2023
Iustus Alwis | Sachini Ariyachandra | Ruvini Kamalika Mutucumarana | Ruwini Basnayake
The study described herein aimed to investigate the relationship between perceptions of hormone usage and customer preferences for broiler meat and meat products in Sri Lanka with special reference to Kandy district. A total of 460 respondents from Kandy district were interviewed using a pre-tested questionnaire. The analysis revealed that 85.9% of the respondents believes the fact that the hormones are used in broiler production. Also, 75.7% of the respondents were unaware about the fact that the hormones are totally banned from Sri Lankan broiler production. Around 71.4% believed that the hormones are still being used illegally in broiler production in Sri Lanka. The study also found that the general public (36.2%), was the main source that the respondents perceived this false information concerning hormone use. Similarly, 83.7% believes that these chemical substances create health hazards to human. 76.7% of the respondents strongly believed the fact that the adolescent girls who consume broiler meat regularly during their childhood may experience early puberty. The findings of the present study concluded that three misconceptions of (i) use of hormones to attain high growth rates in broilers (ii) hormones assumed to be present in broiler meat pose health hazards to public and (iii) frequent broiler meat consumption during childhood is accompanying with the early puberty in adolescent girls, do exists. Though the majority of the sample comprises of highly educated professionals, these misinformation were spreaded from the information generated among the general public. However stipulating a valid certification with no added hormone in broiler chicken meat will be helpful in changing the mind-set of general public.

Ayşegül Gür | Kubilay Kurtuluş Baştaş
Necrogenic Gram-negative bacterium Erwinia amylovora, which causes economic losses especially in pome fruits such as apple, pear, quince and loquat, some berries and many ornamental plants, causes fire blight disease. Copper compounds are used extensively in disease control programs and they can cause toxicproblems in terms of plant and environmental health. In addition, the formation of resistance to copper in the pathogen is frequently observed. In this study, plant activator phosphorous acid and biological control agent Bacillus subtilis, and 3 different copper compounds, Copper sulfate, Copper oxychloride and Copper hydroxide which are commonly used against E. amylovora, on apple cv. Gala with M9 rootstock were evaluated comparatively. When the new season shoot lengths of 3-year-old plants with homogeneous growth reached 20-25 cm, chemicals and B. subtilis were applied first time before one week ago from the pathogen inoculation, and after 2 times with 1 week intervals. The youngest two leaves at tips of actively growing terminal plant shoots were inoculated by cutting off using scissors dipped in suspension of E. amylovora str. EaARADY5 containing 108 CFU ml-1. Disease assessments were made after the disease severity (%) was determined on the basis of shoot blight after symptom development of the disease stopped, and the results were found to be statistically significant (p<0.05). According to the findings, while the highest effect was obtained by copper oxychloride with 69% effectiveness among all applications, the lowest effectiveness was obtained with 43.5% copper sulfate. It has been revealed that the use of the most effective of the copper compounds in field applications will result in less exposure to chemicals in terms of human and environmental health, and that B. subtilis and phosphorous acid can be used significantly in the integrated control of fire blight.

Erzincan Tulum Cheese (ETC) holds a significant place among the most popular cheeses in Türkiye. It has been awarded Protected Geographical Indication status, which restricts the allowable milk species, its production area, and specific sheep breed used in its production. Mineral content and antioxidant activity of ETC were aimed to be predicted using conventional FT-NIR and a portable FT-MIR spectrometer combined with partial least square regression (PLSR) and machine learning algorithms based on conditional entropy. Seventy ETC samples were analyzed for their mineral (Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, and P) content using ICP-MS. The samples' antioxidant activity was measured using the DPPH•+ scavenging activity method. PLSR combined with FT-NIR spectral data correlated with antioxidant activity (r=0.89) and minerals (as low as r=0.83) except for Cr and Fe. FT-MIR data provided a good correlation for minerals (as low as r=0.82) except for Cr and Mn and a moderate correlation with antioxidant activity (r=0.64). Information theory was applied to select wavenumbers used in machine learning algorithms, and better results were obtained compared to PLSR. Overall, FT-NIR and FT-MIR spectroscopy provided rapid (~ 1 min), non-destructive, sensitive, and reliable output for mineral and antioxidant activity predictions in commercial cheese samples.

