Abstract: The present invention creates a process for treating the surface of fresh meat, in which the meat is treated with a hydrocolloid based on collagen, in particular gelatine, animal glues, collagen, caseins, whey proteins and/or their hydrolysates as well as their mixtures with one another. In particular a weight loss of the meat during storage due to escaping drip is thereby prevented. In the process according to the invention the meat is preferably treated with 0.2 to 1.5 wt % of hydrocolloid, referred to the weight of the meat. It is possible with said process to treat all kinds of meat suitable for human consumption, in particular mammal meat, poultry and fish.

Abstract: A novel biodegradable, water-resistant polymer material which can be produced with defined material properties is suggested, in particular in the form of foils, films, strips, masses, molded articles or the like, this material consisting essentially of a product of the cross-linking reaction of polysaccharides and/or polypeptides, the hydroxyl, amino, imino, thiol and/or carboxyl groups of which are derivatized at least partially in a non-radical reaction with agents which include groups cross-linkable in a process step following the derivatization and separate therefrom.

Abstract: A process for making gelatine films, in particular sheet gelatine, from powdered gelatine includes the following steps: The powdered gelatine with the addition of water is plasticized by the application of shearing forces at an elevated pressure and an elevated temperature, the plasticized mass is pressed in the form of a film through a slotted die, the film is drawn off the slotted die under tension and the taut film is dried.

Abstract: High molecular weight protein/fatty acid condensation products obtained by reaction of one mole of a protein hydrolysate of average molecular mass 3,000 to 7,000 with 0.5 to 3, preferably 2 to 2.5, moles of a C.sub.12 -C.sub.18 -fatty acid chloride in aqueous medium at a pH of 7 to 12. These protein/fatty acid condensation products are distinguished by eliciting no mucosal irritation whatever. They are therefore outstandingly suitable as surfactants for mild washing and cleansing agents.
