摘　　要：为了适应梨果实互联网销售的新模式,以丰水梨果实为试验材料,研究了乙烯和CO_2气体吸收剂对小包装丰水梨果实货架期品质的影响。结果显示,与带孔包装(CK)和PE密封包装(PE)相比,添加10 g乙烯吸收剂(PE+EA)和10 g乙烯吸收剂+3 g CO_2吸收剂(PE+EA+CA)处理显著减缓了果实硬度、TSS含量的下降,降低了果实丙二醛含量,并抑制了果心组织的褐变,从而保持了果实较好的滋味特性,其中PE+EA+CA处理的效果更佳,这可能与其降低果实的呼吸速率有关。说明,10 g乙烯吸收剂+3 g CO_2吸收剂处理可作为一种保持小包装丰水梨果实流通及货架期较好品质的有效方法。To suit the new sales pattern of pear on internet,the effects of gas absorbing agent of ethylene and CO2 on the shelf quality of little packaged Hosui pear were investigated. The results showed that the treatments of ethylene absorbent（ PE＋EA） and combination with CO2absorbent（ PE ＋EA ＋CA） significantly alleviated the decrease of firmness and total soluable solid（ TSS） content,reduced the increase of malonaldehyde,and inhibited the browning of fruit core compared with the control and PE packaged treatment,so the characteristic of taste was maintained. The effect of PE＋EA＋CA treatment was better,which might be due to the inhibition of respiratory rate. The treatment of the combination of gas absorbing agent of ethylene and CO2 can be used as an effective method of keeping the circulating and shelf quality of little packaged Hosui pear.
