Abstract

An edible pet chew is disclosed that is comprised of fibrous protein, water absorbing polymer, plasticizer, water, and a combination of anthocyanins and turmeric. The pet chew provides excellent textural properties and improved solubility in the stomach and intestinal environment for improved pet safety.

First claim

1 . An edible pet chew comprising:
a. fibrous protein in an amount of from about-15 to about 90% by weight of the chew; b. water absorbing polymer in an amount of from about 5 to about 35% by weight of the chew, wherein the water absorbing polymer is selected from gelling proteins, hydrocolloids, edible hydrogels, and mixtures thereof; c. plasticizer in an amount of from about 5 to about 40% by weight of the chew; d. water in an amount of from about 1 to about 20% by weight of the chew; and e. a combination of anthocyanins and turmeric, wherein the combination of anthocyanins and turmeric provides a green color to the chew.

2 . The edible pet chew of claim 1 , wherein at least one of the anthocyanins is derived from at least one member of the group consisting of Vaccinium species, such as blueberry, cranberry, and bilberry; Rubus berries, including black raspberry, red raspberry, and blackberry; blackcurrant; cherry; eggplant peel; black rice; Concord grape; muscadine grape; red cabbage; violet petals; black soybean; skins of black chokeberry; Amazonian palm berry; blood orange; marion blackberry; cherry; redcurrant; purple corn; and acai.

3 . The edible pet chew of claim 2 , wherein the anthocyanins have a pH that allows the anthocyanins to appear blue.

4 . The edible pet chew of claim 2 , wherein a source of the anthocyanins comprises red cabbage.

5 . The edible pet chew of claim 4 , wherein the source of anthocyanins has a pH of from 8 to 9.

6 . The edible pet chew of claim 1 , wherein the turmeric has a pH allowing the turmeric to appear yellow.

7 . The edible pet chew of claim 6 , wherein the turmeric has a pH of from 4.5 to 6.5.

8 . The edible pet chew of claim 1 , further including a pH stabilizer adapted to stabilize the pH of the pet chew such that the anthocyanins provide a blue color, which contributes to the green color of the pet chew.

9 . The edible pet chew of claim 8 , wherein the pH stabilizer further comprises an enzyme.

10 . The edible pet chew of claim 1 , wherein the combined amount of the anthocyanins and turmeric comprises from about 0.005% to 5.0% by weight of the chew.

11 .- 15 . (canceled)

16 . The edible pet chew of claim 1 , wherein the green color produced by the combination of anthocyanins and turmeric has a Pantone reference range of from about P 163-14 U to about P 165-16 U.

17 . The edible pet chew of claim 1 , wherein the green color produced by the combination of anthocyanins and turmeric has a wavelength of from 490 nm to 560 nm.

18 . (canceled)

19 . The edible pet chew of claim 1 , wherein the solubility of the pet chew is at least 60% in vitro disappearance (IVD).

20 . (canceled)

21 . The edible pet chew of claim 1 , further comprising starch in an amount less than about 5% by weight of the chew.

22 .- 39 . (canceled)

40 . A method of preparing an edible pet chew comprising the steps of:
a. forming a pet chew composition by admixing
fibrous protein in an amount of 15% to 90% by weight of the composition,
water absorbing polymer in an amount of 5% to about 35% by weight of the chew, wherein the water absorbing polymer is selected from gelling proteins, hydrocolloids, edible hydrogels, and mixtures thereof;
plasticizer in an amount of 5% to 40% by weight of the composition;
water in an amount of 1% to 20% by weight of the composition; and
a combination of anthocyanins and turmeric in an amount to produce a green color;
b. thermoplasticizing the pet chew composition; and c. molding the thermoplastic pet chew composition to form the edible pet chew.

41 . The method of claim 40 , wherein the anthocyanins and turmeric are mixed with the water prior to combination of any liquid ingredients with any dry ingredients.

42 . The method of claim 41 , wherein the turmeric and anthocyanins are metered in a mixture of glycerin and water and then added to the dry ingredients.

43 .- 44 . (canceled)

45 . The method of claim 40 , wherein the anthocyanins are derived from at least one of a blueberry, a cranberry, a bilberry, a black raspberry, a red raspberry, a blackberry, a blackcurrant, a cherry, an eggplant peel, black rice, a Concord grape, a muscadine grape, red cabbage, a violet petal, a black soybean, a black chokeberry, an Amazonian palm berry, a blood orange, a marion blackberry, a cherry, a redcurrant, a purple corn, or an acai.

46 . The method of claim 40 , wherein the turmeric is provided in powder form.
