The present invention relates to a process of compacting a microporous fat powder, notably a microporous fat powder that can suitably be used as an oil structuring agent. One aspect of the invention relates to a process for compacting a microporous fat powder, said process comprising: feeding the fat powder into the feed zone of an extruder having a forwarding screw and a barrel within which said screw is centrally positioned rotating said forwarding screw to advance said fat powder feed through a compacting zone of the extruder where the barrel comprises a plurality of venting openings having a shorter dimension that exceeds the volume weighted average diameter of the fat powder feed and that is less than 10mm and expelling the compacted fat powder from the extruder wherein the temperature of the fat powder during passage through the extruder is maintained below 40°C and wherein the compaction factor achieved exceeds 1.5 Another aspect of the invention relates to a compacted microporous fat powder having the following characteristics: a freely settled density in the range of 90-600 g/l a particle size distribution with at least 90 vol.% of the particles having a diameter in the range of 20 to 600 μm a maximum Gi /Gd ratio of more than 2.0, wherein G represents the elastic modulus at 10 C of a dispersion of 2 wt.% of the compacted fat powder in glycerol, and wherein the maximum ratio is determined by recording Gi whilst increasing the frequency from 0.1 to 15 s-1, by subsequently recording Gd whilst decreasing said frequency from 15 to 0.1 s- 1, and by calculating the ratio Gi /Gd at the frequency at which said ratio is highest.La presente invención se relaciona a un proceso para compactar un polvo de grasa microporoso, notablemente un polvo de grasa microporoso que puede ser usado adecuadamente como un agente estructurante de aceite.
