They do not contain lactose and therefore are commonly described as not being dairy products, although many contain casein, a milk-derived protein. Dry granular products do not need to be refrigerated and can be used and stored in locations which do not have a refrigerator. Liquid non-dairy creamers should be tightly capped and refrigerated after opening. Some non-dairy creamers contain sweeteners and flavours, such as vanilla, hazelnut or Irish cream. As with other processed food products, low calorie and low fat versions are available for non-dairy creamers.
