不同气体成分对意大利葡萄贮藏中乙醇、乙醛含量的影响

Effect of Different Atmo spheres on the Contents of Alcohol and Aldehyde in the Berries of Italia Grape Variety During Storage

研究了9种气体组分对意大利葡萄中乙醇、乙醛含量的影响,初步确定了5%O2+3%CO2气调指标下意大利葡萄中乙醇、乙醛含量处于最低和较低水平;5%CO2+3%O2气调指标下,浆果中乙醛含量最高;8%CO2+5%O2气调指标下,浆果中乙醇含量最高。当CO2浓度低于5%时,CO2浓度对浆果中乙醇、乙醛含量均无影响;O2浓度、O2浓度与CO2浓度交互作用对浆果中乙醇含量有显著影响;O2浓度对浆果中乙醛含量有一定影响;O2浓度与CO2浓度交互作用对浆果中乙醛含量有显著影响。

The contents of alcohol and aldehyde in the berries of grape variety Italia were analyzed under9different kinds of atmospheric conditions.Results showed the contents of alcohol and aldehyde were the lowest under the condition of5%O 2 +3%CO 2 .On the contrary,the content of aldehyde was the highest under the condition of5%CO 2 +3%O 2 ,and it was the same with the content of alcohol under the condition of8%CO 2 +5%O 2 .When the concentration of CO 2 was below5%,it didnt affect the contents of alcohol and aldehyde,but the concentration of O 2 and the concentration of O 2 and CO 2 affected the content of al-cohol very much.At the same time the concentration of O 2 affected the content of aldehyde a little,and the concentration of O 2 and CO 2 affected the content of aldehyde.
