摘要
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 10 mm; andexpelling 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 G′i/G′d 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 G′i whilst increasing the frequency from 0.1 to 15 s−1, by subsequently recording G′d whilst decreasing said frequency from 15 to 0.1 s−1, and by calculating the ratio G′i/G′d at the frequency at which said ratio is highest.展开▼
