The Quality of Kefir with Honey and with Banana Enriched with Almond Milk
2023
Fatma Çoşkun | Hülya Erol
Kefir is a fermented product obtained from goat, sheep and cow milk as a result of lactic acid and ethyl alcohol fermentation. In this study, it was aimed to investigate the possibility of producing an alternative functional kefir product from almond milk. It was enriched with banana and honey to improve its sensory properties. Samples were stored at +4oC for 14 days. The pH and dry matter of samples containing almond milk were lower than those containing cow’s milk. Serum separation increased with the increase of almond milk ratio. The use of banana increased dry matter and viscosity, and decreased serum separation. pH, dry matter and viscosity decreased during storage. The highest L* value was observed in the control kefir produced from 100% cow’s milk, and the lowest in the samples containing honey and banana on the 1st day of storage. It can be said that the addition of honey increases the b* value and the addition of banana decreases the b* value. As almond milk ratio and storage time increased, bacteria counts decreased. The lactococci counts of the samples with banana added (except for the control) were higher than the others. In the samples with banana and honey, a higher increase in yeast count was observed during storage compared to plain kefir (control sample). It can be said that the use of almond milk reduces the general acceptability of kefir. Almond milk can be successfully used in kefir production as a substitute for cow’s milk, if sweeteners, fruit and thickeners are used.

This study was conducted to evaluate essential oils from Croton macrostachyus Hochst. ex Delile, Eucalyptus globulus Labill., Allium sativum L., Cymbopogon citratus (DC.) Stapf, Cymbopogon martini (Roxb.) W.Watson, Rosmarinus officinalis L. and Thymus schimperi Ronniger using four concentrations (l mL, 2 mL, 3 mL, 4 mL) and three sprays against potato (Solanum tuberosum L.) late blight disease. Two improved potato varieties were planted using randomized complete block design with factorial combinations in three replications. Analysis of disease incidence means at 53 and 60 days after planting showed highly significant differences between varieties and among sources of essential oils. Furthermore, the combined effect of essential oils and potato varieties on disease severity showed significant differences. Disease severity was maintained from 25% to 48% (Jalene); 13% to 30% (Gudene) with essential oils while it was maintained between 92% and 95% (Jalene); 37% to 38% (Gudene) for control plants. The lowest disease percentage of disease severity was obtained on plants treated with A. sativum for Jalene variety while on plants sprayed with C. macrostachyus, E. globulus and T. schimperi for Gudene variety. The lowest disease progress rate 0.198/day and 0.162/day as well as values of area under disease progress curve 228% days and 93% days were obtained for varieties Jalene and Gudene, respectively. Maximum reduction in mean disease severity was exhibited by garlic for varieties Jalene (28.3%) and Gudene (16.3%), as compared to the control (93.3% for Jalene and 37.5% for Gudene). Therefore, results indicated the potentials of essential oils to minimize effects of potato late blight disease. Communities involved in potato production could use the current results as base line information to find alternative management options for late blight disease which has no effect on human health and environment. However, further investigation is required on essential oils affordability and availability to farmers across different locations.

The effect of barium element that can be extremely harmful heavy metal to human and environmental health in urban centers. The barium can cause various environmental pollution due to its anthropogenic accumulation in the environment. Also, it has negative effects on plants, animals, and humans through atmospheric deposition. All Barium (Ba) compounds are harmful heavy metals and they show a poisonous effect on the environment. Thus, it is crucial to determine the Ba concentration in plants grown in areas with high pollution in the landscape, park, and roadside. Biomonitoring with the tree species can be determined which is the best passive biomonitoring method with the tree rings formed by the effect of seasonal differences. The barium has been accumulated in the tree rings for a long time that can provide critical knowledge about the atmospheric barium deposition. The temporal and spatial variations of Ba concentration were analyzed with organs of Ailanthus altissima (Mill.) as biomonitors. This study results show that the outer bark of Ailanthus altissima (Mill.) is a convenient biomonitor for Ba deposition.

Şüheda Atar | Bahri Özsisli
In this study, poppy seed, which is rich in vegetable oil and protein, was added to the traditional Beyşehir tarhana instead of wheat batter. It was aimed to develop a new product and to open a new field for the use poppy seeds. The physical, chemical and sensory features of Beyşehir tarhana that was made with poppy seeds, were analysed. Results of the study; humidity is 6.75% to 7.94%; as his %2.75 to %3.66; salt 1.66% to 1.44%; protein 16.92% to 25.71%; oil 11.99% to 24.03%; pH 4.56 to 5.56; acidity 16.43% to 14.59%; energy 423.13 kcal/100g to 480.36 kcal/100g; carbohydrates 61.9% to 40.3%; were found in these amounts, and they are important. Generally, we see that, most of the people liked the taste of the tarhana sample made with 10% poppy seeds so it has the most points. However, the least liked one was the tarhana sample made with %20 poppy seeds and it has the least points. End of the study, it was observed that the addition of poppy seeds to Beyşehir tarhana affected the chemical, physical and sensory qualities of tarhana positively and it was okay with the standards. (Anonymous, 2004) It was determined that the percentage of poppy seeds suitable for tarhana production was 5% and 10%.

