树上干杏10℃高CO2保鲜研究

摘要

Aim to realize the effects of treatments with 3%,10%,20%and 30%CO2 on the quality changes,‘Shushanggan’ apricots stored at 10℃were chosen as test material. Results showed that all these treatments had a certain effect during 30 days. Among them,treatment with 20%CO2 had a best combined evaluation. The fruit firmness,content of SSC,TA and VC and the activity of PG was 1.52 kg/cm2,19.36%,0.73%,6.88 mg/g FW,260.08μg/h·g FW,respectively. However,the difference between treatments with 10%and 20%CO 2 was not significant (P>0.05). Treatment with 30%CO2 gave apricots some harmful influence,and the quality of apricots stored in this environment was poor.%试验以新疆树上干杏为试材，研究10℃、3%O2条件下，3%、10%、20%和30%CO2处理的品质变化。结果表明：30 d内，3%、10%、20%和30%CO2处理均有一定效应，其中，20%CO2处理的综合评价最佳，贮藏期末果实硬度、SSC、TA、VC含量和PG活性分别为1.52 kg/cm2、19.36%、0.73%、6.88 mg/g FW、260.08μg/h·g FW。但是，10%CO2与20%CO2处理差异不显著（P>0.05）。30%CO2处理产生一定伤害，果实品质差。
