Key Points

To determine whether chlorophyll fluorescence and RGB color intensity can accurately and noninvasively track changes in chemical composition and antioxidant capacity throughout mulberry fruit development.
Monitored mulberry (Morus alba L.) fruits across all developmental stages (ST1–ST7) and late developmental stages (ST4–ST7).
Recorded noninvasive optical measurements using chlorophyll fluorescence and RGB color intensity values.
Quantified internal biochemical attributes, including total flavonoids, total phenols, sugars, and ABTS and DPPH radical scavenging activities, fitting correlation curves to optical data.
Chlorophyll fluorescence strongly correlated with internal chemical parameters during stages ST4–ST7, achieving R² values ranging from 0.82 to 0.94.
RGB intensity values showed high correlations with internal chemical parameters during stages ST4–ST7, with R² values ranging from 0.93 to 0.97.
Correlations between optical metrics and biochemical contents were consistently higher during late development (ST4–ST7) than across the full developmental cycle (ST1–ST7).
