51 Introduction to Dairy Products
Learning Objectives
- Identify and describe milk and dairy products used in the food service industry
- Describe the production of milk and dairy products
- Describe the function of milk and dairy products in baking
Milk and milk products are some of our oldest and best-known natural foods. In baking, milk is used fresh, condensed, powdered, skimmed, or whole. The great bulk, weight, and perishability of fresh milk plus the expense of refrigeration makes it a relatively high-cost ingredient, and for this reason, most modern bakeries use non-fat powdered milk or buttermilk powder.
Over the past 20 years, there has been a trend to lower fat content in dairy products. This reflects the high caloric value of milk fat, and also is compatible with the trend to leaner, healthier nutrition. These “low-fat” products often have the fat replaced with sugars, so care must be taking in substituting these ingredients in a recipe. For bakers, this trend has not meant any great changes in formulas: a 35% milk fat or a 15% cream cheese product usually works equally well in a cheesecake. Some pastry chefs find lowering the richness in pastries and plated desserts can make them more enjoyable, especially after a large meal.
Table 15 provides the nutritional properties of milk products.