The belief that ancient wheat is more beneficial than common wheat has been growing trend in recent years among the consumers. The present study aims to compare bioactive peptide, allergen peptide and toxic peptide generation after gastrointestinal digestion of modern wheat (Triticum aestivum) and ancient wheat, einkorn (Triticum monococcum var. monococcum), using in silico tools. The primary sequences of both kinds of wheat were obtained from BIOPEP-UWM and UniProtKB/Swiss-Prot database. In silico digestion was applied using BIOPEP-UWM online tool. For the simulation of gastrointestinal digestion pepsin (pH 1.3) (EC 3.4.23.1), trypsin (EC 3.4.21.4), and chymotrypsin (EC 3.4.21.1) were selected and analyzed. Homology analysis was performed for each protein sequences using EMBOSS Needle program. Toxic and allergen peptides were predicted using ToxinPred online tool and Allergen FP v.1.0. The results showed that einkorn and common wheat proteins exhibited similar properties including high similarity rate (58.72-87.40%) indicating the percentage of matches between the two sequences and the identical bioactivities for peptides generated after digestion. Most of the bioactive peptides were dipeptides and the majority of them displayed more than one bioactivities including ACE inhibitory, DPP IV inhibitory or antioxidant activity, etc. Allergen peptides generated after in silico digestion were found to be similar for both kinds of wheat. In silico gastric digestion of einkorn and wheat caused toxic peptides production, but they were disappeared after in silico intestinal digestion. In conclusion, although there is a perception related to the Einkorn that is healthier than common wheat, in silico digestion of common wheat and einkorn did not support this perception.

In recent years, there has been a growing interest in herbal remedies for therapeutic purposes. Aromatic plants have become a significant source of raw materials for the fragrance, food, and cosmetics industries. Additionally, the emergence of new applications and the trend towards natural nutrition and alternative healing methods, often referred to as "going natural," have increased the interest in medicinal and aromatic plants in our country, as well as in other countries around the world. In this study were investigated to determine yield and quality characteristics of seven different lavender (Lavandula intermedia Emeric ex Loisel. = L. hybrida L.) (Grasso, Süper-A, Seguret, Dutch, Abrial, Akmeşe, English) cultivars under dry and irrigated cultivation in Kahramanmaraş conditions between 2019 and 2020. The research was carried out in a randomized block design with 4 replications. Fresh stem flower yield was the highest variety Grasso(672.81kg/da). The lowest fresh stem flower yield was found in Seguret variety with 611.33kg/da The highest dry stemless flower yield was determined in Grasso variety with 59,66 kg/da. There were significant differences determined between cultivars the end of 2 years. The highest average fresh stem flower yield (693.067 kg/da) and the highest average dry branched flower yield (252.588 kg/ha) were measured in GRASSO variety.

Conducted within the National Sheep and Goat Breeding “subproject: Akkaraman Sheep Breeding Project under farmer conditions in Nigde’s Bor district” between 2018 and 2022, the current study evaluated the reproductive characteristics of ewes as well as the livability and growth traits of lambs. This study investigated some ‘reproductive traits’ of an average of 6000 ewes per year and ‘growth performance and ‘survival traits’ of a total of 30051 head lambs. The birth weight (LBW), 60th-day body weight (BW60), 120th-day body weight (BW120), and 120th-day body weight gain (BWG120) of Akkaraman lambs during the study periods were 4.14±0.19 kg, 18.58±0.03 kg, 31.31±0.02 kg, and 246±2.23 g/lamb/day, respectively. In the study, among the factors affecting the growth characteristics of Akkaraman lambs, only the effect of gender on BWG120 and birth type on BW120 was found to be insignificant. In contrast, the other factors were found to be found to be statistically significant. In the study, it was determined that the number of lambs per Akkaraman ewe giving birth between 2018-2022 varied between 1.03-1.10. The highest livability in Akkaraman lambs was determined in 2018 (96.61%) and the lowest in 2020 (83.21%). As a result, it was found that liveability in Akkaraman lambs was dependent on birth year, the age of the ewe, gender, and birth type.

