7.3 Methods of examination
7.3.1 Determination of the dry matter (dm)
7.3.1.1 Principle
The dry matter is the sum of all non-volatile components in a food, such as lipids,
carbohydrates, proteins and minerals. The mass loss of the sample is determined by
drying to constant weight in a drying oven at 105 °C.
7.3.1.2 Equipment and materials
• Analytical balance, accuracy: ± 0.1 mg (Sartorius AG, Germany, BP210S)
• Drying oven 105 °C (Loading Modell 100 - 800, Memmert GmbH & Co. KG,
Germany)
