The effective shear rate in the Brabender Viscograph has been determined as 40 sec−1 when used for fluids having equivalent Newtonian viscosities in the range 1–30 poise. This shear rate is close to that used in the mouth and implies that rankings of viscosity derived from Brabender readings will agree with sensory consistency judgements. The instrument can, therefore, be reliably used for quality control and be quoted in purchasing specifications. The methodology described can often be used in other situations for assessing an effective shear rate where the geometry of the system precludes calculation e.g. spreadability determinations and extrusion from metal tubes.

Rapid determination of the salt content of cured meat products with a sodium-ion responsive electrode is described and discussed. The method enables the percentage of salt on water content to be measured directly on the meat in a few minutes. Many determinations can be made cheaply and accurately enough for purposes of routine factory control.
