title: Hydration properties and binding capacities of dietary fibers from bamboo shoot shell and its hypolipidemic effects in mice.
abstract: In the bamboo shoot processing industries, bamboo shoot shells are discarded without any utilization. As a cheap potential dietary fibers resource, bamboo shoot (Leleba oldhami Nakal) shell was decomposed to dietary fibers by multiple enzymes. The extraction yields of insoluble dietary fiber and soluble dietary fiber were 56.21% and 8.67%, respectively. The resulting fibers showed significant swelling capacity, water holding capacity and exhibit in vitro binding capacities to fat, cholesterol, bile acids and nitrites. The administration of bamboo shoot shell fibers improved the lipid metabolism disorderly situation of hyperlipidemia mice. Compared with normal group, total dietary fiber supplement could exhibit the lowest body weight gain (2.84%) in mice, and decrease total cholesterol, triglyceride and low density lipoprotein-cholesterol by 31.53%, 21.35% and 31.53%, respectively; while it can increase high density lipoprotein-cholesterol by 37.6%. The bamboo shoot shell fibers could be a potentially available dietary ingredient in functional food industries.
