ABSTRACT:
The present invention relates to a process for preparing collagen finings. The process comprises providing collagen in the form of undried fish isinglass which has been freshly prepared or frozen, substantially in the absence of any pre-drying, and hydrolyzing the isinglass under conditions to solubilize the collagen. By using freshly-prepared or frozen isinglass, the irreversible changes to collagen arising from pre-drying of isinglass are largely avoided.
