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.
在竹笋加工行业中，笋壳往往被丢弃而未得到任何利用。作为一种廉价的潜在膳食纤维资源，毛竹笋壳通过多种酶被分解为膳食纤维。其中，不溶性膳食纤维和可溶性膳食纤维的提取率分别为56.21%和8.67%。所得纤维表现出显著的膨胀能力、持水能力，并在体外对脂肪、胆固醇、胆汁酸和亚硝酸盐具有结合能力。给予笋壳纤维改善了高脂血症小鼠脂质代谢紊乱的状况。与正常组相比，补充总膳食纤维的小鼠体重增加最低（2.84%），总胆固醇、甘油三酯和低密度脂蛋白胆固醇分别降低31.53%、21.35%和31.53%；同时高密度脂蛋白胆固醇可增加37.6%。笋壳纤维可能成为功能性食品工业中一种潜在可用的膳食成分。
