摘要:
La présente invention relève du domaine des matériaux multicouches pouvant être utilisé comme emballage. Le but de l'invention est la fourniture d'un matériau à base de matières cellulosiques, recyclable, biosourcé biodégradable, et/ou ayant des propriétés barrières améliorées pouvant être utilisé comme emballage, e.g. dans le secteur alimentaire, et, de préférence, pouvant être produit facilement. En particulier, la présente invention concerne un matériau multicouche comprenant une couche de matériau cellulosique A et une couche de matériau B comprenant au moins une caséine et/ou au moins un caséinate, de l'eau, et au moins un plastifiant différent de l'eau, et, éventuellement de le gélatine. L'invention concerne aussi l'emballage fait à partir de ce matériau, un produit emballé avec cet emballage, et la fabrication de ce matériau.

The present invention provides a method for coating seeds with biological materials such as bacteria, fungi (e.g., yeasts and molds), parasites, recombinant vectors, and viruses. The method comprises (a) applying a moistening liquid to seeds to moisten seeds, wherein the moistening liquid comprises a moistening polymer, and (b) coating the moistened seeds with an effective amount of a dry composition, wherein the dry composition comprises biological materials, one or more disaccharides, one or more oligosaccharides, one or more polysaccharides, one or more carboxylic acid salts, and one or more hydrolyzed proteins. The coated seeds may have an initial water activity (Aw) below 0.4, and the microorganisms on the coated seeds have initial viability of at least 5 logs of colony forming units per gram of seeds (CFU/g seed). Also provided are coated seeds.

Disclosed is an aqueous bonding composition comprises: (A) a saccharide; (B) an inorganic acid ammonium salt; and (C) a metal salt, wherein the metal salt (C) comprises at least one selected from potassium salts, calcium salts, sodium salts, and magnesium salts. The aqueous bonding composition is excellent in balance among bending strength, bending strength under wet condition, water-absorption thickness expansion coefficient, and peeling strength. The aqueous bonding composition can be usefully used to produce a wood-based material. Further, a wood-based material obtainable by using the aqueous bonding composition is provided.
摘要:
A coated product, comprising a substrate (10) and a coating layer (11), wherein said substrate (10) is in shape of a web, sheet or tray of fiber-based material such as paper or paperboard, and wherein said coating layer forma a barrier on the substrate and mainly contains biopolymer material cross-linked by a cross-linking agent, wherein the cross- linking agent is citric acid in a range of 14–50pph, and the biopolymer material is diesterified and hydrolyzed to an extent of less than 80%, preferably less than 50% and most preferred less than 30%.
摘要:
A powdered polymeric coating composition for coating liquid filled beads or capsules comprising modified cellulose, alkali salts of alginate, natural gum, starch, metal oxide, wherein said modified cellulose, alkali salts of alginate, natural gum, starch, metal oxide are present in amounts of 5 to 20%, 60 to 85%, 2 to 12%, 2 to 10%, 0.5 to 5% w/w by weight of the powdered polymeric coating composition and are mixed in ratios ranging from 0.5:8:0.5:0.25:0.1 to 2:15:2:2:1, preferably 1:8:2:0.25:0.1 to 1:12:1 :1:0.2. Also provided are methods for coating and preparing coating liquid filled beads or capsules with the powdered polymeric coating composition.

摘要:
An environment-friendly glue recognised as safe for health, in particular a glue for wood and cellulose materials, is disclosed, as well as its preparation and use. The glue contains as components at least one polysaccharide, lignin sulfonate and an aqueous solvent, or at least one polysaccharide and a lignin sulfonate dissolved in an aqueous solvent. Unlike the known glues based on lignin sulfonate, the glue according to the invention is more resistant to water.
