    • Antimicrobial film based on biopolymers, in particular cellulose and/or protein, or uncoated or coated textile material, and also an antimicrobial sponge or an antimicrobial sponge cloth based on regenerated or precipitated cellulose are provided. The film, the sponge or the sponge cloth is impregnated or coated with at least one α-amino acid ester, the α-amino group of which is acylated with a fatty acid, or the corresponding hydrochloride, and the α-amino acid ester is bound covalently, optionally also ionically, to the film, the sponge or the sponge cloth. The acylated α-amino acid ester is preferably N-lauroyl-L-arginine ethyl ester monohydrochloride (LAECI), N-lauroyl-L-arginine methyl ester monohydrochloride (LAMCI) or N-lauroyl-L-lysine ethyl ester hydrochloride (LLECI). The film is preferably in the form of a flexible tube and is provided as casing for foods, especially sausage products.
    • 提供了基于生物聚合物,特别是纤维素和/或蛋白质或未涂覆或涂覆的纺织材料的抗微生物膜,以及基于再生或沉淀纤维素的抗微生物海绵或抗微生物海绵布。 将薄膜,海绵或海绵布浸渍或涂覆有至少一种α-氨基酸酯,其α-氨基用脂肪酸酰化,或相应的盐酸盐,α-氨基酸酯为 与膜,海绵或海绵布共价共轭,也可以是离子键。 酰化的α-氨基酸酯优选为N-月桂酰-L-精氨酸乙酯单盐酸盐(LAECI),N-月桂酰-L-精氨酸甲酯单盐酸盐(LAMCI)或N-月桂酰-L-赖氨酸乙酯盐酸盐(LLECI) 。 该膜优选为柔性管的形式,并且被设置为用于食品的肠衣,特别是香肠产品。