2023
Atakan Koç | Mehmet Öner
The aim of this study was to determine the fertility, herd life and milk yield characteristics of Simmental (SIM) cows of Austrian origin, which have increased the interest of cattle breeders in Türkiye in recent years. From the records of the farm between 2011 and 2021, the first calving age (FCA), calving interval (CI), herd life (HL), productive life (PL), lactation length (LL), lactation milk yield (LMY) and 305 days milk yield (305-dMY) were calculated. A total of 307 FCA, 619 CI, 212 HL and PL, 447 LL, 271 LMY and 497 305-dMY data were used. The means of FCA, CI, HL, PL, LL, LMY and 305-dMY for SIM cows were 842.35±5.30 days (28.1 months), 422.98±3.18 days, 75.48±1.72 months, 47.15±1.73 months, 363.52±3.52 days, 10,596±152 kg and 8647.0±58.0 kg, respectively. Based on the long FCA and CI averages of Austrian-origin SIM cattle, although it can be interpreted that there are some problems in terms of reproductive efficiency in the farm, finding long HL and PL and high milk yield, it can be said that the farm contributes to the increase of milk yield per cow by turning the negativity caused by the reproductive efficiency into an advantage.

2023
Nazlı Şahin
The oleaster (Elaeagnus angustifolia L.), also known as wild olive, is a small fruit with three parts: the outer peel or exocarp layer, the edible part or mesocarp layer, and the inner seed or endocarp layer. The mesocarp layer is rich in essential vitamins and has great potential for use in various food products. The flour made from the mesocarp layer has a moisture content of 8.99%, an ash content of 2.66%, a fat content of 0.55%, a protein content of 5.99%, a crude fiber content of 3.32%, and a total dietary fiber (TDF) content of 26.36%. The TDF content is divided into insoluble dietary fiber (IDF) and soluble dietary fiber (SDF), which are 21.35% and 5.01%, respectively. The flour has color values of L*: 75.14, a*: 2.86, b*: 23.87, and a water activity value of 0.314. The water solubility, water absorption, and oil absorption are 67.33%, 4.91 g water/g sample, and 2.26 g oil/g sample, respectively. Additionally, the mesocarp layer contains minerals such as Mg, P, K, Ca, Fe, and Na. The mesocarp layer significantly affected the thermomechanical properties of wheat flour. As the substitution level of the mesocarp layer increased from 10 to 30%, the water absorption capacity, dough development time and stability time of the wheat dough significantly decreased. Specifically, the water absorption capacity dropped from 53.5% to 47%, dough development time reduced from 1.10 to 0.75 min, and stability time decreased from 8.90 to 2.25 min. Substituting a mesocarp layer in wheat flour can significantly improve product shelf-life due to slower retrogradation. The mesocarp layer is an functional ingredient in the food industry.

2023
Ahmet Taskiran | Tuğba Yıldız Asdemir
Recent studies have shown the positive effects of Cucurbita pepo L. (pumpkin) seed oil (PSO) in different disease models. However, the effect of PSO on neurological diseases has not been clarified yet. Therefore, this study aims to elucidate the effects of BBS on pentylenetetrazole (PTZ)-induced neuronal damage and the possible roles of oxidative and nitrosative stress in this effect in vitro. The HT-22 hippocampal neuronal cell line was used in the study. Cell survival after PTZ-induced neuronal damage was evaluated with the XTT test in the groups. While the effects of BBS on total antioxidant status (TAS) and total oxidant status (TOS) after PTZ were measured with colorimetric commercial kits, its effects on neuronal nitric oxide synthase (nNOS) and nitric oxide (NO) levels were also determined by ELISA kits. In light of the data obtained, it was found that pre-treatment with PSO prevented the decrease in cell survival after exposure to PTZ. In addition, it has been found that PSO normalizes the increase in TOS, nNOS, and NO in neuronal cells after PTZ. As a result, it was determined that the treatment of neuronal cells with PSO prevented neuronal damage caused by PTZ and showed neuroprotective properties. It is thought that PSO may achieve these effects through oxidative and nitrosative systems. Enrichment of a daily diet with PSO might be beneficial in reducing the risks of neurological diseases.
