Spatial distribution of gas concentrations and RQ in a controlled atmosphere storage container with pear fruit in very low oxygen conditions.
Controlled atmosphere storage can lengthen the storage life of some apple and pear varieties by several months. Controlled atmospheres (CA) slows ripening and maintains firmness, but also inhibits some flavor development. Sweetness and tartness are preserved to some extent by the use of CA, but other flavors may be lessened in CA-stored fruit.
Pear fruit is popular among the consumers due to its sweetness, crispness, characteristic fragrance and slight aroma (Chen et al. 2007). The “Qiushui” pear fruit have a typical climacteric ripening behavior, relatively thicker peel and storage tolerance. However, the fruit quality changes sharply in relation to its storage environment.
Efficacy of treatments of partially ripe fruit firmness will be conducted after various storage durations in RA and CA. Physiological indicators of fruit development (respiration, ethylene production and ethylene sensitivity) will be evaluated as predictors of ripening potential and MCP response.

CA storage monitors constantly by adjusting O2 and CO2 level within gas tight stores or containers. Practical advantages of storage under Controlled Atmosphere: 1. Considerable decrease in fruit respiration rate. 2. A reduction in the effect of ethylene on metabolism. 3. An extension in storage life and excellent firmness of flesh.

For pears, the recommended atmosphere for CA storage contains 2.0 to.
The Physiological Disorders section of the card set includes most the common disorders of physiological origins found during the sorting and packing. level is too high during controlled atmosphere (CA) storage both external and internal injury symptoms may. Excess or too low humidity can have a detrimental effect on fruit during storage.
Storage of Fruits and Vegetables Year-long supplies of fresh food have been made possible by improvements in controlled storage conditions, shipping and importing. A fresh weekly food supply at the local supermarket has eliminated the need for the home preservation and food processing of earlier days. Today, we may choose to preserve and.
