Consistency of Margarine and Other Plant-Based Edible Fats
The penetrometer PNR 12 is suitable for consistency measurements required in the food industry. Various accessories and test kits according to the AOCS and the Unilever method are available for margarine and other plant-based edible fats.
This Application Report describes how the consistency of margarine and other edible fats is measured and classified with Anton Paar’s penetrometer PNR 12 according to the AOCS and the Unilever method.
The PNR 12 is a gravity penetrometer and measures the resistance a material provides against being pierced by a specifically shaped test body. A needle-shaped or conical test body is lowered precisely to the sample surface, and then sinks into the material by its own weight during a defined period of time. This penetration which is indicated in penetration units (PU) or directly in millimeters allows a rating of the plasticity or consistency.
Due to its easy handling and convertibility the penetrometer PNR 12 has gained a wide scope of application. It is an ideal solution for consistency tests of margarine and other plant-based edible fats.
