(2) adding soluble fiber to the partially hydrated rice to form a rice-fiber composition;
(3) gently mixing the rice-fiber composition to form a homogeneous mixture of the partially hydrated rice and soluble fiber;
(4) cooking the homogenous mixture to complete hydration of the rice to obtain a cooked rice composition wherein the rice is infused with the soluble fiber and wherein the cooked rice composition has a second moisture content of about 28 to about 42 percent;
(5) drying the cooked rice composition to a third moisture content of about 15 to about 23 percent to obtain a dried cooked rice composition; and
(6) treating the dried cooked rice composition by a treatment selected from the group consisting of puffing, flaking, bumping and combinations thereof to form the fiber-containing rice-based cereal which has from about 5 to about 25 percent total dietary fiber.
2. The method of claim 1 , wherein the fiber-containing rice-based cereal contains more than about 10 percent total dietary fiber.
3. The method as defined in claim 1 , wherein the dried rice has an initial total dietary fiber content of less than about 5 percent.
4. The method as defined in claim 3 , wherein the soluble fiber is selected from the group consisting of polydextrose, maltodextrins, resistant maltodextrins, inulin, guar gum, carbomethyl cellulose, high methoxy pectin, and mixtures thereof.

6. The method as defined in claim 5 , wherein dried rice is precooked in a rotatable steam cooker for about 35 to about 50 minutes at a pressure of about 9 to about 20 psi; wherein the rice-fiber composition is gently mixed in the rotatable steam cooker without steam for about 10 to 60 minutes; and wherein the homogeneous mixture is cooked in the rotatable steam cooker for about 10 to 40 minutes at a pressure of about 9 to 20 psi.
7. The method as defined in claim 4 , wherein dried rice is precooked in a rotatable steam cooker for about 35 to about 50 minutes at a pressure of about 9 to about 20 psi; wherein the rice-fiber composition is gently mixed in the rotatable steam cooker without steam for about 10 to 60 minutes; and wherein the homogeneous mixture is cooked in the rotatable steam cooker for about 10 to 40 minutes at a pressure of about 9 to 20 psi.
8. The method as defined in claim 1 , wherein the dried rice has been cleaned, milled, and polished and has an initial total dietary fiber content of less than about 1 percent.
9. The method as defined in claim 1 , wherein the soluble fiber is selected from the group consisting of polydextrose, maltodextrins, resistant maltodextrins, inulin, guar gum, carboxymethyl cellulose, high methoxy pectin, and mixtures thereof.
10. The method as defined in claim 9 , wherein dried rice is precooked in a rotatable steam cooker for about 35 to about 50 minutes at a pressure of about 9 to about 20 psi; wherein the rice-fiber composition is gently mixed in the rotatable steam cooker without steam for about 10 to 60 minutes; and wherein the homogeneous mixture is cooked in the rotatable steam cooker for about 10 to 40 minutes at a pressure of about 9 to 20 psi.
11. A method of preparing fiber-infused cooked rice, said method comprising:
(1) precooking dried rice to form a partially hydrated rice having a first moisture content of about 10 to about 20 percent;
(2) adding soluble fiber to the partially hydrated rice to form a rice-fiber composition;
(3) gently mixing the rice-fiber composition to form a homogeneous mixture of the partially hydrated rice and soluble fiber;
(4) cooking the homogenous mixture to complete hydration of the rice to obtain a cooked rice composition wherein the rice is infused with the soluble fiber and wherein the cooked rice composition has a second moisture content of about 28 to about 42 percent; and
(5) drying the cooked rice composition to a third moisture content of about 15 to about 23 percent to obtain the fiber-infused cooked rice having from about 5 to about 25 weight percent total dietary fiber and wherein the dried cooked rice is treatable by a treatment selected from the group consisting of puffing, flaking, bumping and combinations thereof to form the fiber-containing rice-based cereal.
12. The method as defined in claim 11 , wherein the dried rice has an initial total dietary fiber content of less than about 5 percent.
13. The method as defined in claim 11 , wherein the dried rice has been cleaned, milled, and polished and has an initial total dietary fiber content of less than about 1 percent.
14. The method as defined in claim 11 , wherein the soluble fiber is selected from the group consisting of polydextrose, maltodextrins, resistant maltodextrins, inulin, guar gum, carbomethyl cellulose, high methoxy pectin, and mixtures thereof.
15. The method of claim 11 , wherein the soluble fiber is polydextrose.
16. The method of claim 11 , wherein the fiber-infused cooked rice contains more than about 10 percent total dietary fiber.
17. The method as defined in claim 11 , wherein dried rice is precooked in a rotatable steam cooker for about 35 to about 50 minutes at a pressure of about 9 to about 20 psi; wherein the rice-fiber composition is gently mixed in the rotatable steam cooker without steam for about 10 to 60 minutes; and wherein the homogeneous mixture is cooked in the rotatable steam cooker for about 10 to 40 minutes at a pressure of about 9 to 20 psi.
18. The method as defined in claim 17 , wherein the dried rice has an initial total dietary fiber content of less than about 5 percent.
