Abstract
Orange concentrate, at the 60‐65° Brix concentration level, is a non‐Newtonian fluid with yield stress and time dependent behaviour. While recovery from low‐rate shear is reversible, shear at high rate causes irreversible destruction of the viscous structure. Part of this effect is due to disintegration of pulp particles. Pulpless concentrate (serum) is also non‐Newtonian, but yield stress and time dependent behaviour are present only when pectin concentration is high. Depectinized serum is Newtonian. The effect of temperature on flow properties of all three types of material was studied.Keywords
