The invention relates to a paper product having 0.1 to 10 percent of an acid treated seed based fiber material incorporated into the paper making composition. The remainder of the paper product can be pulp fibers, for example wood fibers. The seed based fiber material is present on the surface of the pulp fibers and imparts certain properties to the paper product formed from it.

What is claimed is: 1. A paper product comprising: a fiber used in producing a paper product; and an acid treated seed based fiber material, the acid treated seed based fiber material having: a reduced lignin content when compared to unmodified seed based fiber; a total cellulose character of at least 50%; and a total hemicellulose character of at least 5%; wherein the acid treated seed based fiber material provides the paper product with an increased content of microfibrils and a reduced void content compared to paper products without the acid treated seed based fiber material. 2. The paper product according to claim 1, wherein the acid treated seed based fiber material has a ratio of cellulose character to hemicellulose character of at least 2:1. 3. The paper product according to claim 1, wherein the acid treated seed based fiber material comprises acid treated corn fiber having a total cellulose character of at least 60%. 4. The paper product according to claim 3, wherein the acid treated corn fiber has a ratio of cellulose character to hemicellulose character of at least 5:1. 5. The paper product according to claim 1, wherein the acid treated seed based fiber material comprises acid treated soy fiber having a total cellulose character of at least 50%. 6. The paper product according to claim 5, wherein the acid treated soy fiber material has a ratio of cellulose character to hemicellulose character of at least 2:1. 7. The paper product according to claim 1, wherein the acid treated seed based fiber material comprises acid treated oat fiber having a total cellulose character of at least 60%. 8. The paper product according to claim 7, wherein the acid treated oat fiber has a ratio of cellulose character to hemicellulose character of at least 4:1. 9. The paper product according to claim 1, wherein the acid treated seed based fiber material comprises acid treated corn fiber, acid treated oat fiber, acid treated soy fiber, or mixtures thereof. 10. The paper product according to claim 1, wherein the acid treated seed based fiber material is produced by a process comprising treating a seed based fiber with an acid solution comprising about 0.001% to about 5% acid, based on the dry weight of the unmodified seed based fiber. 11. The paper product according to claim 10, wherein the resultant acid treated seed based fiber is further treated with a peroxide. 12. The paper product according to claim 1, wherein the acid treated seed based fiber material is present in an amount ranging from about 0.1% to about 10% based upon the amount of the fiber used in producing the paper product. 13. The paper product according to claim 12, wherein the fiber used in producing the paper product is pulp fiber. 14. The paper product according to claim 13, wherein the pulp fiber is selected from the group consisting of a wood fiber, a non-wood fiber, an animal fiber, a mineral fiber, a synthetic fiber, and mixtures thereof. 15. The paper product according to claim 14, wherein the pulp fiber is a wood fiber. 16. The paper product according to claim 1, wherein the fibers used in producing the paper product have the acid treated seed based fiber material disposed thereon. 17. The paper product according to claim 1, further comprising a cationic starch. 18. The paper product according to claim 1, wherein the paper product is selected from the group consisting of newsprint, bond paper, fine paper, paperboard, tissue, linerboard, corrugating medium, and kraft bags. 19. The paper product according to claim 1 wherein the increased content of microfibrils is at least about 10% compared to paper products without the modified seed based fiber material. 20. The paper product according to claim 1 wherein the acid treated seed based fiber material comprises a powder having material sized no greater than approximately 250 microns. 21. A paper product comprising a) paper fibers; and b) an acid treated seed based fiber material, the acid treated seed based fiber having a total cellulose character of at least 50%, a total hemicellulose character of at least 5%, and a reduced lignin content compared to the seed based fiber before acid treatment; and wherein the paper product has increased paper strength when compared to a paper product of the same basis weight that has the paper fibers without the acid treated seed based fiber material. 22. The paper product according to claim 21 wherein the paper product has an increased content of microfibrils and a reduced void content compared to paper products without the acid treated seed based fiber material. 23. The paper product according to claim 22 wherein the increased content of microfibrils is at least about 10% compared to paper products without the acid treated seed based fiber material.
