Abstract

The present invention provides a foam body suitable for producing a cultured meat having a good texture. The foam body of the present invention includes alginic acid and/or an alginate. The foam body has an elastic modulus M, as determined by a test, of 8×10 4 Pa or less. In the test, the foam body is immersed in 22±3° C. water for 4 hours to prepare a specimen having a post-immersion thickness of 5±1 mm. Stress and strain caused in the specimen are measured by applying a load to the specimen for 5 seconds to compress the specimen in a thickness direction at 0.5 mm/sec. A stress caused in the specimen when the specimen is compressed by 10% of an initial thickness is determined, and a value obtained by dividing the stress by a corresponding strain is determined as the elastic modulus M.

First claim

The invention claimed is:

1. A foam body comprising alginic acid and/or an alginate, and glucomannan wherein
the foam body has an elastic modulus M, as determined by a test, of 8×10 4 Pa or less,
in the test, the foam body is immersed in 22±3° C. water for 4 hours to prepare a specimen having a post-immersion thickness of 5±1 mm, stress and strain caused in the specimen are measured by applying a load to the specimen for 5 seconds to compress the specimen in a thickness direction at 0.5 mm/sec, a stress caused in the specimen when the specimen is compressed by 10% of an initial thickness is determined, and a value obtained by dividing the stress by a corresponding strain is determined as the elastic modulus M.

2. The foam body according to claim 1 being edible.

3. The foam body according to claim 1 , wherein the elastic modulus M is 1×10 3 Pa or more.

4. The foam body according to claim 1 , wherein the foam body in a dry state has an apparent density of 0.05 g/cm 3 or less.

5. The foam body according to claim 1 , comprising two or more additional polysaccharides other than the alginic acid and the alginate.

6. The foam body according to claim 1 , comprising a cellulose derivative.

7. The foam body according to claim 1 , comprising a cellulose derivative, wherein
a weight ratio between the glucomannan and the cellulose derivative in the foam body is 0.1:99.9 to 9.9:90.1.

8. The foam body according to claim 1 , comprising a compound that generates a divalent metal ion.

9. The foam body according to claim 8 , wherein the compound is calcium carbonate.

10. The foam body according to claim 8 , wherein a content of the compound in the foam body is 20 wt % or less.

11. The foam body according to claim 1 , wherein the foam body in a dry state has a pore opening at a surface.
