Determination of fruit ripeness degree of ?Carabao? Mango (Mangifera indica L.) using digital photometry by Maja Sierhine J. Abarra, Edralina P. Serrano, Veronica C. Sabularse, Hervin Errol T.

Plots of R, B, V, and L* versus CI had correlation coefficients (R2) of 0.874, 0.915, 0.931 and 0.948, respectively. Titratable acidity (TA) and fruit firmness decreased with CI. Values of R2 for TA were 0.917, 0.915, 0.948, and 0.977 for R, B, V, and L*, respectively; corresponding values for firmness were 0.941, 0.933, 0.941, and 0.968. R2 of the binary and ternary color functions for TA were 0.924 and 0.947, respectively; corresponding values for firmness were 0.905 and 0.948, respectively. The results show that digital photometry ? using a simple digital camera and free-access software for color analysis based on RGB, HSV, or L*a*b* systems ? is a promising laboratory method for determining the ripeness degree of ?Carabao? mango fruits.
