title: Effects of Lactobacillus used as the starter culture on naturally fermented pickled cabbage

description: Abstract Pickled cabbage is a traditional and typical fermented food, which occurs as a result of fermentation of bacteria that exist in the medium naturally. In this study, the effects of Lactobacillus plantarum, Lactobacillus pentosus and Lactobacillus paraplantarum on the pickled cabbage fermentation were investigated. The physicochemical (total acidity, salt and pH) and microbiological (lactic acid bacteria, total mesophilic aerobic bacteria and yeast-mould) changes that occurred during the fermentation were observed. In addition, the amounts of biogenic amine (BA) and metabolites were determined with HPLC. It was found that the amount of acidity (%) was lower in Lactobacillus samples. Important microbiological changes were observed in the L. plantarum 46 and L. pentosus samples. The total BA amount was found to be the lowest for the sample L. plantarum 61. It was also seen that the BA was less than any poisonous rate affecting the human health. On day 60 of fermentation, the amount of metabolite was maximum in the L. plantarum 61and L. paraplantarum samples. As a result, the total amount of BA was observed to be lowest in the L. plantarum 61 sample inoculated with L. plantarum 61 culture and in the metabolites synthesized highly. It is suggested that the use of such Lactobacillus for the natural pickle process will allows for the production of a tastier and more reliable product, contributing to the food industry.

title: Assessment of the caffeine-containing beverages available in the local markets, and development of a real energy drink based on the date fruit

description: Abstract Globally, tea, coffee, soft and energy drinks are daily consumed as a source of caffeine. Energy drinks gained a great public and scientific issues, thus this study assessed the caffeine content in some caffeine-containing beverages. Given the increasing demand for newly formulated healthy drinks, the date fruit (Phoenix dactylifera L. cv. Siwi) was used to develop a fruit-energy drink as an alternative for the energy drinks. Results displayed that the coffee addition even to 80 mg/250 mL, did not significantly altered the acidity of the final developed drink. It contained rapidly metabolized sugars of 27.86 g/250 mL without added sugar and was slightly neutral (pH = 6.04). The sensory assessment revealed that the added coffee (up to 320 mg/L) enhanced its aroma and taste but negatively affected the color. The high naturally occurring vitamins and minerals content and the gross energy; made this drink a super energy drink to fulfill the needs of athletes. Some of the tested local caffeine-containing beverages contained caffeine higher than those mentioned on the product label. On the other side, Turkish coffee brews contained 1.99-9.46 mg/g and the instant coffees had provided the highest ever caffeine (24.71 mg/g), such that their daily consumption should be alarmed.

title: Effect of proteasome inhibitor MG132 on the expression of oxidative metabolism related genes in tomato

description: Abstract Expression analysis of antioxidant related genes may provide key information to develop plants more tolerant to abiotic and biotic stress. For this purpose, in this study, proteosome was inhibited by using MG132 proteosome inhibitor in Lycopersicon esculentum (tomato) tissues with high antioxidant content. We aimed to explain the response of gene isoforms associated with oxidative stress metabolism as a result of proteasome inhibition induced by MG132 in tomato. Gene expression levels of SLGR1, SLPhGPX, SLCAT1, SLFe-SOD, SLGPX, SLCu/Zn-SOD, SLcAPX and SLGST genes which are known to be associated with antioxidant mechanisms, were determined by real-time PCR in tomato. There was no significant change in SLPhGPX, SLCAT1, SL-Fe-SOD and SLcAPX genes in root, stem and leaf tissues. In addition, expression of SLGR1 and SLGST genes in root tissue was increased. In leaf tissue, expression of SLGPX, SLCu/Zn-SOD and SLGST genes increased significantly. There was no significant change in the expression of the genes studied in the shoot tissue. These results obtained from tomato root, stem and leaf tissues by creating proteasome inhibition will help to understand the relationship between antioxidant system and proteasome system in plants.

