Estimation of Pulp Pigment Content Using Color Space Values in Guava
Guava fruits are a rich source of carotenoids, lycopene, and anthocyanin pigments. Colored guava fruits contain a higher concentration of these pigments in comparison to white pulped varieties. The aim of this study was to evaluate the suitability of color reader values for indirect estimation of pi...

| description | Guava fruits are a rich source of carotenoids, lycopene, and anthocyanin pigments. Colored guava fruits contain a higher concentration of these pigments in comparison to white pulped varieties. The aim of this study was to evaluate the suitability of color reader values for indirect estimation of pigment content in guava fruits. Using the CIELAB’s color space values (L*, a*, b*, C*, and h°), we quantitatively estimated the variations in pulp color (white, red, and purple) across 35 guava genotypes, including hybrids and germplasm. Using spectrophotometric methods, the contents of total carotenoids, lycopene, and anthocyanins were estimated, revealing significant discrepancies among the genotypes. The color value a* was positively correlated with total carotenoids (r
