    Abstract: The invention relates to a process for preparing beadlets containing fat soluble substances in a gelatin matrix which comprises crosslinking the gelatin by radiation or enzymatically. Specifically, the invention relates to a process for preparing beadlets containing fat soluble substances having the steps of: (1) forming an aqueous emulsion of a fat soluble substance, a gelatin, a reducing agent; (2) converting the emulsion into a dry powder; and (3) crosslinking the gelatin matrix in the coated particles by exposing the coated particles to radiation or, in the case of a crosslinking enzyme being present, by incubating the coated particles.

    Abstract: A transparent native, non-fibrilized collagen material is described having an absorbence at a wavelength of 900 nm of less than 5% in a sample 5 mm thick. This collagen material is useful for a prosthetic replacement of the cornea because of the high transparency and because it is a native material, and thus less susceptible to immunogenic responses. A method for forming the native, non-fibrilized, highly transparent collagen material comprises ultracentrifuging a purified solution of native collagen to form a pellet of transparent collagen material, and fixing the pellet of collagen material to form a rigid, leather-like material. The collagen material can also be used for prosthetic replacement of other bodily tissues, such as nucleus pulposus, cartilage, and vitreous body.

    Abstract: Proteinaceous material such as gelatin is hardened by treatment with an aqueous solution of the partial hydrolysis product of a 2,4-dichloro-6-alkoxy-S-triazine with a water-soluble tertiary phosphate and/or a water-soluble borate, wherein the 2,4-dichloro-6-alkoxy-s-triazine corresponds to the formula: ##STR1## wherein R is a lower alkyl or alkoxyalkyl group. The proteinaceous material can be a proteinaceous coating such as a photographic silver halide emulsion layer, a backing layer, a protective layer, a filter layer, or any other photographic auxiliary layer.

    Abstract: Aldehyde cross-link intermediates and cross-links are generated in the central helical portion of collagen by incubating collagen with pyridoxal-5-phosphate and either cupric copper ion or ferrous iron ion. The cross-links are chemically similar to natural cross-links found in the non-helical regions and are directly between amino-acid moieties naturally occuring in the central helical portion of collagen. Cross-linking and utilization of aldehyde intermediates occurs when the product is reincubated after pyridoxal is removed. Alternatively maintaining the product at body temperatures will promote cross-linking. The cross-linked collagen product has increased resistance to enzyme degradation.
