Kanij Fatema Tuz Zohora | Md. Riyadh Arefin
Tea is the most consumed drink after water as well as is one of the prevalent and the cheapest beverage which consumed globally. Tea is considered a healthy beverage due to the presence of several antioxidants and minerals such as potassium, magnesium, calcium & manganese. Different kinds of teas are manufactured in different countries based on taste, habit and culture of the people. Normally, tea can be categorized into three groups: green tea (unfermented), Oolong tea (partially fermented) and black tea (fully fermented) based on tea processing. Tea is a rich source of polyphenols and now-a-days interest in the possible health benefits of polyphenols, particularly flavonoids, has increased owing to their antioxidant and free-radical scavenging abilities. The rising demand of tea is considered one of the significant components for the worldwide beverage market growth. Tea industry makes a vital contribution to the economy of the respective tea producing countries like China, Japan, India, Sri Lanka, Bangladesh, Kenya etc. At the present time with the rising demand of tea it is needed to emphasize for exploring alternative means of increasing profits from tea cultivation. The tea market price is low in Different countries like Srilanka, India, Bangladesh, Kenya etc. comprises with high cost of production. For this reason, there is no alternatives rather than product diversification of tea through value addition which can be an important approach to mitigate the impacts of low market price and high production costs. This review broadly focuses on the issues leading to the development of wide range of tea and tea product diversification. This paper is also associated health benefits with different types of tea, nutraceutical beverage, confectionary items, toiletries and cosmeceuticals which being commercialized in different parts of the world which are gaining consumer acceptance and also face the challenges of global marketing by tea industries that’s are described in this paper.

The purpose of this study was to estimate and identify factors affecting the willingness of households to pay for conservation of Washera sheep in West Gojam, Ethiopia. This study used both primary and secondary data. A three-stage sampling method was used to collect data from 240 respondents. Data were analyzed using descriptive statistics and econometric models. The two-dimensional test model used a method to determine the choice of the imputation method using double limited dichotomies. The study showed that education level, livestock size, extension contacts and credit source positively affected the maximum household’s willingness to pay for conservation of Washera sheep. On the other hand, age, sex, land size, and the distance of the home from the household’s market have negatively affected the maximum household’s willingness to pay for conservation of Washera sheep. Meanwhile, the total number of valid answers corresponds to 122,168 households. Therefore, the mean willingness to pay for Washera sheep conservation was US$ 3.75 per year and the total economic benefit gain from Washera sheep conservation were equivalent to US$1,069,647.23. The study recommends that households be willing to contribute to the conservation of Washera sheep breed by providing the cash. This ensures community participation in all decision making and formulation of plans and policies related to the conservation of Washera sheep breeds.

In the study; fruit skin color parameters, fruit flesh firmness and total soluable solid (TSS) ratios, as well as total acidity, total phenolic substance, total monomeric anth°Cyanin amounts and total antioxidant capacity were determined. After the fruits were harvested, they were immersed in three different doses (0-2-4%) of calcium chloride (CaCl2) solution for 5 minutes. The fruits removed from the solution were kept to dry. The fruits were stored for 14 days in a cold store with a temperature of 1-2°C and a relative humidity of 90±5%. Before the storage and on the 7th and 14th days of storage, the fruits samples were taken and kept on the shelves in the rooms with a temperature of 21±1°C and a relative humidity of 60±5%for 3 days. Measurements and analyses of fruit quality parameters were made in the samples taken from the fruits that were kept on the shelf for three days. As a result of the study, it was determined that 4%CaCl2 application was effective in maintaining fruit flesh firmness. In fruits kept on the shelf for 3 days after 14 days of storage, SSC of 4%CaCl2 treatment was found to be higher than the control treatment. Compared to the control, 4%CaCl2 caused a significant increase in the total phenol content. The highest total monomeric anth°Cyanin content and total antioxidant capacity was determined in the control treatment. While there were no significant changes in L* values between treatments, a* and b* values were found to be higher in 2%CaCl2 treatment. In the light of the data obtained, it was concluded that 4%CaCl2 application had a positive effect on the shelf life of strawberry fruits.

