Text A.
Milk products used in ice cream
Whole milk is very desirable as a source of fat as well as of milk solids-not-fat. Only of clean flavour and odour, with low acidity of 0,2 per cent or less, should be used. A combination of milk and sweet cream is probably the best source of fat for ice cream. Fresh whole milk is seldom used because in many markets it is too expensive as a source of fat and milk solids-not-fat. Fresh sweet cream is the most desirable concentrated source of butterfat for use in the mix. Other concentrated milk products do not impart the same clean, rich, creamy flavour that is carried by a good quality sweet cream. Cream concentrating 40 per cent fat should not exceed 0,15 per cent acidity and should be free from off-flavours and odours. But sweet cream is relatively expensive as a source of fat and is difficult to secure in good quality at certain seasons of the year on some markets. Frozen cream is stored by many companies during the months of surplus and low price. Only the best fresh cream should be used for storing frozen cream. It should be pasteurized at 165° to 175° F for 15 minutes to inhibit the development of off-flavours. Neither the milk nor the cream should come into contact with exposed iron and copper. Copper, iron and bronze may dissolve in the cream, producing a tallowy and metallic flavour during storage of the frozen cream. In frozen cream certain off-flavours may develop, such as rancid, fishy, oily and tallowy ones. When we store cream for use in ice cream we must bear in mind that the addition of 10 per cent by weight of cane sugar is necessary. Fresh skim milk should be used in the mix, because it is a cheap source of milk solids-not-fat. It should have a low acidity and a clean flavour. A 40-quart can of skim milk will contain about 7,5 Ibs. of milk solids-not-fat.

Exercise 14. Read Text B attentively.
Text B.
Unsalted butter (sweet butter) is next to sweet cream in importance as a source of fat. The advantages of butter are such that it is a comparatively cheap source of fat; it can be transported at low cost, can be stored for months with little deterioration in quality and is nearly always available in fairly uniform quality.
Non-fat dry milk is one of the concentrated solids-not-fat which frequently used. There are three forms of non-fat dry milk on the market: spray process powder, drum-dried powder and flakes. Each contains over 90 per cent milk solids-not-fat. Non-fat dry milk should be bought only in such quantities as can be used before the product develops off-flavours and preferably should be kept in cold storage.
Plain condensed skim milk is used more frequently than any of other condensed milk products. The keeping quality of condensed skim milk is only a little better than that of cream. Condensed skim milk varies from 25 to 35 per cent in milk solids-not-fat.
