Contribution

It provides new insights into the complex heterogeneous structure of crumpled cream layers using noninvasive imaging techniques.

Findings

Low volume fraction in crumpled cream layers

Presence of anomalous fractal dimensions

Effective use of NMR imaging for structural analysis

Abstract

The cream layer is a complex heterogeneous material of biological origin which forms spontaneously at the air-milk interface. Here, it is studied the crumpling of a single cream layer packing under its own weight at room temperature in three-dimensional space. The structure obtained in these circumstances has low volume fraction and anomalous fractal dimensions. Direct means and noninvasive NMR imaging technique are used to investigate the internal and external structure of these systems.
