สรุป	Fruit color analysis employs spectrophotometric measurement to quantify ripeness and quality based on chromatic properties. Using the CIE L*a*b* color space, introduced in 1976, this non-destructive method objectively grades fruit maturity and predicts sensory acceptability. It is widely applied in commercial sorting lines and research settings for precision quality control.	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.
