Particle size distribution. Ice cream mixes and melted frozen
ice cream (allowed to melt at 5 ◦C for 24 h) were analyzed by
diluting a single drop of mix in the sample chamber of the Mastersizer
2000 (Malvern Instruments, Malvern, Worcs, U.K.) in the
proportion of 1:1000 (mix/water). The refractive index of RBW oleogel was determined to be 1.474 (J357 Automatic Refractometer,
Rudolph Research Analytical, Hackettstown, N.J., U.S.A.).
