Tıbbi ve aromatik bitkiler (TAB), tüketicilerin doğal beslenme ve yaşama olan ilgisinin artmasıyla birlikte son yirmi yılda ön plana çıkmıştır. Türkiye, bulunduğu coğrafi konum, sahip olduğu iklim ve bitki çeşitliliği sayesinde TAB açısından önemli bir yere sahiptir. Oldukça geniş bir varyete gösteren TAB’ın; lezzet, koku, tat verici, antimikrobiyal, antioksidan ve terapötik gibi etkileri nedeniyle çeşitli formlarda (bütün, öğütülmüş, toz, ekstrakt, ekstre, hidrosol veya uçucu yağlar) kullanımları mevcuttur. Bileşimlerindeki sekonder metabolitlerden dolayı tıp ve eczacılık alanlarının yanı sıra fonksiyonel gıda bileşeni ve takviye edici gıda olarak kullanımları da önem taşımaktadır. Son yıllarda dünya ölçeğinde artarak yaşanan küreselleşme, kentleşme, değişen yaşam koşulları ve beslenme alışkanlarının farklılaşması ile birlikte ortaya çıkan yetersiz ve dengesiz beslenme sonucu tüketicilerin takviye edici gıdalara yönelimini artırmıştır. Takviye edici gıdalar pazarında TAB’ın kullanımına daha fazla yer verilmesiyle bu alanda gerekli düzenlemelere gidilmiştir. Bu derlemede, TAB ile bunların takviye edici gıda üretiminde kullanımı üzerine bazı bilgilere yer verilmiştir.

In completed research, ferrous gluconate -a food additive- used to preserve black color to prevent discoloration during storage in ripe black olives, and Allium cepa L. species. A. cepa L. roots were treated with different doses of ferrous gluconate. The effective concentration EC50 (0.068 g/l) was determined. A. cepa root tips were treated with EC50/2 (0.034 g/l), EC50 (0.068 g/l), 2XEC50 (0.136 g/l) dose for 24, 48, 72 hours, and afterward, the root tips were prepared for observation under the light microscope according to the method of preparing mitotic preparation. Chromosomal abnormality index (CAI) and genotoxic effect of ferrous gluconate in A. cepa root tip cells were determined. Repeated measurement ANOVA and TUKEY multiple comparison tests were used to investigate the effect of time and dose together on genotoxicity. C-mitosis, polyploidy, polar shifting in anaphase, polar shifting in telophase, equatorial plate shifting, laggard chromosome was observed by microscope. The highest CAI (70.16±4.85) was observed at 72h for 2XEC50 dose. Chromosomal aberration is also observed in control group. While the most common chromosomal aberration is determined as C-mitosis; The least observed chromosomal aberration is determined as polyploidy. Research results revealed that ferrous gluconate has a genotoxic effect on the root tip of A. cepa.

To improve hen welfare, several studies have investigated various environmental enrichments that suit different laying hen production systems. The positive results of these studies can enable such environmental enrichments to be utilized in commercial laying hen production. This paper reviewed the effects of environmental enrichments in different laying hen production systems on hen welfare and egg quality. The successfully proven environmental enrichments in free-range production system include forage, shelterbelt, and artificial shade in outdoor area and novel objects and H-shaped perching structures in indoor. These are associated with increased range use that positively affects hen welfare. In aviary system, perches, and litter materials (e.g., straw, sand) as environmental enrichments are linked to improved behavioral expression, reduced stress, and enhanced immune system. Under the litter system, environmental enrichment with substrates (e.g., pecking stones, alfalfa blocks, silage, straw, barley) has been found to increase the foraging behavior of laying hens. This reduces severe feather pecking thus, improving the plumage condition of hens. Although the effects of environmental enrichments on hen welfare have been assessed and scientifically proven in the reviewed studies, significant progress of their impact on egg quality traits has not been reported. The studies have shown that environmental enrichments have no significant effect on egg quality traits. Also, appropriate pasture or plant species as environmental enrichments in free-range production system in relation to hen welfare and egg quality have not been identified. Therefore, it is important to continue studies on environmental enrichments while emphasizing their influence on egg quality since it is a major performance trait in the egg industry. In addition, there is a need for studies to identify ideal pasture or plant species for free-range production system that positively affects hen welfare and egg quality.

There are about 68 types of mulberry fruit with a wide ecological production area. Different mulberry species are grown in large fields in Turkey. Mulberries are largely dried-consumed, but sometimes they are used as fruit juice. In this study, black mulberry fruit was collected in two different ripening levels (semi-ripe and full-ripe) and oven-dried at 50, 60 and 70°C drying temperatures. Initial moisture contents of semi-ripe and full-ripe fruits were determined as 86.74% and 82.95%, respectively. Fruits were dried to have final moisture levels of 10-15%. Drying duration, drying models, effective diffusion, activation energy, specific energy consumption, color parameters and chemical properties of dried fruits were examined and the effect of ripening levels and drying temperatures were investigated. In terms of drying duration, while full-ripe fruits dried in a shorter time, effective diffusion, activation energy and specific energy consumption values were found to be higher than semi-ripe fruits. In terms of color parameters, semi-ripe fruits are recommended to be dried at 50 or 60°C drying temperatures and full-ripe fruits should be dried at 50°C drying temperature for better preservation of color parameters. On the other hand, a common proper drying temperature could not be identified for acidity (pH), water soluble dry matter and titratable acidity.

