A two-year field study (2013−2014) was performed to evaluate phytochemical content and antioxidant activity of two high-lycopene tomato breeding lines (HLT-F71 and HLT-F72) grown under open field conditions as compared to the traditional cultivar (cv) Rio Grande. Two open-field trials were conducted in 2013 and 2014. Three tomato cvs were used: two high-lycopene tomato advanced breeding lines (HLT-F71 and ‘HLT-F72’) (F7 generation), and the open-pollinated cv Rio Grande commonly grown in Tunisia. Regardless the growing years and cvs, lycopene content ranged from 98.8 to 280.0 mg/kg fw, total phenolics from 176.1 to 831.8 mg GAE/kg fw flavonoids from 169.7 to 552.1 mg RE/kg fw and total vitamin C from 183.4 to 370.0 mg/kg fw. Significant year-to-year variability was only detected in total phenolics and flavonoid content. No significant year-to-year variability in antioxidant activity was detected in high-lycopene lines. Disregarding the cv, tomato berries harvested on July 2014 had 143% - 224% higher total phenolics and 8% to 47% higher flavonoid contents compared to tomato berries harvested on July 2013. However, disregarding the cv, tomato berries harvested on July 2013 had 6% -17% higher lycopene and 8% -21% higher LAA compared to berries harvested on 2014. During the second growing year, the higher temperature, particularly prior to harvest, determined a decrease in lycopene content and a significant increase in total phenolics regardless the cv. Although the huge variability in total phenolics and the decrease in lycopene content during the second harvest, the antioxidant activity was not affected by year-to-year variability. This reveals consistent functional quality of these cvs and minimal genotype*environmental conditions interaction.

The objectives of this study were to determine the saline concentration and moromi’s fermentation duration of Koro Benguk salty soy sauce at best organolepticly and determine consumers’ preferences towards Koro Benguk salty soy sauce from the best treatment results. The study was conducted using a randomized design method using two factors: the saline concentration (17%; 20%; and 23%) and duration of moromi’s fermentation (2; 3; and 4 weeks).

The obtained protein was 7.14%; and dissolved solids of 27obrix. Consumers’ preferences towards the best treatment showed that product of Koro Benguk salty soy sauce was acceptable to consumers.

The aim of the study is to evaluate all the factors determining the milk production and yield decisions with regard to the nutrition and feeding programs affecting the integrated management strategies on the success of the dairy farms with culture breed cattle under the pasture-based and indoor barn-based production systems. For these aims, data obtained from the individual interviews conducted at the dairy farms with 100 culture breed cattle were used for Principal Component and Multiple Regression Analyses. The results of the study highlighted that while there were linear positive relationships among liquid assets of farms value, concentrate feed and fodder intake of dairy cattle, milk sale price, forage crop support, additional feeding and their types at pasture and milk yields per dairy cattle at the dairy farms; there were inverse relationships among hay intake of dairy cattle, lactation period, pasture planning, culture breed cattle support and those. The farmers could increase the successes of the dairy farms by increasing the technical and economic effectiveness under the integrated management pattern approaches at those with culture breed cattle.

This study was carried out in order to analyze seafood consumption level of consumers in Central Anatolia Region (Province Ankara) and their consumption behavior. Proportional sampling method was used in determining sample size and sample size was determined as 167. Data were collected from randomly chosen individuals with face-to-face interviews. As a result of study, in order to determine possible effects of socio-economic properties of consumers on seafood consumption, CHAID analysis which is one of the decision tree analyses was used. According to the results of analysis; it can be said that dependent variables of income, education and age have effect on attitude and behavior of consumers while gender have no effect on consumption behaviors.

Post-harvested blackberry, raspberry and strawberry fruits were immediately treated with 1% and 2% calcium chloride by immersion at 20 ± 1°C for 2.5 min and kept for 8 days at 0 ± 0.5°C and relative humidity (RH) 90 ± 5%. The application of calcium did not significantly effect on total titratable acidity, pH and total soluble solids. Maximum weight lost was observed for untreated berries and minimum lost was observed for fruits treated with 2% calcium chloride. After storage, ascorbic acid content was significantly higher in samples of blackberry, raspberry and strawberry fruits subjected to 2% calcium chloride dip. Treatment of blackberry, raspberry and strawberry fruits with calcium chloride had a positive effect on retention of total polyphenols content during the storage period. Depletion of antioxidant capacity of untreated fresh blackberry fruits during 8 days cold storage was 25%; raspberries and strawberries - 34 and 26 % respectively. Whereas depletion of antioxidant activity in the 2% calcium chloride treated samples of these fruits was 8, 22 and 11% respectively. In case of storage of untreated blackberry fruits content of cyanidin-3-O-monoglucoside decreased by 6.33 mg per 100 g of fruit. While, in fruit samples treated with 1 and 2% calcium chloride content of cyanidin-3-O-monoglucoside decreased by 32.06 and 11.35 mg per 100 g of fruit, respectively. Content of pelargonidin 3–O- monoglucoside increased by 2.29 mg per 100 g of the untreated blackberry fruits and by 26.87 and 8.45 mg per 100 g of fruits treated with 1 and 2% calcium chloride respectively. Change of content of cyanidin 3–O- (6 - p – coumaroyl - glucoside) in blackberry fruits was not statistically significant.

