Effects of Controlled Atmosphere Index on the Fruit Quality of Pyrus bretschneideri Rehd during Storage
摘要
Abstract
[Objective] The study aimed to discuss the controlled atmosphere storage condition that could keep the fruit quality of Pyrus bretschneideri rehd during storage. [Method] P. bretschneideri with consistent size and without disease-insect and machine harm were selected as the tested materials. 9 controlled atmosphere treatments with different gas composition concn. (4% O_2 + 2% CO_2, 5% O_2 + 2%CO_2, 6% O_2 + 2%CO_2, 4%O_2 + 3%CO_2, 5%O_2 + 3%CO_2, 6%O_2 +3%CO_2, 4%O_2 +4%CO_2, 5%O_2 +4%CO_2, 6% O_2 +4%CO_2) and one CK (21%O_2 + 0%CO_2) were set up to study their effects on the fruit firmness, titratable acid,respiration intensity,chlorophyll content in peel and Vc content in fruit, relative electrical conductivity in the flesh of P. bretschneideri fruit under the condition of low temperature of - 1 ℃. [Result] The suitable low-concn. of O_2 could alleviate the reduction of firmness and titratable acid, decrease the respiratory intensity of fruit, stay the degradation of chlorophyll content in peel and Vc content in fruit and restrain the rising of the relative electrical conductivity in the flesh of P. bretschneideri fruit. The appropriate storage parameters were follows; gas compositions of 5% O_2+4% CO_2 and 4% O_2 + 3% CO, storage temperature of -1 ℃ and relative humidity of 90% -95%. [Conclusion] Appropriately decreasing O_2 concn. was more favorable for keeping the fruit quality of P. bretschneideri during storage.关键词
