Abstract
A preparation is disclosed herein which may be used for making shaped articles, particularly for making tubular films for the packaging of sausages. The preparation comprises collagen and a precondensate, which precondensate comprises A. one or more structural units derivable from a compound containing at least one amine group, and B. one or more structural units derivable from a compound containing at least one aldehyde group and/or one or more structural units derivable from a polyhydroxy compound. Also disclosed are a process for making the preparation, a method of making a shaped article from the preparation, and shaped articles so made. The collagen used is advantageously contained in an animal hide fibre composition.
Claims45
A preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amino group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group, or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing at least 39% but at most 90% by weight of precondensate, based on the weight of collagen plus precondensate.
A preparation which comprises collagen and at least 39% of a precondensate of casein, formaldehyde and, optionally, glycerol based on the weight of collagen plus precondensate.
A moulding preparation for the manufacture of films, especially tubular films for packaging sausages, which preparation comprises
- a. animal hide fibre composition, and
- b. at least 39% of an aminoplast precondensate of one or more compounds containing free amino groups with one or more aldehydes and, optionally, one or more polyhydroxy compounds based on the weight of the fiber composition plus precondensate.
A process for the manufacture of a preparation suitable for making a shaped article, which comprises mixing collagen with at least 39% of a precondensate based on the weight of a collagen plus precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amine group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group and/or one or more structural units derivable from a polyhydroxy compound.
A method of manufacturing a shaped article which comprises shaping a preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amine group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group, or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing at least 39% but at most 90% by weight of precondensate, based on the weight of collagen plus precondensate to the desired shape and drying, and if necessary heating the preparation to cause the collagen to crosslink and the precondensate to crosslink.
A sausage wherein the casing is derived from a preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amine group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group, or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing at least 39% but at most 90% by weight of precondensate, based on the weight of collagen plus precondensate.
A preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amino group, and or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing from about 50% to at most 90% by weight of precondensate, based on the weight of collagen plus precondensate.
A method of manufacturing a shaped article which comprises shaping a preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amine group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group, or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing from about 50% to at most 90% by weight of precondensate, based on the weight of collagen plus precondensate to the desired shape and drying, and if necessary heating the preparation to cause the collagen to crosslink and the precondensate to crosslink.
A sausage wherein the casing is derived from a preparation which comprises collagen and a precondensate, which precondensate comprises
- a. one or more structural units derivable from a compound containing at least one amine group, and
- b. one or more structural units derivable from a compound containing at least one aldehyde group, or one or more structural units derivable from a polyhydroxy compound which precondensate is also reacted with a compound containing an aldehyde group, said preparation containing from about 50% to at most 90% by weight of precondensate, based on the weight of the collagen plus precondensate.
