（Start at 59"This is Bill White with the VOA Special English AGRICULTURE REPORT.
(1)Camels have carried people and their goods for centuries. However, camels do more than provide transportation across deserts.
People in desert areas use camel hair to make (2)rugs, (3)temporary housing and clothes. They burn the solid waste from the animals for (4)fuel. People also use camels for meat and milk in areas where growing food is difficult.
However, camel milk is rarely made into cheese, a food made from the milk of other animals. One reason is that camel milk is more difficult to (5)curdle² or thicken than other kinds of milk. The United Nations Food and Agriculture Organization is helping³ people solve the problem.
The main goal in cheese-making is to get the milk to form curds⁴ and whey. Curd¹ is a soft (6)substance made from treated milk. The curd contains a liquid called (7)whey. The whey must be (8)expelled from the curd before cheese is made.
Modern cheese-making methods help the curdling⁵ process by adding a bacterial⁶ substance or starter. The starter produces (9)lactic acid and (10)rennet, a substance from cows that contains a special (11)enzyme⁷. The enzyme speeds up the separation of liquids and solids. Camel milk is different from other kinds of milk because traditional rennet does not affect it.
F-A-O officials say fifty percent of camel milk is wasted in some cultures because people use it only as a fresh drink. They say making cheese is a way to save milk and create a product for use in trade.
Several years ago, the F-A-O ordered a study of the problem. J.P. Ramet is a French agricultural expert. Mister Ramet carried out experiments in Saudi Arabia and Tunisia. He found a way to curdle camel milk by adding the chemical (12)calcium (13)phosphate and vegetable rennet.
The next step was to see how camel cheese production might work. In Nineteen-Ninety-Four, the F-A-O began assisting a milk production center in (14)Mauritania with camel cheese production. F-A-O officials provided technical help and machinery⁸. The milk center successfully produced camel cheese. However, many Mauritanians are not used to eating cheese. So only small amounts of the camel cheese are being sold in Mauritania’s capital.
F-A-O officials believe the technology for making camel cheese could help many people in desert areas.
