    • A polymer-based sausage casing suitable for use with uncooked meats such as chorizo is disclosed. A polymer resin is blended with a silicon-based barrier control agent, preferably a polyhedral oligomeric silsesquioxane, to increase the permeability of the sausage casing. The resultant blend can be biaxially stretch-oriented to produce a single-layered polymer-based sausage casing suitable for use with uncooked sausage meats such as chorizo, and specifically suitable for the gas and moisture permeability needed during the curing process for uncooked sausage meats. Such polymer-based casings can also be employed for cooked sausages by choosing a silicon-based barrier control agent that increases gas and moisture barrier, thereby increasing shelf-life for unpeeled sausages. A method for improving the peelability of cooked sausage casings by injecting a thin coating of a releasing agent, without the addition of a surfactant, into the sausage casing during the shirring process is also disclosed. The releasing agent is a hydroxypropyl methylcellulose solution that creates a low viscosity releasing agent that effectively improves peelability from any type of sausage casing, but preferably for use with the polymer-based sausage casing of the present invention.
    • 公开了一种适合与未煮过的肉类如香肠一起使用的基于聚合物的香肠肠衣。 将聚合物树脂与硅类屏障控制剂(优选多面体低聚倍半硅氧烷)共混以增加香肠肠衣的渗透性。 所得共混物可以双轴拉伸取向以制备适用于未煮过的香肠肉如香肠的单层聚合物型肠衣,并且特别适用于未煮熟的香肠肉的固化过程中所需的气体和水分渗透性。 这种基于聚合物的肠衣也可以通过选择增加气体和水分屏障的硅基屏障控制剂,从而增加未剥皮香肠的保存期限而被用于熟香肠。 还公开了一种通过在收缩过程中将没有添加表面活性剂的薄涂层的脱模剂注射到香肠套管中来改善煮熟的香肠肠衣的可剥离性的方法。 脱模剂是产生低粘度脱模剂的羟丙基甲基纤维素溶液,其有效地改善了任何类型的香肠肠衣的剥离性,但优选用于本发明的基于聚合物的香肠肠衣。
