Abstract

C3-C4 Hydroxyalkyl carboxymethyl cellulose ethers having a C3-C4 hydroxyalkyl MS of at least about 1.2 and a carboxymethyl DS of about 0.2-0.6 are superior cellulose ether foam stabilizers for carbonated malt beverages. They are compatible with chemical pasteurizing agents and can be used to improve the foam properties of beverages so treated.

Claims

2. The process of claim 1 where the hydroxyalkyl group is hydroxypropyl.

3. The process of claim 1 where the hydroxyalkyl group is 2-hydroxybutyl.

4. The process of claim 1 where the C3-C4 hydroxyalkyl MS is about 1.2-2.5.

5. The process of claim 1 were the cellulose ether has a hydroxypropyl MS of about 1.2-2.5 and a carboxymethyl DS of about 0.3-0.5.

6. The process of claim 1 where the cellulose ether has a viscosity of about 20-8,000 cps as a 2 percent aqueous solution at pH 7.0 and 20* C.

7. The process of claim 1 where about 10-200 ppm of the C3-C4 hydroxyalkyl carboxymethyl cellulose ether is added.

8. The process of claim 1 where the beverage contains a chemical pasteurizing agent.

9. The process of claim 8 where the pasteurizing agent is an alkyl p-hydroxybenzoate.

10. The process of claim 9 where the pasteurizing agent is n-heptyl p-hydroxybenzoate.

11. A fermented malt beverage having improved foam properties from the addition of a water-soluble C3-C4 hydroxyalkyl carboxymethyl cellulose ether having a C3-C4 hydroxyalkyl MS of at least about 1.2 and a carboxymethyl DS of about 0.2-0.6.

12. The beverage of claim 11 containing as a foam stabilizer about 10-200 ppm of hydroxypropyl carboxymethyl cellulose ether having a hydroxypropyl MS of about 1.2-2.5 and a carboxymethyl DS of about 0.3-0.5.

13. A finished beer having improved microbiological stability and foam properties from the addition of a chemical pasteurizing agent and a C3-C4 hydroxyalkyl carboxymethyl cellulose ether having a C3-C4 hydroxyalkyl Ms of at least about 1.2 and a carboxymethyl DS of about 0.2-0.6.

14. The beer of claim 13 containing a microbiological growth inhibiting amount of n-heptyl p-hydroxybenzoate and about 10-200 ppm of a hydroxypropyl carboxymethyl cellulose ether having a hydroxypropyl MS of about 1.2-2.5 and a carboxymethyl DS of about 0.3-0.5.
