Abstract:
Partially derivatized anionic gums are disclosed. The gum derivatives are prepared by reacting non-derivatized gum with quaternary ammonium compounds in less than the stoichiometric amount required for complete derivatization. The partially derived gums are water soluble and resistant to bacterial degradation.
Abstract:
Hydrocolloid/salt blends are prepared which controllably release ions into solution. The blends are especially useful in alginate print paste compositions.
Abstract:
A fermented malt beverage having improved foam stability and desirable lace, cling, and clarity is described. The beverage is stabilized by adding 5-400 ppm by weight of gellan gum.
Abstract:
A composition and its method of use are disclosed for controlling rheology of an aqueous dye, which composition comprises 1-30 parts of a gum selected from the group consisting of xanthan gum, rhamsan gum, welan gum and mixtures thereof and 70-99 parts of a water soluble polysaccharide having aliginate equivalent rheology, preferably an alginate. Also disclosed is a color imparting composition for fabric or carpet printing which comprises 99-99% of an aqueous dye component and 1-10% of the rheology control component. The polysaccharide is preferably an alginate, starch, cellulosic polymer or guar gum or mixtures thereof.
Abstract:
A film forming composition useful as a paper size is described which includes 1-20 parts, preferably 2-15 parts, by weight of a gum selected from the group consisting of xanthan gum, rhamsan gum, welan gum and mixtures thereof; 3-20 parts, preferably 5-17 parts, by weight of a water soluble alginate; and 60-100 parts, preferably 70-90 parts, by weight of starch, polyvinyl alcohol or carboxymethylcellulose, with the gum:alginate ratio being not greater than 1:1, preferably not greater than 1:2. The balance of the composition will primarily be water. Additives such as sodium hexametaphosphate may also be present.
Abstract:
Hydrocolloid/salt blends are prepared which controllably release ions into solution. The blends are especially useful in alginate print paste compositions.
Abstract:
In the printing of dyes onto substrates, the use of a mixed, cross-linked calcium/sodium alginate to thicken the dye solution effectively reduces dye usage.
Abstract:
A fermented malt beverage having improved foam stability and desirable lace, cling, and clarity is described. The beverage is stabilized by adding 5-400 ppm by weight of combined xanthan gum and a cold-water soluble protein.
Abstract:
A fermented malt beverage having improved foam stability and desirable lace, cling, and clarity is described. The beverage is stabilized by adding 5-400 ppm by weight of combined xanthan gum and a galactomannan, e.g., guar gum or locust bean gum, or the glucomannan konjak gum.
Abstract:
Surface sizes comprising 1) gellan gum and 2) one or more film-forming polymers such as chemically modified starch, cellulose derivatives, and polyvinyl alcohol are described. The compositions exhibit enhanced film-forming properties.
