Abstract

Recently reported results for the behaviour of fluidized beds under extreme conditions of operation are shown to be in good quantitative agreement with the predictions of a long established fluid‐dynamic criterion for the onset of instability of the homogeneously fluidized state. The four sets of experiments relate to fluidization under very high pressure conditions (by supercritical fluids), at very high and very low effective gravitational field strengths, and at very low particle concentrations.

The stability of lutein, a major xanthophyll, was investigated under various storage conditions. Continuous exposure of lutein-containing samples to cold white fluorescent light (4600 lux) at 25 "C resulted in the degradation of lutein at 0.8% -10.7% per day in the samples containing ascorbic acid,
