1. A method of making paper comprising incorporating at least about 0.1% to 10% by weight of acid treated seed based fiber in a papermaking slurry based on the weight of fiber in the pulp mixture, said acid treated seed based fiber having a total cellulose character of at least 50% and a total hemicelluloses character of at least 5%, wherein said acid treated seed based fiber material has been treated at a pH less than 2.5 at a temperature between 110° C. and 140° C. for approximately 30 minutes to approximately 60 minutes; whereby said paper has an increased burst index and/or tensile strength in the machine and/or cross direction relative to paper that is prepared by a process that is otherwise the same but lacking the addition of said seed based fiber.
