Provided is a fermented food containing an extract of at least one plant material selected from the group consisting of turmeric, Houttuynia cordata Thunb., Eucommia ulmoides Oliv., rice bran, persimmon leaves, perilla, clove, cinnamon and Rubus suavissimus S. Lee (Rosaceae) and bacteria of the genus Bifidobacterium. The fermented food contains an excellent and novel material with which the viability of the bacteria of the genus Bifidobacterium can be improved in storage of the product, and even when used in products such as beverages or foods, does not deteriorate the flavor of the product, thereby the bacteria of the genus Bifidobacterium can be contained at high concentration which provides various physiological effects.

1. A method for producing a fermented food containing live bifidobacteria comprising: including in a fermented food that contains live bifidobacteria an acid extraction extract of Rubus suavissimus S. Lee (Rosaceae);wherein said acid extraction extract is prepared by extracting said Rabus suavissimu
1. A method for producing a fermented food containing live bifidobacteria comprising: including in a fermented food that contains live bifidobacteria an acid extraction extract of Rubus suavissimus S. Lee (Rosaceae);wherein said acid extraction extract is prepared by extracting said Rabus suavissimus S. Lee (Rosaceae) in an aqueous acid solution at pH 4.0 or less;wherein said acid extraction extract is included in an amount ranging from 0.001% 1.0% by weight as calculated in terms of an extract adjusted to 10 degrees Brix (sugar content);wherein said extract is included in an amount sufficient to increase the viability of the bifidobacteria in the fermented food after storage at 10° C. for 14 days compared to the viability of bifidobacteria in an otherwise identical fermented food which does not contain the extract; andwherein said bifidobacteria are selected from the group consisting of Bifidobacterium breve and Bifidobacterium bifidum; or both. 2. The method of claim 1, wherein said live bifidobacteria are Bifidobacterium breve. 3. The method of claim 1, wherein said fermented food contains 1×107/mL or more live bifidobacteria. 4. The method of claim 1, wherein said fermented food contains 1×108/mL or more live bifidobacteria. 5. The method of claim 1, wherein the fermented food is a fermented milk or dairy product. 6. The method of claim 5, wherein the fermented milk or dairy product is selected from the group consisting of a fermented milk, hard yogurt, soft yogurt, and plain yogurt. 7. The method of claim 5, wherein the fermented food is kefir or cheese. 8. The method of claim 1, wherein said acid extraction extract is an extract of Rubus suavissimus S. Lee (Rosaceae) leaves prepared by extraction in an aqueous solution of citric acid. 9. The method of claim 8, wherein the fermented food is a fermented milk or dairy product. 10. The method of claim 8, wherein the acid extraction extract is added to a fermented milk or fermented dairy product selected from the group consisting of a fermented milk, hard yogurt, soft yogurt, plain yogurt, kefir and cheese. 11. A fermented food produced by the method of claim 1. 12. A fermented food produced by the method of claim 2. 13. A fermented food produced by the method of claim 3. 14. A fermented food produced by the method of claim 4. 15. A fermented food produced by the method of claim 5. 16. A fermented food produced by the method of claim 6. 17. A fermented food produced by the method of claim 7. 18. A fermented food produced by the method of claim 8. 19. A fermented food produced by the method of claim 9. 20. A fermented food produced by the method of claim 10. 21. A fermented milk food containing live bifidobacteria comprising an acid extraction extract of at least one plant material selected from the group consisting of turmeric (rootstock of Curcuma longa L.), Houttuynia cordata Thunb., Eucommia ulmoides Oliv., rice bran, persimmon leaves, clove, cinnamon, and Rubus suavissimus S. Lee (Rosaceae); wherein said acid extraction extract is prepared by extracting said at least one plant material in an aqueous acid solution at pH 4.0 or less;wherein said acid extraction extract is included in an amount ranging from 0.001% 10.0% by weight of the fermented milk food as calculated in terms of an extract adjusted to 10 degrees Brix (sugar content); andwherein said extract is included in an amount sufficient to increase the viability of the bifidobacteria in the fermented milk food after storage at 10° C. for 14 days compared to the viability of bifidobacteria in an otherwise identical fermented milk food which does not contain the extract. 22. A fermented food produced by the method of claim 21.