Budding of Pistacia vera L. seedling at the earlier stage of growth with a certain sex type scion is very important because P. vera vegetative growth stage is long and requires more time to produce fruit to determine the sex type of the trees. Therefore, the current experiment was carried out to determine the best time for budding current seedlings of P. vera during late summer. The budding times were 20 Aug., 1 Sept., 10 Sept., and 20 Sept in 2020, and the seedlings were between 5-6 months along budding times. The results revealed that the highest budding success (50%) was achieved from the seedlings budded on 20 September followed by those seedlings budded on 10 September (38.88%). While, budding success percentage was the lowest in the seedlings budded on 20 August and 1 September with the same ratio (27.77%). The longest shoot and the thicker shoot diameter (19.30 cm and 4 mm, respectively) were achieved in the seedlings which budded on 10 September. In contrast, shoot length was the shortest (3.93 cm) in seedlings that were budded on 20 August, and shoot diameter was almost similar (2.39, 2.23 and 2.72 mm) in all seedlings budded on 20 August, 1 September and 10 September, respectively. This study showed that 20 September was the best time for conducting budding of P. vera seedlings which were produced in nursery black bags in the current season.

We, here, aimed to determine the presence of Anguillicola crassus, a swim bladder parasite, in 89 (male: 45, female: 44) dead European eel specimens obtained seasonally between 2020-2021 from a regional fisherman, who has fished with fyke net in the locality Tuzla of Izmir Bay, Eastern Aegean Sea. Out of 21 male European eels caught in winter, only one specimen (TL: 48.5 cm and TW: 247.12 g) had 23 swim bladder parasites (adult nematodes: 15, larvae: 8) and similarly, only one parasite was found in one specimen (TL: 37.5 cm and TW: 88.47 g) of 8 eels caught in spring. No parasite was found in the female eels. At the examinations, it was determined that all adult Anguillicola crassus specimens were females and the minimum-maximum and average length values in adult and larval parasites were, respectively, 1.5-2.5 cm (1.99 ± 0.31) and 0.7-1.3 cm (1.025 ± 2.40). Consequently, the species A. crassus, a swim bladder parasite, was found in European eels from the locality Çamalti Tuzla in two seasons (winter and spring) and this parasitic nematode were only in male eels. This study is a first and remarkable one having evidential value, which shows the presence of the species A. crassus among the eel population in the locality Çamalti Tuzla of Izmir Bay. Besides, it is a population that should be monitored due to the status of Anguilla anguilla on the IUCN red list.

The rapid increase in the world population increases the need for plant and animal food. Agriculture and animal husbandry practices are becoming more common day by day to meet the need for food and to obtain more products. This situation increases the amount of waste per unit of animal products. Increased animal excrement is associated with greenhouse gas emissions, harms the environment and animal health. One of these greenhouse gases, methane, increases animal production and poses a significant threat to global warming. Feeding research, which optimizes rumens and animal productivity to reduce ruminant methane emissions, is one of the hottest topics today. The purpose of this study is to evaluate feed distribution in terms of chemical composition, methane production, net energy, and organic matter digestibility by collecting forage and concentrates from various ranches in Niğde. Therefore, to increase the productivity of livestock on small farms in Turkey, the ratio of feed ingredients was determined on a farm basis, and there were some comments on the lower and upper limits of the fattening rate. Gas and methane production of TMR samples was determined using in vitro gas production technology. Nutrient contents obtained from different livestock farms CP (9.58-14.72), CF (1.89- 2.30), CA (7.64-13.92), ADF (19.77-27.82) NDF (36.71-45.69) DM (90.48-91.79) content, methane (CH₄), OMS, NEL and ME values were also different (P

Meral Kekeçoğlu | Tuğçe Çaprazlı | Emel Çalışkan | Serpil Uğraş
In this study, we aimed to determine the therapeutic value of local Yığılca honeys by examining their physicochemical characteristics, phenolic content, radical scavenging activity, and antimicrobial properties by underlining some overlooked parameters. Honey samples ware divided into two main groups as CH and FH based on melissopalynologycal analysis. Antimicrobial activity of collected honey samples were investigated on important hospital-acquired infections bacteria strains; MRSA (Methicillin-resistant Staphylococcus aureus), MSSA (Methicillin-sensitive Staphylococcus aureus), Escherichia coli, and Acinetobacter baumannii. Although CH’s antimicrobial activities were found slightly higher than the FH’s, there isn’t statistically significant differences between two type honeys. However, the antioxidant activity of CH was found significantly higher than FH. Surprisingly, a higher amount of isomaltose was determined in addition to the total phenolic content in CH compared to FH. There has been found positive correlation between isomaltose amount and zone diameters for MRSA and A. baumannii. We would like to draw attention to isomaltose for its health benefit structure since these parameters may be influence honey’s therapeutic value. We recommend that isomaltose and invertase enzyme should be included in to the honey codex standards suitably depending on the monofloral and multifloral honey’s specific structure, to sensitively standardize and control their quality and therapeutic value. Our data revealed a positive correlation between antioxidant and antimicrobial activity and total phenolic content and higher isomaltose amount.

Eda Adal | Tuğba Aktar
Pomegranate (Punica granatum L.) is a fruit that grows in most tropical and subtropical regions. It has 52% aril, consisting of 78% juice which is used as; juice, molasses, jam, wine, and dried kernels. Potential health benefits increase the demand for the fruit as well as its products. Pomegranate seeds, which consist of approximately 10% of the whole fruit, are a by-product of the juice and juice using products containing nutraceutical functional components such as sterols and punicic acid. Pomegranate seed oil is considered a healthy alternative source of oils, and its production is a valorization process since it is the by-product that usually goes to waste. In the present study, pomegranate seeds were used for oil extraction using the cold solvent extraction method. Oil samples were then taken to the Schaal oven treatment in order to determine changes due to storage. Oil samples were tested for 14 days of total storage at their 1st,3rd, 7th, and 14th days for the oxidation tests, colour, fatty acid composition, and Fourier transform infrared spectra analysis. Data were tested for significance by using statistical analysis. The results indicated that oxidative stability of pomegranate seed oil was decreased by increasing storage time. The studied techniques used in this paper can be valuable processors to monitor the oxidative stability of oils with storage time and evaluate their acceptance on the market.
