Isinglass

Isinglass (pronunciation: /ˈaɪsɪnɡlɑːs/) is a substance obtained from the dried swim bladders of fish. It is a form of collagen used primarily for the clarification or fining of some beer and wine. It can also be cooked into a paste for specialized gluing purposes.

Etymology

The word originates from the obsolete Dutch huizenblas - huizen is a kind of sturgeon, and blas means bladder.

Uses

Isinglass has a wide range of uses from culinary to industrial. It is used in the clarification process of wine and beer, where it helps to remove yeast and other solids. In the culinary world, it is sometimes used as a substitute for gelatin. In the past, it was used in confectionery and desserts such as marmalade and jelly.

In the industrial sector, isinglass was used for the production of certain types of adhesives, and in the 18th and 19th centuries, it was used in the bookbinding process. It was also used in the production of varnish and some paints.