Mushrooms contain a variety of secondary metabolites, including various phenolic compounds, which have been shown to act as excellent antioxidants. In this study, the contents of total phenolic, flavonoids and tannins of mushrooms methanolic extracts were evaluated by colorimetric assays to ranges of 277.36±0.66 to 420.86±0.90 mg (GAE)/100g DW; 31.99±0.90 to 90.90±0.07mg (QE)/100g DW and 150.61±0.16 to 220.47±1.01mg (TAE)/100g DW respectively. HPLC-profiles of methanolic extracts indicated that the individual phenolic compounds found to the samples of the species of mushrooms that are Lentinus squarrosulus and Auricularia politrich revealed us that gallic acid, catechin, acid ρ-hydroxybenzoїc, acid ellagique and naringerin were presented to the level of the two species. With respect to organic acids, the results showed that citric acid and fumaric acid was the major organic acid in all the samples of both mushrooms species. The methanolic extracts of the two mushrooms exhibited the high DPPH radical scavenging activities ranging from 34.10±1.12 to 58.95±0.52%. These data indicated that these mushrooms could constitute a potential good source of natural antioxidant for the local population.

A research was carried out to assess the suitability of surface water for irrigation purposes. For this reason, 56 samples of surface water were collected from each union of Dinajpur sadar upazilla, Dinajpur. The analysis was included pH, EC, TDS, Ca, Mg, S, P, Na, K, Cl- and HCO3- to evaluate the suitability of surface water for irrigation purposes. Almost all the water samples were within the recommended pH value for irrigation and a great impact on crop production. With respect to electrical conductivity (EC) samples were low to medium salinity. For total dissolved solids (TDS), all samples were considered as freshwater for irrigation. On the basis of Ca, Mg, S, P, Na, K, Cl- and HCO3- all samples could safely be used for irrigation and would not affect the soils.

The aim of this study was to determine the effects of adding orange peel (PKY), lemon peel essential oils (LKY) and PKY+LKY (respectively 300, 300, 150+150 mg/kg) to laying quail diets on performance, egg internal and external quality parameters and hatchability parameters. The eight-week trial was conducted in 20 subgroups, with 4 treatment groups and 5 replications for each treatment, and a total of 120 Japanese quails at 10 weeks of age were randomly distributed, with 6 quails (4 females, 2 males) in each subgroup. Feed intake with the addition of LKY to the diet, egg production and egg mass with the addition of PKY + LKY decreased significantly compared to the control group, and the eggshell breaking resistance with the addition of LKY and PKY + LKY increased significantly compared to the control group. However, the addition of LKY, PKY and PKY+LKY to the diet did not affect hatchability and reproduction parameters. According to these results, the addition of 300 mg/kg PKY and 300 mg/kg (150+150) PKY+LKY to breeder quail diets had an effect on the increase of eggshell qualityi, although the performance was adversely affected.

In this study aimed to determine the effect of ultrasound and microwave assisted extraction on fatty acids yield. Fatty acid components of Tamarindus Indica (T. Indica) seed were determined using ultrasound assisted microwave extraction method. T. Indica is cultivated in the tropics and in Egypt and India. Its fruits are 12-15 cm long, brown and leguminous. In addition to its positive effects on the digestive system, it is an excellent source of vitamin C and a rich antioxidant. It has also been proven beneficial in keeping blood sugar balanced. Fatty acid components were determined by Gas Chromatography-Mass Spectroscopy (GC-MS) method. In addition, the effects of the solvent on the fatty acid yield were investigated. When the results of the analysis were examined, the highest yield was obtained when ethyl alcohol and methyl alcohol were used as solvents. Another important solvent is acetone. The least product was achieved when hexane was used as solvent. Linoleic acid and arachidic acid were detected in each type of solvent used. Capric acid, ligroseric acid and nervotic acid, which are important fatty acids, are detected only in methyl alcohol extraction. The ultrasound assisted microwave extraction method was found to be much faster than the traditional Soxhlet extraction method.

Family health centers in Turkey started to be implemented for the first time in Düzce in 2004 years within the scope of Law No. 5258. While determining the physical conditions of the places where family health centers are built, the first item in the regulation is that the building should be easily accessible. This situation shows the importance of the subject in terms of accessibility. While determining the features of the places where FHCs will be made, environmental characteristics are also taken into consideration. Environmental features are effective in determining the FHCs location in different ways. These impacts are divided into two groups: the physical features that pavements, roads and parks can include, and the social, cultural and institutional features of neighborhoods that include local social ties and collective activities. From this point of view, the importance of the location of family health centers relative to roads and houses is understood. The aim of this study is to examine the accessibility of Family Health Centers in Konyaaltı, Antalya, on a neighborhood basis using Geographic Information Systems. Konyaaltı has 21 Family Health Centers. As a result of the analyses, it was determined that most of the neighborhoods had problems in terms of accessibility, while a very few of them did not experience problems in terms of accessibility. In terms of the total number of buildings, the ratio of buildings that are 500 meters walking distance from any family health center by using highways is 35.56%. With these rates, 3,634 of the 10,2018 buildings remain within the limits of the regulation. Finally; suggestions were made to increase accessibility to these areas.
