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.
Claims28
A process for preparing collagen finings comprising the steps of providing collagen in the form of fresh undried fish isinglass, freezing the isinglass in the absence of any pre-drying, and hydrolyzing the isinglass under conditions to solubilize the collagen.
A process for preparing collagen finings comprising the steps of providing collagen in the form of undried fish isinglass which has been freshly prepared in the absence of any pre-drying, and hydrolyzing the isinglass under conditions to solubilize the collagen.
A process for clarifying fermented beverages comprising the steps of adding collagen finings to the beverage wherein the collagen finings are made from fish isinglass prepared without pre-drying the isinglass, said fish isinglass being hydrolyzed under conditions to solubilize collagen in the isinglass to provide the collagen finings;
- and precipitating suspended material in the beverage to clarify the beverage.
A process for preparing and handling fish isinglass for use in preparation of collagen finings for clarifying potable liquors comprising separating swim bladders from fish;
- rapidly freezing the freshly separated swim bladders in the absence of predrying;
- and transporting the swim bladders in a frozen condition.
