Study on functional properties of powder from aging bamboo shoots and its utilization for cookies

Adsorption capacity of cholesterol, sodium cholate and heavy metal ions in vitro of bamboo powder from aging parts of harvested bamboo shoots ( Dendrocalamopsis oldhami) , influence of added the bamboo powder on pasting properties of wheat starch, and the best formulation of bamboo cookies were investigated in this paper.The result showed that the adsorption of cholesterol were 17.11 mg / g and 1.02 mg / g under p H2 and p H7, and the adsorption quantity were 64.7mg / g and 75 mg / g respectively, when the cholic acid sodium concentration were 2and 3mg / m L.The adsorption capacity for four heavy metals decreased in the following order: Pb2 +> Cd2 +> Cu2 +> Zn2 +.Peak viscosity, trough viscosity, final viscosity, setback and peak time changed obviously with increasing addition of bamboo powder, but there were no significant influence on breakdown and pasting temperature.Also, the bamboo cookies processing conditions were determined based on single factor test and L9 ( 34) orthogonal experiments for sensory evaluation, and the best formulation was as following: wheat starch∶bamboo powder∶sugar∶sweller∶vegetable oil = 100∶15∶25∶1.5∶15, and the score was 51.4.
