Abstract 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 for 20 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.
