Pigments are important contributors to the appearance and healthful properties of both avocado fruits
and the oils extracted from these fruits.This study determined carotenoid and chlorophyll pigment
concentrations in the skin and three sections of the flesh (outer dark green,middle pale green,and
inner yellow fleshsnearest the seed) and anthocyanin concentrations in the skin of Hass avocado
during ripening at 20 °C.Pigments were extracted from frozen tissue with acetone and measured
using high-performance liquid chromatography.Pigments were also measured in the oil extracted
from freeze-dried tissue sections by an accelerated solvent extraction system using hexane.
Carotenoids and chlorophylls identified in the skin,flesh,and oil were lutein,R-carotene,â-carotene,
neoxanthin,violaxanthin,zeaxanthin,antheraxanthin,chlorophylls a and b,and pheophytins a and
b with the highest concentrations of all pigments in the skin.Chlorophyllides a and b were identified
in the skin and flesh tissues only.As the fruit ripened and softened,the skin changed from green to
purple/black,corresponding to changes in skin hue angle,and a concomitant increase in cyanidin
3-O-glucoside and the loss of chlorophyllide a.In flesh tissue,chroma and lightness values decreased
with ripening,with no changes in hue angle.The levels of carotenoids and chlorophylls did not change
significantly during ripening.As fruit ripened,the total chlorophyll level in the oil from the flesh sections
remained constant but declined in the oil extracted from the skin.
