Abstract

1,219,463. Collagen film. JOHNSON & JOHNSON. 20 May, 1968, No. 23914/68. Heading B5B. An edible, heat sealable film at least 90% soluble in water at 70‹ C. and has a tensile strength of at least 10,000 pounds per square inch comprises collagen; the molecular weight of which has been altered by contact with a dilute acid solution of a proteolytic enzyme, and it has a free tyrosine to hydroxy-proline ratio of at least 0À062. The collagen may be obtained from the corium layer of hides. Proteolytic enzymes which may be used are bromelain, ficin, papain and proteolytic enzymes produced from genus aspergillus. Plasticers such as glycerine, sorbitol, propyleneglycol or corn syrup may be added to the modified collagen in amounts up to 50% by weight of the dry collagen solids. In addition, other film ingredients, such as, starch, vegetable gum, vegetable cooking oil, edible cellulose derivatives, gelatin, flavouring agents, colouring agents, anti-oxidants and emulsifiers may be added to the enzyme-modified collagen. Films of the enzyme-modified collagen may be prepared by grinding an aqueous slurry of collagen together with an enzyme and acidifying the mixture with an edible, non-toxic acid, such as citric acid. The acid-swollen collagen is stored for several hours at room temperature, then homogenized and de-aerated before it is extruded to form a film.
