Exercise 7. Look through the text. Find the answers to the following questions in the text.
1. What is this text about?
2. How do ancient Greeks use milk?
3. When did the large-scale production of dried milk begin?
4. What do we see under the microscope examining milk?
Milk
Milk, when examined under the microscope is seen as a transparent fluid which consists of many minute fat globules suspended together with casein, the main protein of milk, in a solution of albumin, sugar and water. The fat globules in an average drop may number more than one hundred million.
Milk and products derived from milk, such as butter and cheese have been used as food for human beings of all ages throughout the time of recorded history.
The term milk is considered to refer usually to cows milk, since most milk destined for human consumption is from the cow. However, approximately half of the milk consumed in buffalo, and buffaloes of local types produce milk that is used for food in China, Egypt and the Philippine islands.
Goats milk is produced in countries bordering the Mediterranean sea and in small quantities in many other parts of the world. The milk of the reindeer is used as food in Northern Europe; sheep's milk is used in Southern Europe in making cheese.

Cows milk and its products have become important articles of commerce, most of the research on the chemistry, bacteriology and technology of milk being carried out in relation to it.
The ancient Greeks, Romans and Scythians did not use butter as food, but applied it to skin injuries and to the hair, and the soot form burned butter to sore eyes. Butter was used as oil for lamps in Scotland as recently as the 19th century.
Prior to the 17th century, whey was employed widely in Europe as a medicine for many ills. Milk, sugar (lactose) seemed to have displaced whey as a panacea subsequent to its use of lactose has been limited to its function of aiding the growth of desirable bacteria in the intestinal tract. Little is known of the early history of ice-cream.
Commercial processes for making concentrated and dried milks were developed subsequent to 1850.
The original United States patent for evaporated milk was granted to Gail Borden in 1856, and the utility of canned concentrated milk was demonstrated by its use by soldiers in the Civil War a few years later.
F.S. Grimwade's British patent for producing dried milk was issued in 1855, but large-scale production of dried milk did not begin until 50 years later.
