Nida Nur Urgancı | Nazife Yılmaz | Gamze Koçer Alaşalvar | Zeliha Yıldırım
Pseudomonas aeruginosa, belonging to the Pseudomonadaceae family, is Gram-negative, rod-shaped, motile, aerobic, endospore negative, oxidase and catalase positive. It is widely found in nature and isolated from soil, plants, water and animals. It can grow rapidly on the surface of the food and form oxidized products and mucous substances. P. aeruginosa, one of the leading foodborne pathogens, causes important concerns in food safety due to being a source of contamination, causing food poisoning and antimicrobial resistance in animals, forming biofilms and difficulties in preventing biofilms. In this review, information on history, microbiological, cultural and biochemical characteristics, virulence factors and pathogenicity of P. aeruginosa are given. In addition, infections caused by P. aeruginosa and its presence in food are described.

The fall armyworm [Spodoptera frugiperda, (JE Smith, 1797) (Lepidoptera: Noctuidae)] is a polyphagous pest native to tropical and subtropical regions of America. After it was detected for the first time in Nepal in the Nawalpur area on 9th May 2019, it has become a major threat in maize fields even though it has over 80 host species to proceed its life cycle. Due to its migratory nature, FAW moth can travel up to 500 km before oviposition, and infestation of its larva has resulted in vast devastation of the vegetative as well as reproductive parts of plants causing significant yield loss in maize. A mature larva possesses a dark head with an upside-down pale Y-shaped marking on the head area and black four spots that are arranged in a square on the second last body segment. This paper audits the executive choices (avoidance, observing, push-pull, cultural, biological, organic, chemical, and integrated techniques to incorporate in FAW susceptible areas) that apply to smallholder farmers who do not have the monetary asset to buy compound pesticides and other costly control instruments. For the majority of Nepalese farmers with low resources and small landholding, push-pull technology is beneficial and applicable. Botanicals that have bioactive chemical compounds, insecticidal, pest repellent properties are environment-friendly and degradable, readily available in tropical and subtropical regions of Nepal. The assessment of the efficacy of implemented management practices against FAW has revealed that implementation of more than one method of management practices showed the least percentage of infestation as compared to the individual method.

The current research was carried out to determine the effect of adding sodium formate at the level of 0, 5, and 10 g/kg to the diets on the performance, egg quality and some serum parameters in layer Japanese quails. In the experiment, a total of 84 female quails at the age of 20 weeks were randomly distributed to 3 treatment groups with 7 replicates. At the end of the experiment, the addition of sodium formate at different levels to the diet did not statistically affect performance and egg quality parameters. Compared with the control group, the supplementation of 10 g/kg sodium formate to the diet considerably decreased the serum glucose concentration, while the serum calcium concentration increased significantly. Furthermore, the administration of sodium formate to diet significantly decreased serum triglyceride and cholesterol concentrations. According to the results obtained from the study, it was determined that the addition of sodium formate to the diet was effective in reducing serum glucose, triglyceride and cholesterol concentrations and increasing serum calcium concentration without affecting the performance and egg quality parameters of laying quails, and this effect was more pronounced at 10 g/kg sodium formate level.

The aim of this study was to reveal the effect of whey powder (WP) supplementation on chemical composition, silage fermentation, in vivo digestibility and net energy lactation (NEL) value of high dry matter (DM) alfalfa silage (Haylage). Alfalfa treated with different doses WP (0, 2, and 4%) were ensiled in plastic cans for 60 days. Nine Kıvırcık rams were used to estimated digestibilities of haylages in 3x3 Latin Square design with fifteen days experimental period. According to the results, the addition of WP significantly increased the DM of alfalfa haylage compared to the control whereas decreased ether extract, crude protein and crude ash. But, cell wall fraction rates of all groups were similar. Relative feed value and physical characteristics other than color improved in WP supplemented groups, and lactic acid rates increased in these groups. In terms of silo acids, the best values were found in the group with 4% WP. On the other hand, the addition of WP increased the organic matter digestibility of haylages, however the effect on other in vivo digestibility of crude protein, crude fiber, nitrogen free extract and neutral detergent fiber was insignificant. Moreover, total digestible nutrients (TDN) and NEL values of haylages were found to be improved with the addition of WP. As a result, it was concluded that in order to obtain quality haylage in the ensiling of high DM and long chopped alfalfa, WP generally can be used as an alternative source of carbohydrates and a 4% whey powder dose can be recommended in the production of haylage especially in the sense of improving silage fermentation.

