The invention discloses a method for preparing dietary fibers from
salicornia stalks by a biological method. The dietary fibers are creamy white in color, the functional indexes of the dietary fibers are far higher than a
dietary fiber standard frequently used by western countries, and the dietary fibers can be used as high-quality dietary fibers and an ideal
food additive. The method disclosed by the invention has the advantages that a united technology of micro
fermentation,
microwave-assisted enzymolysis and multi-strain sectional type
fermentation is adopted for extracting dietary fibers from the
salicornia stalks, so that the yield of the dietary fibers from the
salicornia stalks is increased; a technology of
microwave-assisted enzymolysis,
microorganism sectional type
fermentation and enzymolysis modification is adopted, so that the
nutrient value of salicornia dietary fibers is notably promoted, and the dietary fibers are good in
palatability; and the production cost of the technology is low, industrialized production is facilitated, a way of developing and utilizing the dietary fibers from the salicornia stalks, which is high in efficiency, low in cost, safe and feasible, is established, in the respect of the cost of the dietary fibers, the
economic benefits of the dietary fibers are increased by 30% or above than those of dietary fibers of the same kind, and a new way is provided for further
resource utilization of the salicornia stalks.
