概要	Controlled atmosphere (CA) storage extends fruit shelf life beyond cold storage alone by actively regulating oxygen (O₂) and carbon dioxide (CO₂) concentrations during storage. By reducing respiration and ethylene production rates, CA storage can maintain fruit quality for months. This advanced technique is expensive but economically justified for premium fruit destined for long-distance export or extended market windows.	Ripeness index combines multiple quality measurements—soluble solids, firmness, color, starch degradation, ethylene production—into a single composite score indicating fruit maturity and harvest readiness. Unlike single-parameter metrics, this integrated approach accounts for cultivar variation and environmental influence to predict consumer acceptability more reliably. It is widely adopted in export industries and research settings to standardize harvest decisions.