title: Microwave assisted drying and extraction technique; kinetic modelling, energy consumption and influence on antioxidant compounds of fenugreek leaves

description: Abstract Fenugreek leaves contains bioactive compounds, which are helpful in maintaining human health. These compounds are adversely affected in conventional drying methods. Therefore, this study was carried out to retain maximum amount of these components through microwave-assisted drying and extraction technique. The technique was optimized for simultaneous drying and extraction process for fenugreek leaves. The drying rate and drying time were influenced by the level of microwave power; time was reduced from 21 to 5 minutes, when microwave power was changed from 30 to 100 W. Unlikely, the drying rate increased from 1.79 to 4.56 ± 0.05 g/(100 g.min) with the change in power (30 to 100 W). Moreover, moisture ratio analysis determined that two term model was the best to demonstrate the fitness with experimental values. The energy consumption was lowest for 100W compared to other powers. Furthermore, comparison between microwave-based extraction and methanol-extraction indicated that the antioxidant activity was better preserved compared to conventional ones even at higher microwave power levels.

title: The combination effect of adding rosemary extract and oregano essential oil on ground chicken meat quality

description: Abstract Preservative effect of oregano essential oil (OE) and rosemary extract (RE) on ground chicken meat stored at different refrigeration time had been evaluated. Six treatments were prepared: T1) Control (No additives); T2) Combination (CM1) of 100 ppm OE and 300 ppm RE; T3) CM2: 100 ppm OE + 350 ppm RE; T4) CM3: 150 ppm OE + 300 ppm RE; T5) CM4: 150 ppm OE + 350 ppm RE; T6) 14 ppm of butylated hydroxyanisole (BHA). Meat patties were individually packaged in oxygen-permeable bags stored at 4 °C, and analyzed for lipid and protein oxidation, and CIE color values at 0, 4, and 7 days. Individual cooked thigh meats were used to evaluate different sensory attributes. All additives showed significant (P &lt; 0.05) antioxidant effect delaying lipid and protein oxidation after day 4 comparing to the control treatment samples. However, the highest significant (P &lt; 0.05) effect among all treatments was by CM4. The CM4 was the highest stabilizing raw meat color, and preventing meat discoloration. In addition, it showed (CM4) highest overall acceptability scores values regarding sensory evaluation. Based on current results, both OE and RE had a potential antioxidant activity; however, this could be stronger if used together.

title: Oxidative stability of the salad dressing enriched by microencapsulated phenolic extracts from cold-pressed grape and pomegranate seed oil by-products evaluated using OXITEST

description: Abstract This study aimed to investigate the potential use of cold-pressed pomegranate seed oil by-product (PGOB) and grape seed oil by-product (GOB) as a natural antioxidant in a salad dressing. Firstly, bioactive compounds from oil by-product were extracted and powdered by spray drier to produced grape seed oil by-product powder (GOBP) and pomegranate seed oil by-product powder (PGOBP). This study was the first attempt to evaluate the oxidative stability of the salad dressing by OXITEST at 90, 100, and 110 °C, and at 6 bar (the oxygen pressure). The samples enriched by GOB (3.22-26.76h) and PGOB (2.49-24.76h) showed high IP compared to control samples (0.43-8.82 h). The oxidation rate was modeled by zero, first and second-order kinetic models, and the oxidation kinetics constant (k) value estimated. PGOBP and GOBP significantly reduced k value. The activation enthalpy (ΔH++), activation entropy (ΔS++) and activation energy (Ea) were 69.78-101.93 kJ/mol, 59.55-81.07 J/mol and (-18.36)-(-83.37) J/mol respectively. The ΔG++ of the control, PGOBP and GOBP enriched samples were 87.36-88.10 Kj/mol, 88.65-91.61 Kj/mol, and 88.14-91.48 kJ/mol respectively. This study suggests that PGOBP and GOBP could be used as a natural antioxidant source for salad dressings.

