摘要:
The present invention relates to a tubular food casing based on cellulose hydrate which is impregnated and/or coated on its inner surface with a release preparation. The release preparation comprises (a) at least one reactive hydrophobicizing component, (b) at least one non-reactive release component and (c) at least one oil component and/or lecithin component.

The invention relates to edible molded bodies in the form of a flat or tubular film based on plastifiable biopolymers, the cleavage products or derivatives thereof and/or synthetic polymers from natural monomers, characterized in that they are produced according to a method comprising the following steps: a) the biopolymers, cleavage products or derivatives thereof and/or synthetic polymers are mixed with at least one edible plasticizer, at least one lubricating agent and at least one cross-linking agent, b) the mixture thus obtained is melted into a thermoplastic material, c) said material is extruded and d) the product obtained by extrusion is calendered and/or stretched or blown and deformed into the edible molded body. The molded bodies cited in the invention are suitable for use as food wrappers for sausages and boiled ham, and are particularly suitable for use as seamless sausage casings.
摘要:
The invention relates to a film which is produced form a thermoplastic polymer mixture containing the following: a) thermoplastic starch and/or a thermoplastic starch derivative and b) at least one polyester urethane, with the weight ratio a):b) being in the range from 75:25 to 5:95, and the surface-related degree of stretching the film being 2 to 70. The polyester urethanes forms a matrix in the mixture and the thermoplastic starch or a thermoplastic starch derivative being distributed in a microdispersion in the form of particles with a diameter dp of 0.05 to 30 &mgr;m. The invention also relates to a method for the inventive film and its use as a packaging film, especially for artificial sausage skins.
摘要:
The present invention relates to a method for the production of a quickly wettable material containing natural hydrocolloid in the form of a shaped body, in which a material containing natural hydrocolloid in the form of a shaped body is exposed to a plasma.
摘要:
The present invention relates to a composite biomaterial and a process for producing a composite biomaterial with controlled release of active ingredients, comprising a three-dimensional polymer-based support structure, and a polymer-based matrix structure. The active ingredients are in this case incorporated into the composite biomaterial via the matrix structure, and the composite biomaterial is obtainable by introducing the matrix structure into the support structure. The active ingredients may in this case be incorporated for example adhesively, via specific binder molecules or via enzyme-labile linker molecules via the matrix structure into the composite biomaterial.
摘要:
An oriented film composed of thermoplastic polymers is described which comprises at least one vacuole-containing layer. The vacuole-containing layer comprises particulate hollow bodies which are essentially composed of a polymer which is incompatible with the thermoplastic polymer. A process for producing the film is also described.
摘要:
Nanoparticles containing an active substance and a ketalized polytartramidic acid, process for their preparation, and use thereof. Nanoparticles containing an active substance and a ketalized polytartramidic acid are suitable as vehicles for active substances, in particular for peptides and proteins. Processes for the preparation of the nanoparticles are described.
摘要:
The aim of the invention is to obtain a food product, in particular a snack product, which has a favourable nutrient physiology and a crispy, brittle texture, and an associated production method. To achieve this, the food product is substantially devoid of starch and has a foamed structure and the solid content has a protein fraction of at least approximately 25% by weight, at least 65% by weight of the protein fraction consisting of gelatin and/or collagen hydrolysate.
摘要:
Shaped bodies based on gelatin which have both high mechanical strength and also sufficient flexibility are provided, the shaped body comprising a cross-linked, gelatinous material which comprises gelatin and a plasticizer, the shaped body being stretched so that the gelatin molecules are oriented at least in part in a preferred direction.
摘要:
To provide an ink jet recording material wherein, in particular, the problem of light fastness of the prints, i.e., the oxidative decomposition of the organic dyes in the inks, is eliminated, the use of chitosan or a derivative thereof is proposed as color-fixing agent in a color-receiving layer of ink jet recording materials.
