Jameed is a traditional dried dairy product in Jordan that is known under different names in the Middle East, Turkey, Central Asia, China, and Mongolia. It has been produced in the region for centuries and makes a significant contribution (up to 20%) to the income of small-scale traditional dairy processors who are based in sheep-producing districts. This study aims to assess the nutritional value of Jameed as a model for traditional dried fermented dairy products and to highlight the safety of the product quality and some of the health risks that may arise. For this purpose, 80 samples of Jameed were collected from the market covering all regions of the Kingdom of Jordan. The samples were analyzed for nutritional value and health risks by standard and approved methods. Results show that the total solids were 84.57%, with a large variation from 73 to 92%. Producers use a lot of salt to control elevated acidity during the drying of Jameed. The salt concentrations in collected samples were 15.68%. The average acidity was 6.79%. Moreover, farmers heavily use antibiotics to control mastitis without observing milk withdrawal. The residues of antibiotics were detected in 50.65% of the analyzed samples. The samples show large variations in measured values, reflecting differences in processing methods, homogeneity, and standardization.

The dairy sector in Tunisia is based on small-scale farms, with 81% of the breeders owning less than five cows. On these farms, milk is stored in plastic containers, resulting in post-production losses estimated at 10% in the studied region. Due to high temperatures, the present paper aims to study the implementation of an innovative solar-powered milk cooling system in Central Tunisia and assess its profitability for dairy farmers. The methodology is based on a comparison of three small-scale farm business models: a farm without any milk cooling equipment, a farm using an innovative milk cooling technology, and a farm using an electrical cooling tank. Results showed the significance of milk cooling in reducing milk rejection to 0%, leading to a total production of 6400 L per cow by the fifth year. Additionally, milk sales were found to increase due to the premium of 0.010 TND/L for cooled milk paid. In addition, farms utilizing solar-powered milk cooling technology exhibited superior profitability in terms of financial indicators. This research offers a sustainable energy solution for milk cooling on small farms, specifically addressing the challenges faced by these farms located in isolated areas where access to electricity is limited and the availability of milk cooling equipment is lacking.
