Gökhan Akarca | Elif Başpınar
Pomegranate (Punica granatum L.), based on the origin of Southeast Asia and Turkey, with a large growth area such as the Mediterranean and the Arab countries, is the most important plant belonging to family Lythraceae. Pomegranate peel and seed contain numerous and various bioflavonoid, which is indicated to be both antimicrobial and inhibitors of enzymes such as cyclooxygenase and lipoxygenase. The antioxidant, antimicrobial, and antifungal properties of the pomegranate are related to phytochemicals such as delphinidin, cyanidin, pelargonidin, ellagic acid, punicalin, punicalagin, pedunculagin, and different glucosides, which involve anthocyanins. In this study, it was investigated that ethanol, methanol and distilled water extracts, obtained from Punica granatum L. antimicrobial effect against Bacillus cereus, Listeria monocytogenes, Escherichia coli, Enterobacter aerogenes, Salmonella Typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa bacteria known as food pathogen by using disk diffusion method. Also, minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values on seven different food borne pathogens were also determined. As a result of the research; pomegranate seed extracts obtained from methanol observed the highest antimicrobial effect against Pseudomonas aeruginosa with a 29.02 mm zone diameter, while pomegranate peel extracts obtained from ethanol observed the highest antimicrobial effect against Bacillus cereus with a 26.84 mm zone diameter. The MIC and MBC value against Pseudomonas aeruginosa are determined 7.81 µg/L, while The MIC and MBC value against Bacillus cereus are determined 31.25 and 15.63 µg/L, respectively.

The aim of the study was to design the drinking milk profiles according to the factors and their levels effecting on the consumers’ purchase decisions towards drinking milk with the region of origin at the retailer level, and then to determine the market shares (MS) and the consumers’ willingness to pay (WTP). Research data were obtained from 160 households consuming drinking milk in Iğdır province. Conjoint Analysis were used to design drinking milk profiles with the region of origin, and to determine their market shares (MS) and consumers’ willingness to pay (WTP). The result of the study highlighted that the marketing shares of the first three drinking milk profiles maximizing the consumers’ total utilities were calculated as %34, %12 and %10 (card number 7, 6 and 1), respectively. On the other hand, the consumers’ willingness to pay under the origins and price levels of drinking milk were analyzed as %26 for Aegean/Marmara Region, %16 for Northeast Anatolia Region and %12 for Eastern Black Sea Region at the lowest price levels. By having designed drinking milk profiles maximizing the consumers’ total utilities, the marketing share and penetration rates of the products could increase, and the product profiles responded to the consumers’ willingness to pay could also satisfy considerably on their purchase decisions.

Vegetables supply various minerals, vitamins, dietary fibers along with important phytochemicals that plays a major contribution in our balance diets and nutrition. Each vegetable contain a unique amount of various nutrients that are strongly linked with the protection of different health diseases. Eggplant (Solanum melongena L.) is a nonwoody annual plant with purple to white flowers along with enlarged lobed leaves with bushy foliage that grows with maximum height of 120cm. Eggplant is mainly grown for vegetables and medicinal purposes. The phytochemical analysis of eggplant shows that it is the rich source of various essential compounds aspartic acid, tropane, flavonoids, lanosterol, gramisterol, steroid alkaloids, glycoalkaloids, histidine, nasunin, oxalic acid, solasodine, ascorbic acid and tryptophan that are present in fruits and leaves. It also contains low calories and high moisture contents. These compounds were found helpful in the cure of various diseases like cancer, anti-inflammatory, anti-asthmatic, anti-platelet hypo-lipidemic, and hypotensive etc. Today most modern scientific techniques are available to cure different various health problems but still majority of population across the globe depends upon the traditional herbal medicines and practices.

In this study, the antioxidant activities and biochemical characteristics of Ulva rigida (Ulvophyceae) and Arthrospira platensis (Cyanophyceae) were determined. The extracts from two seaweed species were evaluated for their free radical scavenging activity, using the 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) method, their total phenolic, flavonoid, and condensed tannin contents, through Folin–Ciocalteu, Quettier-Deleu, and Price methods, respectively. The extracts of two seaweeds showed a low free radical scavenging capacity in comparison with commercial antioxidant BHT (butylated hydroxytoluene), and vitamin C. The extract of U. rigida demonstrated greater antioxidant potential with a low IC50 (3.76±0.02 mg/g Ext.). The total phenolic contents were ranged from 2.21±0.08 (U. rigida) to 8.59±0.62 (A. platensis) mg GAE/g of extract. The highest flavonoid content was found in A. platensis as 22.70±0.65 mg rutin/g of extract. The contents of condensed tannin were measured 3.01±0.11 mg CE/g of extract for A. platensis and 3.76±0.06 mg CE/g of extract for U. rigida. According to results obtained, U. rigida and A. maxima possess antioxidant activity and could be used in for future applications in medicine, functional foods, and agriculture.

This study was undertaken to assess the combining ability of 6 rice varieties, for viscosity parameters and determining gene action controlling Rapid Visco Analyser (RVA) characters. F2 progenies derived from a 6×6 half diallel mating design with their parents were grown in a randomized complete block design with three replications at the research farm of Rice Research Institute of Iran (RRII) in 2015. The diallel analysis by Griffing`s method indicated the involvement of additive and non-additive gene actions controlling RVA traits. For traits PV and FV RI18447-2 and IR50 were the best combiners for increasing and decreasing, respectively. Deylamani and IR50 were the best combiners for increasing and decreasing BV, respectively. Beside, due to more portion of non-additive gene action in controlling trait SV, The Gilaneh × RI18430-46, and Deylamani × RI18430-46 crosses were the best for increasing and decreasing SV, respectively. The high estimates of broad sense heritability and narrow sense heritability for BV and FV, indicated the importance of additive effects in expression of these traits. Therefore, selection base breeding methods will be useful to improve these traits and selection in the early generations could be done to fix the favourable genes. Low estimate of narrow sense heritability for SV revealed that non-additive gene effects play important role in controlling setback viscosity. So, hybrid base breeding methods will be useful to improve this trait.

It is known that agricultural lands remain limited due to the ever increasing human population. That is why the necessity of increasing the crop production is constantly emphasized. In the crop production, quality should be increased along with yield. Nonetheless, there are amounts that people should take from each group of nutrients daily to ensure adequate and balanced nutrition. As known, malnutrition has negative effects on human health, which causes some diseases. Field crops, as well as other feeding groups, are of great importance in human nutrition. It is known that oil plants, which belong to the group of industrial plants, have an important place in human nutrition as in the vast majority of field crops. Thus, in this article, some important oil plants will be examined in terms of human nutrition.

Plant secondary metabolites are a group of organic compounds produced by plants to interact with biotic and abiotic factors and for the establishment of defence mechanism. Secondary metabolites are classified based on their biosynthetic origin and chemical structure. They have been used as pharmaceutical, agrochemical, flavours, fragrances, colours and food additives. Secondary metabolites are traditionally produced from the native grown or field grown plants. However, this conventional approach has some disadvantages such as low yield, instability of secondary metabolite contents of the plants due to geographical, seasonal and environmental variations, need for land and heavy labour to grow plants. Therefore, plant cell and organ cultures have emerged as an alternative to plant growing under field conditions for secondary metabolite production. In this literature review, present state of secondary metabolite production through plant cell and organ cultures, its problems as well as solutions of the problems were discussed.
