effects on the physical and chemical quality or the functional quality of the product.

title: Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage

description: Abstract The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate the freshness of Oncorhynchus mykiss fillets during 14 days at the refrigerated temperature. The 160 pieces of fish were enfolded in 4 types of films as main group-series. The main components of the extract were carvacrol (83.2%) p-cymene (3.11%), thymol (2.13%) and γ-terpinene (1.63%). The UV-Vis and TEM evaluations of S-AgNPs showed that the size of S-AgNPs was mostly smaller than 55 nm in diameter. Mesophilic and psychrophilic bacteria counts were remarkably less than 6.0 log CFU/g about 2.1, 1.3 log CFU/g and 2.0, 1.0 log CFU/g, respectively for fish samples wrapped in S-AgNP/Ult.PVA (Ultrasound method) and S-AgNP/Pho.PVA (Photochemical method) preserved at 4 °C on the 7th day. S-AgNP/Ult.PVA and S-AgNP/Pho.PVA showed strong efficiency in complete eliminating S. aureus and psychrophilic bacteria from coated trout samples than E. coli and mesophiles. It is suggested that AgNP/Ult.PVA and S-AgNP/Pho.PVA films can be used as nanocomposite film for fish preservation at refrigerated temperature to postpone the spoilage up to 7th day.

title: Effect of part-baking time, freezing rate and storage time on part-baked bread quality

description: Abstract In the baking industry, different processes and methods of freezing have been used for breadmaking to preserve a quality comparable to that of fresh bread. In this study, the effect of part-baking time, freezing rate, and frozen storage time on part-baked French bread quality was determined. The bread was part-baked for 0, 3 and 6 min, frozen at slow (0.15 °C/min) and fast (1.75 °C/min) freezing rates, stored under freezing conditions for up to 56 days and thawed every 14 days. Part-baked bread was rebaked, and the SV and firmness at 2, 24 and 48 h were obtained. An experiment with a factorial design of 3×2×5 (3 part-baking time, 2 freezing rates and 5 frozen storage times) with analysis of variance (ANOVA) at a confidence level of 95% was carried out. The highest SV was obtained at 6 min of part-baking at a slow freezing rate and decreased as the frozen storage time increased. In contrast, TPA showed that bread firmness increases when the specific volume decreases, and the highest firmness is at 0 min of part-baked time. Relatively long part-baking times allow for firm crumb formation with limited damage to the structure and therefore bread with optimal quality.

title: Direct steam injection pretreatment improves microwave-assisted extraction yield for total flavonoids and myricetin from Hovenia dulcis Thunb.

description: Abstract A direct steam injection pretreatment was added before the microwave-assisted extraction procedure for the extraction of flavonoids from seeds of Hovenia dulcis Thunb, and the antioxidant activity of flavonoid extracts was determined. Based on the experimental results, the addition of direct steam injection simultaneously increased the extraction yield of total flavonoids compared with direct microwave-assisted extraction, and antioxidant activity of flavonoid extracts obtained by adopting the steam injection pretreatment was higher than that by direct microwave extraction alone. Myricetin was isolated from the flavonoid extracts, and the structure was identified by infrared spectroscopy (IR), electrospray ionization mass spectrometry (ESI-MS), and 1H nuclear magnetic resonance (1H-NMR). Recovery yield of total flavonoids was increased by 11.63% when the direct steam injection pretreatment was added to direct microwave extraction.

title: A meta-analysis: association between Beta-2 adrenergic receptor Arg16Gly polymorphism and asthma in China

description: Abstract For different populations, the association studies between the beta-2 adrenergic receptor (ADRB2) Arg16Gly mutation and asthma are conflict. This study was designated to evaluate ADRB2 Arg16Gly polymorphism and asthma in Chinese population. Systemic assessment was performed based on the data from PubMed, Embase, Web of Science, the Cochrane Library, and Chinese National Knowledge Infrastructure (CNKI) up to January 2019. Odds ratios (ORs) with their 95% confidence intervals (95% CIs) were calculated using STATA software. This meta-analysis included 6143 asthma patients and 5919 healthy persons from 34 studies. Overall, ADRB2 Arg16Gly polymorphism showed no significant influence on asthma in China. However, subgroup analyses according to geographic areas, age group and HWE in controls, only found a borderline significant effect for southern Chinese under the homozygotes genetic model (OR = 0.82, 95%CI = 0.68-1.00, P = 0.046). This meta-analysis suggests that ADRB2 Arg16Gly polymorphism is not be related to the development of asthma in China.

title: Hypocholesterolemic effect of designer yogurts fortified with omega fatty acids and dietary fibers in hypercholesterolemic subjects

description: Abstract A cohort study of 90 days was designed to explore the hypercholesterolemic associated blood pressure with intake of extruded flaxseed powder (EFSP) fortified yogurts. The hypercholesterolemic subjects were distributed into two groups (1 and 2), then blood samples and blood pressure were taken. Descriptive statistics were used for comparison between groups. A significant increase in serum total cholesterol (TC) (6.330.48 to 6.510.04 mmol/dL) and low-density lipids-cholesterol (LDL-C) (5.170.28 to 5.370.47 mmol/dL) was observed in participants consuming plain milk yogurts for 30 days. A significant decrease in TC (6.470.95 to 6.28 ± 0.84) and LDL-C (5.350.29 to 5.130.44 mmol/dL) was observed in the group consuming EFSP fortified sheep milk yogurt. Similarly, a significant decrease in serum TC (6.381.01 to 6.200.98 mmol/dL), and LDL-C (5.301.16 to 4.980.99 mmol/dL) was noticed in the group consuming EFSP fortified cow milk yogurt. The intake of fortified yogurts reduced significantly serum cholesterol associated with blood pressure in both groups.

title: Properties and characterization of biodegradable films obtained from different starch sources

description: Abstract The increasing use of natural biodegradable polymers to preserve foods is a consequence of the concern of society with sustainability. Starch stands out amongst the natural polymers due to its great availability on a worldwide scale, high extraction yield and nutritional value, low cost, biodegradability and biocompatibility. Apart from the traditional sources, various others exist with extraction potential. The objective of this study was to identify films from different non-traditional starch sources with properties revealing their potential to be applied as coating for fruits and vegetables. The biodegradable films were prepared with three starch concentrations (2, 3 and 3.5%) for each of the following sources: cassava, yam, jackfruit seed and mango kernel. The starches from the sources studied are promising ingredients for the formulation of films, presenting good physical, optical (such as transparency) and mechanical characteristics, principally tensile strength whose maximum value was 36.63 MPa. Increases in starch concentration directly influenced the thickness, water vapor permeability, tensile strength and puncture force. The films with the greatest potentials for use according to their characteristics were 3% cassava, 3% yam, 3.5% jackfruit seed and 2% mango.
