Abstract

|
|
|
Fruits of ´Shinsui´ and ´Niitaka´ were kept in atmospheres of air or CA (2% O₂, 2% O₂ + 2.5% CO₂, 2% O₂ + 5% CO₂) at 0℃ and 5℃ for 24 weeks. Flesh firmness of ´Niitaka´ pears slightly decreased with the increase of storage duration and was significantly lower in fruits stored in air than CA at 5℃, However, there was no difference of firmness in ´Shinsui´ among storage conditions. Contents of soluble solids, titratable acids and juice pH were not affected by storage conditions. Hunter ´L´ and ´a´ values of fruit skin were significantly higher in fruits stored in air than CA conditions regardless of storage temperatures. Rate of oxygen consumption significantly higher in fruits stored in air than CA conditions at O℃ and 5℃ in both cultivars. Ethylene production in ´Shinsui´ significantly decreased in fruits stored in either 2% O₂ + 2.5% CO₂ or 2% O₂ + 5% CO₂ compared to air or 2% O₂ at 0℃ and 5℃, while ethylene production did not change in ´Niitaka´. Fruits stored in CA were enhanced firmness, skin color and reduced oxygen consumption or ethylene production in Asian pears.