Verticillium wilt disease in cotton is a soil-borne disease that causes significant yield losses, and it is therefore important to identify disease-resistant genotypes. Current study was carried out in the experimental field of the Faculty of Agriculture, Dicle University (Diyarbakir) in the year 2020 to determine the tolerance levels of some cotton genotypes which contain different characteristics to wilt disease (Verticillium dahliae Kleb.). The experiment area has been naturally infected with Verticillium wilt pathogens. A total of 124 cotton genotypes, including four controls (DP-499, Edessa, ST-468, ES-1), were arranged in five blocks according to the Augmented Design. The indices of stem cross-section and the leaf-disease severity were found significant. The leaf-disease severity varied between 0.12-3.09 at 50-60 % at boll opening period, whilst stem cross-section values ranged between 0.36-2.30. Moreover, a positive correlation was found between the indices. In conclusion, G7, G12, G21, G22, G23, G41, G51, G55, and G101 were determined as tolerant genotypes to Verticillium wilt in terms of examining two parameters.

Eniola Ajibola Olowu | Ian Timothy Riley
Trees in upland, semiarid agroecological zones typically require water efficiency due to low rainfall, cold and dry temperatures as in Niğde Province, Central Anatolia, Türkiye. This study quantitatively assessed farmer perception of ecosystem services and production advantage of trees in a semiarid zone. Forty-nine farmers in Niğde Province were surveyed. The survey evaluated two major factors: ecosystem services and production advantage using eleven indicators. The responses were grouped by age, gender, education, district class (rural and urban) and farm settlement (rural and urban) and were analysed by test of association (χ2) at P≤0.05. Most farmers had knowledge of trees in their environment and mainly supported the perspective that trees were important mainly for cultural and provisioning ecosystem services. However, they held the opinion that having trees on their farmer was a production disadvantage in a semiarid agroecological zone. Although there were no gender differences in their perspectives, there were significant difference by age, education, district class and farm settlement. Farmers in this semiarid agroecological zone seemed more interested in trees with evident ecosystem services and production advantage such as improved crop yield, water efficiency, weed and pest management, ease of harvesting as well as reduced overall production cost. By implication, trees with multiple benefits are required if further planting by farmers is to be encouraged for agroecosystem improvement. In addition, tree choice will be based on farmer perception of the benefits of trees for ecosystem services and production advantage and further research to identify and promote trees that benefits the widest range of agroecosystems.

Hakan Güleç | Fulya Sarper
Using functional foods which are recently a rising value in the food science arouses curiosity in terms of health among people. Honey, as a natural functional food, might play an important role in the increase of this value with a large but conscious use of it in kitchens. Having a prebiotic property with its oligosaccharide components, honey has a characteristic of supporting the increase of probiotic Bifidobacterium and lactobacilli bacteria. In the current study, the culinary status of honey was investigated depending on the views of professional chef trainers. For honey that shows different compositions, chefs point out that, because of the changes of nectars in the flora collected by bees, the qualitative honey bought from local producers could be a more functional food by using it with sauces, milk products like yoghurt and cheese, with such spices as ginger, turmeric, black pepper, and cinnamon at room temperature without an application of heat treatment.

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.

Veysel Doğan | Armağan Hayırlı
Mycotoxin is a worldwide problem threatening animal health and performance as well as public health. The objective of this experiment was to test the effect of ammonization on elimination of common mycotoxins in laying hen compound feed (CF) and dairy cattle total mixed ration (TMR). The CF for laying hens and TMR for dairy cows were contaminated with commonly occurring mycotoxins [aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEA)] at 25 times of their accepted legal limits (20 ppb, 200 ppb and 500 ppb, respectively). They were then subjected to ammonization with ammonium bicarbonate (NH4HCO3) at 50C for 24 hours under the atmospheric pressure. Mycotoxin levels were analyzed using the LC-MS/MS technique. The elimination levels in CF and TMR were 53% and 54% for AFB1; 31% and 31% for OTA and 22% and 22% for ZEA, respectively. In conclusion, ammonization was effective in destroying common mycotoxin, at an order of AFB1 > OTA > ZEA.
