Description

Composition for improving color of guar gum-containing aqueous suspension, preparation method and application thereof Technical Field The invention belongs to the field of suspending agents, and particularly relates to a composition for improving the color of guar gum-containing aqueous suspension, a preparation method and application thereof. Background Suspending agents (also known as "thickeners") are used in a wide variety of applications in various industries, and function to thicken, prevent sagging, suspend, adjust the rheological properties of water, or a combination thereof. Suspending agents are often used in the food industry, in the coating industry, in the biological industry, in pharmaceutical formulations, in vaccine immunization and other industries, and although used in small amounts, they are very effective in improving the viscosity of the aqueous system, increasing the texture and the sense of thickening of the system, or in improving the suspension of solid materials in the aqueous system. While there is also a need for thickening in oil phase systems, thickening in aqueous phase systems is most used and required. Guar gum is a common suspending agent, is a free flowing powder, is generally white to light brown, and has good thickening effect. Structurally, guar gum belongs to nonionic neutral polysaccharide, has a relative molecular weight of 20-30 ten thousand, is soluble in cold water and hot water, and cannot be dissolved by organic solvents. The chemical component of guar gum is galactomannan, and the guar gum and the derivatives thereof have pseudoplastic rheological property like most polymers with relatively high molecular mass, the pseudoplastic property is not as large as that of xanthan gum, and the two suspending agents are usually combined for use in actual use, so that stable dispersion of products such as dairy products and the like is facilitated. Aqueous suspensions formulated with guar gum are generally yellowish green and this color is even more pronounced when the guar gum is mixed with substances such as sodium polyacrylates, which can affect the use of the suspension in certain specific products, for example, in milky white material systems, which can cause the organoleptic properties of the product to be affected, limiting the use of guar gum. Thus, if the colour of the aqueous guar-containing suspension can be eliminated, the range of applicability of guar will be greatly extended.
