What is Cream?

Cream is a rich, thick emulsion of dairy fat available commercially as a white or light yellow colored fluid or it can be whipped into a stable foam for various applications.

It is popular in baked goods such as:

  • Cakes
  • Pastries
  • Cream filling
  • Custard
  • Frosting

Origin

As far back as 9000 B.C., humans have been breeding animals for milk production. Cream is a dairy product, derived from the milk of cattle or goats. When fresh milk is left unhomogenized, the cream naturally rises to the top due to the lower density (specific gravity) of fat globules. It is then easily skimmed off the top and used for butter, sour cream, or whipping cream.

Composition

Cream is a dairy product consisting of water, protein, lipids, carbohydrates (sugars, including lactose), vitamins, minerals, and other minor components. Various types of cream are distinguished by their butterfat content, processing method whether heat treated, whipped and so on. The fat content ranges from 18-55%.1

Most common additives to cream are:

Some dairy companies add polysorbate to the formula to increase whipping and stability without the addition of stabilizers.

Commercial production

Cream is the fatty liquid that forms a layer on the top of milk prior to homogenization. A process of continuous centrifugation separates cream. The centrifugal force causes natural separation of the fat globules from the milk serum.1 The separated cream is then homogenized and pasteurized or ultra-pasteurized.

When pasteurized, better flavor can develop and the cream whips up with greater fluff. Ultra-pasteurized versions offer an extended shelf life. It has a cooked flavor and is more sensitive to whipping, therefore it is not ideal for recipes that require peaks or frothing.

Function

Cream is commonly used in baked goods to:2

  • Increase moisture absorption
  • Provide lactose which gives browning reaction upon baking
  • Tenderize
  • Serve as a buffering aid
  • Increase protein content and nutritional value
  • Enhance its  foaming ability in cakes and frozen desserts

Applications

Following are some applications of cream in the food industry:

  • As an ingredient in many foods such as ice creams, cakes, sauces, puddings, etc.
  • As a topping in many cakes, pancakes, milkshakes, hot chocolate, fruits, etc.
