Industrially, the yield stress is an established, product related phenomenon used to describe 'structure' within a given system. It is used, primarily as a descriptor of product behaviour and hence, quality under specific circumstances. This paper examines an alternative view of stability with respect to fruit suspension. The samples have all been subjected to different shear histories. Flow curves are presented, together with fits for the Carreau model. The systems stability is expressed qualitatively as a function of the gravitational stress of the particle and the stress corresponding to the onset of shear thinning. Quantitatively, the stability is expressed as a Stokes law velocity.
