摘要:
The invention concerns a composition for providing a substrate, after said substrate has been coated, with barrier properties to oils and greases, and complementarily to water. The invention is characterised in that it is obtainable by dispersion, at a temperature ranging between room temperature and about 70null C., of at least a film-forming gum or resin, not water-soluble and solubilized in at least a water-miscible solvent, in an aqueous solution containing at least a water soluble and lipophobic film-forming compound selected among proteins, polysaccharides and their mixtures, said composition having a temperature ranging between room temperature and about 70null C. The invention also concerns a method for preparing said composition, kits containing same, and a method for providing a substrate with barrier properties, and their uses, in particular for making packages and particularly packages for foodstuff.
摘要:
A composition for reducing the buildup of snow and ice on a surface. The composition includes a sugar-water mixture having approximately 15 to 80 percent by weight of a sugar solid, wherein the sugar solid contains approximately 2-60 percent by weight of a monosaccharide.

This invention relates to a biomolecule-bound substrate made of polymeric molecules, each of which contains a reacting group; and a plurality of biomolecules, each of which contains another reacting group. One of the two reacting groups is a substitute group and the other is a leaving group; and the biomolecules are covalently bonded to the solid support via a chemical ligation reaction between the two reacting groups.

A recording paper coated or impregnated with a sizing agent containing a water-soluble soybean polysaccharide as an indispensable component, and optionally a cationic polymer and a surfactant, preferably a nonionic surfactant having HLB of 5-15. The water-soluble soybean polysaccharide is a water-soluble polysaccharide extracted from soybean or soybean extraction residue and subjected to desalinating purification.

The invention relates to fiber compositions that can be pumped and metered in the fashion of fluid chemical admixtures into a concrete mix, thereby enabling the fibers to be dispensed by concrete ready-mix plant operators who can provide verification of fiber administration and dosage. The fibers, particularly plastic shrinkage control fibers having large cumulative surface area, are suspended in an aqueous medium such that their surface area is already wetted out, thereby virtually assuring that substantial uniform fiber dispersion can be achieved without clumping and the delay that is usually required by fiber intermixing.
摘要:
Disclosed is a method for modifying naturally occuring biocompatible biopolymers of plant and animal origin by subjecting same to ionizing radiation in the presence of a mediating gas, typically acetylene to enable one to selectively enhance and modify one or more of the physiochemical propserties of the starting materials which have a wide range of uses in medicine, food technology and other industrial applications. Notwithstanding the modifications, the biocompatibility of the biopolymer remains unchanged and no new or additional functional groups are introduced into the starting biopolymer.
摘要:
An edible, hardenable coating composition is disclosed which comprises high levels of low viscosity propylene glycol alginate and a surfactant, which may additionally contain a filler, a pigment, and optionally a small amount of a secondary film former and/or a strengthening polymer. The coating composition of the present invention may be applied to pharmaceutical and veterinary solid dosage forms, confectionery, seeds, animal feed, fertilizers, pesticide tablets, and foods and provides an elegant prompt release coating which does not retard the release of active ingredients from the coated substrate.
摘要:
The invention is directed to a co-crystallized product and a method of making the product. The product comprises a polyol and a hydrogenated maltodextrin that have been co-crystallized together. The co-crystallization of polyols and hydrogenated maltodextrin according to the invention provides a sweetener product that is sucrose-free, yet has a reduced sensory cooling effect compared to the original polyol(s). The reduced sensory cooling effect is due to an increase of the heat of solution that is observed when polyols are co-crystallized with hydrogenated maltodextrin. Because the product of the invention is a sucrose-free sweetener that does not demonstrate the strong sensory cooling effect typically found with polyol sweeteners, the invention has a wide variety of applications which previously are not available for polyol sweeteners.

The present disclosure provides a decorative stain and/or coating composition which can be applied, using conventional, low-cost techniques to concrete, masonry or like material surfaces in order to provide an desired aesthetic appearance to such surfaces. The methods of use taught herein do not require expensive and laborious pre-treatment, such as cleaning and restoration, as well as handling/disposal concerns typically associated with acid-utilizing stains and decorative coatings and sealers.
摘要:
Disclosed is a hybrid protein-polysaccharide superabsorbent hydrogel. The hydrogel includes two interpenetrating matrices: a first matrix which is an acylated, cross-linked protein matrix, and a second matrix which is an anionic polysaccharide matrix. The two matrices can be non-cross-linked, or the hydrogel can further include bridging moieties that covalently cross-linking the acylated, cross-linked protein matrix to the anionic polysaccharide matrix.
