Fluid contaminants may be prevalent in many industries, such as the mining industry. Functionalized saccharide polymers comprising two or more monosaccharide units linked by glycosidic bonds and having a portion of the monosaccharide units oxidatively opened and functionalized with at least one aminocarboxylic acid covalently bound through nitrogen at a site of oxidative opening may be utilized in conjunction with fluid remediation processes, such as froth flotation. In non-limiting examples, the functionalized saccharide polymers may also be useful for promoting dust control, particulate coating, clay stabilization, and various subterranean treatment operations. Glycine represents one example of an aminocarboxylic acid that may be covalently bonded through nitrogen at a site of oxidative opening.

The present invention includes a hydrogel and a method of making a porous hydrogel by preparing an aqueous mixture of an uncrosslinked polymer and a crystallizable molecule; casting the mixture into a vessel; allowing the cast mixture to dry to form an amorphous hydrogel film; seeding the cast mixture with a seed crystal of the crystallizable molecule; growing the crystallizable molecule into a crystal structure within the uncrosslinked polymer; crosslinking the polymer around the crystal structure under conditions in which the crystal structure within the crosslinked polymer is maintained; and dissolving the crystals within the crosslinked polymer to form the porous hydrogel.

An okra polygalacturonic acid having a uric acid-lowering effect, a method for preparing the same, and use of the same are disclosed. The method includes: smashing an okra, lixiviating the okra in ethanol, and filtering to obtain a filtrate and a residue; removing the filtrate, and lixiviating the residue in heated water to obtain an extraction solution; adding the ethanol into the extraction solution to precipitate okra crude polysaccharides; purifying the okra crude polysaccharides over an anion exchange column by eluting with water or a NaCl solution, a Tris-HCl solution or a NaCl-containing Tris-HCl solution, or a phosphate solution or a NaCl-containing phosphate solution, and collecting a fraction eluted by the NaCl solution, the NaCl-containing Tris-HCl solution, or the NaCl-containing phosphate solution; and concentrating, dialyzing and drying the fraction to obtain the okra polygalacturonic acid.

Disclosed is a method for regulating a porous structure and texture property of a freeze-dried pectin aerogel, which comprises the following steps of step 1: preparation of pectin/starch solution by mixing pectin powder and a gelatinized starch solution to form a stable pectin/starch mixed solution, a concentration of the pectin being 0.05% to 0.2% (w/v); step 2: induction of gel reaction by adding D-(+)-Glucono-δ-lactone and calcium carbonate into the stable pectin-starch mixed solution; and step 3: vacuum freeze of the starch/pectin composite gel subjected to the gel reaction to obtain the freeze-dried pectin/starch aerogel with an adjustable porous structure and an improved texture characteristic. Controllable regulation of the porous structure of the freeze-dried pectin aerogel is achieved by the method without complex pretreatment. Raw material ingredients applied in the method are cheap, easy-to-access, and has low-toxicity.

The present document describes a process for the preparation of a low functionalization polysaccharide having carboxyl groups, comprising a) swelling of a polysaccharide granule in boiling water or a water/polyol mixture, to obtain a swollen polysaccharide; b) partial gelatinization of said swollen polysaccharide in an alkaline solvent mixture of water and alcohol and/or polyol, to obtain a partially gelatinized polysaccharide; and c) partial functionalization of said partially gelatinized polysaccharide with a functionalizing agent, to obtain the low functionalization polysaccharide.
