Ayse Dilek Atasoy | Mehmet Irfan Yesilnacar | Ali Yildirim | Ahmet Ferit Atasoy
Tea (Camellia sinensis) is one of the most popular nonalcoholic beverages in the world. During tea infusion, both essential mineral elements and toxic metals are extracted into the beverage. In oriental countries, almost a liter of tea is consumed daily by an average adult. Thus, high toxic elements in traditional teas can be of concern. Aim of the study was to determine the essential element contents and toxic heavy metal concentrations in tea products available on the market in Turkey and comparing the contents of infusion for Turkish and Ceylon black and green tea types. The associated health risk to tea drinkers were estimated with reference to Tolerable Daily Intake (TDI) Values from US EPA for adults and children. Among the essential elements in all of the black teas purchased from the market, K was present at the highest concentration followed by Mg, Ca and Al. Pb and Mn contents of several tea samples were found over the Tolerable Daily Intake levels.

Ginger (Zingiber officinale) is one of the important spices in the world. Nepal is the fourth largest producers of ginger in the world, which produced 271.863 MT in 2016. In Nepal, seventy districts are producing ginger and around 400.000 households are involving in the ginger farming which is the chief source of the household income. Moreover, ginger has prioritized by several policies and strategies of the Government of Nepal. This paper examined the production trend and market access of Nepali ginger considering the ginger global market. A diagnostic study of production, value addition, and the marketing system was carried out between the eastern and the western part of Nepal. The secondary information was reviewed and analysed for the study. Likewise, the key informant survey was performed for the primary data and information. For Nepali ginger, India is found constantly top destination. The result of price index suggested that Nepali ginger is losing significant potential earning by not having top most lucrative markets for fresh ginger. Moreover, the trend of the export is ever fluctuating and the result showed that trade of ginger to India in term of export is more stable from the western region as compared to the eastern region. The study found that the major determinants of ginger market access are quality of ginger produced, value addition, level of trade facilitation, and domestic production and the import of India from other countries.

Globally, 16.9% of milk used by humans is taken from different species other than a cow. These species are sheep, horse, yak, ass, goat, camel and buffalo. The global camel (Camelus dromedarius) population is about 34 million head with sharing of almost 0.4% of world’s non-cattle milk. Within the last 20 years, the curiosity of camel farming is amassed remarkably in different countries of the world including the Netherland, Italy and USA for camel milk production. The camel is considered as a goal animal of the 21st century because it produces high quality milk under extreme temperature, deficiency of pasture and dearth of water. The average milk production of camel fluctuates from 4 to 30 lt with lactation length ranges from 9 to18 months having peak yield in second to the third month of lactation. Camel’s milk is used globally because of its salty taste, high vitamin C concentration and its medicinal properties. Nevertheless, it gives many valuable benefits such as treatment of autism, control diabetes and allergy, prevention from liver cirrhosis and replacer of cow milk to avoid an infant’s allergic reaction. The camel milk is a natural treatment of diabetes as it has a substantial result in a decrease of mean blood glucose and conserves necessary insulin doses. Camel milk constitutes of protein (2.5-4.5%), fat (2.9-5.5%), solid not fat (8.9 -14.3%), ash (0.35-0.95%), lactose (2.9-5.8%) and water (86.3-88.5%) as mean specific gravity is 1.03. Due to its distinct properties, the consumption of camel milk is increasing day by day and a number of industries are working to promote camel milk production and processing. Therefore, the tenacity of this review article is to explicate the beneficial uses and production of camel milk over the globe.

Tuba Büyüksırıt Bedir | Hakan Kuleaşan
The use of dried cheese in food production and food preparation sectors is becoming increasingly widespread. Dried cheese is preferred because of their longer shelf life at room temperatures, smaller packaging sizes, practical use, and their ease of homogenization in food products. Various technologies are currently being used for the drying of cheese and efforts are still being made to develop new methods. Freeze drying is a highly preferred technique for the production of dried cheese due to high quality of the final product. Instant removal of water and low process temperatures ensure an effective prevention of chemical and microbial deterioration. In this study, White, Kashar and Tulum cheeses were dried by freeze-drying method. Physicochemical analyses were carried out on the first day in order to determine the initial quality of cheese samples. The moisture and salt content were highest in White cheese, titratable acidity and fat content were highest in Tulum Cheese. Freze dried cheese samples were stored in room conditions for 6 months and changes in microbial populations such as mesophilic aerobic bacteria, yeast and moulds, lactic acid bacteria, Staphylococci spp. and coliform group bacteria were determined. The results showed that Tulum Cheese contained highest microbial counts in general. The number of bacteria was 7.71±0.10 log cfu/g in Tulum Cheese, 5.70±0.07 log cfu/g in White cheese. Total counts of yeasts and molds were 7.37±0.06 log cfu/g for Tulum cheese and 4.92±0.07 log cfu/g for Kashar Cheese. Statistical analysis was performedby using Minitab Statistical Package Program to evaluate the results of microbiological analysis on dried cheese samples.