This study was conducted to assess the effect of drying methods and pre-treatments on nutritional content and sensory quality of dried fish. The experiment was conducted in factorial arrangement of 2×3×2 with two drying methods (sun and oven drying), three fish species (tilapia, cat fish and carp) and two preservatives treatment (garlic and ginger juice) laid out in Completely Randomized Design (CRD). Fresh fillets were analysed for their nutritional value and sensory quality. The compositions of the fresh fillets were 6.50-7.59% for ash, 74.20-76.67% for protein, 8.06-9.09% for fat and 8.47-9.12% for total carbohydrates. Drying reduced the moisture contents from 74.74-75.81% to between 7.76-8.25%, making it safe for storage. The ash content changed from 7.11 to 7.34 and from 6.50% to 6.34% for cat fish and tilapia, respectively, with statistical significance whereas no change was observed in carp with 7.60% because of drying. Drying method had no difference in ash and protein contents while increase in fat from 7.75 to 9.44% and a decrease in carbohydrate from 9.37 to 8.13% were observed in sun dried samples than that of oven dried fillets. This study showed that nutritional values of dry fish did not statistically changed during storage period of 3 months.

Human being have been consumed mushrooms due to their aroma and flavour. The macro-nutritional properties such as ash, protein fat, carbohydrate and energy and fatty acid ingredients of Lactarius deliciosus (L.) Gray, Lactarius deterrimus Gröger, Lactarius salmonicolor R. Heim & Leclair and Lactarius semisanguifluus R. Heim & Leclair were studied. The results indicate that the moisture was between in the range of 86.8-91.1%, while the ash 5.1-9.2%, and the protein 9.4-19.0%, and the fat 0.6-1.1%, and the carbohydrate 71.8-83.9, and the energy calculated between 372.1-382.6 kcal/100 g dry weights. The major fatty acids were determines as stearic acid, oleic acid, linoleic acid and palmitic acid in the range of 6.68-39.41%, 26.94-47.12%, 9.78-23.85% and 9.7-14.43% respectively.

Modified atmosphere packaging (MAP) technology is gaining popularity worldwide for its potential of extending shelf life of fresh produce with better fruit quality. Effect of MAP (using Xtend® bags), was investigated on postharvest storage life and quality of mango cvs Sindhri and Sufaid Chaunsa stored at 11°C with 80-85% RH for 4 and 5 weeks respectively, in comparison with un-bagged (control) fruit. Uniform physiological mature fruit of Sindhri and Sufaid Chaunsa were harvested from a commercial mango orchard along with 4-5 cm long pedicel and were de-sapped in 0.5% lime solution (to avoid sap burn injury). Later on fruit were given cold water fungicidal dip (Sportak @ 0.5ml/L, Active Ingredient: Prochloraz) followed by hot water treatment (52°C; 5 min). After shade drying and pre-cooling (11°C; 10-12 hours), fruit were packed according to the treatment combination and stored at 11°C. Fruit of both varieties were removed after 2, 3 and 4 weeks of storage followed by ripening at 24±2°C with an additional removal after 5 weeks for Sufaid Chaunsa only. Fruit quality was evaluated for various bio-chemical, organoleptic and physical parameters at two stages of ripening (at removal day and at final ripening day). Fruit of both varieties stored in MAP exhibited better firmness and retained green colour as compared to un-bagged fruit. Quality of fruit subjected to postharvest fungicidal application and hot water treatments and stored under MAP at 11°C showed better peel colour development and less disease development. Moreover, storage durations and post storage ripening stages significantly affected fruit peel colour, textural softness and disease development. Further, cv. Sindhri showed better storage potential with lower disease incidence as compared to cv. Sufaid Chaunsa which warrants further studies on disease control aspects.

This study examined kinetic modeling of the detoxification induced by dechlorination of laccase enzyme obtained from Trametes versicolor which is a white rot fungi strain and 2,4,6-trichlorophenol which is a toxic chlorinated phenolic compound. In the evaluation of the kinetics of detoxification induced by dechlorination of 2,4,6-trichlorophenol used as substrate, the Systat 10 software package which is a statistics program was used while two-substrate solution environment was used to explain the kinetic behavior of the dechlorination. It was observed as a result of experiments and statistical analysis that Moser equation is the optimal kinetic model. Given the statistical data obtained and the graph, the dual-substrate model was found to be compatible with the experimental data. The bio-kinetic parameter values obtained for the model that identifies enzymatic dechlorination kinetics were calculated as Vmax =9.341 ppmO2/min, Ks =38.254 g/L, Ko =20.747 ppm, R = 1.895 and N = 1.233. In the literature, no studies were found on kinetic modeling for the degradation of 2,4,6-trichlorophenol, and through this study, we have been first to conduct a study on kinetic modeling of the degradation induced by enzymatic dechlorination of 2,4,6-trichlorophenol. The GC/MS analysis results showed that the chlorophenolic compound used throughout the enzymatic dechlorination performed with laccase enzyme was degraded 80% to 100%. Based on the GC/MS analysis results, the conclusion that the enzyme responsible for the dechlorination was laccase was also found to support the findings available in literature.
