Cheese is perhaps the first food to be manufactured that is currently consumed by humans. The oldest written records have references to cheese S1.______ as a food. Today, cheese is available in an almost numerable variety of kinds, flavors and consistencies. Cheese is made by many different races of S2.______ people under wide varying conditions all over tide face of the earth. And the S3.______ peoples who eat it like the various flavors and consistencies produced. S4.______ For the better understanding of the art and sciences of cheese-making S5.______ one needs to know what kind of product it is and how the manufacturer pro- cedures developed over the years. Even though the varieties differ quite widely in composition, cheese can be characterized as a product made from S6.______ milk in that the protein is coagulated and concentrated. S7.______ For centuries, cheese-making has been a farm and home industry with the individual producers using surplus milk to make small batches of cheese. Goat cheese making in the US still follows this general practice. It S8.______ was, and still is to a considerate degree, an art; since the middle of the 19th century, however, more and more cheese has been made in specially equipped factories with greater application of science in the manufacturing procedure. Milk from all species has been used for cheese making. Be- S9.______ cause more attention has been given with increasing the productivity of the bovine species, a large proportion of commercial cheese is now made from S10.______ cow milk; the milk from the buffalo, zebu, sheep and goats is also used extensively. 【S1】
