2 . The method according to claim 1 , wherein the saccharide is comprised of one or more saccharides which is composed of a monosaccharide having 3 to 7 carbon atoms.

3 . The method according to claim 1 , wherein the saccharide solution is derived from inedible raw materials.

4 . The method according to claim 1 , wherein the hydrogenation reaction is carried out in the presence of a metal catalyst.

5 . The method according to claim 1 , wherein the carbonyl compound other than the saccharide is at least one selected from an aldehyde compound and a ketone compound.

6 . The method according to claim 1 , wherein the unsaturated alcohol is an aliphatic conjugated alcohol.

7 . A hydrogenated saccharide solution obtained by the method according to claim 1 .

8 . The hydrogenated saccharide solution according to claim 7 , wherein furfural content in the hydrogenated saccharide solution is 0.01% by mass or less of the total amount of the hydrogenated saccharide solution.

9 . The hydrogenated saccharide solution according to claim 7 , wherein glycolaldehyde content in the hydrogenated saccharide solution is 0.03% by mass or less of the total amount of the hydrogenated saccharide solution.

10 . A method for producing an organic compound, the method comprising:
hydrogenating a saccharide solution which is comprised of saccharide and at least one selected from the group consisting of a carbonyl compound and an unsaturated alcohol, wherein the carbonyl compound is other than a saccharide, and producing an organic material in which a microorganism capable of producing an organic material is acted in an aqueous medium on an organic raw material containing the saccharide solution after the step of hydrogenating.

11 . A method for producing an organic compound, the method comprising producing an organic material in which a microorganism capable of producing an organic material is acted in an aqueous medium on an organic raw material containing the hydrogenated saccharide solution according to claim 7 .

12 . The method for producing an organic compound according to claim 10 , wherein the step of producing an organic material is carried out under an anaerobic atmosphere.

13 . The method for producing an organic compound according to claim 10 , further comprising purifying the organic compound obtained in the step of producing the organic material.

14 . The method for producing an organic compound according to claim 10 , wherein the aqueous medium is comprised of at least one selected from a carbonate ion, a bicarbonate ion, and a carbon dioxide gas.
