1. A water soluble film, comprising a water soluble mixture of:
- a water soluble resin, an enzyme selected from the group consisting of cellulase and mannanase, and an enzyme substrate for said enzyme;
wherein when the enzyme is a cellulase, the enzyme substrate is selected from the group consisting of a cellulose and methyl cellulose; and
when the enzyme is a mannanase, the substrate is selected from the group consisting of a mannan and guar gum; and
wherein the enzyme substrate is not the same as the water soluble resin.

Abstract
Disclosed herein are water soluble compositions, such as films, including a mixture of a first water-soluble resin, an enzyme, and an enzyme stabilizer which comprises a functional substrate for the enzyme, methods of making such compositions, and methods of using such compositions, e.g. to make packets containing functional ingredients. The enzymes can include proteases and mixtures of proteases with other enzymes, and the compositions provide good retention of enzyme function following film processing and storage.

15. A method of forming a water soluble film, comprising providing a solution comprising a water soluble resin, an enzyme selected from the group consisting of cellulase and mannanase, and an enzyme substrate for said enzyme;
- wherein when the enzyme is a cellulase, the enzyme substrate is selected from the group consisting of a cellulose and methyl cellulose; and
when the enzyme is a mannanase, the substrate is selected from the group consisting of a mannan and guar gum;casting the solution onto a surface preheated to a temperature less than 77°
C.;drying the water from the cast solution over a period of less than 24 hours, to form a water soluble film.
- wherein when the enzyme is a cellulase, the enzyme substrate is selected from the group consisting of a cellulose and methyl cellulose; and

17. A water soluble film, the film comprising a water soluble mixture of:
-
a water soluble resin, an enzyme selected from the group consisting of cellulase and mannanase, and an enzyme substrate for said enzyme;
wherein when the enzyme is a cellulase, the enzyme substrate is selected from the group consisting of a cellulose and methyl cellulose; and
when the enzyme is a mannanase, the substrate is selected from the group consisting of a mannan and guar gum;wherein the enzyme substrate is not the same as the water soluble resin, and wherein the film exhibits an increase in enzyme recovery relative to a like film with no enzyme substrate included.
