2022
Talip Cakmakci | Ozlem Cakmakci | Ustun Sahin
Salinity often increases osmotic stress, reducing plant water uptake and inhibiting the absorption of nutrients and minerals. This imbalance situation causes physiological, biochemical disorders, and nutrient deficiencies in plants. In this study, the effects of biochar application on the physiological properties, nutrient contents and antioxidant enzyme activities of lettuce were investigated under saline irrigation water conditions. For this purpose, four different biochar doses and different irrigation water salinity levels were applied to the lettuce plant. In the study, biochar application under salt stress conditions decreased the Na, Fe, Zn content and antioxidant enzyme activity of the plant. Leaf relative water content, chlorophyll content (SPAD) and some nutrients (Ca, K, Mg, P, Cu and Mn) also increased. Therefore, biochar applied under salt irrigated water conditions offers good potential to reduce the severity of plant exposure to salinity stress. In addition, the biochar amendment helped the plant uptake of nutrients.

The effect of cricket addition on the proximate composition, mineral compositions, functional and sensory properties of complementary food formulated from millet was studied. The result of the chemical composition showed significantly increase in the protein and fat level of the formulated complementary food (9.28±0.16 - 20.20±0.07) % and (3.65±002 - 8.12±0.08) %, respectively. However, a significant decrease in the carbohydrate level (75.61±0.03 - 60.44±0.31) g/100g was observed. Evaluation of functional properties showed that cricket addition did not affect the bulk density but increased the water absorption (2.46±0.05), Emulsion (38.02±0.40%), foam (6.00±0.00), gelation (20.00±0.00%) capacities and pH (6.20±0.02). The mineral contents including Fe, Ca, Na, and K of the food ranged from 7.54±0.10 - 10.25±0.05 mL/100g, 30.35±0.15 - 34.98±0.10 mL/100g, 9.35±0.29 - 14.47±0.06 mL/100g and 30.92±0.03 - 56.40±010 mL/100g respectively increasing with increased addition of cricket flour The formulated samples were rated higher for taste, colour, flavour, texture and the overall acceptability than the control. In general sample 513 containing 75:25 cricket: millet flour showed more improvement than other formulated samples and most acceptable in terms of taste, flavour mouth feel and overall acceptability. Adding cricket flour to millet flour as complementary food would help in addressing protein energy malnutrition in children.

This study was conducted to assess variability among linear body measurements (LBMs), deduce components that describe these traits, and investigate the inter-relationship among them. For this purpose, seventeen LBM traits namely heart girth, body-length, wither-height, ear-length, forelimb-length, hindlimb-length, barrel-girth, face-length, hip-width, chest-width, chest-depth, tail-length, neck-length, hump-length, hump-circumference, forehoof-circumference and hindhoof-circumference were measured on 300 (51 males and 249 females) camels. PC factor analysis was used to describe the variation in LBM traits where extracted factors were varimax rotated to enhance interpretability. Pearson’s correlation coefficients among the traits were positive and very highly significant. From the factor analysis, two principal components (PCs) were extracted, which accounted for 63.2% of the total variance. PC1 accounted for 57.0% of the total observed variance and was loaded by EL, BL, FL, HL, FLL, WH, CD, NL, and HC; while PC2 contributed 6.1% of the total observed variance and had its loading on HG, BG, and HW. The results obtained from this study could be useful in designing appropriate husbandry, selection, and breeding programs for utilization of camel genetic resources.

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.

Turkey is the largest hazelnut producer, and the Trabzon is one of the important provinces with an annual production of 47.000 tons. The citrus longhorned beetle [Anoplophora chinensis (Forster, 1771) (Coleoptera: Cerambycidae)] is not an indigenous pest to Turkey. It is a poliphagous woodboring beetle with a large host range including ornamental plants and fruit trees such as Citrus and Corylus. The insect was intercepted for the first time on maple and willow plants in a nursery in Istanbul in 2014. Domestic trade of those plants caused the spread of the insect from Istanbul to Trabzon in 2016. Since then, the insect has been spreading at speed in villages of Maçka district. However, the spread of the insect could have not been prevented. The insect was detected in 250 ha in 2020, but the area enlarged to 409 ha in 2021. Quarantine measures and eradication studies have been applied in the region that chemicals were sprayed and infested plants were destroyed. Currently, hazelnut orchards of 286 ha were dismantled and more than 172,000 ocaks were removed and destroyed in Akmescit, Alaçam, Armağan, Bahçekaya, Durali, Esiroğlu, Günay, Hızarlı, Işıklar, Öğütlü and Temelli villages. To compensate the losses, objective yield estimates were made by the Ministry of Agriculture and Forestry officials and 2.6 $ per kg was set to pay to the growers for the period of 4 years. By the end of 2021, 539 growers were paid of about 1.975,000 $ for compensation. Although the infestation and the spread of the insect is monitored it poses a real threat to hazelnut sector in the Black Sea region.

The world population growth has increased demand for traditional protein sources but an alternative protein source was sought due to limited land. Edible insects containing all the essential amino acids in a healthy diet are sustainable and promising alternative protein source. The protein content of insects varies in a wide range depending on the type of insect and the stage of development (13%-77%). Some edible insects are currently consumed by two billion people worldwide. In the literature, more than 2100 insect species have been recorded as edible. The sensory attributes of edible insects are an important factor that can accelerate their acceptance by consumers. Generally, the taste of insects is described as nutty and largely depends on the cooking technique. Potential food safety risks of edible insects can be microbiological, parasitological and allergenic. This review has been shown to be a healthy food source with high protein content, lipids, vitamins, minerals and fiber, the nutritional composition and functionality are compared between different insect species, and information on the sensory quality and risks of insect eating is presented.

Truffles are a highly valued fungi group because of their gastronomic and economic importance. Even though the demands for truffles, particularly Tuber melanosporum and T. aestivum, has been increased year by year, the natural production of these valued fungi has decreased. So, truffle cultivation is becoming an agricultural alternative in Europe, and the rural economy was supported by cultivating truffle. In Turkey, truffle cultivation was becoming popular in recent years. However, there is not enough literature for understanding the basics of truffle cultivation in Turkey. Hence, it is aimed to discuss the selection of suitable truffle land. Because land selection can be considered as the first step of truffle cultivation and unsuitable land can be limited truffle cultivation success. So, the ecological features of economically important truffles, T. aestivum, T. borchii, T. magnatum, and T. melanosporum, are given in this study based on current literature and field experience.
Mostrar más [+] Menos [-]Use of Membrane Separation Techniques in Dairy Technology and Its Effects on Dairy Products Texto completo

Merve Özcan | Ece Büyükgümüş | Selda Bulca
Membrane separation techniques are used to separate certain components (protein, fat, water, etc.) in liquid products such as milk and to obtain these components in pure form, and also to remove microorganisms in these liquid products. In addition, these techniques are used to concentrate milk in the dairy industry. In membrane separation, components pass through pores of a certain size and are separated according to molecular weights. The basic principle in separation techniques is based on the fact that the liquid is passed through the pores of the membrane under certain pressure, the desired components (retantat) are kept in the pores and other components (permeate) pass through the membrane. The techniques used are grouped into four main categories: Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and hyperfiltration (reverse osmosis). Among the advantages of the membrane separation technique are the low electricity consumption, the possibility of use in various areas, and the fact that it does not cause undesired changes in the product characteristics. There are disadvantages such as the cost of initial installation, fouling of the membrane pores, and the membrane cleaning takes a long time.
