    • This invention relates to a novel use of cationic preservatives and preparations according to this novel use. A cationic preservative derived from lauric acid and arginine, in particular, the ethyl ester of the lauramide of the arginine monohydrochloride, hereafter named LAE, can be used for the protection against the growth of microorganisms. The chemical structure of LAE is described in formula (I). LAE and related compounds are particularly suitable to be used in the preservation of all perishable food products. It is preferred to dissolve the compound directly before use in one of the following preferred solvents of food grade: water, ethanol, propylene glycol, isopropyl alcohol, other glycols, mixtures of glycols and mixtures of glycols and water. If the treatment shall be performed at a specific pH value the use of a corresponding buffer solution may be recommendable. The composition optionally comprises auxiliary components and excipients. Such auxiliary components and excipients can be thickening agents (e.g. xanthan gum, guar gum, modified starches), anti-foam agents (e.g. dimethylpolysiloxane, silicon dioxide), products to obtain the optimal pH value (e.g. phosphates, tartrates, citrates, lactates), colouring agents (e.g. curcumin, tartrazine, erythrosine), and aroma products. It is preferred, that the preservative composition comprises LAE in an amount of from 0.0001% to 1% by weight relative to the whole weight of the preservative composition. It is particularly preferred to use the inventive composition for the preservation of meat products, like for instance meat, poultry products, fish, crustaceans, vegetables, greens, emulsions, sauces, confectionery, bakery, pre-cooked meals, ready-to-serve meals, dairy products, egg-based products, jams, jellies, beverages, juices, wines and beers.
    • 本发明涉及根据该新用途的阳离子防腐剂和制剂的新用途。 衍生自月桂酸和精氨酸的阳离子防腐剂,特别是精氨酸一盐酸盐的月桂酰胺的乙酯(以下称为LAE)可用于防止微生物的生长。 LAE的化学结构在式(I)中描述。 LAE和相关化合物特别适用于保存所有易腐食品。 优选在直接使用前将化合物溶解在食品级的以下优选溶剂之一:水,乙醇,丙二醇,异丙醇,其它二醇,二醇的混合物,以及二醇和水的混合物。 如果处理应在特定的pH值下进行,则可能推荐使用相应的缓冲溶液。 组合物任选地包含辅助成分和赋形剂。 这样的辅助成分和赋形剂可以是增稠剂(例如黄原胶,瓜尔胶,改性淀粉),消泡剂(例如二甲基聚硅氧烷,二氧化硅),获得最佳pH值的产物(例如磷酸盐,酒石酸盐,柠檬酸盐,乳酸盐) ,着色剂(如姜黄素,酒石黄,赤藓红)和芳香产品。 优选的是,防腐剂组合物相对于防腐剂组合物的总重量包含0.0001%至1%重量的LAE。 特别优选使用本发明的组合物来保存肉制品,例如肉类,家禽产品,鱼类,甲壳类,蔬菜,蔬菜,蔬菜,乳汁,调味汁,糖果,面包店,预先烹制的食物,即食服务 膳食,乳制品,蛋制品,果酱,果冻,饮料,果汁,葡萄酒和啤酒。

    • A virgin chitosan polymer is added to an acid and water solution in an amount sufficient to form an edible composition having a solids content greater than five percent (5%) and a liquid viscosity. The composition is applied to food products, such as fruits, vegetables and nuts, to provide an edible protective coating for the food products. Alternatively, chitosan may be hydrolyzed to a lower molecular weight so that a gel will not be formed when the partially hydrolyzed chitosan is admixed to the acid water solution. An edible wax emulsion and/or a preservative such as sodium benzoate, and/or an adhesion additive such as zinc acetate, and/or a wetting agent, and/or one or more additives from the group consisting of virgin and/or modified carbohydrates, proteins, hydrocolloides, lipids, oils, gums and waxes, natural and/or synthetic, made be added to the composition before it is applied to the food product. In a preferred form, a chitosan polymer is used that has a molecular weight sufficient to form a composition having a solids content of about fifteen percent (15%) or higher.
    • 将原始壳聚糖聚合物以足以形成固体含量大于5%(5%)和液体粘度的可食用组合物的量加入到酸和水溶液中。 该组合物适用于食品,如水果,蔬菜和坚果,为食品提供食用保护涂层。 或者,壳聚糖可以被水解成较低分子量,使得当部分水解的壳聚糖与酸性水溶液混合时,不会形成凝胶。 可食用蜡乳液和/或防腐剂如苯甲酸钠和/或粘合添加剂如乙酸锌和/或润湿剂,和/或一种或多种来自由原始和/或修饰的碳水化合物组成的组的添加剂 将天然和/或合成的蛋白质,水解胶体,脂质,油,树胶和蜡在施用于食品之前加入到组合物中。 在优选形式中,使用具有足以形成固体含量为约15%(15%)或更高的组合物的分子量的壳聚糖聚合物。