title: Influence of gum arabic and homogenization process on the physicochemical stability of strawberry suspensions

description: Abstract The generation of value from the strawberry agro-chain requires in some cases the disintegration of the structure and formulation of the fruit, resulting in suspensions that behave as thermodynamically unstable colloidal systems and are affected by various forces, such as Van der Waals, electrostatic, steric, hydration, hydrophobic, and phase separation. The aim of this research was to evaluate the influence of the homogenization process and the concentration of gum arabic (GA) on the stability of strawberry-based suspensions. Strawberries with a 9% solid content were used and a centralized-composite central design was proposed (pressure (P) from 4.14-10.34 MPa), time (t) (3-5 min), and GA (0.2-0.4%)) and the dependent variables zeta potential (ζ), spectral absorption index (R), viscosity (μ), and particle size were evaluated. The ζ potential and R-index were not affected by the homogenization process and GA; the suspension was stabilized by the increase of ζ due to t, the GA effect, and the t-GA interaction. Particle size was affected by P but not by t, whereas GA mainly affected D [3,2], D [4,3], and D90. The results indicate that the homogenization and the use of GA as a hydrocolloid confer chemo-physical stability to the strawberry suspension.

title: Antioxidant dietary fiber-based bakery products: a new alternative for using plant-by-products

description: Abstract Agro-industrial processing activities generate by-products that are discarded at high economic and environmental costs; however, many of them still contain high levels of bioactive compounds (BCs) such as dietary fiber (DF) and phenolic compounds (PCs), which, when combined, are known as antioxidant dietary fiber (ADF). These BCs have properties that are beneficial to our health, among them anti-inflammatory, antioxidant and cardioprotective. Moreover, DF can regulate glucose and cholesterol levels. The mechanism of ADF action depends on its chemical structure and the interactions between the DF and PCs in it. Recent studies have reported the incorporation of several of these by-products on a diet through food products consumed worldwide, such as bread. This review describes the chemical characteristics of the ADF complex and the effect of its molecular interactions on sensory, nutritional and health-promoting properties of functional bakery goods.

title: Dehulling effectiveness of high-oleic and linoleic sunflower oilseeds using air-jet impact dehuller: a comparative study

description: Abstract Sunflower seeds and kernels are very common in the preparation of protein meals. Dehulling sunflower seeds for meal preparation and direct consumption is a very important operation. High-oleic sunflower contains the most oleic fatty acids in the oil which significantly improves the oxidative stability of the meal with this sunflower compared to meals with standard linoleic sunflower seed. In this work, a air-jet impact dehuller was used to determine, optimize and compare the effectiveness of dehulling of two types of sunflower: high-oleic (HOSS) and linoleic sunflower seed (LSS). A two-factorial experimental design (32) was used to estimate the effect of seed moisture and applied air pressure on the efficiency (E criterion) and quality of dehulling (K1 and K2 criteria). Samples with a moisture content of 6, 8 and 10% were dehulled at an air pressure of 400, 600 and 800 kPa. The most efficient dehulling of HOSS, was achieved at a dehulling pressure in the range of 600-800 kPa and moisture content of 6.0%. As for the LSS sample, the highest efficiency of LSS and the highest K2 criterion were obtained at the dehulling pressure of 800 kPa, and moisture content of 7.3%.

title: Type I caramel products of maltose and sucrose with water and their antioxidant activities

description: Abstract To study the caramel reactions of disaccharides with water, the type I maltose caramel products (MCPs) and sucrose caramel products (SCPs) at three reaction stages were yielded and their reaction rates, UV absorptions, flavor compounds, and antioxidant activities were also detected. It was found that the caramel reactions of sucrose were faster than those of maltose and their reaction rates quickly increased to a high level in the middle stage. UV absorption of SCP in the late stage at 305 nm was much stronger than those of MCPs. Both the MCP and SCP obtained at 180 °C and 4 min had the highest concentrations of 5-hydroxymethylfurfural and total flavor compounds. Moreover, the total flavor concentrations of SCPs were much larger than those of MCPs and the antioxidant effects of SCPs were also stronger. Thus, a preferred condition for both two disaccharide caramel reactions was suggested at 180 °C for 4 min and the sucrose caramels could give better flavors than maltose caramels.
