摘　　要：竹笋是大熊猫（Ailuropoda melanoleuca）最为喜爱的天然食物。竹笋相对于竹叶和竹茎含水量更丰富,粗纤维含量更低,适口性更好;大宗养分、微量元素、必需氨基酸等含量丰富（周昂等,1996;唐平等,1997;周材权等,1997）,而丹宁等具有微毒性的次生代谢物含量却最少（赵晓红等,2001）,In order to prolong the freshness of bamboo shoots for captive giant pandas,bamboo shoots were stored at low temperatures（ 2℃- 4℃） and a high relative humidity（ 90%- 95%）,as well as treated with 20- 30 mg / m3 ozone for20 min each day. Bamboo shoots without ozone treatment served as controls. The results showed that ozone treatment significantly inhibited the reproduction of microflora（ P = 0. 001）,slowed down the rate of weight loss（ P = 0. 001）,reduced the crude fibre content（ P = 0. 001） and maintained the relative high levels of total soluble sugar content in bamboo shoots when compared with controls during storage. In addition,food preference tests showed that giant pandas prefer eating the fresh kept bamboo shoots. Therefore,the technique could be used to keep fresh bamboo shoots for captive giant pandas.