Poor germination and suboptimal seedling growth constitute as prime factors in lowering the achene yield and seed oil content of sunflower (Helianthus annuus L.), while chemo-priming with micronutrients might serve as a biological viable strategy provided source and dose optimization are performed. A trial was executed to appraise the comparative impact of seed priming with different doses of micronutrients like boron (B) and zinc (Zn) on sunflower germination and seedling growth traits of sunflower. The experiment was comprised of six treatments of B (0, 0.2, 0.4, 0.8, 1.6, 3.20 ppm) and Zn (0, 4, 8, 12, 16 and 20 mM) each, while seed germination, root and seedling growth related traits were taken as experimental variables. The results revealed that all treatments remained ineffective regarding seed germination and seed vigour of sunflower, while B and Zn doses of 0.2 ppm and 12 mM respectively, enhanced seedling emergence rate and vigour. The Zn (8 mM) significantly improved root length along with their fresh and dry weights, while all doses of B imparted antagonistic effects on root attributes. Likewise, Zn (8 mM) remained superior for shoot length, fresh and dry weights, while higher doses of B remained contra-productive for shoot growth of sunflower.

Mechanical properties provide information to design and develop suitable machines (equipment) for processing, transporting, and conveying chestnuts. Four chestnut cultivars that have not been studied before were investigated in the study carried out for this purpose. Some engineering properties of Macit 55, Akyüz, Ali Nihat, and Bouche de Betizac chestnut cultivars were determined and compared. The mechanical properties were determined by rupture force, rupture energy, deformation, and firmness values. The friction coefficients of chestnut varieties on a galvanized sheet, stainless steel, and rubber surfaces were investigated. Mechanical properties were determined using a Universal Testing Machine. The values obtained from the samples were obtained by compression between the parallel plate along the X, Y, and Z axes. For the static friction coefficient, while the galvanized sheet surface had the lowest value (0.145), the rubber surface had the highest value (0.212). For rupture forces, the force required to break the chestnut at the Z loading axis position (714.09 N) was higher than the required force at the Y loading axis position (396.35 N) of the fruit.

Tea is a popular beverage with potential health benefits for those who consume it regularly. Tea products with health claims require scientific evidence based on clinical trials with generally accepted scientific data and newly developed scientific data. Tea products have been labelled FOSHU in Japan, claiming to reduce body fat and cardiovascular risk. In The USA, health claims on tea cannot be recommended and categorized as Qualified Health Claims. In Europe, health claims for tea still required further research to provide accepted scientific data. This review aims to explain the position of tea products based on the perspective of the regulatory framework of food health claims in the different official agencies in the United States, Europe, and Japan.
Mostrar más [+] Menos [-]Evaluation of The Effects of The Use of Vegetable and Fruit Extracts on Bread Quality Properties Texto completo
2022
Meryem Akbaş | Hilal Kılmaoğlu
Bread is the basic nutrient that human beings have consumed for centuries. This is because it is affordable, nutritious and satisfying. The most consumed bread on a daily basis is white bread made from refined flours. Since white breads are made from flour that has been separated from the bran and germ, they are poor in other nutrients (dietary fiber, phenolic compounds and minor nutrients) with a high starch content. For this reason, studies on increasing the nutritional value and functionalization of white bread have attracted attention for years. In this study, the changes in physical, chemical, sensory and textural properties of bread were evaluated with the addition of purple cabbage, sorrel, capia pepper, pomegranate, pumpkin and cherry extracts to bread production. It was determined that the bread was enriched with phenolics with the addition of extracts (65% on flour basis) and the best sensory results were the breads with the addition of capia pepper extract.

Duried Alwazeer | Tunahan Engin
Molecular hydrogen is a colorless, odorless, tasteless, non-toxic, flammable, and diatomic gas. Molecular hydrogen is dissolved directly in water to be used in the form of hydrogen-rich water (HRW) to keep the freshness of fruits and vegetables. The shelf-life of the product was increased and the quality attributes were maintained when hydrogen was applied to some food products such as milk, tea, and fruit juices. Some grain products and greens grew rapidly and their antioxidant substance levels increased when they were supplied with hydrogen-rich water. Molecular hydrogen has shown an important application in food drying in recent years, was used especially in reducing atmosphere drying (RAD) technology. Few studies have been conducted on the use of molecular hydrogen in food products. Due to its various positive effects, the use of molecular hydrogen in the food industries using different techniques and processes could be encouraged by the presence review
