In this study, the influence of matrix structure and viscosity was investigated to gain insight into mechanisms sandiness perception. Granules two types resistant starch (RS II III) were used as edible particles different size type II, D4,3 = 21.25 μm; RS III 44.03 μm). First impact adding at levels (1.5 3%) on rheology (flow behaviour) sensory properties (ranking test) custards determined. Sec...

Continuously operated clarifier-thickener units can be modeled by a non-linear, scalar conservation law with a flux that involves two parameters that depend discontinuously on the space variable. This paper presents two numerical schemes for the solution of this equation that have formal second-order accuracy in both the time and space variable. One of the schemes is a standard total variation ...

Primary dermal and eye irritation tests of hydrophobically modified hydroxypropyl methylcellulose (HM-HPMC, hydroxypropyl methylcellulose modified with stearylglycidylether), a new cellulose derivative used as a thickener for topical pharmaceuticals and cosmetics, were conducted in rabbits. A dispersion of HM-HPMC (3%) was applied to intact and abraded skins and reactions were observed. A very ...

Tamarind seed polysaccharide (TSP) obtained from the seed kernel of Tamarindus indica, possesses properties like high viscosity mucilage, broad pH tolerance, no carcinogenicity, mucoadhesive nature, and biocompatibility. It is used as stabilizer, thickener, gelling agent, and binder in food and pharmaceutical industries. The objective of present investigation was to search for a cheap and effec...

The preformulation of insoluble drugs, sulfadiazine and aluminium hydroxyde, were studied in order to achieve a suspension with desirable requirements. The objective of the formulator is to avoid the irreversible aggregation called “caking”, and to obtain a suspension with an airy, large volume sediment easily redispersible and with suitable rheological properties. An experimental design useful...
