  • Patent number: 8282962
    Abstract: One aspect of the present invention relates to a readily water-dispersible particulate composition comprising by weight of dry matter at least 10% of xanthan gum and not more than 60% of starch, said composition being characterized in that the xanthan gum present in the composition can be dispersed completely within 2 minutes in distilled water of 25° C. at a concentration of 0.7% based on the dry weight of xanthan. The particulate xanthan gum compositions of the present invention exhibit unique viscosity enhancing properties that are dependent on the electrolyte levels of the aqueous environment in which they are applied. The favorable properties of the xanthan compositions according to the invention can be realized without resorting to chemical modification of the xanthan gum. The xanthan compositions according to the present invention can be applied advantageously in e.g. food products and oil drilling fluids.

  • Patent number: 3982003
    Abstract: Food products comprising solid foodstuffs and more especially meat, meat by-products or other proteinaceous materials are contained in an aqueous phase of near neutral pH value thickened or gelled by pectic substances having a degree of esterification (methoxylation) of less than 20%. Where a rigid gel is required the pectic substance is preferably reacted with a di- or tri-valent metal ion, notably calcium ion and also with a sequestrant. The pectic substance may be a purified or isolated pectate or a natural pectin source, for example citrus peel, in which the pectic substance has the required low level of esterification, for example by enzymatic or chemical treatment of the natural material.
