Abstract: Special dietary fiber of moso bamboo leaves was prepared from residue extracted polysaccharides and flavones, by superfine communication technique and wetting-dynamic high-pressure microfluidization, in order to realize full and high-effective utilization of moso bamboo leave resource. Effects on water holding power, swelling, fat absorption ability, capacity of cholesterol and biliary sodium absorption and antioxidant effects on edible fat were also studied, in order to supply basis for moso bamboo leaves resources. The test results show: the water holding power and swelling increased 32% and 23% respectively; fat absorption ability for rapeseed oil and lard elevated 33.1% and 45.3%, respectively;cholesterol absorption capacities were 22.18% (pH 2)and 31.51%(pH 7), absorption capacity power was 40%(pH 7).The result also indicated that it had antioxidant effects on rapeseed oil and lard, and superior for the former.
